摘　　要：根据多级别断层的空间组合、密集程度及对油气的控制作用,首次将济阳坳陷内断层划分为15个断层聚集带,这些断层聚集带控制着济阳坳陷断块油藏的空间展布。受构造、沉积、成藏等因素的影响,济阳坳陷断块油藏构造更加破碎、纵向含油小层多,油水关系更加复杂,并且具有层间非均质强、原油性质差异大等特点。按照断块油藏的储量规模和密集程度不同,将坳陷内断块油藏在平面上划分为3个级别区域:Ⅰ类区域储量规模大、丰度高,是断块油藏开发的主阵地;Ⅱ类区域储量规模和丰度均次之;Ⅲ类区域资源贫乏。该研究为断块油藏的进一步高效开发指明了方向。Faults in Jiyang depression are divided into 15 fault gathering zones according to spatial combination,intensive degree and the control action on oil and gas. The fault gathering zones dominated spatial distribution of the fault block reservoirs. As affected by factors such as structure,deposition and hydrocarbon accumulation,the fault block reservoirs in Jiyang depression are more complicated in structure,vertically have more oil layers and complicated oil-water relationships,moreover,the reservoirs are characterized by severe interlayer heterogeneity and big difference in oil properties. Based on the size of oil reserves and the degree of intensity,the fault block oil reservoirs in Jiyang depression are divided into three regions: Region I has a big size of reserves and high reserves abundance,is the principle region of oil development; Region II has less reserves size and abundance; and Region III is resource-poor.
