油井井筒结蜡原因及治理措施研究

Study on the causes of wax deposition in oil well bore and its control measures

针对油井井筒结蜡问题,对油井结蜡原因及规律进行分析,并提出合理的结蜡治理措施,为保障油井井筒的生产效率奠定基础。研究表明:介质的组分、井筒内的温度、井筒内外温度差等因素都将对井筒结蜡问题产生重要影响。因此,需要从化学清蜡、热洗清蜡以及化学清防蜡等角度入手,采取多种类型清防蜡措施,防止结蜡对井筒生产作业产生影响。

In view of the problem of wax formation in the well shaft,this paper analyzes the causes and rules of wax formation in the well shaft,and puts forward reasonable wax formation control measures to lay a foundation for ensuring the production efficiency of the well shaft.The research shows that:the composition of the medium,the temperature in the wellbore,the temperature difference between the inside and outside the wellbore and other factors will have an important impact on the wellbore wax formation problem.Therefore,it is necessary to take a variety of wax removal and prevention measures from the perspectives of chemical wax removal,thermal wax removal and chemical wax removal,so as to prevent the wax formation problem from affecting the wellbore production.
