摘　　要：针对宝浪油田水化学特点 ,应用 Skillman和 Odd-Tomson方法分别预测硫酸钙垢、碳酸钙垢的结垢趋势 ,通过静态结垢试验证实了理论预测结果。研究结果表明 ,宝浪油田注水结垢只可能产生碳酸盐垢而不会产生硫酸钙垢 ;结垢成因是由于系统内的热力学不稳定性引起的 ,即注入水温度、p H值升高或地层内CO2 分压降低都会导致结垢。The scaling tendency of CaCO 3 and CaSO 4 in Baolang oilfield is predicted by using Oddo Tomson's equation and Skillman's method The result from the theoretical prediction is verified by static scaling test The mechanism of scaling is resulted from thermodynamic unstability, namely the change of temperature in injection water, pH variation or drop of CO 2 partial pressure in formation would result in scaling
