摘要
根据前人研究成果,结合煤田地质基本情况,分析了构造因素对河东煤田中南部煤层气富集的控制影响,认为研究区在构造类型上属于构造形迹微弱的过渡性盆地边缘,构造史控制下的埋藏史和热演化史对本区煤层气的富集有着重大意义,现今井田构造的贡献意义不大。进一步综合各方面因素,确定了区内两个煤层气勘探开发有利区域。
Gas accumulation under control of tectonic factors was analysed based on previous works and basic geologic situation of center and the south of Hedong coalfield. It was considered that research area could be assorted to transitional basin margin by structure type, which had week tectonism. Burial and metamorphism history controlled by tectonic history devoted much to gas accumulation, while present structures of coalfield devoted little. Two areas were pointed out for exploration after considering all factors.
