摘　　要：从技术角度介绍了道威尔公司清洁压裂液技术在国内的现场应用情况,特别是在四川的应用情况。现场应用试验结果表明,清洁压裂液属无固相压裂液体系,具有液体摩阻低、滤失小、携砂能力强、混砂比高、易于破胶、返排速度快、对地层污染小等特点,是一种适合砂岩油气储层加砂压裂施工的液体体系。This article introduces the field applications of the ClearFRAC fluid of Dowell Co. in China, especially in Sichuan. Field results indicate that the ClearFRAC fluid is a solid free fluid. The fluid has many features, such as lower frictional resistance, lower fluid loss, stronger proppant - carrying capacity, higher blending ratio and quick backflowing velocity. When flowing back, it has lower damage to formation. It is a sand fracturing fluid system suited for sandstone reservoir.
