辽河油区储气库水平井钻井与固井技术

辽河油区地质条件复杂,针对复杂断块油气藏改建地下储气库面临的技术挑战有两方面:一方面东部断陷盆地形成复杂破碎的断块构造加上储层复杂多变的陆相河流相沉积,建库存在较大的难度;另一方面辽河油区储气库井固井技术还不完善。解决的措施主要包括与建设方合作完成储气库建库评价设计与运行技术,采用水平井、分枝井钻完井技术完成储气库钻井工程。

Horizontal Drilling and Cementing Technology of The Gas Storage In LiaoHe Oil field

The geological conditions are complex in LiaoHe oil field,there are two technical challenges for Complex fault-block reservoir convert underground gas storage: First,east rift basin form a complex broken structure with reservoir deposited by complex continental rivers,it is very difficult to build the stock;Second,the gas storage well cementing technology in LiaoHe oil region is not perfect.Face these challenges,the measures include collaboration with construction side to build gas storage evaluation design and operation technology,collaboration with professional oil companies,use horizontal wells,branch well drilling and completion technology to complete gas storage drilling.
