During the "Twelfth Five-Year Plan" period, China's shale gas exploration and development made a major breakthrough, becoming the first country outside North America to achieve large-scale commercial development, laying a solid foundation for the "13th Five-Year Plan" industrialization development. The relevant person in charge of the National Energy Administration said that during the "13th Five-Year Plan" period, the new normal of economic development will promote the continuous optimization and adjustment of the energy structure, and the demand for clean energy such as natural gas will continue to increase, providing a strategic opportunity for the large-scale development of shale gas.
As China strengthens air pollution control, vigorously promotes a clean and low-carbon development strategy and actively promotes new urbanization, natural gas will play a greater role in adjusting and optimizing the energy structure.
The "Energy Development Strategic Action Plan (2014-2020)" issued by the General Office of the State Council clearly states that by 2020, natural gas will account for more than 10% of China's primary energy consumption. The development of shale gas is in line with China's energy development trend.
The rich resource base and good industrial start provide a solid guarantee for the development of shale gas in China. During the “Twelfth Five-Year Plan†period, China’s shale gas development achieved breakthroughs in the southern marine system, and the shale gas in the Sichuan Basin achieved large-scale commercial development. Many other favorable areas obtained industrial test airflow, and the South China Sea Longmaoxi Formation shale gas resources and The development potential is strongly confirmed. At the same time, China has basically mastered the efficient development technology of 3,500 meters of shallow sea shale gas, and will provide strong technical support for the accelerated development of the “13th Five-Year†shale gas industry.
It is understood that China's shale gas wells have a large investment in single wells, and the production declines rapidly. The stable production of gas fields requires a large number of wells for indirect replacement. Therefore, the investment in shale gas development is large, the implementation period is long, and there are many uncertain factors. It has great financial pressure and investment risk for shale gas development enterprises.
At the technical level, deep development techniques are not yet in place. The development of shale gas resources with a depth of more than 3,500 meters requires higher requirements for horizontal well drilling and completion and production and transformation technology. Insufficient competition in exploration and development is another major problem. The mineral rights of the shale gas favorable area overlap with the registered conventional oil and gas mineral rights, and the conventional oil and gas mining rights withdrawal mechanism is imperfect, and it is difficult to exert the advantages of shale gas independent minerals.
With the decline in the prices of traditional fossil fuels such as oil and coal, the competitiveness of natural gas has declined, and consumption growth has slowed markedly. At the same time, domestic natural gas production has grown steadily, and a series of long-term import agreements for natural gas such as Sino-Russian, Central Asian, and Central American liquefied natural gas (LNG) have been signed, and the natural gas supply capacity will increase significantly in the future. According to experts, according to the current energy consumption structure, natural gas supply during the “13th Five-Year Plan†period is generally sufficient.
In the long run, shale gas development is of great significance to promoting China's scientific and technological progress, driving economic development, optimizing energy structure and ensuring energy security. To this end, the "Planning" defines four key tasks for the future development of shale gas:
Advance scientific and technological research. Following the new trend of shale gas technology revolution, we will overcome the exploration and development bottleneck technology of shale gas reservoir evaluation, horizontal well drilling and completion, stimulation and gas reservoir engineering, and accelerate the upgrading of existing engineering technology.
Hierarchical layout for exploration and development. The national shale gas block will promote exploration and development in three different ways according to key construction, evaluation breakthrough and potential research.
Strengthen the construction of national shale gas demonstration zones. During the “Thirteenth Five-Year Plan†period, the construction of four national-level shale gas demonstration zones in Changning-Weiyuan, Fuling, Zhaotong and Yan'an will be further strengthened, and the effective development technology, efficient management mode and applicable system of shale gas will be improved and promoted through experiments and demonstrations. Mechanisms, etc.
Improve infrastructure and markets. According to shale gas production capacity construction and national natural gas pipeline network construction and planning, support shale gas access pipe network or nearby use. Encourage all kinds of investment entities to enter the shale gas sales market, and gradually form a market pattern in which multiple entities such as shale gas mining enterprises, sales enterprises and urban gas-operated enterprises coexist.
