摘　　要：油田注水中BaSO_4结垢损害模型参数的准确性决定模型的可靠性。为了提高模型参数的准确性,研究一种计算BaSO_4结垢损害模型参数的新方法。以BaSO_4结垢动力学模型为基础,通过岩心驱替实验记录不同的驱替压力。通过Matlab编程求解超越方程,计算BaSO_4结垢预测模型中动力学系数和地层损害系数的精确值,详细推导BaSO_4结垢损害模型,改进了用浓度测量模型参数的传统方法。The accuracy of parameters of BaSO4 scaling damage model determines the reliability of the model during oil field water injection. In order to improve the accuracy of the model, a new method for calculating the parameters of BaSO4 scaling damage model was designed in this paper. Based on the BaSO4 scaling kinetics model, different displacement pressure was recorded through the core displacement experiment. The exact value of the dynamic coefficient and the formation damage coefficient were calculated through transcendental equations by Matlab programming to deduce BaSO4 scaling damage model in detail and improved the traditional concentration measurement mod- el parameter.
