摘　　要：目的:探究断坡油气藏分布特征规律与成藏主控因素。方法:结合流体包裹体均一温度法、成藏指数计算和断坡油气藏生烃速率的方式,从三个方面分析与断坡油气藏分布与成藏相关的各项数据的变化情况,根据分析结果确定分布特征规律及成藏因素。结果:研究区域的油气藏分布特征包括两方面,第一,油气聚集区与走滑断层相邻,其分布方向与断层基本吻合;第二,从西南至东北地区的油气储集层呈现出天然气-油气-储层的近NW向展布。成藏主控因素包括包裹体温度、含油程度等。结论:研究区域主控因素较多,造成该区域成藏模式复杂,在实际开展资源开采时应当针对具体成藏模式选择合理开采方法,确保开采效率和开采质量。Objective:To explore the distribution characteristics of fault-slope oil and gas reservoirs and the main controlling factors of accumulation.Methods:Combined with the method of fluid inclusion homogenization temperature,accumulation index calculation and hydrocarbon generation rate of fault-slope oil and gas reservoirs,the changes of various data related to the distribution and accumulation of fault-slope oil and gas reservoirs were analyzed from three aspects.As a result,the distribution characteristics and accumulation factors were determined.Results:The distribution characteristics of oil and gas reservoirs in the study area include two aspects:first,the oil and gas accumulation area is adjacent to the strike-slip fault,and its distribution direction is basically consistent with the fault;second,the oil and gas reservoirs from the southwest to the northeast show natural gas.-Near-Nw distribution of oil and gas-reservoir.The main controlling factors for accumulation include temperature of inclusions and degree of oil content.Conclusion:There are many main controlling factors in the study area,which result in the complex accumulation model in this area.In the actual development of resource mining,a reasonable mining method should be selected according to the specific accumulation model to ensure the mining efficiency and mining quality.
