砂岩枯竭型气藏改建地下储气库方案设计配套技术

Project design and matching technologies for underground gas storage based on a depleted sandstone gas reservoir

我国地下储气库建设尽管发展迅猛,但水平仍处于起步阶段,较为成熟实用的地下储气库设计技术与方法尚不多见。为此,总结了中国石油大港油田公司利用砂岩枯竭型气藏改建6座地下储气库的地质方案设计配套技术。该技术创新了大型地下储气库地质方案设计方案,明确了方案设计应遵循的主要程序及主体内容,创建了7项行之有效的配套设计技术,提出了26项气库评价与运行指标,形成了较为系统的方案设计模式与技术系列,对我国正在火热推进的地下储气库建设工作具有指导和借鉴意义。

Underground gas storage are developing rapidly in China but the related technologies are just getting started,so neither known methods nor practical technologies could be easily found then for this project design.Therefore,based on a summary of the successful experiences from 6 cases of underground gas storage rebuilt on sandstone gas reservoirs by the PetroChina Dagang Oilfield Company,the geology project design and matching technologies are concluded as follows:First,it is clearly described what main procedures and contents this improved geology project design for large underground gas storage should follow and include.Second,7 items of practical matching technologies are summarized.Third,26 indicators of gas storage evaluation and operation are presented herein.Thus,the systematic project design mode and technology series are formed,being of guidance and reference for the construction of underground gas storage in China.
