Practice and Reflection of Important Development Experiments Liao Guangzhi, Wang Liangang, Wang Zhengmao 2019, 38(2): 1-10.  DOI: 10.3969/j.issn.1002-302x.2019.02.001 Abstract ( )   PDF (5256KB) ( )   In 2005, PetroChina kicked off an important development experiment plan for the purpose to bring about transformation of development pattern and seek strategic substitute technology. Currently, 50 on-the-site experiment projects have been executed in 14 oilfields. There are four viewpoints shaped in the tenacious efforts and practice of more than 10 years. First of all, important development experiment is a strategic trial project for oilfield development and the key link for transformation of technological research achievements into large-scale production power. It reflects the main development orientation of oilfield development technology. Secondly, project management over the full life cycle can assure high-quality and effective operation of the project and accelerate the industrialization process. Thirdly, the working conception of “success depends on details” is pursued in practice to strictly keep the experiment procedures and focus on the process management, with the rules and regulations established. The daily management is based on those rules and regulations. Fourthly, importance is attached to in-depth analysis of typical experiments and systematic summing up of oilfield development laws and oil-flooding mechanisms, making preparations for industrialization.A series of advanced technologies, with independent intellectual property rights, have been innovated and developed in the important development experiment projects. Some technologies have been brought under industrialization, such as super-low permeability oil reservoir development in Changqing Oilfield, ASP flooding in Daqing Oilfield, steam-assisted gravity drainage of super heavy oil and heavy oil fire drive in Liaohe Oilfield and Xinjiang Oilfield, and CO2-drive of Jilin Oilfield, with the annual oil production exceeding 1600×104t in 2018. Significant breakthroughs have been made in hypoxic air flooding, miscible displacement of natural gas and binary compound flooding for middle and low permeable oil reservoirs. Those technologies are hopeful to be industrialized in the 14th Five-year Plan Period. The annual production is estimated to be kept at 2000×104t, making new contributions for acceleration of the company’s upstream business development.

Energy Industrial Development Trend from Angle of 2019 CERAWeek Liu Chaoquan, Lu Ruquan, Yang Zhaoming, Xu Dong, Gong Jinshuang, Peng Yun, Kang Yu 2019, 38(2): 11-16.  DOI: 10.3969/j.issn.1002-302x.2019.02.002 Abstract ( )   PDF (2175KB) ( )   The 2019 CERAWeek discussed the state and future trends of energy industrial development. It is reflected that energy geopolitics takes on the new characteristics and becomes an important force to reshape the global energy and even world trade structure as the United States is independent in energy supply and a net energy exporter in the future. Currently, the transition from fossil energy to renewable energy and from high-carbon energy to low-carbon energy has become the common awareness of international communities and the orientation pursued by international petroleum companies. Traditional fossil energy will remain dominant on long-term basis while natural gas is an important “transitional energy” to fuel future energy transformation. There is a diversity in the strategic options made by various oil companies. Technological innovation and digital development hold the key to energy transformation. Under the new situation, US shale oil production, OPEC+ and oil demand growth are the three key factors to determine global oil market. The study points out that China’s oil and gas industry should make an active response to the future energy development changes in the areas of innovation-driven development, acceleration of natural gas development business and distribution of new energy.

However, development in this area remains unsatisfied because energy construction on the route is affected by political situation, economic level and bottlenecks of fund and technology. The PPP model, which is based on the public-private partnerships, will be introduced into international energy cooperation in the countries on the route to promote their energy construction and enhance China’s multilateral international energy cooperation. This paper makes briefings about the current research and cooperation situation of the energy PPP model both inside and outside China and analyzes the main participants and their complication relations in international energy PPP cooperation against the “One Belt One Road” background. Five typical “One Belt One Road” international energy PPP projects, located in Myanmar, Cambodia, Pakistan and Bangladesh, are brought under study. A number of designing schemes are put forward for the model, such as selecting the PPP operational model according to properties of projects and classification of introduced elements, the mechanism for distribution of the project’s basic and abnormal returns, the risk-sharing framework with the process mechanism and dispute-handling procedures, the dispute-settling platform and the dispute-handling system composed of multilevel dispute-settling sub-systems. To ensure effective execution of the energy PPP cooperation projects, the concrete proposals are made in top design at the national level and improvement of the capacity for involvement of social capital into international projects.

More efforts are focused on horizontal well development on the basis of technology. The horizontal well productivity is constructed in the pattern of “deployment in clusters, differential design and process-oriented practice”, with drilling industrialization, device skidding, and process improved in innovation. The gas production of a single horizontal well is (4.5-5.0) ×104m3/d in the previous three years, 4.7 times as high as the production of a single straight well. The accumulated gas production of the horizontal well is four times as high as that of a straight well.As compared to the previous development pattern, the land area of 13.3 km2 is cumulatively saved while the drilling period is shortened for 8686 days, making drilling service high-quality and cost-effective and using less wells for a high yield. The efforts are focused on fine management and establishment of the steering-while-drilling process. The digitalized oil and gas reservoir research platform and decision-making support system are fully used to improve probability of penetration. The average probability of penetrating sand body is raised to 78 percent while the average probability of penetrating gas horizons is boosted to 62 percent. Supervision is strengthened to assure the quality of project with the efforts to promote green development of gas fields on the basis of clean process. Based on innovation of integration of mindset, technology and management as well as integration of the key technologies for compact sandstone gas reservoir, the internal earnings rate approaches 20 percent, bringing about a large-scale and cost-effective development of the Sudongnan block.

Analysis of Technologically-driven Cost-effectiveness Cases from Oil Companies An Qi’er, Zhang Hujun, Qu Debin 2019, 38(2): 57-63.  DOI: 10.3969/j.issn.1002-302x.2019.02.009 Abstract ( )   PDF (2873KB) ( )   The Chinese and foreign oil companies have taken a series of measures for cost-effectiveness since the slump of oil prices. Of those, technological modernization has a long-term and remarkable effect on cost-effectiveness. An investigation was made on management methods and achievements of technology. This article summarizes the technology-based costeffectiveness methods in the six areas. International oil companies have attached great importance to investment for technology and enjoyed high returns from technological investment. Shell Technology Ventures was launched in an attempt to keep its ability to discover and convert the latest industrial technology. Development of compact oil and shale oil was concentrated in the specific areas and on a large scale, with the key superiority established. To reduce the cost on a long-term basis, the efforts should be devoted to reduction of the structural cost, instead of the periodic cost rising with resumption of the industry. Digitalization is an engine for technological innovations in the oil and gas industry. The development path designed by BP for digitalization is worth being borrowed. The objective for cost management is to optimize the cost, instead of minimizing the cost. For example, the drilling cost for each barrel of oil can more effectively reflect overall economic performance than the drilling cost of a single well.
