摘　　要：厚油层油藏高含水期隔夹层对油田的开发具有重要影响。陈堡油田陈3断块泰州组一段三砂层组(K2t1^3)油藏为中孔-中渗厚油藏,采用水平井加常规井组合开发模式,目前已到高含水开发期,油藏内部隔夹层引起的储层非均质是影响剩余油的主要因素之一。在密闭取心井隔夹层研究的基础上,动静态结合研究纵向19个隔夹层类型、封挡性能、平面纵向等分布特征,结合油藏概念模型模拟总结隔夹层控油模式,为后期开发调整挖潜剩余油提出建议。Interbedding of thick reservoir in high water cut stage has important influence on oilfield development. The K2t1^3 reservoir of Chen 3 fault block in Chenbao Oilfield is a medium-porosity and medium-permeability thick reservoir,where the development model of horizontal well and conventional well combination was adopted. Now it has entered the stage of high water cut development. The reservoir heterogeneity caused by interlayer in the reservoir is one of the main factors affecting the remaining oil. Based on the study of interlayer in sealed coring wells, we combined static and dynamic analysis to study the distribution characteristics of 19 interlayer types, sealing performance, plane and vertical distribution,etc. And combined with the reservoir conceptual model,we simulated and summarized the interlayer oil control mode, and put forward suggestions for later development and adjustment of tapping potential remaining oil.
