Inspiration from Establishment, Development and Innovation of Downhole Control Engineering Su Yinao 2019, 38(5): 1-7.  DOI: 10.3969/j.issn.1002-302x.2019.05.001 Abstract ( )   PDF (3052KB) ( )   To further improve controlling level and quality of hole trajectory and inspired by successful application of engineering control theory in missile guidance and space tracking, the author came up with the research area of “well trajectory control theory and technology” in 1988 and the conception of “downhole control engineering” in 1992. The author and his research team have continually made basic research and focused on technology and equipment in the area of downhold control engineering in the past three decades, achieving some relevant results. They opened up a new area of petroleum engineering, creating the science of downhole control engineering under the subject of “petroleum and natural gas engineering”. A series of downhole control systems, tools as well as high-end technologies and equipment have been independently and successfully developed, such as “CGDS-1geosteering drilling system” which is put into industrialized and mass application. The technology and equipment have substantially improved China’s international key competitiveness of drilling technology. This paper briefs about downhole control engineering in terms of framework, research scope, innovative theoretical and technological points and development orientation, displaying the powerful vitality of this emerging subject. Based on reviewing the technological and academic background of downhole control engineering and the technological innovation laws and methods, this paper points out that cross-discipline is an important method and a prominent characteristic of technological innovation while an excellent technological team is the backbone of technological innovation. Adherence is a guarantee for success of technological innovation and transformation and application serve as the criteria for success of innovation. Technological innovation should be examined by practice to prove correction of innovation. Theoretical and technological innovations should be finally transformed into production power, putting an end to the innovations.

Selection of Patent Operational Methods by Petroleum Enterprises and Study of Patent Operational Strategy Si Yunbo, Li Chunxin, Bi Yantao, Chen Ji 2019, 38(5): 21-26.  DOI: 10.3969/j.issn.1002-302x.2019.05.005 Abstract ( )   PDF (2247KB) ( )   The environment for the domestic patent operation has been improved in recent years owing to the efforts made by the government. The conditions for companies’ patent operation have been increasingly matured in the period of time. The patent operational characteristics of petroleum enterprises are determined by the special properties of petroleum industry. The amount of patent applications from China’s petroleum enterprises has risen dramatically in recent years, but the patent operational ability is relatively inadequate. Most of the patents have not been used or implemented effectively. Based on the existing studies, this paper aims to establish the evaluation method system for petroleum enterprises to select the patent operational methods so that the reference can be provided for the enterprises to reasonably select the operational methods. In the petroleum upstream sector, patent operation of the enterprises are mainly related to engineering services to improve values and revenues of engineering service, because the upstream technology is poor in description and highly dedicated to the conditions of the specific oil and gas resources. In the downstream and chemical sector, patent operation is relatively active and has a variety of operational patterns, because the technology in this area is close to markets, abundant in kinds and fast in modernization. It is proposed that the petroleum enterprises should study diversified patent operational methods and strategies, create the favourable policy environment for patent operational activities, and perfect the relative structuring mechanism to promote a healthy development of patent operation.

Analysis of “Bottleneck” Technology in China’s Oil and Gas Engineering Area and Suggestions on Countermeasures Guang Xinjun, Wang Minsheng, Ye Haichao, Pi Guanglin 2019, 38(5): 32-39.  DOI: 10.3969/j.issn.1002-302x.2019.05.007 Abstract ( )   PDF (3626KB) ( )   Currently, many core technologies in China’s area of oil and gas engineering have remained as short boards and bottlenecks, restricting the country from raising its oil and gas production. The recoverable resources and the economic property of production depend on oil and gas engineering technology and equipment. Oil and gas engineering technology plays a more and more important role in increasing reserves and production, reducing cost for higher efficiency and promoting transformation and upgrading of oil and gas exploration and development. “Bottleneck” technologies in China’s oil and gas engineering area mainly include fine exploration technology, deepwater oil and gas engineering technology, ultrahigh temperature downhole tools, high-performance intelligent steer drilling technology, precise stimulation technology, and geology-engineering integration. Combining the internal and external environmental changes with the demands for oil and gas engineering “bottleneck” technologies, this paper comes up with the countermeasures for China’s oil and gas engineering “bottleneck” technologies development, namely focusing on the country’s key bottleneck technologies in the oil and gas engineering area and formulating the preferential policies and measures at the level of national strategy. It is necessary to increase exchange and cooperation with domestic and foreign institutions and solve the bottlenecks in China’s key oil and gas engineering technologies as soon as possible. Those countermeasures are of vital importance to improve oil and gas exploration and development and secure the country’s national energy supply.

Schemes and Practice of High-efficiency Deepwater Oilfield Development Duan Ruikai, Yang Baoquan, Gu Wenhuan, Yang Li, Zhang Yingchun, Chen Xiao 2019, 38(5): 48-56.  DOI: 10.3969/j.issn.1002-302x.2019.05.009 Abstract ( )   PDF (4038KB) ( )   Deepwater Oilfield development usually faces a number of bottlenecks, such as multiple reservoir grades, high uncertainties, high requirements on execution of the plan, and difficulties in dynamic adjustment. China is among the latecomers in terms of deepwater oilfield development. Therefore, the high-efficiency development schemes remain immature in the deepwater area. Based on the study and practice of overseas deepwater oilfield development, this paper focuses on three important areas -- producing degree of reservoirs, execution of development plans and production management -- and summarizes the schemes of high-efficiency deepwater oilfield development. The “stereo”producing scheme of reservoirs is mainly structured with unified planning, evaluation at various levels, and quantitative estimation, thus promoting effective transformation from resources to geological reserves and subsequent producing reserves. The execution scheme is based on a “chain” plan of “progressive evaluation -- start of production without any delay – maintenance of stable production”, bringing about a high-efficiency stage from construction to production and the measures to keep production stable. The “multi-point” production management scheme is centered on “balanced development -- differential optimization -- efficient operation” , laying a solid foundation for efficient development by means of tapping the potential, increasing the reserve and improving efficiency. Good results have been achieved in overseas deepwater blocks by adoption of this high-efficiency development scheme. It is helpful to China’s domestic deepwater oilfield development in the future.

Industrial Policies of Advanced Hydrogen Energy Countries and Enlightenment You Shuangjiao, Zhang Zhen, Zhou Ying, Du Guomin, Wan Hong, Xu Ping, Bao Liqing 2019, 38(5): 57-66.  DOI: 10.3969/j.issn.1002-302x.2019.05.010 Abstract ( )   PDF (3117KB) ( )   There have been ups and downs in technological development of global hydrogen energy industry since the year of 1965. Driven by three main dynamic forces of energy security, climate changes and technological progress, the advanced countries and regions like Japan, the United States, the European Union and the Republic of Korea formulated their hydrogen energy industrial policies according to their own actual conditions. Japan and the Republic of Korea also released the detailed development route maps, with the hydrogen energy industry guided by the clear-cut policies. The United States attached importance to technological development but had a poor stability for policy support. The European Union used hydrogen energy to bring about low-carbon energy transformation. The industrial policies and continual investment in research and development as well as financial subsidies have substantially stimulated technological development and industrialization of hydrogen energy and fuel battery technology. Currently, China’s hydrogen energy industrial policy is short of top design at the national level but the local governments have a great enthusiasm for hydrogen energy, leading to a development momentum from bottom up. It is proposed that China should borrow the experiences in formulation of the industrial policies from the advanced hydrogen energy countries, clearly define the position of hydrogen energy in the country’s energy system and subsidize the whole industrial chain. In addition, China should include hydrogen energy into the national energy management system with reference to the natural gas management pattern.
