搞好泥浆净化,实现以低固相或无固相泥浆打井,是保证钻井泥浆循环系统正常工作,延长钻头使用寿命和加快打井速度的一个重要环节。但是现有的震动筛除砂法难于达到较高程度的净化要求。为了解决这个问题,目前国内外采用旋流除砂法和离心除砂法净化泥浆,其原理都是根据不同介质旋转时产生不同的离心力实现分离,取得较好的效果。为此,从 Doing a good job of purifying mud and realizing drilling with low solidity or without solid mud is an important step to ensure the normal operation of the drilling mud circulation system, prolong the service life of the drill and speed up the drilling. However, the existing vibrating screen sand removal method is difficult to achieve a higher degree of purification requirements. In order to solve this problem, the current domestic and international use of cyclone sand removal and centrifugal desilting mud purification, the principle is based on different media spin different centrifugal force to achieve separation, and achieved good results. To this end, from
