【Abstract】 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.更多还原
