从华北上古生界煤层分布。以及煤成气、煤层气分布入手,分别对生、储、盖、圈闭、埋藏史等成藏条件进行了分析评价。结合对苏桥—文安气田的解剖,具体分析了该区煤成气富集成藏的控制因素并总结出两大类成藏模式。指出:苏桥—文安、黄骅南部为最有利煤成气勘探区;沁水盆地北部、临清坳陷、东濮凹陷北部和周口坳陷为煤成气较有利勘探区;孔店构造带和乌马营构造带为最有利勘探目标;沁水、柳林、大城、两淮、豫西—豫东等地区煤层气勘探开发前景较好,以沁水为最佳。
Upper Paleozoic coal seam distribution from North China. As well as the distribution of coal gas and CBM. The conditions for hydrocarbon accumulation such as genesis, storage, cap, traps and burial history were analyzed and evaluated respectively. Combining with the anatomy of the Suqiao-Wen’an gas field, the controlling factors for enrichment and accumulation of coal gas in this area are analyzed in detail, and two types of reservoir forming patterns are summarized. It is pointed out that Suqiao-Wen’an and Huanghua are the most favorable coal-formed gas exploration areas; northern Qinshui Basin, Linqing Depression, northern Dongpu Depression and Zhoukou Depression are the favorable exploration areas for coal-formed gas; Wumaying tectonic belt is the most favorable prospecting target; Qinshui, Liulin, Dacheng, Lianghuai, Western Henan - Yudong and other regions have good prospects for CBM exploration and Qinshui is the best.
