| 摘 要： | 大庆长垣南部浅层气主要为来源于嫩江组一二段的生物气,混入少量的青山口组热成因气和无机成因CO2.明水组沉积木期为嫩江组一二段大量生排生物气时期,此时断裂活动导致黑帝庙油层背斜和断圈的形成,并诱导生物气垂向运移,"三期复合"使大量生物气向黑帝庙油层运移.活动断层均为"断裂密集带"的边界断层,沿其垂向运移的生物气聚集的部位...

| Abstract: | Shallow gas in the south of Daqing placanticline is mainly biogas originated from K1n1+2,mixed with a small amount of thermogenic gas of K1qn and inorganic CO2. The main biogas generation and expulsion period of K1n1+2 is the end of K2m sedimentary period,when fault activities caused the formation of anticline and fault trap of Heidimiao oil layer and induced vertical migration of biogas. The composite of the three periods made large amount of biogas migrate into Heidimiao oil layer. Active faults are all b... |
