Abstract: The current dynamic allocation method in Henan oi lfield is mainly based on static data.There are too many parameters,calculatio n process is complicated,and therefore it is impossible to carry out predictio n.A gray correlation analysis method with dynamic and static data integrated to gether is presented in this paper.The gray system theory is introduced in oilfi eld development to simplify geologic parameters.A gray correlation model is es tablished between oil and water output of producers and injection of injectors .This model has been applied in Shuanghe oilfield.The operation process is sim ple and application effects are good.
