精细地质研究在低渗透油田动态开发中的应用

Application of Fine Geological Study in Dynamic Development of Low Permeability Oilfield

对低渗透油田而言,当其进入高含水开发中晚期后,储层会不同程度的出现非均质性状况,严重影响开发效果。所以,有必要在油田开发过程中构建精细地质模型,对储层进行精细预测,有效降低油田开发风险,同时提高开发经济效益。简要分析了低渗透油田在储层非均质性方面所体现的基本特征,并论述了精细地质动态开发模型构建思路及方法,最后提出精细储层地质模型。

In the low permeability oilfield,when it enters the middle and late stage of high water cut,the heterogeneity of the reservoir will appear in different degree,which will seriously affect the development effect.Therefore,it is necessary to construct a fine geological model in the process of oilfield development,and to make fine prediction of the reservoir,effectively reduce the risk of oilfield development,and improve the development economic efficiency.The basic characteristics of low permeability reservoirs in reservoir heterogeneity are briefly analyzed.The idea and method of constructing fine dynamic geological exploration model are discussed. Finally,the geological model of fine reservoir is proposed.
