Understanding and Suggestions on Management of Company’s Major Science and Technology Projects Fu Chengde, Niu Liquan, Fan Xianghong, Zong Liu, Yang Baoying, Fu Xiaoqing 2018, 37(6): 1-5.  DOI: 10.3969/j.issn.1002-302x.2018.06.001 Abstract ( )   PDF (1181KB) ( )   The enterprise-oriented major science and technology projects aim at helping enterprises solve their key production technological bottlenecks. Focusing on application of new technology for production, the projects of this kind are characterized in multiple disciplines, high investment, short cycle and large teams. In the follow-up service of CNPC’s major science and technology projects, the latest six years in particular, it is found that there are still a series of problems in the design and management process of major science and technology projects, such as inadequately perfect top-level design, less prominent key technology and innovation, and the process management left much for improvement. To keep management of major science and technology projects continually improved, it is proposed to further strengthen top-level design, focus on the leading items of key technology, formulate the strict technical and economic assessment indicators, clarify the responsibilities and leading roles of chief researchers, form a unified deployment in the overall layout, make progressive developments in three “mature” stages -- technological research, perfection of the system, and large-scale application, and set up a clear objective for industrialization of key technology.

Analysis of Factors Influencing Sustainable Natural Gas Industrial Development in Sichuan-Chongqing Region Li Xue, Yu Xiaozhong, Zhong Shuli 2018, 37(6): 6-13.  DOI: 10.3969/j.issn.1002-302x.2018.06.002 Abstract ( )   PDF (1279KB) ( )   China’s natural gas demand has risen rapidly in recent years. The natural gas industry takes advantage of the good opportunity for dynamic development of clean energy. The Sichuan-Chongqing region is rich in natural gas resources with a market maturity and enjoys favorable industrial policies, thus stimulating rapid growth in natural gas production and consumption. However, the industrial development faces a series of problems in the areas of economic feasibility, technological development bottlenecks, industrial management and social ecology. Since natural gas is the basic industry in the Sichuan-Chongqing region, the study proposes to make a unified plan for the industrial development, deregulate natural gas market, and make greater efforts for exploration and development. It is also proposed that shale gas production should be accelerated at the time of keeping conventional natural gas production stable. Those suggestions are of valuable reference for sustainable natural gas industrial development in the Sichuan-Chongqing region.

Analysis and Suggestions on Basic Research Problems Made by China’s Central SOEs Shi Shude, Li Xin 2018, 37(6): 14-18.  DOI: 10.3969/j.issn.1002-302x.2018.06.003 Abstract ( )   PDF (968KB) ( )   It is of great strategic significance to support some central State-owned enterprises (SOEs) which are the industrial leaders committed to build themselves into the world’s first-class enterprises. The purpose is to improve their original innovative capability and solve the problem that China’s key core technologies are controlled by other countries. The study points out that central SOEs face some problems at the present time, such as inadequate basic research capability and insufficient supply of innovative technologies. Those problems can be attributed to four reasons -- lack of elite scientists, inadequacy of stable basic research investment, lack of special basic research institutions, and lack of original creative achievements to drive basic research. There are four main factors causing those problems, such as tobe- improved motivation, unscientific management methods, restrictions from the talent system, and lack of freedom in cultural exploration. It is proposed that the governmental department should make greater efforts for guidance, optimize the performance-examining system, try to establish a fund for guidance, and optimize the auditing work. It is also proposed that the central SOEs should launch relatively independent research institutions, set up a flexible management mechanism, create the conditions to attract scientists, and bring about a harmonious scientific research environment.

Analysis and Enlightenment of One-trip Drilling Cases of Shale Horizontal Well Yang Jinhua, Guo Xiaoxia 2018, 37(6): 32-35.  DOI: 10.3969/j.issn.1002-302x.2018.06.006 Abstract ( )   PDF (1463KB) ( )   In 2017, Baker Hughes used only three and a half days to complete drilling of a shale horizontal well with a depth of 5405 meters in DJ Basin, Wyoming State, USA. This paper analyzes the experience of this well’s success, including optimization of wellbore structure, application of high-efficiency drilling bit, use of oil-base drilling fluid for angle buildup section and horizontal section, application of buildup rate RSS, intensified drilling parameters, and use of the remote decision-making center. In the drilling of shale horizontal well in the United States, one-trip drilling is quite common for single well section, widely used for dual well sections and on the rise for multiple well sections. As a result, the drilling period is significantly shortened while the drilling cost is dramatically reduced. One-trip drilling is a project of system and also a key project for drilling horizontal wells at a higher speed and a lower cost. China is left behind in application of one-trip drilling technology as compared to the United States. It is necessary to pay attention to the necessity and likeliness of one-trip drilling and promote application of this technology. It is necessary to adopt a series of technological and managerial measures to promote large-scale shale gas development, such as optimization of drilling plan design, application of good-quality and high-efficiency drilling bit, release of promotion and incentive methods, establishment of information sharing platform, and modernization and remote decision-making center.

