摘　　要：针对复合驱中使用的化学驱剂中有聚丙烯酰胺、表活剂和碳酸钠，研究了不同温度下碳酸钙结晶沉淀过程中晶核生成和晶粒长大的速度及活化能。同时研究了聚丙烯酰胺的存在对其影响。Consideration of scale deposition is important for the crude oil recovery. The formation of crystal nucleus, the growing rate of grain and the activation energy in the formation of calcium carbonate scale at different temperature are studied when chemical drive, which includes polypropenylamide, surfactant and sodium carbonate is used in combined drive. The effect of the polypropenylamide exits on the scale deposition was studied also.

关 键 词：结垢 碳酸钙 聚丙烯酰胺 温度 化学驱油
