漏失处理可以作为挤压作业或现场应用进行补救. 另外, preventive treatment can be deployed when drilling through a formation with a known history of losses; this entails continuous addition of particles to the circulating drilling fluid or through regular, 重复扫描.
通过连续添加进行预防性处理
该处理方法的设计基础是,当钻进已知有漏失的地层时,在循环钻井液中连续添加颗粒. The main challenge is to maintain a required particle size distribution and concentration in the drilling fluid; typical concentrations range from 12 to 20 lbm/bbl [34 to 57 kg/m3].
