Reform of China’s Oil and Gas Reserves Management and Suggestions on Reserves Management of Oil Companies Tian Jun, Dong Yuexia, Fu Ling, Li Feng, Wu Sujuan 2023, 42(5): 1-6.  DOI: 10.3969/j.issn.1002-302x.2023.05.001 Abstract ( )   PDF (2098KB) ( )   Reform of oil and gas reserves management is an important part of China’s energy system reform. In recent years, the reform has been focused on such areas as revision of the national standards and industrial technological specifications on resources/reserves, simplification of the record procedure for appraisal, and enhancement of information release and supervision concerning statistical data and encouragement of the third-party estimation. This round of reform is mainly characterized for further clarification of the nation’s position and principal responsibilities in reserves management. While meeting the new situation of the oil and gas industrial development, the nation established the environment for market-oriented arrangement of oil and gas resources. Focusing on reform of oil and gas reserves at home, the oil companies should position themselves for further market-oriented reserves management under the new situation and new industrial trend. Meanwhile, they should bring the reserves under detailed management in the pursuit of the two goals – creating the value of reserve asset and keeping the company’s sustainable development. Taking into account the deteriorating trend of reserves, this paper proposes that resources/reserves management of oil companies should center on economically recoverable reserves, highlight the attributes and value-creating abilities of reserves asset, and bring reserves and production business under integrated management. In addition, it also proposes to enhance evaluation of reserves value, establish and perfect the value-estimating system for resources/reserves, study the resources/reserves flow mechanism, and further display the market role in resources allocation.

Important Role of Natural Gas in New Power System and Development Strategy Tang Hongjun, Li Yang, Li Xinyao, Wu Jiawen 2023, 42(5): 7-12.  DOI: 10.3969/j.issn.1002-302x.2023.05.002 Abstract ( )   PDF (1950KB) ( )   Construction of the new-typed power system based mainly on new energy holds the key to realization of the carbon peak and carbon neutrality goal. China’s installed capacity of wind and solar power was accumulated to 7.6×108kW by the end of 2022, accounting for 29.6 percent of the nation’s total installed capacity. This proportion is estimated to reach 45 percent in 2035. With a high proportion of new energy included into the power system, its flexibility and stability will face a huge challenge. Natural gas power generation is flexible, high-efficiency, quick for startup and stoppage, strong for variable load capacity, but carbon emission is less than half the amount discharged from coal-fired power. Therefore, natural gas is the important area for optimization of electric power structure and reduction of carbon emission. It can be used as the most flexible power source for peak adjustment in the power system, thus accelerating large-scale development of new energy like wind energy and photovoltaic energy. Currently, the key factors affecting China’s natural gas-fueled electricity generation include the unclear state policies, the pressure in regional gas supply in winter, and the dissatisfactory economic performance. This paper comes up with the suggestions on acceleration of natural gas development and clarifies the position of natural gas power generation in the base load supply and peak adjustment of the new-typed power system for the purpose to improve safety and flexibility of the new-typed power system. It is proposed to make a unified plan for integrated development of natural gas with new energy to establish the demonstration base of the “gas, wind, photovoltaic and hydraulic” integration, accelerate construction of the natural gas emergency guarantee system to secure the supply, and set the appropriate prices of gas, electricity and carbon with the applicable policy mechanism so as to keep the new-typed power system in safe and stable operation.

Discuss Development Law of Oil and Gas Exploration Zhang Feiyan, Guo Yuanling, Wang Huiyong 2023, 42(5): 21-29.  DOI: 10.3969/j.issn.1002-302x.2023.05.004 Abstract ( )   PDF (2982KB) ( )   The development law of exploration is a theoretical understanding of the guidance thinking and practice experience in the process of each exploration stage. The paper makes analysis and discussion mainly in three areas – breakthrough in new areas, increase of reserves in old areas and exploration capability. According to this paper, the exploration success in the new areas depends mainly on abundance of resources, complication degree of geological conditions, correctness of the direction for exploration breakthrough, understanding degree of the exploration breakthrough targets, and influence of the other factors, such as the work conceptions in the exploration process. The exploration efforts for increase of reserve in old area are controlled and influenced mainly by such factors as the potential of remaining resources, the reasonable structure between oil and gas discovery and increase of reserve, orderly replacement in the exploration field, and the work conception and attitude in the reserve-increasing process. Exploration capability is shaped in the theories. The guidance thinking of exploration means “oil in the brain”. The correct geological understanding does not mean making a scientific decision on exploration. Exploration management should aim at ensuring fulfillment of the geological tasks. It is proposed that the study at the next step should focus on analysis of the typical cases and analysis of the exploration process in the exploration areas. It is necessary to analyze the experience and understanding of the exploration predecessors and obtain the meaningful development law and theoretical knowledge through the efforts for statistics of data and summarization of experience.

A series of achievements were made in the practice from synergy among underground gas storage, oil displacement and geothermal utilization. (1) The buried-hill oil reservoir has a unique advantage for construction of gas storage depot. (2) The adjustment and control technology of the gas-injection speed can slowly expand the oil-gas interface and keep the oil-water interface stable, thus hopefully bringing about integration of EOR with peak-adjusting gas supply for the buried-hill reservoir. (3) Based on the existing plan of the oilfield, the geothermal wells, heat-exchanging stations and oilfield pipelines in the area are integrated to establish the closed-loop model of gas-injection development, residual heat recovery and re-injection for the buried-hill reservoir and make comprehensive use of multiple sets of geothermal resources and residual heat from the oilfield gathering and transferring facility. (4) Integrated construction of oil displacement, gas storage and geothermal synergy is experimented with the good results achieved. The predicted EOR is raised by more than 20 percent. The heat-supplying capacity of 205×104m2/a has been established in the central area of Hebei Province since the buried-hill geothermal energy was brought under development and utilization. The applied geothermal energy was equal to 5.11×104t of standard coal, reduced 14.15×104t of carbon dioxide, improved the abilities for comprehensive use of clean energy, and alleviated the heat-supply pressure.
