中文摘要:松辽盆地南部青山口组一段发育一套半深湖相沉积的暗色泥页岩,有机碳含量高,偏腐泥型有机质,热演化程度适中,老井复查存在大量的泥页岩含油气异常,测井响应特征明显,是页岩气研究的有利层位。在对储层基础地质条件研究基础上,运用地球物理、测井和现场解析等手段全方位分析了泥页岩的含气性和平面展布特征。对青山口组一段进行了有利区预测和资源计算,显示本区具有丰富的页岩气资源潜力,满足陆相页岩气选区含气量要求,是有望取得页岩气勘探进一步突破的有利靶区。

Continental shale gas-bearing analysis and exploration prospect: a case study from K1q1 formation of southern Songliao basin
Abstract:In the southern Songliao basin, a set of dark mud shale with semi-deep lacustrine sediments was found in the K1q1 formation, where the organic matter is rich and the partial sapropelic organic matter has a moderate degree of thermal evolution. There are a large number of mud shale hydrocarbon anomalies, and the logging response is obvious and it is a favorable formation for shale gas study. Based on the research on the basic geological conditions of reservoirs, the gas-bearing and plane distribution characteristics of shale are comprehensively analyzed by means of geophysical, well logging and desorption experiments. The favorable section prediction and resource calculation for the K1q1 formation show that the region has rich potential of shale gas resources and meets the requirement of gas content in the continental shale gas formation and is a favorable target area for further breakthrough in shale gas exploration.
