摘　　要：通过大庆长垣南部黑帝庙油层天然气显示井与其成藏条件之间的时空分布关系,对其成藏主控因素及时空匹配关系进行了研究,得到源断裂、盖层和圈闭是其天然气成藏的主控因素.源断裂破坏了H61,H51,H41小层3套区域分布的泥岩盖层,使其封闭能力变差,3种类型圈闭均分布在源断裂上或附近.明水组沉积末期3个主控因素匹配关系较好.通过3个主控因素与天然气显示井之间时空分布关系研究得到,大庆长垣南部黑帝庙油层天然气聚集层位和平面分布部位主要受源断裂、盖层和圈闭空间匹配关系的控制.明水组沉积末期3个主控因素时间上的较好匹配有利于天然气在黑帝庙油层富集成藏.According to the time-space distribution relations between gas displaying wells of H oil layer in the south of Daqing placanticline and their accumulation conditions, the main controlling factors for oil and gas accumulation and time-space matching relations were studied. It was considered that the fault connected sourcerock and reservoir, cap rocks and traps were main controlling factors for gas accumulation. We find that fault connected sourcerock and reservoir damaged 3 sets of regional mudstone cap rocks, they made the sealing capacity poorer and 3 types of traps distributed near the fault connected sourcerock and reservoir of H oil layer in the south of Daqing placanticline, matching relation 3 main controlling factors in the end of K2m was better. By the research on the relation between time-space distribution of 3 main controlling factors and gas displaying wells, it was concluded that gas accumulation horizons in H oil layer in the south of Daqing placanticline and distribution positions in the plane were mainly controlled by time-space distribution relations among fault connected sourcerock and reservoir, cap rocks and traps. In the end of K2m sedimentary period, better matching of 3 main controlling factors in time domain was favorable for the accumulation of gas in H oil layer.
