摘要(Abstract)：

页岩油气革命改变着世界能源格局,成为全球石油行业的研究热点。通过对松辽盆地青山口组与国内外含页岩油层系地质特征对比可知,古龙页岩油与国内外海相或咸化湖盆沉积为主的页岩油在岩石组构、物性、含油性、流动性方面有很大差别:古龙页岩有机质丰度高,含油性好;矿物纹层和页理非常发育,储集空间类型多样,储集性较好;热演化程度较高,气油比较高,地层超压,油质轻且黏度小,易于流动;黏土矿物含量高、碳酸盐含量低,但黏土矿物以伊利石为主,储层水敏低,仍然表现出较强的可压性。古龙页岩油地质条件优越、资源量巨大,具有广阔的勘探开发前景。向古龙页岩油进军,是大庆油田面向未来作出的战略抉择,对保障国家能源战略安全、推进中国石油建设综合性国际能源公司和促进区域经济社会发展具有战略意义。古龙页岩油的规模效益开发,必须突出科技创新的引领作用和管理创新的保障作用。
Shale oil and gas revolutions have changed the framework and pattern of the world energies, and moreover the shale oil and gas have become the research hotspot of the global petroleum industry. The comparisons of the geological characteristics between Qingshankou Formation in Songliao Basin and other shale oil reservior series at home and abroad show that there are a large differences in the rock composition, physical property, oil-bearing property and flowability between Gulong shale oil and other shale oils which are mainly marine or saline lacustrine lake deposit.Gulong shale oil is characterized by pretty higher organic matter abundance and much better oil-bearing property; well-developed mineral lamina and foliation, various types of accumulating space and much better reservior property; pretty higher degree of the thermal evolution, much higher gas-oil ratio, formation over pressure,lighter oil and smaller viscosity, and ease to flow; rather higher clay mineral content and rather lower carbonate content, but the clay minerals are mainly illite with pretty lower water sensitivity, and still show much stronger compressibility. Gulong shale oil has superior geological conditions and huge resources, and shows a broad prospect of exploration and development. The march towards Gulong shale oil is the strategic choice made by Daqing Oilfield for the future, which is of strategic significances to ensure the national energy strategic security,accelerate the construction of CNPC into a comprehensive international energy company and promote the development of the regional economy and society. The large-scale benefit development of Gulong shale oil must highlight the guiding and leading roles of the scientific-technological innovations and the supporting role of management innovations.
