摘　　要：油井结蜡是油井日常管理工作中经常遇到的问题,虽然清蜡和防蜡方法层出不穷,但大多需要外界资源和物料的支撑,很难利用油气田自身工艺流程实现。通过仔细剖析油井结蜡原因,综合考虑油井现有生产流程,提出利用高温低含蜡油井热洗高含蜡油井的方法,最终实现清蜡和防蜡的目的,有效延长了油井清蜡周期,产生了良好的经济收益。The wax produced by oil wells is a common problem in daily management of the oil well.Although there are many ways to remove and prevent the wax,but most of them need the support of external resources and materials and are difficult to be realized by using the oil and gas field own process flow.By carefully analyzing the causes of wax formation in oil wells and considering the existing production process,we come up with a method of hot washing high wax oil wells with high temperature and low wax content,and finally realizes the purpose of wax removal and wax prevention,effectively prolongs the wax removal period of oil wells and generates good economic benefits.
