研究了矿化度较高的油田水中，离子强度、高矿化度及其它因素对ＣａＣＯ３结垢趋势的影响，建立了ＣａＣＯ３结垢倾向的数学模型和判据，并编制了相应的软件．根据油田现场检测的水质数据，计算结垢指数ＣＩ值，即可预测ＣａＣＯ３结垢倾向．该预测与室内实验及现场检测的结果基本一致．
The effects of ion concentration, mineralization degree and other factors in the oil field water on CaC03 scaling tendency have been investigated. Methematic model and cri- terion for scaling tendency have been established. Computer software has been also drown up. The prediction for CaC03 scaling tendency can be made according to the water quality da- ta and calculated scaling index C1 value. The prediction is basically in accordance with the experimental results and in-situ inspected results.
