英文摘要 | The crystallization processes of oilfield brine components from the Nanyishan area at temperature between -18.90 and -30.90 degrees C were studied by a self-designed refrigeration instrument and the precipitation temperatures of the first and second salts were measured accurately. The concentrations of the major ions (Ca2+, Mg2+, K+, Cl-, B2O3, Na+) in the liquid phase of the brine at different temperatures (from -18.90 to -30.90 degrees C) were determined by chemical analyses. The solids obtained at low temperature were identified and the phase changes of the oilfield brine at temperatures between -10.0 and -30.0 degrees C were monitored in situ by subzero temperature X-ray powder diffraction. The results show that the first salt (hydrohalite) precipitates at -19.10 degrees C and the ice and NaCl-2H(2)O co-precipitate at -23.55 degrees C. |
