摘要
以断层相关褶皱理论为指导,依据构造建模和准噶尔南缘中段典型构造分析的成果,将准噶尔盆地南缘断裂分为3种断裂模式:山前逆冲断裂模式、浅部滑脱-逆冲断裂模式、深部滑脱-逆掩断裂模式。分析了3种断裂的力学机制和断裂样式。结合油气系统分析,认为南缘油气主要来自于深部侏罗系、二叠系,要使油气在勘探目的层内成藏,断裂样式的良好配置是油气成藏的关键。以典型构造为例,进一步分析了断裂的配置关系和油气成藏的机理。
The fault in southern margin of Junggar basin is divided into three fracture patterns based on theory of fault-fold correlation, the structural model and typical structural studies, such as piedmont thrust faulting pattern, shallow slippage-thrust faulting pattern and deep slippage-thrust faulting pattern, including analyses of their mechanisms and faulted styles. This paper suggests that the hydrocarbon source in southern margin of Junggar basin originates from deep Permian and Jurassic strata, and that good configuration of the faulted styles is the key factor for hydrocarbon accumulation. Also, the correlation of fault configuration and the mechanism for hydrocarbon accumulation are analyzed in detail by taking its typical structures as example here.
