摘　　要：我国陆上油藏大多数是平面非均质油藏,注水井的注入水容易形成优势水流通道使油井发生水淹水窜,因此需要判断出油井的主要来水方向,对来水层位进行调剖,减少无效注入水,提高注水效率。针对这种情况,基于多元线性回归理论,以D油田油井1-1为例建立油水井之间的多元线性回归模型,运用SPSS软件对模型进行求解,并经检验证明回归模型有效;最终寻找出油井1-11主要来水层位为2-11GIII、2-12GIII、2-12GI、1-13GIII、2-14GIV、2-14GI。此方法方便快捷,可对调剖井层的选取提供依据。Continental reservoirs are mostly areal heterogeneity reservoir in China.The injection water is easy to form preponderance flow path in the oil well,which results in water flooding.So judging watered-out direction of producing well to reduce the invalid water injection efficiency by profile control is necessary.Using the theory of multiple linear regression to establish multivariate linear regression model between oil and water,based on well 1-11 of D oilfield,and using SPSS software to solve model,it proves that the regression model is effective.Finally find out the mainly the Wateredout Direction of well 1-11 are 2-11 GIII,2-12 GIII,2-12 GI,1-13 GIII,2-14 GIV,2-14 GI.This method is convenient and efficient which can provides the reference for the selection of profile control wells and layer.
