近期在琼东南盆地东部获得S34含气区优质煤型气发现。研究认为S34含气区被(6)号断裂分割成不同构造圈闭、气水系统、天然气成熟度和来源的气藏。S34含气区的发现首次证实了松东、松南凹陷煤型气含气系统,其中S27、S28和L4区、深水Y8区发育一批有利目标,开拓了琼东南盆地煤型气勘探新领域。
Recent discovery of high quality coal gas in S34 gas district in the eastern part of Qiongdongnan basin. The study shows that the gas zone in S34 is divided into gas reservoirs with different structural traps, gas and water systems, natural gas maturity and source by the fault number (6). The discovery of gas zone in S34 has for the first time confirmed the coal-gas type gas systems in Songdong and Songnan sags, and a number of favorable targets have been developed in S27, S28 and L4 zones and Y8 zone in deep water, opening up new areas for exploration of coal gas in Qiongdongnan Basin.
