渤南洼陷位于沾化凹陷中部,是济阳坳陷中的一个三级负向构造单元,洼陷内断层十分发育,按照规模和控凹(洼)程度,将第三系断层划分为三个级别,并分析了从Ek至Es1的断裂空间分布,分别指出其优势方向。经对比分析断层生长指数和断层活动速率两种定量化指标,按照断层的活动期次和活动特征,结合断层的级别以及平面上和剖面上的分布特征,有效判别出研究区内断裂活动的强度,分析出断层的活动期次以及与油气运移的匹配关系及不同级别断层在油气运移中的作用,从而指导油田勘探开发。
The Bonan Sag is located in the central part of Zhanhua sag and is a tertiary negative tectonic unit in the Jiyang Depression. The faults in the sags are well developed. According to the scale and the degree of depression, the Tertiary faults are divided into three And analyzed the spatial distribution of fracture from Ek to Es1, pointing out the dominant directions respectively. By comparing and analyzing the quantitative indexes of fault growth index and fault activity rate, the intensity of fault activity in the study area can be discriminated effectively according to the active period and active feature of the fault, the level of faults and the distribution characteristics on the plane and in the section , Analyzed the active period of the fault and the matching relationship with the hydrocarbon migration and the role of different levels of fault in hydrocarbon migration to guide the exploration and development of the oil field.
