摘　　要：通过瓶试法测试了丙烯酸酯类三元共聚物型石蜡稳定剂对中国南海某海上油田高含蜡原油产液破乳效果的影响规律。结果表明,单独应用时,此类石蜡稳定剂在高蜡原油乳化液的破乳实验中没有表现出明显的破乳作用;而当它与破乳剂SP169一起应用时,此类石蜡稳定剂可以明显增加实验中采用的高含蜡原油乳化液的脱水速率,显著地降低净化油的含水率,但对脱出污水的含油率影响不大,这表明石蜡稳定剂与破乳剂之间有一定的协同作用;实验结果还表明,原油乳化液中的含蜡量不同时,达到最佳处理效果时所添加的石蜡稳定剂的量不同,原油中石蜡含量越高,达到最佳处理效果时相应的石蜡稳定剂的用量越高。The influence of acrylate terpolymer paraffin stabilizer on wax-bearing crude emulsion breaking effect in offshore field was analyzed by laboratory experiment,the results showed that,when the paraffin stabilizer was applied alone in wax-bearing crude,the demulsification was unconspicuous;when used together with demulsifier SP169,the anhydration rate of wax-bearing crude was quickened,the water content ratio of cleaned oil was reduced;In order to obtain optimum emulsion breaking effect,when paraffin content in crude oil emulation was different,the dosage of paraffin stabilizer was also different,higher paraffin content in crude,the dosage of paraffin stabilizer was higher.
