| 摘 要： | 通过对松辽盆地西部斜坡带400余口井的回剥分析,再现了油气运移关键时刻区域盖层的底界面构造。从该构造图上识别出油气向西部斜坡带运移的4种脊状构造,即鞍状构造-岩性脊、断层-岩性脊、背斜-岩性脊和纯岩性脊。4种脊状构造在空间上的有机组合形成了油气向松辽盆地西部斜坡带运移的主输导通道。该主输导通道呈枝状,先从多个方向汇集了来自齐家-古龙凹陷的油气资源,然后向两个主要方向输送,其一向北西方向的富拉尔基,其二向西部的平洋油田方向。

| Abstract: | Analyses of data acquired in over 400 wells have reproduced the structures on the bottom boundary of regional caprock (Nenjiang Formation) in the critical period of hydrocarbon migration. Four kinds of ridge like structures, saddle structural lithological ridge, fault lithological ridge, anticlinal lithological ridge and lithological ridge, can be identified from the structural map. The spacial array of these ridge like structures acted as the major hydrocarbon migration pathway system to the western slope zone of Songliao basin. Hydrocarbons from Qijia Gulong depression would be gathered through this major brancing pathway system, and then migrated northeastward to Fulaerji and westward to Pingyang oilfield,respectively. |
