摘要
针对目前大牛地气田压裂酸化选井方法的经验性、盲目性,借助现代数学方法—模糊数学和系统工程层次分析原理,考虑影响选井选层因素的复杂性和不均衡性,将各因素按其在不同层次上对事物的影响程度分类,然后确定各因素最终的权重,形成了一种压裂酸化选井选层的模糊分析方法。应用该方法对大牛地气田的5口井进行了实例计算,优选出最适合压裂的井,符合现场施工实际,计算简单、方便,具有一定的现场实用价值。
The selection of wells of fracturing and acidizing has been conducted based on experience in the Daniudi gas field. A fuzzy analysis method is developed. This method employs modern mathematical methods of fuzzy mathematics and the analytic hierarchy of system engineering,considers the complexity and disequilibrium of the factors affecting the selection of wells and horizons of fracturing and acidizing,classifies these factors as per their respective effects on different hierarchies,and finally determines the weight of each factor. Particular calculation has been conducted for 5 wells in the Daniudi gas field. Candidate fracturing wells are selected. This method is simple and convenient and of certain application value.
