近几年来,水力切割技术在国内外的研究和应用越来越普遍,已经涉及到工业、医疗以及食品加工等多个领域。其中绝大部分是用于切割加工。本文基于水力喷砂切割技术的原理和优点,从多方面探讨了井下作业中水力喷砂切割技术的积极作用,包括井口井壁清障,维修井下封堵井、水力压裂井等,说明水利喷砂切割技术在解决井下作业难题上,具有非常重要的意义。
In recent years, the research and application of hydraulic cutting technology at home and abroad is more and more common, and it has been involved in many fields such as industry, medical treatment and food processing. Most of them are for cutting. Based on the principles and advantages of hydraulic sandblasting, this paper discusses the positive effects of hydraulic sandblasting technology in downhole operation from many aspects, including the failure of wellbore wall, maintenance of downhole plugging wells and hydraulic fracturing wells, Sandblasting cutting technology to solve the problem of underground operations, has a very important significance.
