摘要
Abstract
A sound shale gas reservoir evaluation system is important for guiding unconventional shale gas exploration and development.Based on conventional logging data from Wufeng-Longmaxi Formation in Zhaotong area,a geological evaluation model for key parameters of shale gas reservoirs is constructed.The compressibility of shale gas reservoir is calculated by the analytic hierarchy process(AHP),and the reser-voir engineering evaluation model based on the compressibility classification is established.Then,combined with geological evaluation and engineering evaluation,a comprehensive evaluation model of shale gas reser-voir is constructed,and the actual fracturing perforation data is used to verify and analyze.The results indi-cate that Class Ⅰ reservoirs with better evaluation have higher gas production.Adopting a segmented and clustered design for horizontal wells can improve fracturing productivity efficiency.The constructed reservoir comprehensive evaluation model can evaluate shale gas reservoirs,which provides a good reference for shale gas reservoirs exploration in Zhaotong area.关键词
