摘　　要：乙烯醋酸乙烯共聚物∶分散剂∶降凝剂按1∶1∶1.2的配比溶于有机溶剂中,制成油基清防蜡剂,考察了防蜡剂加量对防蜡率的影响,测定了清防蜡剂的溶蜡速度。结果表明,对于柯克亚有代表性的两口油井油样A和B,该防蜡剂都有较好的清防蜡效果,防蜡率可达85%以上,常温常压下,溶蜡速度为4.2 mg/(mL.min),并且随着温度的上升、含水率的下降,溶蜡速度增加。Oil soluble paraffin inhibitor was prepared with the molar ratio of ethylene acetate copolymer,dispersant and depressant of 1∶1∶1.2,effect of paraffin inhibitor amount on ratio of paraffin inhibition was studied.The rate of dissolve was determined.For the representative oil samples A and B,the inhibitor had a better effect.The ratio of paraffin inhibition was over 85%.Under the ambient temperature and pressure,the dissolve rate was 4.2 mg/（mL·min）,and as the temperature increasing,the moisture content declined,rate of melting wax increased.
