清蜡剂的效果对油井清蜡作业至关重要, 针对现阶段常用清蜡剂毒性大、易燃、溶蜡效率低等缺点, 通过室内实验研制了一种新型水包油型清蜡剂, 并在油田进行了试验. 制订了水包油型清蜡剂中不同添加剂及其含量对清蜡效率影响的实验方案, 分析确定最佳配方为55%混合有机溶剂、 17%混合型表面活性剂、 10%正己醇、 2%氯化钠、 3. 5%甲酸盐加重剂及水. 多项性能参数表明, 该清蜡剂性能明显优于常规油基清蜡剂. 两组矿场对比试验井的试验结果表明, 加入水包油型清蜡剂的单井抽油机载荷量分别降低25. 07%和48. 01%, 较加入常规清蜡剂的邻井分别高出20个百分点和33个百分点, 载荷量降低明显,应用效果良好. 该新型清蜡剂溶蜡效率高、成本低、环保性好, 推广应用前景广阔.

The effect of wax remover is critical for wax removing of oil wells. For the high toxicity, flammability, low wax dissolution rate and other shortcomings of commonly used wax removers, we developed a new type of oil-in-water wax re-mover in lab and tested in oilfields. We made experiment plans about the influence of different additives and their content on wax removing efficiency in oil-in-water wax removers, and determined the best formula consisting of 55% mixed organic solvent, 17% compound surfactant, 10% hexanol, 2% sodium chloride, 3. 5% sodium formate and water. Performance pa-rameters showed that the new wax remover was superior to conventional oil-based one. Test results of two groups of wells in-dicated that the load of a single well pumping unit could be reduced by 25. 07% and 48. 01% respectively after being added into oil-in-water wax remover, 20% and 33% higher than that of adjacent wells with conventional wax remover. The load was reduced remarkably and the application results were good. The new wax remover featured in high wax dissolution effi-ciency, low cost, good environmental protection, and broad prospect for application.
