摘要
描述了几种水中常见离子(包括:K+、Na+、Ca2+、Mg2+、Al3+、Cl-、SO42-)对压裂液的黏度和抗温抗剪切性能的影响。其中K+、Na+、Cl-、Mg2+和SO42-对压裂液的性能影响较小。而Ca2+由于与交联剂硼砂反应生产沉淀,减弱了压裂液的抗温抗剪切性能。同样,在pH=7.0时,Al3+也减弱了压裂液的相关性能。
This paper describes the effect of several common ions(including K^+,Na^+,Ca^2+,Mg^2+,Al^3+,Cl^-,SO4^2-) in water on the viscosity and the performance of temperature resistance and shear resistance of the fracturing fluid. K^+,Na^+,Cl^-,Mg^2+ and SO4^2- has little impact on the performance of fracturing fluids. Because Ca2+ reacts with the crosslinking agent(sodium tetraborate) to form precipitation, weakened the performance of temperature resistance and shear resistance of fracturing fluid. Similarly,in pH=7.0,Al^3+ has also weakened the related performance of fracturing fluids.
