摘　　要：在油田开发后期,地下仍存在大量剩余油。随着开发不断深入,储层常规的认识已无法摸清楚剩余油,油藏工作进入单砂体研究阶段。本文通过多口井的信息,结合单砂体接触关系,提出10种单砂体叠置类型,来确定单砂体的空间展布特征及连通关系,同时提出有效水驱储量控制程度参数,指导油藏开发方案的调整。In the late development of the oilfield, there are still a lot of remaining oil in the ground.With the development of development, the conventional understanding of reservoir has been unable to understand the remaining oil in the formation, and the work has entered a single sand body research stage.Based on the information of multiple wells and the contact relationship of single sand bodies, 10 kinds of single sand body superposition types are proposed to determine the spatial distribution characteristics and connectivity of single sand bodies.At the same time, the effective water drive reserves control parameters adjust the reservoir development program.

关 键 词：接触关系 单砂体 叠置类型 有效水驱储量控制程度
