| 摘 要： | 每种防砂方法对各种因素有各自的适应性。根据文献资料和现场调研 ,对各种防砂方法的适应性进行了归纳 ,建立了防砂方法适应条件知识数据库。应用模糊数学原理将每一种因素划分为若干个模糊集合 ,根据适应条件知识库 ,引入隶属函数和隶属度 ,计算了各种防砂方法对井的适应性。同时利用权重系数调节各个因素的重要程度 ,并以此建立了防砂方法的综合模糊技术评判模型 ,从中得到各种防砂方法的技术评判因子。再根据评判因子优选出技术上可行的若干防砂方法 ,应用不同寿命方案对这些方法进行经济评价 ,最后选出技术上合理、经济上可行的最优防砂方法 ,为油田防砂提供决策依据

| Abstract: | Every sand control method has its adaptability for each element. The adaptabilities of sand control methods are analyzed. The knowledge database containing the adaptability conditions of most methods is constructed. Based on fuzzy mathematics, each method can be divided into a few fuzzy sets. And with the supporting of the database, the adaptability of every method can be calculated by subordinate function. This fuzzy assessment model can be applied to calculate the technical index of all the sand control methods and select a certain method reasonable in terms of technology. The economic evaluation models for different life span are used to evaluate the above selected methods. In this way, an optimum sand control method for a well can be determined. |
