“Point-Line-Area” Methodology of Shale Oil Exploration and Development Liu He, Li Guoxin, Yao Zixiu, Jin Xu, Meng Siwei, Su Jian 2020, 39(2): 1-5.  DOI: 10.3969/j.issn.1002-302x.2020.02.001 Abstract ( )   PDF (1546KB) ( )   China is rich in continental facies shale oil resources, but the grade of resources is relatively poor as a whole. Exploration and development are left behind in this area. Technological innovation is an important way for shale oil development on a large scale and with efficiency. It is of vital importance to enhance execution and management of technological projects while the “point-line-area” methodology is used in innovation. It is necessary to select the appropriate “point,” clarify what holds the key to technological problems, find the main contradiction and the main aspects of the contradiction, and make full use of the limited resources. It is necessary to control the “line,” complete and perfect the control lines of programs for various items of main work, ensure connection of one stage with another, and keep from being fragmented in the work. The “area” should be expanded in the efforts to formulate the reasonable schemes for promotion and application, strengthen the efforts for technological integration and wider application, and accelerate transformation and industrialization of achievements. It is necessary to follow the process of cognition from research to practice and from “point” to “line” and then “area.” The efforts should be focused on basic research and settlement of the key technological bottlenecks and construction of the exploration, development and engineering integration platform with the information real-time updated and shared. Basic research and settlement of technological bottlenecks should be brought under programmed supervision, management and adjustment. It is necessary to establish the full life cycle organizational management pattern and step up the top-level design to guide construction of the shale oil demonstration zone, thus accelerating China’s shale oil industrial development.

Implement National Innovation-driving Development Strategy; Accelerate High-quality Oil and Gas Industrial Development Wang Zhen, Zhang An 2020, 39(2): 6-12.  DOI: 10.3969/j.issn.1002-302x.2020.02.002 Abstract ( )   PDF (1575KB) ( )   So far as the petroleum industrial development process of New China in the past 70 years is concerned, technological innovation is always the inexhaustible power to bring about development and brilliant achievements. The continental oil and gas geological theory in the 1960s got rid of the western “terrestrial lean oil” theory. Foreign technological blockade made China’s petroleum industry develop itself by means of independent innovation. The nation has gradually established its complete petroleum industrial system. Technological innovation helps petroleum enterprises implement the “go-world” strategy and use both Chinese and foreign resources to secure the nation’s energy supply, bringing about a leap forward development for the Chinese petroleum industry. Currently, China’s technological innovation still faces foreign technological monopoly, with some of the key and core technologies controlled by other countries. The technological innovation structuring mechanism and the relative systems are not functioning effectively while the resources for scientific research need to be further opened and shared. The achievements are not desirably transformed for application. The structure and ability of technological talents and professionals are not in line with high-quality development of the petroleum industry. Petroleum enterprise should make response to these bottlenecks and challenges. Acceleration of technological innovation is an inevitable option and an important foundation for participation in global competition and cooperation with international oil majors. It is also the fundamental solution to deterioration of resources grades and demand for high-end products. Focusing on high-quality development of oil and gas industry, this paper come up with the suggestions on implementation of innovation strategy, perfection of the technological innovation system and fostering of technological talents and professionals.

Opinions on China’s Chemical Industrial Development Against New Situation He Shengbao, Wang Hongqiu 2020, 39(2): 13-20.  DOI: 10.3969/j.issn.1002-302x.2020.02.003 Abstract ( )   PDF (2071KB) ( )   China is one of the main producers and consumers of chemicals in the world. With the newly-launched projects brought on stream by the private-owned enterprises like Zhejiang Petroleum & Chemical Co., Ltd. and the foreign-funded enterprises like ExxonMobil, China’s chemical market gradually comes under competition from a multiple of suppliers, such as giant State-owned petrochemical enterprises, coal chemical enterprises, privateowned petrochemical enterprises, local petrochemical enterprises, foreign-funded enterprise, Chinese-foreign joint ventures, and importers. Meanwhile, influenced by slowdown in global economic growth and concentrated release of newly-additional production capacity, the world chemical industry sees a profit decline and a stern situation. It is impossible for an enterprise to have competitiveness in the era of market globalization without adapting itself to the environmental changes. Speed, creation, high quality and cost-effectiveness hold the key to the new competitiveness that meets the environmental demand. China’s chemical industry should complete the transition from dependence on technological imports to technological independence, from the initial resource-processing stage to the middle and high stages, and from extensive management stage to fine management stage. Importance should be attached to the key bottlenecks affecting chemical industrial development at the State level and corporate level, such as lack of independent technology in the field of high-molecular materials, sternness of product homogenization, and heavy dependence on imports of high-end products.

Progress and Suggestions on CNPC’s Multinational Oil and Gas Exploration and Development Dou Lirong, Wang Wangquan, Xiao Wei, Lin Yuchen 2020, 39(2): 21-30.  DOI: 10.3969/j.issn.1002-302x.2020.02.004 Abstract ( )   PDF (2610KB) ( )   It is more and more difficult to find large conventional oil and gas fields worldwide in the past three decades. The offshore and unconventional oil and gas areas become the focus of exploration. Some national oil companies (NOC) have risen to become the main force for discovery of large onshore oil and gas fields. International oil companies (IOC) remain as the main force for discovery of large offshore deepwater oil and gas fields. Competition for global resources becomes more intense than ever. China National Petroleum Corporation (CNPC) has engaged itself in overseas exploration and development for 27 years and experienced three stages -- progressive exploitation, large-scale risk exploitation and rapid multi-element development. It has established five main oil and gas cooperative regions in the world. The overseas gross shared oil and gas production exceeded 1×108t oil equivalent in 2019, decreasing 6.7% of integrated import dependency (IID) in China and making important contribution for the country’s energy security. Facing a series of challenges, such as more intense international competition, complicated investment environment and harsh contract conditions, CNPC should expand its efforts to open up new projects, focus on the Belt and Road Initiative, increase investment for deepwater conventional oil and gas exploration and development projects and carefully involve itself into the unconventional projects. In addition, the company should increase technological investment, enhance operation of exploration assets, improve economic performance of the exploration projects, launch risk exploration fund, and step up multi-company joint operation.

