翘板活动在找油中的应用

翘板活动是地壳波状运动中的一种型式,主要有两种活动方式。一种是发生在台地或盆地之某一隆起为枢纽的翘板活动;另一种是以断裂为枢纽的翘板回转。这种翘板回转,多在盆地沉积建造的晚期强烈活动,并促进盆地沉积中心的迁移。显然翘板活动对沉积建造和含油气盆地的成生发展都具有重要意义。本文从“地壳波浪运动与镶嵌构造”观点出发,对我国大陆及海域上几个主要含油气盆地的翘板活动的特征与油气成生关系作了初步探讨。 

APPLICATION OF THE CONCEPT OF THE SEE—SAW ACTIVITY IN SEARCHINC FOR OIL

See-saw activity is one type of crustal wavy movement.This activity has occured from west to east and even from land to sea across the Chinese continent during various geological time.It takes the uplifts(or intrabasinal sub-uplifts)and the fault zones between platform and basin as the axis in its see-saw rocking turn,controlling the growth and development of the basin and the distribution of oil and gas.This article makes a preliminary approach to the relationship between the major petroliferous basins and the see-saw activity on the basis of the concept of crustal wavy movement and mosaic tectonics.The effect of this see-saw activity upon the formation of oil and gas deposits is also discusssed.
