摘　　要：王场油田潜三段北断块地区油藏由于对其沉积体系、储层分布认识不清,注水开发效果差,采出程度很低。从现代沉积学理论出发,充分利用岩心、钻井、测井等资料,深入研究了王场油田潜三段北断块地区的沉积特征,将研究区的沉积相类型定为典型的盐水湖泊三角洲,划分出其主要亚相类型为三角洲前缘亚相,并建立了该区的沉积相模式图,从而为下步老井挖潜及滚动开发指明了方向。Due to poor understanding on sedimentary system and reservoir distribution,the reservoir in Qian-3 member north fault block of Wangchang oilfield has bad waterflood-ing effect and low recovery. Based on modern sedimentology theory,making full use of coring,drilling and logging data,the in-depth study of sedimentary characteristics has been carried out. In the end,the study area has been defined as a typical saline lake delta,and delta front subfacies as its main sub-facies. The established sedimentary facies model dia-gram will provide guidance for potential exploration and roll-ing development of existing wells.
