塔里木盆地塔中低凸起滑脱构造与分层构造变形
|
摘要
塔中低凸起作为古生代形成的凸起,是油气运移聚集的有利指向区,研究其构造变形特征对油气勘探具有重要的意义。应用地震和钻井资料,在地震资料解释和分层构造复原基础上,研究认为:(1)除塔中Ⅰ号断裂带部分段为基底卷入式外,塔中低凸起主要逆冲断裂以滑脱式为主,主逆冲断裂多在中、下寒武统膏盐层系滑脱;(2)盐上地层变形特征与盐下地层变形特征不同,盐上地层构造变形强度总体上大于盐下地层构造变形强度;(3)膏盐层系在分层构造变形过程中起到协调变形作用;(4)塔中低凸起分层构造变形主要受控于俯冲造山及膏盐层系滑脱作用。
Tazhong lower uplift forming during Paleozoic was a favorable area for hydrocarbon migration and accumulation,so it's very important to study the structural distortion character for petroleum exploration.Based on seismic and well data,seismic interpretation and restoration of balanced cross-sections were carried out,and the results indicate:(1) Besides basement involvement structures in the part segment of No.1 fault,the faults were dominated by detachment faults which formed in Middle-Lower Cambrian salt layers.(2) The deformation styles were different in the upon and underneath salt layers,and the distortion was stronger in the upon salt layer than that in the underneath salt layer.(3) The stratified deformation was coordinated by salt layers.(4) The stratified deformation was controlled by both subduction orogeny and decollement of salt layers.
