摘要: 针对陆相页岩油储层特点及勘探开发需求，中国石化围绕陆相页岩油优快钻井完井技术、测井录井评价技术和储层改造技术等进行攻关研究，并完成了17口探井，有力支撑了济阳坳陷、泌阳凹陷和四川盆地等区域的陆相页岩油勘探开发评价，济阳坳陷页岩油勘探取得了重大突破。与国外页岩油工程技术相比，中国石化页岩油工程技术仍存在较大差距，为此，还需要进行页岩油井工厂多层系立体开发技术、超长水平段水平井钻井关键技术和页岩油地质–压裂一体化技术攻关，以形成完善的页岩油工程技术体系，以满足提质提速提效提产的需求，实现陆相页岩油的效益开发。Abstract: Depending on the characteristics and the demands of exploration and development of continental shale oil reservoirs, Sinopec has carried out researches on technologies for such reservoirs, including optimized and fast drilling and completion, logging evaluation, and reservoir stimulation, etc. These new technologies, which have been successfully applied to 17 exploratory wells, strongly support the exploration and development evaluation of continental shale oil in a number of regions, such as Jiyang Depression, Biyang Sag, and Sichuan Basin,etc. And with them, a major breakthrough was achieved in the exploration of shale oil in Jiyang Depression. However, the shale oil engineering technologies of Sinopec still lag behind those of some foreign countries. Therefore, further research is still needed in technologies of multi-layer stereoscopic development by shale oil well factory, drilling of horizontal wells with ultra-long horizontal sections, and integration of shale oil geology and hydraulic fracturing. Sinopec’s research could thereby strive toward the perfection of the shale oil engineering technology system, the improvements in quality, speed, efficiency, and output, and the beneficial development of continental shale oil.
