【摘要】 根据四川盆地及邻区的新构造运动,天然发震机制、石油钻探、人工地震,构造圈闭形态变异及交切关系、储层或油气藏压力、卫星遥感信息解译等多方面资料综合分析得出,喜马拉雅三幕构造运动区域主压应力方向变化很大,早幕和晚幕运动为NE-SW向,中幕运动为NW-SE向。晚幕运动形成的北西向新油气构造圈闭,与中幕运动形成的北北东向及燕山中幕形成的北东东向含油气构造圈闭或油气藏复合叠加,形成了一大批复合背斜构造圈闭的油气藏,也是四川盆地油气勘探最佳远景区。更多还原

【Abstract】 Multidisciplinary analysis of data on the neotectonism, natural earthquake mechanism, oil drilling, artificial earthquake, variation in the forms of structural traps and their intersect, reservoir pressure, interpretation of satellite image indicates that the direction of the regional principal compressive stress during the Himalayan movement in the Sichuan Basim and its neighbourhood was variable: the direction in the early and late episodes was NE-SW, in the middle - NW-SE. The NW-trending structural traps in the late Himalayan movement superimposed upon the NNE-trending structural traps in the middle Himalayan movementto be superimposed upon the NEE-trending structural traps in the middle Yanshan movement were responsible for a great number of combination traps wich are prospect areaes for the oil-gas exploration in the Sichuan Basin.更多还原
