摘　　要：依据测井资料计算储层含水率,根据含水率确定了濮城油田沙一段水淹等级划分的标准。在精细沉积微相研究的基础上,运用储层建模软件,结合水淹等级划分标准,在沉积微相模型的约束下,利用确定、随机建模方法预测了濮城油田沙一段相控水淹模型,结果表明不同的沉积相区其油层的水淹程度和特征明显有差别。与其他建模方法建立的模型对比分析表明,相控下的随机水淹模型比较符合油田开发过程中的水淹状况及规律,符合储层发育及其非均质性分布规律,可信度高。预测结果为剩余油的预测和开采提供了更加符合实际的重要依据。通过研究发现,相控水淹研究为油藏水淹规律及特征的预测判断提供了非常有用的新方法。According to the reservoir water cut calculated by well logging data,the division criterion of waterflooding class for the first member of Shahejie Formation in Pucheng Oilfield is formed in terms of the water cut.On the basis of the study of fine sedimentary microfacies,used the reservoir modeling software and combined with the division criterion of waterflooding class,the facies-controlled water cut model of the first member of Shahejie Formation in the oilfield is established through the use of stochastic modeling under the restriction of sedimentary microfacies model.The result shows that the waterflooding degrees and features are obviously different in different sedimentary facies.The result,compared with the models established by other methods,shows that the facies-controlled stochastic waterflooding model accords with the waterflooding status and rules during oilfield development,and is in agreement with the rules of development and heterogeneity distribution of reservoir.It is more dependable.The predicted results can provide the effective foundations for the prediction and exploitation of remaining oil.Study result shows that the facies-controlled waterflooding study can provide the new method for predicting the laws and characteristics of reservoir waterfloding.
