Key evaluation techniques in the process of gas reservoir being converted into underground gas storage
摘要
Abstract
Due to the significant differences in development modes and operation rules of underground gas storage (UGS) and gas reservoir,the design of UGS construction has its own particularity and complexity.Key evaluation techniques in the process of gas reservoir being converted into underground gas storage were proposed and field application was analyzed.The construction and operation experience of the first batch commercial UGS in China was summarized,the mechanisms of multi-cycle injection and production with large flux in short-term was examined and some concepts were proposed such as the dynamic sealing of traps,the effective pore volume of UGS and the high velocity unstable seepage flow with finite supply.Four key technologies of UGS,i.e.,trap sealing evaluation,gas storage parameter design,well pattern optimization and monitoring programs design were created.Preservation condition,storage capacity,effective injection & production and safe operation technology problems of UGS were solved respectively.The geological program design technology system of UGS construction in a gas field was gradually enriched and improved.These technologies have successfully guided geological plan design and implementation of UGS construction in a gas reservoir,the effects of dilatancy and production were great,and the actual dynamic was very consistent with design indicators.关键词
