摘　　要：油井补孔是油田常用的、比较有效的增产措施之一。补孔可以增加或调整油井的开采厚度、层系,使油井获得更高的产油量。而补孔是否见效,关键在于是否选择了合适的目标井层。将TOPSIS(逼近理想点排序)方法和AHP(层次分析)方法结合建立新的优选方法。首先介绍TOPSIS和AHP原理及计算步骤,然后依据AHP建立油井补孔措施的影响因素层次结构,确定各影响因素的权重,最后通过TOPSIS法计算各个候选井层与正理想点的相对贴近度。根据相对贴近度对各个井层排序。从而确定优选井层。该优选方法对油田动态分析人员有较好的应用价值和实践指导意义。Perforation measure is one of commonly used, more effective measures to increase production of oil field. It can increase or adjust the thickness and formation for the oil well,and make the well get higher output. The key whether perforation measure is successful or not, lies in whether to choose the appropriate target layer. TOPSIS（closing to ideal point） method and AHP（analytic hierarchy process） method were combined to establish a new optimization method. At first, TOPSIS and AHP principles and calculation steps were introduced, and then the hierarchical structure of influence factors of oil well perforation measures was established on the basis of AHP, the weight of each influence factor was determined, finally relative closeness degree of the candidate well layers and positive ideal point was calculated by the TOPSIS method. According to the relative closeness degree, each layer well was sorted to determine the optimum well layer.
