At present, China is in the period of accelerated development of industrialization and urbanization, and the demand for energy is also accelerating. With coal-based energy structures, energy demand and environmental pressure are increasing. As the largest oil and gas production enterprise in China, China National Petroleum Corporation takes on the responsibility for energy structure adjustment, commits itself to the development and utilization of natural gas, and initially forms a gas-based clean energy development and utilization system, which bears the historical mission of reforming China's energy structure.

Optimizing energy structure is the inevitable choice

China is now in a period of rapid growth in energy demand. It is difficult to fundamentally change the energy consumption structure dominated by fossil energy in the short term, and China's oil and gas production still has good prospects for development. Among them, natural gas as a high-quality clean energy has the most promising development prospects.

From Shaanxi to Shanghai, from Tarim to Chengdu. In August, the newspaper’s interview team flew more than half of China and interviewed on-site natural gas production and supply. Whether it is oil and gas production, pipeline construction or terminal supply, CNPC attaches more and more importance to natural gas, and natural gas has become China's most powerful field of oil.

According to Jiang Jiemin, general manager of China National Petroleum Corporation, China is in a phase of rapid growth in energy demand. Energy-based energy-consuming structures based on fossil energy cannot be fundamentally changed in the short term. China's oil and gas production still has good prospects for development. Among them, natural gas as a high-quality clean energy has the most promising development prospects.

Relevant experts also agree with this view. Professor Liu Yijun of the China University of Petroleum said: "Natural gas is the key to China's energy structure adjustment and the completion of energy conservation and emission reduction targets in 2020."

Natural gas is called “clean energy in the 21st century.” According to calculations, natural gas emits 43% lower CO2 than coal and 28% less than oil.

Liu Yijun pointed out: "At present, China's energy-saving and emission-reducing pressure is very large, and the energy industry must make major breakthroughs in low-carbon energy to achieve energy-saving and emission reduction targets. At present, China's new energy development is still in its infancy, and vigorous development of natural gas is The best choice for China to reduce carbon emissions in primary energy consumption."

At present, China's natural gas consumption is still far from enough. Liu Yijun said that from the current global energy consumption structure, fossil energy accounts for about 88% of the world's primary energy consumption, including 33% of oil, 29% of coal, and 24% of natural gas.

In China's primary energy consumption structure, the proportion of natural gas consumption is only about 4%, which is one-sixth of the world average and one-twelfth that of Europe and the United States. At present, the per capita natural gas consumption in the world is 508 cubic meters per year, which is more than eight times that of China's per capita consumption. The potential for natural gas development in China is still very large.

Jiang Jiemin said that it is expected that natural gas may surpass coal to become the world’s second-largest energy source by 2030, and even exceeds oil to become the largest energy source. As China's natural gas consumption demand grows, the proportion of natural gas in the primary energy consumption structure will increase to around 10% by 2020. This kind of fast-growing demand will surely have a great effect on the production and supply of natural gas.

PetroChina has a good resource base for accelerating the development of natural gas business. At the same time, the development of natural gas is also in line with the adjustment of the company's business structure. It is also the best entry point and realistic approach for PetroChina to promote a low-carbon economy. CNPC will comprehensively increase natural gas development from production, pipeline construction and terminal supply.

Natural gas becomes the most growth business

At present, CNPC has produced 83% of the country's total natural gas, and natural gas has become China's most growth-oriented business.

At the beginning of this year, CNPC proposed to build a "green, international, and sustainable PetroChina" at the 2011 work conference for the deployment of the "Twelfth Five-Year Plan" work for CNPC. The connotation of green PetroChina is to highlight the development of natural gas, and at the same time take a green approach. Provide energy.

The oil and gas resource structure of CNPC is undergoing major optimization. During the “Eleventh Five-Year Plan” period, CNPC highlighted the “oil and gas simultaneous” strategy. Natural gas production has exceeded 30 billion cubic meters since 2005, and has maintained rapid growth of more than double digits for seven consecutive years. It has replaced the “hundred” position for four consecutive years.

In 2010, China's oil and natural gas production reached 72.5 billion cubic meters. At present, the proportion of CNPC’s natural gas production in total oil and gas production has increased from 12.4% in 2000 to 35.4% in 2010, making it the most growth business and forming three annual productions in Tarim, Changqing and Southwest oil and gas fields. In the 10 billion cubic meters of atmospheric area, as well as three medium-sized gas regions in Qinghai, Xinjiang, and Daqing, natural gas production doubled in five years.

At the end of the “Twelfth Five-Year Plan” period, China National Petroleum Corporation (CNOOC) will build 4 gas fields with reserves exceeding 1 trillion cubic meters. By 2015, the output will reach 120 billion cubic meters, accounting for 50% of the company’s domestic total equivalent of oil and gas. "Half the country."

The relevant person in charge of CNPC said that at present, CNPC has produced 83% of the country's total natural gas, from the West-East Gas Pipeline to the second-line, Shaanxi-Beijing Pipeline from the first line to the third line, the Shibuya-Ninglang-Jiangsu LNG, and every three people in the country. One person uses natural gas for exploration, development and transportation of China Petroleum.

Experts said that at present, the conditions for the large-scale development and utilization of natural gas in China are ripe. From the perspective of domestic reserves, China’s conventional natural gas recoverable resources amounted to 22 trillion cubic meters. By the end of 2009, the cumulative proven natural gas geological reserves stood at 6.32 trillion cubic meters, the proved rate was only 21.1%, and the storage and production ratio remained at a relatively high level. , with continuous exploitation of the resource conditions.

