摘要: 通过新旧地震数据的对比和校正,应用盆地分析及盆山耦合的思想对和什托洛盖盆地及其周边进行构造解析;并应用平衡剖面技术了解盆地构造演化,得到以下认识:①和什托洛盖盆地是一个位于主逆冲带上盘的扭动-挤压型次生盆地,它起源于西伯利亚板块、哈萨克斯坦微板块、准噶尔微板块的相互碰撞与错动;②盆地早期演化从属于准噶尔地体,基底双重构造活动应早于晚三叠世,在此之前其作为准噶尔盆地的边界与内部是连通的;③盖层发育可分为四个阶段:初始发育期(T 3 –J 1 b)、快速沉积期(J 1 s–J 2 t)、整体沉降时期(K)和边界断裂复活时期(E–Q),其中侏罗纪为盆地的主要成盆期,也是构造变形最大的时期。

Abstract: According to the comparison and correction between latest and old seismic data, this paper presents the whole structural interpretation and evolution of Heshituoluogai basin using basin analysis theory, basin-mountain coupling idea and balanced cross section technique. it is concluded that: 1) Heshituoluogai basin originated from the collision and dip offset among Siberia plate, Kazakhstan micro-plate and Junggar micro-plate is a secondary compresso-shear basin situated on the hanging wall of major thrust belt; 2) the evolution of Heshituoluogai basin is subject to Junggar terrain, the double tectonic activities of its basement should be earlier than Late Triassic before which it was connected with Junggar basin as a boundary of it, and 3) the basin cover development can be divided into 4 stages: initial development stage (T 3--J 1 b), quick deposition stage (J 1 s-J 2 t), whole subsidence stage (K) and boundary faulting revival stage (E-Q), of which Jurassic is the main basin-formed period associated with largest structural deformation.

Key words: Heshituoluogai basin, basin-mountain coupling, thrust nappe, tectonic evolution, hydrocarbon accumulation
