摘　　要：利用岩心,地震和测井等基础数据,分析沉积相演化,研究油水在垂向和平面的分布规律及主控因素。由于研究区的主要特征是"多油气来源,多期充注",并且区域有大量密集断裂带,断裂切割和砂层的断续分布,断裂的纵横分布具有导流作用,全区油水在垂向上没有统一的油水界面和明显的分布规律。通过利用分断裂系统的方法研究油水分布规律,平面上油水分布规律明显的地区主要集中在研究区的西北部和中东部。整个研究区没有统一的油水界面,但从南往北,油水相对的界面越来越深。Based on core,seismic and logging data,the evolution of sedimentary facies is analyzed. The vertical and horizontal distribution of oil and water and the main controlling factors are studied. Because the main characteristics of the study area are "multi-oil and gas sources,multi-stage filling",there are a large number of dense fault zones in the area,the discontinuous distribution of fracture cutting and sand layers. The vertical and horizontal distribution of fracture has the function of conduction. There is no uniform oil-water interface and obvious distribution law in the vertical direction of the whole area. The oil-water distribution law in the plane is studied by using the method of split fracture system. Distribution regularity is obvious,mainly concentrated in the northwest and central and eastern parts of the study area. There is no uniform oil-water interface in the whole research area.From south to north,the oil-water interface is getting deeper and deeper.