In order to further strengthen the guarantee of natural gas supply and ease the tension during the peak period, PetroChina will further emphasize peak capacity. Zhang Minglu, chief geologist of Changqing Oilfield Company, said: “In response to the frequent occurrence of “gas shortage” in China in recent years, increasing the construction of gas storage facilities and increasing peak capacity are also one of our priorities for the future.”

At present, China Petroleum has built a gas storage capacity of only 1.7 billion cubic meters, and its capacity for peak shaving has become a bottleneck for safe and stable supply. In the next step, based on international experience, China Petroleum will further strengthen the accurate estimation of strategic reserve needs based on the analysis and calculation of domestic demand for regular peaking, in accordance with the eastern target market peaking, the strategic reserve of the hub gas area, and the adjustment of western gas production At three levels, we started the evaluation and construction of 10 gas storages of 6 oil and gas field companies, such as Liaohe Oilfield, as soon as possible, and strived to meet the peaking and strategic reserve requirements.

Vigorously expand unconventional natural gas

The development of unconventional natural gas and new energy is an important way for CNPC to promote a low-carbon economy, and it is also an indispensable part of the comprehensive international energy company's business structure.

At the southwest oil and gas field headquarters in Chengdu, Sichuan, Liao Shimeng, deputy general manager of Southwest Oilfield Company, briefed the reporter on the current development of shale gas in China. “Since China's existing natural gas production cannot meet the needs of the rapid development of the national economy and society, it is urgently needed. At the same time, North American shale gas exploration and development have achieved great success, which has given us a lot of inspiration. The development of shale gas has begun to attract the attention of the government, various enterprises and people. The development of shale gas in China has entered the start At the same time, our Southwest Oil & Gas Field Company has also been working to explore and develop unconventional energy sources such as shale gas."

The natural gas industry has a rapid development momentum and is expected to be promising in the future. However, compared with the huge market demand, there is still a large gap. According to the forecast of the International Energy Agency, the demand for natural gas in China will increase to 444 billion cubic meters by 2030. There is a huge gap in the current growth rate of domestic production. How to make up for this gap? First, the introduction of foreign gas to make up for the lack; Second, increase domestic resources development efforts, including conventional gas, unconventional gas development.

The so-called unconventional natural gas refers to natural gas that is difficult to be extracted by conventional techniques because of relatively complicated storage conditions. CBM, shale gas, and natural gas hydrates (flammable ice) are all unconventional natural gas.

“China’s unconventional natural gas resources are abundant and the development prospects are encouraging. If we can develop and utilize various types of natural gas resources, it will play a positive role in ensuring the supply of natural gas in China. The most important thing to do now is to do a good job of long-term planning. Start, seek development, start with technology development, lay a solid foundation for development, gradually form a scale, effectively develop and utilize unconventional natural gas, and fully tap the potential of unconventional natural gas resources in China, said Zeng Xingqiu, former chief geologist of Sinochem Group.

Jiang Jiemin stated that the development of unconventional natural gas and new energy is an important way for CNPC to promote a low-carbon economy, and it is also an indispensable part of improving the business structure of a comprehensive international energy company.

According to the company's plan, during the “12th Five-Year Plan” period, China National Petroleum will actively develop unconventional oil and gas resources. The CBM must base itself on Surabaya and the Ordos Basin to accelerate the construction of industrial bases and promote the development of scale. By 2015, the proven geological reserves will exceed 500 billion yuan. Cubic meters, with an annual output of more than 4 billion cubic meters; shale gas to strengthen resource exploration evaluation, do a good job of industrialization demonstration area construction, to explore the geological reserves of 100 billion cubic meters by 2015, control of reserves of 300 billion cubic meters, annual output It reached 500 million cubic meters.

Glossary

liquified natural gas

LNG (Liquefied Natural Gas), the abbreviation for Liquefied Natural Gas. Natural gas is a combustible gas that is naturally mined in the gas field and consists mainly of methane. LNG is condensed into a liquid by cooling the gaseous natural gas at atmospheric pressure to -162°C. After liquefaction of natural gas, it can greatly save storage space and costs, and has large calorific value and high performance.

LNG is a clean, efficient energy source. Since imported LNG can help energy-consuming countries achieve diversified energy supply and ensure energy security, export LNG helps natural gas-producing countries to effectively develop natural gas resources, increase income, and promote national economic development. As a result, LNG trade is becoming a global energy source. New market hotspots.

Underground gas storage

Underground gas storage is a method of storing natural gas. The underground gas storage is generally deep underground, and a completely enclosed structure is found. Natural gas is pumped into the structure and stored in the ground. When necessary, natural gas is also produced from the production well to the surface and delivered to the user.

Underground gas storage has the following advantages: First, it has a large amount of gas storage; second, it has a high safety factor, and it is not easy to cause fires and explosions; Third, it has good economic benefits, and has a low gas storage cost compared with metal gas cylinders; Fourth, it has strategic significance. Covertness and security are suitable for strategic reserves.

shale gas

Shale gas, a natural gas extracted from a shale formation, is an important unconventional natural gas resource. The formation and enrichment of shale gas have their own unique characteristics, and they are often distributed in shale source rock formations with large thickness and widely distributed in the basin. Compared with conventional natural gas, shale gas development has the advantages of long mining life and long production cycle. Most gas shales are widely distributed, have large thickness, and are generally gas-bearing, which makes shale gas wells stable for a long time. Rate gas production.

CBM

Coalbed methane refers to the presence of hydrocarbon gas with methane as the main component in the coal seam, mainly adsorbed on the surface of coal matrix particles, partially free of coal pores, or dissolved in coal seam water, and is a coal associated mineral resource. Natural gas is a clean, high-quality energy and chemical raw material that has risen internationally in the past decade or two. CBM can be used as civilian fuels, industrial fuels, power generation fuels, automotive fuels, and important chemical raw materials, and has a wide range of uses.
