The Experiment of CO2 Pollution and Treating in Silicate-Based Drilling Fluids

Abstract:

Article Preview

Through simulation experiment of CO2 invading into drilling fluids that viscosity and yield point are increased dramatically and drilling fluids is in a bad rheology. The concentration of HCO3- and CO32- both are increased, the concentration of OH- and pH value of drilling fluid both are reduced. It does not meet the drilling requirement as the concentration of CO2 is too high, so we must eliminate it as soon aspossible. The glue soluting with KOH and CaO through some Lab experiments have optimized, which has a better performance for prevention and management of CO2 pollution.
