该文介绍了Ｏｄｄｏ－Ｔｏｍｓｏｎ预测五种硫酸盐和碳酸盐垢的方法。该方法除考虑对温度、压力和离子强度进行校正外，还考虑了ＣＯ２的逸度和它在油水中的分配，从而使预测碳酸盐垢的可靠性得到改善。这种方法可根据所需资料预测任何一种油、气井是否结垢。
This article describes Oddo-Tomson’s prediction of five sulfate and carbonate scale methods. In addition to the correction of temperature, pressure and ionic strength, the method takes into account the fugacity of CO2 and its distribution in oil-water so that the reliability of predicting carbonate scale is improved. This method can be based on the required information to predict any kind of oil and gas wells are scaling.
