大庆长垣南部地区浅层气成因类型及富集规律研究

摘要

对大庆长垣南部地区黑帝庙油层天然气地球化学分析的基础上,结合有机质的热演化规律和前人的天然气分类标准,认为黑帝庙油层天然气为生物气和油型气两种成因类型.综合松辽盆地构造演化特征、断层活动规律、砂体分布规律和圈闭类型分析,认为黑帝庙油层天然气的富集主要受源断裂和圈闭类型控制.由源断裂控制的断背斜圈闭是天然气富集的有利场所.%On the basis of geochemical analysis to natural gas of Heidimiao oil layers in the south of Daqing placanticline, combined with the thermal evolution rule of organic matter and previous classification of natural gas, and natural gas of Heidimiao oil layer mainly contains two genetic types, that are biogas and oil type gas. Synthesized the tectonic evolution features, fault active rules, sand distribution rule and trap types' analysis of Songliao Basin,the enriching of natural gas of Heidimiao oil layer is mainly controlled by source faults and trap types. The fault anticline trap, which is controlled by source fault, is the favorable for natural gas accumulation.
