一、技术水平 (一)油井清蜡、防蜡油井清蜡、防蜡,是实现集输系统自动化的关键。据统计,在美国采油过程中,每年直接用于清蜡的费用约450—500万美元,苏联曼格斯拉克的一油矿清蜡费用占每吨原油成本的2.6％。国外油井清蜡、防蜡的方法: 1、机械方法清蜡、热法清蜡,这两种方法是国外常采用的,如加拿大在含蜡量较低的彩虹油田,用活动清蜡车清蜡,取消了井口清蜡装置。又如美国含蜡量16％的红洗油田,采用热油洗井清蜡。

First, the technical level (a) oil well de-waxing, anti wax paraffin waxing, wax, is the key to realize the automation of gathering and transportation system. According to statistics, in the process of oil recovery in the United States, the annual expenses for direct waxing are about 450-500 million U.S. dollars. The cost of a paraffin oil in the United Kingdom is 2.6% of the cost per ton of crude oil. Foreign oil well wax, anti wax method: 1, mechanical methods of wax cleaning, thermal waxing method, these two methods are commonly used abroad, such as Canada in the low wax content rainbow oil field, Wax, canceled wellhead waxing device. Another example is the United States 16% wax content of red wash oilfield, the use of hot oil wash well wax.
