Study in Kinetics of Barium Sulfate Crystallization Process of Oilfield Injection

Abstract:

With conductivity measurement in different concentrations of barium chloride, sodium sulfate, sodium chloride solution, their concentration-conductivity equation is obtained. Through mathematical conversion, the relation between sulfuric acid root ion in the solution, barium ion conductivity and the concentration is showed as: X=4.1744×10^-6Y-6.8544×10^-5,which is used to reflect the undissolved salt barium sulfate crystallization in the solution. Conductivity online measuring device is established, which can Intermittently test barium chloride, sodium sulfate solution of different concentrations, and detect the change of electrical conductivity in the process of crystallization of homogeneous barium sulfate in real-time. the different stages of crystallization process is determined by analysis of the conductivity curve. Through data processing to concert concentration into conductivity, so that the kinetic equation of barium sulfate crystallization process are obtained.
