Application of Optimal Membership Degree in Optimizing Well Completion Based on Fuzzy Analytic Hierarchy Process

How to choose the method of well completion is a complex system, which needs to consider all the aspects. In the optimum choice of horizontal completion, score method, the weighted average method and fuzzy comprehensive decision-making method have appeared successively. In the application of fuzzy comprehensive decision-making method, many scholars based on the Analytic Hierarchy Process determined the weight of each index and if this calculation schema optimally belongs to the best one, the completion method is prior. But the Analytic Hierarchy Process has its shortcomings. By means of Fuzzy Analytic Hierarchy Process, this paper explores the schema which optimally belongs to the best one and confirms that the well completion method is optimum.
