准噶尔盆地西北缘斜向挤压构造与油气分布规律
|
摘要
根据地面地质调查资料、卫星遥感影像地质解译成果、准噶尔盆地西北缘大地电磁测深剖面的最新解释以及地震剖面资料综合研究,认为准噶尔盆地西北缘斜向挤压构造是由该区发育的达拉布特左行走滑断裂、西北缘逆冲推覆构造以及北西向右行横向走滑断裂组成。其中,达拉布特边界断裂左行走滑作用是形成准噶尔盆地西北缘逆冲推覆构造和北西向右行横向走滑断裂的主要控制因素,西北缘逆冲推覆构造与北西向右行横向走滑断裂的交合部位是准噶尔盆地西北缘地区油气的主要聚集区域。
Data gathered from field survey,geological interpretation of satellite remote sensing images,and the reinterpretation of crustal magnetotelluric measurement data and comprehensive analysis of seismic data of the northwestern margin of Junggar Basin,indicate that the oblique compressional structuress in the study area is consisted of the Dalabute sinistral strike-slip fault,overthrust nappe in the northwestern margin,and NW-trending dextral transverse strike-slip faults.The sinistral strike-slipping of the Dalabute boundary fault controlled the development of the latter two structures,and the area between the two structures is considered to be the key zone for oil and gas accumulations in the northwestern margin of Junggar Basin.
