Abstract: After studying Shengtuo Oilfield,which has been developed by water-flood for 36 years,and which has been become into high water cut stage,the dynamical geologic process of development liquid was brought forward.The geologic environment,the power source,the fashion and the types of the process are discussed.The process controls mechanism that causes the changes of macroscopic and microcosmic reservoir parameters.Due to the long period of water-flooding development,the process can take place chronically.Under the process,the parameters of reservoir between different stage of water cut change regularly.The process also controls the mode and distribution of remaining oil.This new concept is very important to the adjustment,rooting potential work and tertiary recovery for high water cut reservoir.

Key words: dynamical geologic process, liquid, change of reservoir parameter, remaining oil, Shengtuo Oilfield

摘要： 研究了注水开发36年、含水已高达95%处于特高含水阶段的胜坨油田二区,提出油藏开发流体动力地质作用是控制研究区储层宏观、微观和渗流三大类参数变化规律和变化机理及剩余油形成分布的主因,建立了油藏开发流体动力地质作用的概念,论述了产生的地质环境、动力来源及动力作用方法.论证了油藏开发流体动力地质作用能长期持久进行的原因.
