| 摘 要： | 昆仑山前柯东构造带油气勘探潜力大,但其地下复杂构造制约着本区油气勘探。综合最新钻井、地震、非地震及野外露头资料,对柯东构造带柯东段进行构造建模研究,认为柯东段构造变形为两期,早期为圈闭形成期,与断层相关褶皱发育;晚期为调整期,高角度断层发育。两期构造变形作用控制着本区油气成藏、调整过程。

| Abstract: | Kedong Thrust Belt showed its great exploration prospect after the breakthrough in Well Kedong1.But the complicated structure holds up the exploration progress.Based on the analysis of drilling,seismic,CEMP and outcrop data,it can be concluded from the tectonic modeling analysis that the deformation occurred in 2 stages since Miocene.At the first stage,large-scaled anticlines were formed as fault-related folds.At the second stage,transpressional structure leaded to high-angle thrust which adjusted the former large-scale anticlines.The 2-stage deformation was corresponding to the former petroleum accumulation and latter adjusting.This recognition will guide the future exploration of the Kedong area. |
