| Abstract: | In the exploration area of marine sedimentary sequences,two sets of good source-reservoir-cap assemblages develop under Middle Cambrian Qinjiamiao subsalt strata.By analysis of the subsalt characteristics and distribution of the source rocks,reservoirs and cap rocks,it is indicated that the Upper Sinian Doushantuo shale and Lower Cambrian Shuijingtuo shale are good source rocks,and the Upper Sinian Dengying carbonate rock and Lower Cambrian Shilongdong carbonate rock can provide good reservoir conditions.Th... |
