Domestic shale gas reserves are huge, but exploration and development are facing technical and other challenges. There is a sleeping lion. If you know that it is powerful, you just cannot wake it up. What should I do? This is the mood of the National Committee of the Chinese People's Political Consultative Conference and Chen Yan, Dean of the China Petroleum University (Beijing) Petroleum Engineering College. In an interview with this reporter, Chen Hao said that in the past, he took things from others and copied them to learn other people's skills. However, for shale gas and other unconventional oil and gas resources, "taking in" is totally inapplicable. " This lion is too fierce and needs unconventional means!"

Coincidentally. On the *****, the representative of the National People's Government and Li Lianwu, director of the Henan Petroleum Exploration Bureau, also proposed that China's crude oil dependence on foreign markets has risen sharply, and it is urgently needed for new energy alternatives to supplement the growing demand. He suggested increasing support for the exploration and development of non-conventional energy sources.

The energy supplementation with huge potential can be seen as a substitute for two sets of data: In 1993, China became a net oil importer, and its foreign dependence on oil increased to 56.5% in 2011. It exceeded the international oil security warning line (50%) for three consecutive years; The evaluation agency reported that the output of shale gas reservoirs in China is expected to be 21.5 trillion cubic meters - 45 trillion cubic meters. The latest forecast by the US Energy Information Administration (EIA) shows that China's technically recoverable shale gas reserves are 36.1 trillion cubic meters, far. Super-ranked second in the United States (24.4 trillion cubic meters).

“The potential of unconventional oil and gas resources is self-evident,” Chen Xi told reporters. Apart from the conventional resources that currently account for the development of oil and gas energy, shale gas, coalbed methane, tight gas, tight oil and other unconventional resources gradually Having attention.

The "quiet" shale gas has already had a profound effect on the world energy situation. For example, in the United States, which achieved large-scale commercial exploitation, shale gas production exceeded 100 billion cubic meters in 2010. Its shale gas production has grown more than 20 times in the past five years, accounting for one-fifth of the country's total natural gas production.

“Stanford University research report shows that shale gas development can guarantee 100 years of US natural gas supply, and the United States has thus become a self-sufficient or even exporting country from a natural gas importing country.” Chen Yu said that unconventional oil and gas resources are between traditional energy and solar energy. Between new energy such as wind energy and wind power, energy is a step away from the world. "In the case of China, where the gap in oil and gas resources is widening, it is extremely urgent to develop unconventional energy sources."

"The stone of other hills" can't take a step forward? This step is not small! Unconventional oil and gas must be "acquired" by special means.

Li Lianwu analyzed that the exploration and development of domestic unconventional energy started late, the theory was not mature, and the technology was not in place. The exploration and development of unconventional oil and gas resources require high technology and high costs. It requires not only resource evaluation and identification technologies, but also drilling techniques under complex structural conditions, as well as different fracturing technologies for different reservoirs. Regardless of technology, scale, level, or speed of development, China is at a very early stage.

“More importantly, the molding technology in developed countries is not applicable to us.” Chen Xi cited the example of the United States’ two recognized technologies for shale gas exploration and development: large-scale hydraulic pressure and horizontal well technology. With the former, each horizontal well is about 100,000 gallons of water, which is not a problem for the relatively abundant water resources of the United States. However, shale gas in China is mostly distributed in water-deficient areas such as Xinjiang, Inner Mongolia, and Songliao, and it can only be satisfied with foreign technologies. Small-scale experimental development; as another example, thanks to the congenital advantages of abundant land resources, the United States has realized low-cost, factory-style development of shale gas. They drilled a railroad and quickly transferred the rig to another after drilling a well. There is almost no waiting time for drilling in one place – this is unlikely to be replicated in the southwestern region, where domestic shale gas is relatively abundant but hilly and hilly.

“In the initial stage of research and development for discovery, there is no need to think too much about the cost. Once it enters a large-scale promotion, similar problems will emerge in an endless stream.” In Chen’s opinion, without forming its own technical system and original innovation, China’s fundamental “cannot "Unconventional oil and gas.

Policy-led acceleration of basic research “Our geological evaluation has been started and industrial test wells have been put into use, but we are very ignorant.” Li Lianwu believes that the relevant state departments should expedite the formulation of relevant policies to reduce unconventional oil and gas resource taxes with fiscal subsidies. Support enterprises to increase investment in science and technology, and then reduce the exploration and mining costs of unconventional oil and gas resources.

Chen Zhen proposed in the CPPCC proposal that the State Development and Reform Commission and the Ministry of Science and Technology take the lead in coordinating with shale gas development related enterprises, and combine China's unique characteristics of shale gas development, and set up joint ** for national research institutes, universities and colleges, etc. Encourage exploration of basic research on shale gas exploration, development, and application that suits the national conditions. “National policies are used to guide basic research.”

“At the moment, both the American Institute of Technology and the university’s petroleum majors all regard shale gas as an important topic, and the proportion of our international students in the United States, including Chinese who work or do research in the United States, is increasing.” The national talent introduction project devoted exclusively to non-conventional energy talent projects, and used flexible and diversified policies to attract overseas high-level technical talents who had “eaten this bowl of rice”. “Now, the country has not even hit specific problems, but they are very Clear 'What's in the bowl' - they have the ability to cultivate talent at home. They may be the first heroes to wake the sleeping lions!"
