The Policy Suggestions for Stable Production of Domestic Maturing Oilfields and Economic Development of Low-grade Oilfields Qu Debin, Zhang Hujun, Li Feng, Bai Xijun, Wang Xiaolin 2015, 34(6): 1-5.  DOI: 10.3969/j.issn.1002-302x.2015.06.001 Abstract ( )   PDF (1708KB) ( )   Currently, most of the proven oil reserves in China are low-graded with the rise of development cost. The main developed oilfields entered their late development period with the continual rise of water cut and development cost. Meanwhile, a variety of charges and taxation narrows the profit-making space of the Chinese oil companies’ upstream business, making the economic performance drop rapidly. Based on analysis of main oil and gas fields, this paper proposes that the State should adopt eight preferential policies in favor of oil companies, such as eliminating the windfall tax, reducing the royalties for resources, using appropriate amount of capital to offset taxes, continuing to launch special fund for technological research, supporting production of low-yield and low-efficiency wells as well as effective development of compact gas, and encouraging recovery from tailing resources. The efforts should be strengthened to tap the potential for development of the remaining marginal reserves during the late recovery period of old oilfields. Meanwhile, the low-graded reserves should be also brought under effective development on a large scale so as to bring about a sustainable development situation with both state revenue and enterprises’ performance increased, enlarging the basis of reserves to keep China’s crude output stable and rising at an appropriate rate.

Present Conditions and Technological Demand of Oil and Gas Exploration and Development in China’s Eastern Faulted Basins Qin Weijun, Zhang Zhonghua 2015, 34(6): 42-45.  DOI: 10.3969/j.issn.1002-302x.2015.06.009 Abstract ( )   PDF (1536KB) ( )   The targets to be found in China’s eastern faulted basins of the Paleogene System-the Neogene System become more and more subtle. With the main oil reservoirs entering their “three high” stage, it is more and more difficult for exploration and development. However, the reserves are still regarded as tremendous. It is of great significance to analyze and study future technological development. The low-graded and subtle oil and gas reservoirs in this region will be the main targets for future exploration and development. It is necessary to update the knowledge about continental source strata and accumulation efficiency, focus the study on spatial differential distribution of remaining oil and gas resources, continue to develop and perfect the trap and reservoir description and prediction technology which is dominated by 3D seismic exploration technology, and develop the wellbore technology aimed at improving single-well productivity, such as large-displacement, multi-target, horizontal well drilling technology as well as staged fracturing and volumetric fracturing technologies. It is also necessary to develop the fine exploration and development technology for marginal oil and gas reservoirs, complex geological bodies and improve the EOR technology for high and ultra-high water-cut oilfields, promoting high-efficiency development and utilization of complex and low-grade oil and gas resources.

Exploration Potential and Targets of Jurassic System in Central Sichuan Han Keyou, Wang Yujun, Zha Quanheng 2015, 34(6): 51-57.  DOI: 10.3969/j.issn.1002-302x.2015.06.011 Abstract ( )   PDF (2699KB) ( )   The oil area of the Jurassic System in Central Sichuan is regarded as poor mine because no breakthroughs were made in exploration of the area in the past five decades. The main reservoirs are the early confirmed shell limestone of 1st and 3rd interval of Da’anzhai Section (with the porosity being less than 1%). They are identified as fractured oil fields with the geological resources amounting to 11×108t. Later, the reservoirs of muddy shell limestone were found in the area (with the porosity being 1.56%). With the exploration potential boosted, the resources in the area rose to 35×108t. The present study indicates that the average porosity of source strata – 2nd interval of Da’anzhai Section mud shale subzone – is 2.35% while the average porosity of mud shale containing organic matter is 3.8%. Oil and gas were found in drilling. They are the main reservoirs in the area with many high-yield wells drilled. Therefore, the Jurassic System in Central Sichuan is regarded as locally sourced and accumulated shale oilfields. In the semi-deep lacustrine zone of 26000 square kilometers in Central Sichuan, the thickness of mud shale is higher than 40 meters while TOC is 1.5-2%. It is the favorable zone for exploration of shale oil. Based on the volumetric method, the geological resources of shale oil from Jurassic Da’anzhai Section and Lianggaoshan Formation are 164×108t. It is proposed that source strata of Jurassic mud shale should be further studied, establishing an experiment zone of shale oil development in Central Sichuan. Da’anzhai Section of Gongshanmiao and Guihua oilfields as well as Lianggaoshan Formation of Nanchong Structure can be selected for pilot development of shale oil, accelerating the exploration process in this field.
