摘　　要：针对鄂尔多斯盆地胡尖山油田油层复杂、水力压裂措施效果不理想的问题,在统计分析胡尖山油田水力压裂历史数据的基础上,借助各因素对措施效果的影响权重灰色关联分析,建立了水力压裂措施效果模糊综合评判模型,并研发了应用软件。经胡尖山油田2004年至2007年水力压裂措施的448井次数据分析对比,该模型对措施效果预测的符合率为83.71%。对40口新井进行措施效果评判,预测结果符合率为80%。研究表明,该技术具有较强的针对性和学习性,可为该油区水力压裂的参数优化提供辅助。The Hujianshan oilfield in Ordos Basin has complex reservoirs and the results of hydraulic fracturing are not satisfactory. This paper analyzes the historical statistical data of hydraulic fracturing in this oilfield,performs gray correlation analysis of the influence weights of all factors on stimulation results,sets up a fuzzy comprehensive evaluation model of hydraulic fracturing effect,and develops application software. Data analysis and comparison of 448 well-times of hydraulic fracturing conducted in Hujianshan oilfield during 2004 to 2007 show that the coincidence rate is 83.71% when the model is used to predict stimulation results. And the coincidence rate is 80% when used on 40 new wells. The research shows that this technology is of high pertinence and learnability,and can provide assistance for parameter optimization of hydraulic fracturing in this oil province.