Present Conditions and Prospect of Global Deepwater Oil and Gas Exploration and Development Wang Luxin, Pan Jiping, Yang Lili 2020, 39(2): 31-37.  DOI: 10.3969/j.issn.1002-302x.2020.02.005 Abstract ( )   PDF (2068KB) ( )   Rich in oil and gas resources, the deepwater area has been the hot spot for global oil and gas exploration and the main source for increase of reserves and production in recent years. The rapidly-developed offshore technology and engineering equipment have dramatically improved the capacity for deepwater oil and gas exploration and development. The preferential policies have also accelerated the deepwater oil and gas exploration and development process. The deepwater area of the South China Sea is low in the oil and gas exploration and development degree but has a great potential for oil and gas resources. It is the favourable target zone in search of large oil and gas fields in the future. Currently, a total of 14 large and medium-size deepwater oil and gas fields have been cumulatively discovered in the northern part of the South China Sea. This article is focused on the problems of resources, technology and cost existing in China’s deepwater oil and gas exploration and development. It comes up with a series of suggestions, such as enhancing offshore oil and gas geological investigation and evaluation for public interests, developing systematic deepwater exploration and development engineering technology and equipment, stepping up international cooperation in the field of oil and gas resources, and promoting cooperation and common development on the basis of independent development.

The results from evaluation can directly reflect the comprehensive level of the completed technological project. Therefore, establishment of a objective and reasonable post-evaluation indexes system for the technological project is of vital importance to improvement of the post-evaluation quality for the technological project. Based on the main nodes of the operational period of the pipelines enterprises’ technological projects, this paper takes the application research projects for examples and constructs the post-evaluation indexes system of the pipeline technological projects on the basis of four areas -- investigation at the preliminary stage and launch of project, execution process, completion of the project, and promotion and application. It adopts AHP to quantify the evaluation indexes at each level, namely matching of the weight. The above-mentioned AHP-based post-evaluation indexes system was used to appraise the completed pipelines application research projects. The appraisal results are in line with the scientific law of normal distribution, confirming the scientific property and reasonableness of this post-evaluation indexes system of the technological projects. It is also confirmed that the post-evaluation indexes system can objectively reflect the comprehensive research level of the technological projects.

High-efficiency, Low-cost and Green Air Injection Development Technology of New Generation Liao Guangzhi, Wang Zhengmao 2020, 39(2): 59-66.  DOI: 10.3969/j.issn.1002-302x.2020.02.010 Abstract ( )   PDF (2425KB) ( )   Air injecting development technology has existed for a long period of time, but this technology has not been industrialized on a large scale because some problems have not been desirably solved, such as the quality of compressor and explosion easily caused by oil and gas mixture. Starting from 2009, PetroChina depended on the platform of important development experiment to test oxygen-reduced air flooding at low-permeability, water-sensitive and high water-cut old oilfields as well as buried hill oil reservoirs. The air injecting fire drive was also tested for heavy oil reservoirs. With designing at the top level, PetroChina cooperated with a number of units to study air injecting development mechanism of full temperature range from low temperature section to high temperature section. It also formulated the related standards, such as “Use Oxygen-reduced Air for Oil Flooding”. Based on the study of a dozen of years, PetroChina has made important breakthroughs in the air injecting development theory and owned a system of basically mature development technologies, with remarkable achievements of field experiments. Crude oil production is accumulated to 375×104t. Air injecting development technology is applicable to many types of oil reservoirs and many kinds of crude oil. The injected medium of air is free from the influence of the environment and climate while the components are stable. This technology is high-efficiency, low-cost, green and likely to become the strategic development technology with a great development potential for the oil reservoirs with the unconventional and special conditions, such as low permeability, high water cut, high temperature and high salt and heavy oil. Currently, it has been industrialized. The oil production will top 100×104t in 2020 and hopefully reach 400×104t by 2025.

New Methods for Optimized Investment Portfolio of Exploration Targets Liu Peng, Gao Le, Zhang Houhe , Gao Yangdong, Zhang Jingwei 2020, 39(2): 67-71.  DOI: 10.3969/j.issn.1002-302x.2020.02.011 Abstract ( )   PDF (1898KB) ( )   Traditional theoretical model of optimized investment portfolio for exploration targets includes the linear programming method, the integer programming method and the efficient combination method based on the Markowitz theory, but they do not integrate the actual work of domestic exploration and development, thus being unable to optimize the exploration and development process simulation. This problem can be better solved by means of the process simulation method, which combines the zone economic evaluation mode based on simulation of the whole exploration and development process with the efficient portfolio model based on genetic algorithms. It can be also applied to the development model and its engineering to evaluate offshore oil and gas exploration targets that are much more complicated than the onshore targets. The evaluation mindset of this method is based on the zone economic evaluation and sets a number of constraints so as to select the best target combination. With application of the genetic algorithm, the main steps include the zone economic evaluation and optimization of investment portfolio. Finally, the application cases are used to confirm the practicability o f this method.
