摘要：为分析劫陷期张应力与构造反转期压扭性应力对丰乐地区葡萄花油层断裂发育与分布的双重影响，从断层，结合这两类断裂系统的分形特征，分别刻画了油源断层和晚期调整型断层分维值。研究结果表明：丰乐地区油气有利区主要分布于油源断层分维值的高值区、晚期调整型断层分维值的低值区，即丰乐地区的西北部以及中部地区：而丰乐地区东部三肇凹陷一朝阳沟阶地地区，后期调整性断层的分维值较高，后期断裂活动较强，使得保存条件较差，不利于油气聚集成藏。这一认识不仅有力地指导了丰乐地区油气勘探，而且为周边含油气区寻找剩余油提供了借鉴。

Abstract: In order to analyze the double influences of the tensile stress at the depression stage and compresso-shear stress in tectonic reversal period on the fracture development and distribution in Putaohua oil reservoirs of Fengle area, from the viewpoint of the faulted horizons and the stress forming environments of the faults, the activa-ting faults at different stages in the reservoirs were divided into the oil source fault and late-adjusted fault, integrat-ed with the fractal characteristics of these two kinds of the fault, the dimension classifying values of them were re-spectively described. The study achievements show that the favorable blocks in Fengle area are mainly distributed in the high-value region of the fractal dimension in the oil source fault and the corresponding low-value area of the lat-ter i. e. Northwest and Middle Fengle; while from Sanzhao Sag in East Fengle to Chaoyanggou Terace, the values of the latter are rather higher, the activities of the late fractures are rather stronger, these make the conservation
