| 摘 要： | 吉林省松江盆地油气勘探程度很低。通过松江盆地下白垩统长财组和大砬子组的系统取样与多项地球化学指标测试,详细评价了该区烃源岩的有机质丰度、类型及成熟度等各项指标。初步得出:松江盆地面积虽小,但巨厚的下白垩统沉积盖层中,大砬子组二段烃源岩发育,有机质丰度高,类型较好,且主要处于成熟阶段,具有较好的生烃能力;区内长财组和大砬子组一段发育储集层和盖层,形成了以上生下储为主的有利生储盖组合条件,具有一定的油气勘探前景,是松辽盆地外围油气勘探的较有利目标区。

| Abstract: | Hydrocarbon exploration is on a low level in the Songjiang baisn,Jilin Province.Therefore,we assess organic material abundance,types,and as well maturity items in detail through systematic sampling and test of Changcai and Dalazi Formation in lower Cretaceous,Songjiang basin.A primary summary can be conclude as following: the source rock in the basin is somewhat small in size,however,the second member of the Dalazi Formation,occurred in the extremely thick lower Cretaceous,is the most abundant source rock interval in which organic material is very high content,relative better types,as well as mature level,and owes the better hydrocarbon-genetic potential.In addition,the reservoir and seal are also widely developed in the Changcai Formation and the first member of Dalazi Formation of this area,forming the downward migration dominated combined condition of hydrocarbon play,presents good hydrocarbon exploration perspective,and finally becomes one of the more preferable target area for hydrocarbon outside of Songliao basin. |
