摘要：

据新构造运动、天然地震、钻探、人工地震、地层、构造形迹、卫星遥感等资料,认为喜山运动各幕在松辽盆地都有表现,第一、三幕运动主要受印度板块影响,产生的区域主压应力为 NE-SW向,第二幕运动主要受太平洋板块影响,产生的区域主压应力方向为 NW-SE 或近东西向。现今晚(三)幕期产生 NW 向构造的作用,对中(二)幕期和燕山晚幕期形成的 NE 向构造圈闭及其中的油气再运移和富集有重要影响。新生的 NW 向含油气构造圈闭或油气聚集带,是今后油气勘探的重要目标。

Abstract:

Three eposodes of Himalaya movement had considerable appearences in Songliao Basin.The first one happened between Late Tertiary and Early Quaternary.The regional compressive stress of NE-SW direction resulted by the effect of Indian Plate led to the formation of Xiao Hingganling Mountains and the second Songhuajiang-Nenjiang de-pressed zone.The second one took place between Middle and Upper Pleistocene.The com-pressive stress of NW-SE or nearly EW direction resulted by the effect of Pacific Plate led to a large scale of hydrocarbon migration and accumulation,forming a number of anti-cline trapped hydrocarbon pools represented by Daqing placanticline.The third episode in Holocene restored the NE-SW compression that occurred in the first episode,resulting in a series of new hydrocarbon traps or hydrocarbon zones of NW-direction,and seriously reformed the NE-directional anticline trapped hydrocarbon pools.It is suggested that the main target of oil and gas exploration in Songliao Basin is to find new structural traps or hydrocarbon enriched zones of NW-direction.
