高效低伤害瓜胶压裂液体系在苏里格的应用

Application of Efficient and Low-damage Guar Gum Fracturing-fluid System to Sulige Gasfield

介绍了高效低伤害压裂液体系的组成,对常规压裂液与高效低伤害压裂液的流变性能、压裂液悬砂性能、破胶液性能、压裂液伤害性能进行对比。对实验结果进行了分析,并在苏里格气田进行了现场试验。结果表明,高效低伤害压裂液体系的性能高效,低伤害压裂液体系成胶性能、耐剪切性能、悬砂性能、破胶性能好,伤害低,能够满足目前苏里格气田水力压裂施工工艺和储层要求。

This study presents a fracturing- fluid system with efficiency and low damage, and its composition, and some experimental results on its various behaviors. Moreover, field experiments in Sulige gasfield were carried on. Results show that the system has not only some better behaviors of forming gum, shear resistance,sand suspension, and breaking gum, but also low damage, which may meet the requirements of hydraulic fracturing.