Method for Calculation of Oilfield Profit Production Guo Fujun 2018, 37(6): 36-39.  DOI: 10.3969/j.issn.1002-302x.2018.06.007 Abstract ( )   PDF (1273KB) ( )   The oilfield evaluated the economic performance of a single well in order to make a reasonable plan for production targets and optimize the oilfield production. Based on the economic characteristics of the oilfield production, the profit production is divided into the profits from new wells, old wells and stimulation measures. The method for calculation of a new well’s profit production is cash flow method, which takes a new well as a construction project and evaluates its economic performance. It is focused on construction scale of productivity and the new well’s production of the year at the time of net present value. The method for calculation of an old well’s profit production is single-well contribution value method, which evaluates the contribution to the economic performance of the oilfield from a single well’s revenue with the changing cost deducted. It is focused on the old well’s production at the time of its maximum profit. The research method for economic production from the stimulation measures is based on the input-output model to evaluate the economic performance of additional value from the stimulation measures. It is focused on the stimulated production at the time of maximum profit. This paper comes up with the calculation models of the oilfield profit production for new wells, old wells and stimulation measures. Those models help the oilfield bring about good economic performance of production, solving the problem that the oilfield only focuses on production target while neglecting the economic results in its production plan.

Situation Analysis and Development Suggestion of Global Oil and Gas Exploration Liu Xiaobing, He Zhengjun, Ji Zhifeng, Wan Lunkun, Wen Zhixin, Wang Zhaoming, Wu Yiping 2018, 37(6): 48-52.  DOI: 10.3969/j.issn.1002-302x.2018.06.009 Abstract ( )   PDF (2027KB) ( )   Investment for global oil and gas exploration reached US$43.4 billion in 2017, while 3D seismic acquisition was 31.3×104km2. A total of 1445 exploratory wells were drilled worldwide, rising substantially as compared to 2016. Meanwhile, there were 256 newly discovered conventional oil and gas fields in the world and the newly additional conventional oil and gas 2P recoverable reserves reached 14.5×108t oil equivalent, a slight increase over 2016. Under the situation of low oil prices, oil and gas exploration has been continually shifted towards mature basins, maintaining a relatively high exploration success rate and a relatively low cost for exploration discovery. The newly-discovered oil and gas reserves are located mainly in the three types of basins -- passive continental margin basin, foreland basin and rift basin. They are concentrated in 13 main areas. Meanwhile, a series of important discoveries have been made in the frontier areas like the deep water and ultra-deep water areas. The enduring investment has brought oil companies significant returns. It is proposed that the Chinese oil companies should appropriately increase exploration investment, extensively acquire exploration blocks in the different areas by means of various channels, and step up “the Belt and Road” oil and gas cooperation. Attention should be focused on the deep to ultradeep water and natural gas areas in the near future.

Development Trends and Strategies of Global Oil Companies’ Exploration and Development Business Wang Jianjun, Zhang Ningning, Wang Qing, Li Haowu 2018, 37(6): 53-60.  DOI: 10.3969/j.issn.1002-302x.2018.06.010 Abstract ( )   PDF (1492KB) ( )   The global oil and gas market, as a whole, has maintained a good trend since 2017 with international oil prices climbing significantly. Most of petroleum companies have re-positioned themselves for strategic growth. To make an in-depth and comprehensive understanding of those companies’ successful methods and experiences, this study selects 40 companies of three main kinds -- international oil companies, national oil companies and independent oil companies -- as the research targets. Based on comparison of the different kinds and analysis of the typical cases, the study focuses on the development characteristics of those oil companies, such as their business dynamics, development strategy, and optimization of assets portfolio. The study indicates that companies of the different kinds have different development characteristics. International oil companies have a strong momentum for their upstream business growth, leading the industry to resume quickly. National oil companies have their own remarkable development characteristics. They are quite different from one another in business growth owing to shortage of capital. Independent oil companies continually focus on their core businesses with the growth engine coming from their specializations. Oil companies pay more attention to both long-term and short-term objectives for business development and highlight actual economic performance, thus leading to active acquisitions in the upstream sector and outstanding performance in the areas of oil sand, tight oil and gas, and deepwater operations. Meanwhile, oil companies are actively set for natural gas and renewable energy businesses and modernize themselves by means of organizational restructuring.
