| 摘 要： | 松辽盆地西部斜坡为倾缓的单斜,自东而西可划分为两个带:泰康—富裕缓坡构造带和泰来—甘南超覆带,自下而上的沉积分为断陷构造层、坳陷构造层和反转构造层,3个构造层的原地烃源岩均不能大量生烃。坳陷层青山口组—嫩江组一-二段有来自齐家—古龙凹陷的油气,为西部斜坡北段主要的目的层。在泰康—富裕缓坡带的宽缓鼻状构造上主要发育构造—岩性圈闭、断层遮挡圈闭和岩性圈闭,在泰来—甘南超覆带上主要发育岩性上倾尖灭圈闭和岩性圈闭。西部斜坡的油气侧向西运主要有3条路径:即南部路径、中部路径和北部路径,以中部路径为主,油气受规模较大的断裂、地层尖灭线和微幅度构造遮挡富集成藏。

| Abstract: | The northern sector of the West Slope,Songliao Basin was a simple slope,which could be divided into two zones from the east to the west, namely, the Taikang-Fuyu gentle slope zone and the Tailai-Gannan onlap zone. The depositonal formation could be divided into three structural layers: the fault-sinking,depressing and reversion ones, and hydrocarbon might not be enough generated from the autochthonous source rocks of three structural layers. The Qingshankou Formation and the first and second members of Nenjiang Formation were major target beds because oil and gas came from the neibouring Qijia-Gulong Depression. In wide and low-dip nose-structures in the Taikang-Fuyu gentle slope zone,there were three kinds of traps, namely, the structural-lithologic trap, fault-trap and lithologic trap. In the Tailai-Gannan onlap zone, there were two kinds of traps, the lithologic upward pinchout trap, as well as lithologic trap. Oil and gas were accumulated through the lateral migration and its pathways were controlled by tectonic ridge line and fault-lithology ridge line. There might existed three oil and gas migration pathways towards west in the southern, middle and northern parts respectively, with the middle migration pathway being the most important. In the migration pathways oil and gas were accumulated by the main faults, the stratigraphic pinchout line and the low amplitude structures. |
