以富林洼陷古近系沙三段底部构造图为基础，研究发现主要有3种走向的断裂体系，且都为正断层，平面上构成平行式、雁列式、斜交式组合，剖面上形成阶梯状、地堑和地垒、“Y”字形及花状组合。利用生长指数对4条主干断层和10条次级断层进行活动性研究结果表明，断裂活动东西向上具有早期“西强东弱”、晚期“西弱东强”的特征，南北向上具有早期“南强北弱”、晚期“南弱北强”的特征。成藏期，大部分次级断层活动较弱，少数断层消亡，侧向封堵作用较好；垦东断层和垦利断层活动强度较大，运移作用强烈，油气的最大优势运聚方向指向垦利潜山披覆构造。

Based on the fault system interpretation on the bottom structure mapping of the third member of Palaeogene Shahejie Formation in Fulin Subsag ,the results showed that there were mainly 3 types of strike faults which were all normal faults.According to the combination ,the faults can be divided into parallel ,echelon and oblique in the plane ,and step,gra-ben,horst,Y-shape and flower structure in profile .In this paper,fault growth index was used to study the activities of the 4 main faults and 10 second-order faults .The analysis indicated as follows:from west to east and from south to north ,faults activities became weaker at the early stage and became stronger at the late stage .At the stage of petroleum accumulation ,most of second-order faults had weaker activities and the rest were inactive or even died out ,so the plugging ability was prefera-ble.But at the same time,the activities and migration behavior of Kendong fault and Kenli fault were stronger than those of the second-order faults.The best way of oil -gas migration directs to the drape structure of Kenli buried hill .
