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。
Three eposodes of Himalaya movement had considerable appearences in SongliaoBasin.The first one happened between Late Tertiary and Early Quaternary.The regionalcompressive stress of NE-SW direction resulted by the effect of Indian Plate led to theformation 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 ledto a large scale of hydrocarbon migration and accumulation,forming a number of anti-cline trapped hydrocarbon pools represented by Daqing placanticline.The third episode inHolocene restored the NE-SW compression that occurred in the first episode,resulting ina series of new hydrocarbon traps or hydrocarbon zones of NW-direction,and seriouslyreformed the NE-directional anticline trapped hydrocarbon pools.It is suggested that themain target of oil and gas exploration in Songliao Basin is to find new structural traps orhydrocarbon enriched zones of NW-direction.
