一、理论依据油田水与一般水有迥然不同的特征: 1.矿化度极高,可达200克/升或更高; 2.为NaHCO_3盐水或CaCl_2盐水,氯化物含量很高,尤其是NaCl的含量可达47.5％以上;
First, the theoretical basis Oilfield water and general water have very different characteristics: 1. Extremely high salinity, up to 200 g / L or higher; 2. NaHCO_3 brine or CaCl_2 brine, high chloride content, especially NaCl content of up to 47.5% or more;
