摘要/Abstract

摘要： 对叠加构造变形构造，变形时序、叠加构造形成的地球动力学背景及其与油气关系的综合研究表明，塔北隆起的叠加构造可以划分出：以二叠纪为形成高峰期的北西－南东走向的挤压构造，以三叠纪为形成高峰期的北东－南西走向的挤压构造，主要形成于渐新世－中新世的拉张构造，这三期构造在空间上、时间上复合叠加，从而在塔北隆起形成了轮南构造带、南喀－英买力叠加褶皱带以及羊塔克－提尔根负反转构造带等叠加构造变形区。上述叠加构造变形区均是有利的油气勘探区。

Abstract: Based on a comprehensive study of geological and geophysical data from the North Tarim Uplift, the authors investigated the deformational features, time and order, geodynamic background of superimposed structural deformation and hydrocarbon accumulation in the North Tarim Uplift. The superimposed structures can be identified as the NW-SE trending compressional structures and NE-SW trending compressional structures, which primarily acted in Permian and Triassic respectively, and the extensional structures formed during the Oligocene to Miocene. These superimposed structures compounded spatially, multipled temporally and produced three major superimposed structura1 deformation zones, i.e., Lunnan structural gone, Nanka-Yinmaili superimposed folds zone and Yangtake-Tiergen negative inversion structural zone. They are favorable for oil and gas prospecting.
