摘要： 随着油田开采进入中后期，措施井的措施费用不断增大，措施效益持续下降。根据老君庙油田M油藏2008—2012年增产措施的特点，利用数据包络分析法（DEA）建立了措施井投入产出效率评价模型，并进行实例分析。研究发现：当取样本单元为有效单元时，广义DEA模型和传统DEA模型的结果是一致的;当取样本单元不是决策单元时，广义DEA模型给出的结果和传统DEA模型的结果是不同的。同时也可以得出：在2008—2012年，各项措施的投入产出效率都处于下降趋势；防砂措施的平均投入产出效率高于其他措施的投入产出效率，而侧钻大修措施相对于其他措施的投入产出效率则比较差。

Abstract: The operation cost for measure well was increasing and the measure efficiency was declining since Laojunmiao oilfield entered into the later period of development. This paper presented the characteristics of well stimulation in M reservoir of this oilfield during 2008-2012, developed the input-output efficiency evaluation model for the measured wells using data envelope analysis (DEA), and conducted a case study. Research shows that when sampling unit is effective unit, the generalized DEA model is the same as the traditional DEA model in the result; when sampling unit is not a decision making unit, the results from these two models are different. Also, it is suggested that during the period of 2008-2012, the input-output efficiency of the measures available tended to decline, in which the average efficiency of sand control was higher than those of other measures, and the efficiency of sidetrack overhaul was lower than the others’
