摘　　要：本文综述了油田水中CaCO_3、CaSO_4、BaSO_4结垢趋势的几种常用预测技术,结合矿场实例介绍了各技术在长庆油田的应用,简介了长庆油田和山东大学合作建立结垢预测模型、研制计算机软件的工作结果。The methods of predicting the tendency of oilfield water to deposit CaCO_3,CaSO_4, BaSO_4 and SrSO_4, single and in mixture, are reviewed. In particular, Stiff-Davis' criterion SI for CaCO_3, solubility criterion S of Skillman et al. for CaSO_4, experimental procedure for BaSO_4, Jacques' criterion Q/K_(sp) for SrSO_4, computerized simulating model Vescal Ⅱ of Vetter et al. and the improved model of Yuan et al. for mixed sulfates are extensively discussed and illustrated with examples taken from Changqing Oil Fields or foreign literature sources. The latest results in a University-Oil Field joint program on predicting mixed salts deposition from determing laboratory solubility data to software are presented breafly.
