Optimization and Development Trend of China’s Petrochemical Industry Li Yujing, Chen Qingjun, Zhao Yunfeng 2017, 36(2): 1-7.  DOI: 10.3969/j.issn.1002-302x.2017.02.01 Abstract ( )   PDF (2037KB) ( )   China ranks on the forefront of the world for its total petrochemical industrial output. However, the industry as a whole remains nothing powerful. The oil refining sector faces a series of issues, such as structural surplus in productivity, further division of the trend for oil products, upgrading of oil products quality, and rapid development of replaceable fuels. Olefin industry faces a series of challenges, such as slowdown of consumption and demand growth rate, increasingly intense competition, and structural shortage. Xylene is currently in serious shortage. PX exporters have a say in the market to a larger extent. Currently, China has become the largest PTA producer in the world. Shortage of PX makes the profit of the whole industrial chain dependent on others, highlighting the risks of the industrial chain. China’s petrochemical industry needs to convert its growth pattern in next few years, upgrading itself into an industrial power from an industrial major. It is necessary to focus efforts on six areas – optimize layout and adhere to integrated development, optimize structure of olefin raw material and lower oil crude consumption growth for higher cost competitiveness, step up technological innovation and enhance conversion of catalytic diesel, develop high-end products and improve domestic market consumption level, accelerate elimination of outdated productivity and promote industrial upgrading, and appropriately deregulate export of oil products

Corporate Intellectual Property Management under New Situation Liu Yang, Wang Lu 2017, 36(2): 16-21.  DOI: 10.3969/j.issn.1002-302x.2017.02.03 Abstract ( )   PDF (1725KB) ( )   As the company’s precious assets, intellectual property (IP) should be brought under management, unified planning and development for higher value and profit. Different from tangible assets, intellectual property is clear in characteristic and diversified in risk. It needs a lot of efforts for maintenance and control as well as prevention of infringement. This article focuses on the IP risks the Chinese enterprises currently face in the areas of business, lawsuit, administration and law as well as competitors, strong patent pools, suppliers and clients. The related departments and enterprises should take active measures to guard against the risks. The enterprises should establish scientific IP management patterns and enhance ownership management, process management and quality management. It is necessary to make a unified plan for reasonable distribution of patents. Based on higher standardized and scientific management, intellectual property will serve as the country’s advantageous tool and the enterprises’ important wealth and business counter.

Traditional carbon steel pipe is unable to meet the demand for transmission of highcorrosion mediums. Adoption of good anti-corrosion non-metallic tubular is one of important methods to prevent corrosion, and is widely used in the areas of oil and gas gathering and transferring as well as water injection. This article analyzes the main types and characteristics of typical tubular products of non-metallic and composite materials used at oil and gas fields. It also compares them with traditional metallic pipes for economic property of full service period. Based on investigating China’s present conditions and latest foreign tend for using pipes of non-metallic and composite materials, the article focuses on the latest development and prospect for research and application of non-metallic and composite material pipes in China. Suggestions are made on the issues currently existing in application of non-metallic and composite material pipes at the oil and gas fields.

Analysis of China’s Oil Reserves Situation and Plans for Additional Reserves Bai Zhenrui, Zhang Kang 2017, 36(2): 41-48.  DOI: 10.3969/j.issn.1002-302x.2017.02.08 Abstract ( )   PDF (2057KB) ( )   Newly-added proven oil reserve is a general conception that may cause different interpretations or misunderstanding. This article makes elaboration of this conception. It analyzes the economically recoverable reserves in China’s incremental original oil in place (OOIP) proven in recent years, the decline of reserve grade reflected by changes in recovery factor, low producing degree of the proven economically recoverable reserves, and the declining remaining recoverable reserves and reserve-to-production ratio. The article points out that China faces a sterner situation for oil reserves than decline of oil production in 2016. It is noticed that China still had a large amount of economically recoverable reserves remaining non-producing even if the annual average oil price was $110 per barrel. The article also makes analysis of the upstream difficulties caused by low oil prices. Some issues are exposed because China failed to tighten control over the economic recoverability of reserves. Based on the new situation of oil prices, it comes up with the plans for China’s future oil exploration. They include investment necessary to secure additional reserves, aggressive momentum for strategic replacement to ensure a certain amount of preliminary exploration wells, emphasis on dynamic economic recoverability evaluation of proven reserves, and promotion of reform to lower production cost by means of technology.

Review Reduction of Production at Oilfields Tang Wei, Zhang Hujun, Wang Donghui, Feng Jinde 2017, 36(2): 49-52.  DOI: 10.3969/j.issn.1002-302x.2017.02.09 Abstract ( )   PDF (1562KB) ( )   Oil prices have been kept at low levels for more than two years since plunge of oil prices in the second half of 2014. Oil companies both inside and outside China adopted the measure for reduction of oil production. This article analyzes the causes and concrete methods for three large-scale reduction of production at CNPC oilfields in 1998, 2009 and 2016. It also analyzes the reduction measures and their impact on production targets in 2009 and 2016. Based on the variations in the company’s general related indexes, the positive stimulation from the reduction measures is not obvious on development targets, according to the article. However, expenditure for investment cost dramatically dropped by means of reducing production, cost and spending, exerting a great influence on economic performance. The effect of the reduction measures at the oilfields should be brought under objective analysis. In response to fluctuations of oil prices, oilfields should adopt the active measures for their production to maintain sustainable development.

Latest Development in US Cost-effective Development of Shale Oil under Background of Low Oil Prices Wang Tiankai, He Wenyuan, Yuan Yuyang, Xu Kun, Li Guohao, Li Feng, Wang Shihong, Lv Lei 2017, 36(2): 60-68.  DOI: 10.3969/j.issn.1002-302x.2017.02.11 Abstract ( )   PDF (3489KB) ( )   US shale oil production reached 226 million tons in 2015, accounting for more than 50 percent of the country’s total crude oil production. The main experience in successful development of shale oil in the United States is the good environment for policies, solid accumulation of technology and the advanced managerial model. Shale oil exploration and development cost has dropped significantly in the United States thanks to those factors. As compared to 2014, the breakeven point of US shale oil declined by $30.5 per barrel in average in 2015, bringing about cost-effective development under the environment of low oil prices. It is proposed that China should launch research projects of key technologies to focus on improvement of single-well production and productivity, create production organizational management on the basis of higher efficiency and cost-effectiveness, initiate flat project-system management model or specialized company model, and formulate more preferential policies to promote unconventional oil and gas development efficiency. These measures will create the conditions for large-scale shale oil development, bring about strategic supplementation of resources and lay a solid foundation for energy substitution and security.
