摘　　要：钻注采井是建设枯竭油气藏储气库的重要环节。在建设大张坨储气库时 ,大港钻采工艺研究院对枯竭油气藏地下储气库注采井的钻井工程进行了详细研究 ,形成了该类储气库注采井的钻井技术 ,并对大张坨、板876、板中北高点地下储气库进行了钻井工程设计。从完井测试及注采生产情况来看 ,应用效果较好 ,基本能够满足储气库建设的要求。文章以大张坨储气库为例 ,从井口布置及井眼轨道优化、井身结构设计、套管柱设计、套管柱设计、固井设计、钻井液体系和储层保护设计、重点施工措施以及钻探效果等方面阐述了利用枯竭油气藏建地下储气库的钻井技术。When building Dazhangtuo gas storage, Dagang Drilling and Production Technology Research Insti tute studied the drilling engineering of injection and recovery wells for depleted reservoirs in detail, and developed the drilling technology of injection and recovery wells for this kind of gas storages. Also, The Institute made the drilling engineering designs for the underground gas storages of Dazhangtuo, Ban876, and Ban north central high. From the situation of well-completion test and injection and recovery operation, the results are good. The requirements to build gas storages can be met essentially. Taking Dazhangtuo gas storage as example, the article describes the drilling technol ogy to build underground gas storages with depleted reser voirs on well-head arrangement, optimization of borehole trajectory, well profile design, casing string design, cemen ting design, design for drilling fluid system and reservoir protection, major working measures and drilling results, etc.
