Suggestions on Sustainable Development of CNPC’s Engineering Technological Service Business Liu Xinghe, Liu Bingyi, Zhu Jingping, Cong Qiang 2015, 34(3): 1-5.  DOI: 10.3969/j.issn.1002-302x.2015.03.001 Abstract ( )   PDF (3138KB) ( )   China National Petroleum Corporation (CNPC) has actively opened up the engineering technological service market both at home and abroad since it restructured its specialized companies in 2007. With implementation of the creation-driving strategy, CNPC has significantly improved its market competitiveness, providing powerful support for oil and gas exploration and development. The profit of domestic business rose to 960 million yuan in 2013 from a loss of 1.9 billion yuan in 2008. The overseas profit has been kept at about 1.9 billion yuan since 2008. However, there are some issues existing in the business development process, such as inadequate business turnover, weak profit-making capacity, unreasonable assets structure, shortage of high-end technology and equipment, slow development of key technology, imbalance of internal market price, and inadequate capacity for expansion of international market. Those problems resulted from imperfect design at top level, unclear strategic positioning, and outdated human resources management pattern in the specialized restructuring process. Therefore, it is suggested that CNPC should clarify its positioning and target for its engineering technological service business development, establish and perfect the internal price system based on quota and market price, provide the fair, just and open platform for talents development, tighten control over market admission qualification, perfect regional market coordination mechanism, step up research and development of key technology and high-end technology with creation of technological management, and invigorate development of engineering technological service business.

The key facility is 50kg/h gas phase full density polyethylene pilot plant, which can be used to produce polyethylene products in a full range of density by means of titanium, chromium and metallocene and other catalysts. The catalyst feeding system is creatively designed for the plant that adopts eight items of dedicated technology including a catalyst powder trace precise feeding technology. A technological committee was established in operation and management of this creation platform to test the “process and safety integration” management pattern and long-term cooperative and exchange mechanism. As an important integral part of CNPC’s oil refining technological creation system, the platform accelerated development process of the key projects and conversion of independent research results and played an active role in improvement of polyethylene production technology. Up to now, a total of 11 research projects have been brought under study, providing support for seven projects in their industrial application. Appraisal of eight catalysts in four categories of Z-N, metallocene, chromium and titanium-chromium composites was completed at the same time. A total of 15 new products have been developed, such as special material for auto fuel tank, creating more than 50 million yuan of economic results.

Performance Evaluation and Adjustment of Oilfield’s Strategic Development Targets Zhai Jinsheng, Yang Guang, Zhai Hongcui, Liu Jianwu 2015, 34(3): 22-29.  DOI: 10.3969/j.issn.1002-302x.2015.03.005 Abstract ( )   PDF (4850KB) ( )   The important work for management of corporate strategy is to make timely strategic assessment and adjustment in line with changes in the company’s external environment and internal structure. Based on the related evaluation theories and combined with actual management of the company’s strategy, the strategy-assessing system of PetroChina Huabei Oilfield Company adopts the quantitative and qualitative pattern to make comprehensive assessment of the company’s strategy in three areas – environmental analysis, evaluation of target-realizing extents and evaluation of business development. This system selects four factors of general amount, structure, performance and efficiency as the targets for the level of standards and then determines the weight of each concrete index, establishing the assessment standards for calculation of realization extents of the annual strategy. Practices indicate that evaluation of strategy plays an active role in promoting the company’s sustainable development and helps adjust its development strategy.

Prospect of Offshore Managed Pressure Drilling Technology Zhai Xiaoqiang, Wang Jinlei, Li Pengfei, Huang Zhe, Wen Xiaosong 2015, 34(3): 56-60.  DOI: 10.3969/j.issn.1002-302x.2015.03.012 Abstract ( )   PDF (3181KB) ( )   Offshore oil and gas exploration and development are extending into deepwater areas. The downhole complicated troubles in deepwater drilling service, such as kicks, leakages, sticking and collapse, become major bottlenecks for deepwater oil and gas exploration and development. Therefore, offshore managed pressure drilling (MPD) technology is extensively adopted abroad to solve such problems as drilling in narrow density window, operation on oceanic surface, gas kick in drilling risers, prevention of drilling accidents, protection of reservoirs, and reduction of operational time and service cost. This paper introduces the characteristics and application of four main technologies, such as constant pressure and managed pressure drilling technology, slurry cap drilling technology, dual-gradient drilling technology and HSE pressure-controlled drilling technology. It also analyzes the current problems existing in domestic development of offshore MPD technology and points out the future research efforts should be focused on applicability, equipment and process of offshore MPD technology.

Clarification and Analysis of Petroleum Resources-Reserves-Production Term Series Zhang Kang, Lu Quanjie 2015, 34(3): 61-67.  DOI: 10.3969/j.issn.1002-302x.2015.03.013 Abstract ( )   PDF (4141KB) ( )   Petroleum resources, reserves and petroleum are the most basic parameters in the upstream sector of petroleum industry, forming a series of complicated terminologies. However, some misunderstanding and errors exist in application of this series of terminologies in real production practice. It is necessary to make clarification of those terminologies. This paper points out the differences in conceptions under the difference circumstances both inside and outside China. It helps readers how to understand and use those terminologies under the market economy to better reflect the real conditions. The paper also discusses a series of other issues, such as poor quality of newly-added reserves in China, putting a large quantity of undeveloped reserves into production, unified measurement of natural gas fuels, and commercialization rate of oil and gas production.

Impact of Low Oil Price on Tight Oil Development Zhang Huanzhi, He Yanqing, Qiu Maoxin, Wang Lu 2015, 34(3): 68-70.  DOI: 10.3969/j.issn.1002-302x.2015.03.014 Abstract ( )   PDF (2236KB) ( )   Economically-effective development of non-conventional oil and gas has led to significant changes in global oil and gas supply since the start of the 21st century. Particularly, tight oil production has risen rapidly in North America. However, recent low oil price has caused concerns over cost-bearing capacity and development of tight oil. The study indicates that tight oil production in the United States will not substantially drop in a short term in despite influence of low oil price. Producers have taken relative measures to control and lower production cost while increasing the output to maintain the profit. The concrete measures include reduction of investment and in-service rigs, optimization of assets portfolio, concentration of investment and rigs on the “key areas,” improvement of capital operation efficiency on the basis of technological progress, and use of partial rigs for production of shale gas instead of tight oil. Based on those efforts to meet the challenges, domestic oil companies are proposed to strengthen technological creation andcooperate with their foreign counterparts for tight oil exploration and development.
