用综合评判方法优选压裂井层

Optimization of Fractured Formation With Comprehensive Identification Fuzzy Theory

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 in fracturing By lots 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
