本文简要的分析了油井结蜡的机理,阐明了结蜡的影响因素及预防措施。我厂的平均含蜡量大约为27.8%,属于特高含蜡油田,所以我厂的油井普遍受结蜡的影响严重,而油管、抽油杆和抽油泵的结蜡,会使抽油机载荷增加,泵效降低,降低了油井产能,有的甚至将井筒通道堵死,造成油井停产。本文主要介绍了一种清防蜡新方法——声波降粘防蜡技术。声波降粘防蜡技术具有工艺简单、管理方便、适应性强,防蜡效果好、对地层没有污染等特点。含蜡原油经过声波的过程,是一个具有剪切加热降粘,蜡晶网络破坏,介质均匀分散在液相中的过程。从而有效地起到降粘防蜡,延长油井结蜡周期的目的。 This paper briefly analyzes the mechanism of well waxing, clarifies the influencing factors and preventive measures of waxing. The average wax content of our plant is about 27.8%, which belongs to the ultra-high waxy oilfield. Therefore, the oil wells of our factory are generally affected by waxing. The waxing of the tubing, sucker rod and pump will make the pumping unit Increased load, pump efficiency decreases, reducing well productivity, and some even blocked the wellbore channel, resulting in oil well shutdown. This article mainly introduces a new method of anti-wax - anti-stick smelting wax technology. Acoustic wave viscosity reduction wax technology has the advantages of simple process, convenient management, strong adaptability, good anti-wax effect and no pollution to the formation. Waxy crude oil through the sound of the process is a shear heating viscosity, wax crystal network damage, the medium evenly dispersed in the liquid phase in the process. Which effectively play a viscosity-reducing wax, prolong the purpose of the well waxing cycle.
