输油管线结蜡直接影响油井的生产,结蜡严重的还会发生输油管线堵塞现象。多年来,国内外的有关工程技术人员对此展开了大量的研究工作,但是无论采取那种清蜡方法,都需关井停产。从而,不仅增加了采油工人的劳动量,也影响了原油的产量。近年来,长庆石油勘探局钻采工艺研究所进行子自封式弹射投球阀的设计工作,经过一年多的艰苦努力,现已投入观场应用,取得了比预想要好的效果。该装置采用浮动弹簧装置密封,可以随时调节 Waxing of oil pipelines directly affects the production of oil wells. Serious waxing can also cause oil pipeline blockage. Over the years, domestic and foreign engineers and technicians have carried out a large number of research work, but no matter what kind of cleansing method, shut down the need to shut down. Thus, it not only increases the labor of oil recovery workers but also affects the production of crude oil. In recent years, Changqing Petroleum Exploration Bureau Bureau of drilling technology for sub-self-styled bouncing ball throwing valve design work, after more than a year of hard work has now put into the application of the concept, and achieved better results than expected. The device uses a floating spring seal, can be adjusted at any time
