煤层气清洁压裂液减阻性能评价

Evaluation on Drag Reduction Performance of clean Fracturing fluid for Coalbed Methane

阐述了清洁压裂液的作用机理,影响减阻的因素,介绍了国内外研究与应用情况,总结了清洁压裂液的优缺点。通过对清洁压裂液的增稠、携砂性能进行筛选,提出使用阳离子表面活性剂1831和水杨酸钠复配。实验得出最优浓度配比,确认了压裂液体系,并测减阻率,记录浓度和温度对减阻率的影响结果。

The action mechanism of cleaning fracturing fluid was introduced as well as the factors influencing the drag reduction.Its research and application situation at home and abroad was discussed,and the advantages and disadvantages of the clean fracturing fluid were summarized.Through a series of experiments,the optimal concentration ratio of clean fracturing fluid was screened,and the drag reduction performance was evaluated.
