摘　　要：从 Ca CO3晶体的形成机理入手 ,研究了高盐度水中 Ca CO3晶体形成过程中晶核生成阶段和晶粒长大阶段 Ca2 +浓度、温度、盐度对晶核生成速率常数和晶粒长大速率常数的影响 ,得出了晶核生成速率常数和晶粒长大速率常数不随浓度变化 ,随温度增加而增加 ,随盐度增加而减少的规律。In consideration of mechanism of the forming of CaCO 3 crystal,the effects of concentration,temperature and salt content of the crystal core formation and its particle growing on the constant of generating rate of crystal and the growing rate of crystal particles are studied during the forming of CaCO 3 crystal in water of high salt content Laws are given that the constant of crystal core forming rate and the crystal particle growing rate are not changed with the variation of concentration and are enhanced with increasing of temperature,and reduced with the increasing of salt content,which provides the theoretical basis for preventing water from scaling in oilfields
