摘要
原油中所含的石蜡,它能够形成大晶块蜡,是造成蜡沉积而导致油井堵塞的主要原因。目前国内油田大多采用化学药剂清、防蜡技术,热力清蜡等技术。清防蜡作为油井日常维护的重要工作耗费了大量的人力物力。化学药剂清、防蜡作为油井最主要的清防蜡措施,对于油井的清防蜡效果起着至关重要的作用。因此,优化油井加药方式、提高化学清防蜡的措施效果,对于油井的正常生产将起着积极的指导意义。
In the crude oil, there contains paraffin wax, and it can form the megacryst block. It＇s the main course of wax deposition and oil well jamming. At present, domestic oil fields mostly use the chemical and the thermal ways to prevent and clear the wax. As the important routine maintenance, it consumes the massive manpower and physical resources. The chemical ways of prevention and clearance of oil well wax is the most vital measure, it plays the very important role for the effect of wax prevention and clearance. Therefore, optimizing the ways of the chemical injection, and improve the effect, will be very useful for the regular production of oil well.
