摘要
文96地下储气库是典型的枯竭气藏型地下储气库,通过对文96地下储气库运行连通性、动态库容、边水变化、单井注采能力等的深入分析,总结了边水气藏改建地下储气库的运行规律和动态特征,文96地下储气库投产后运行实践证实储气库平面连通,注采井注采能力达到设计要求,地面配套注采工艺系统运行效果良好,通过高部位强注、低部位缓注、合理控制生产压差等措施于注采气期间较好地控制了边水运移,达到了排液扩容的目的,库容逐步接近设计的库容量。
Wen 96 underground gas storage is a typical depleted gas reservoir. Both operation rules and dynamic features of this storage rebuilt from an edge-water gas reservoir are summarized in terms of connectivity, dynamic tank capacity, edge-water change,and single-well injection-production capability. From the point of its operation, this storage is laterally connected, and its injectionproduction capability meets the designed demand, and the matched injection-production system is in good order. In addition, in order to expulse liquid and enlarge capacity, some countermeasures are made to control edge-water migration during injection and production, such as strong injection at the higher part, slow injection at the lower part, and reasonably control the difference of operation pressure. Actual tank capacity approximates to the designed one.
