采用模糊综合评判方法,全面考虑了影响压裂效果的多种因素,求解了压裂过程中的选井选层问题。针对各
种影响因素,在大量数理统计和理论求解的基础上,给出了可靠的权重和等级划分,建立了相应的数学模型和求解模型,对
油井(层) 是否可采取压裂措施作出定量判断。经用文南油田实际数据进行计算验证,该方法实用可行。

The identification of wells and formations to be fractured are determined by geologic features and injection-production performance. Using comprehensiviy fuzzy theory , the factors of effecting the fracturing efficiency were considered to solve the problems infracturing. By lot s of numerical statistics and theory solution , the trust worthy weight and grade classification of each factors were given , and the mathmatical model and solved model were established to determine the fracturing measures quantitatively. This method combine subjective factors with objective factors to consider the effecting factors.
