摘　　要：油田的注入水会引起储层岩石特性的变化,从而导致油气水的渗流特征发生改变。以前的报道往往是通过检查井对应层位物性的变化来推断由注水引起的储层改变,其不足之处,一是岩石对应性差,二是把开发过程中所有措施的影响混杂在一起。本次研究以真X-6断块天然岩心为研究对象,通过室内实验研究了解该储层长期注水开发对储层物性变化。Water flooding can cause changes of rock characteristics in reservoir,and then make oil,gas and water seepage characteristics change. In previously report, it often by checking the physical changes of the well＇s corresponding layer to infer changes in reservoir properties caused by the water flooding. It has two inadequacies, one is the rock＇s corre- spondence difference, another is it mix all the impacts of the development process. This study we use natural rock core of Zhen35-6 as the research object, through indoor experi- mental we study and understand reservoir nature change caused by long-term water flooding in Zhen X-60ilfield.
