Studies on the Rheological Reaction Kinetics of Fenugreek Gum with Organ Boron Compound in Delayed Crosslinking Process

摘要

The research object is a kind of fracturing fluid consisted with Fenugreek gum and organ boron BCL-61. The influence of temperature, shear rate, the ratio of conversion of BCL-61, initial concentration of organ boron and the initial viscosity of Fenugreek gum on its rheological characteristics under fracturing process are investigated. Meanwhile, employing the principles of rheology and reaction kinetics, the rheological reaction kinetic equation is established. The results show that under fracturing process the forecasted variance of viscosity of Fenugreek gum by this equation is in good agreement with experimental data.
