摘要:
Drill cuttings accumulating in a deviated wellbore during drilling are swept out by including a weight material in the drilling fluid, the weight material being removable by screening but not so large as to damage pumps, eg in the range -95% 30 mesh to +95% 100 mesh. The cuttings and weight material are removed from the circulating drilling fluid by screening.
摘要(中):
通过在钻井液中包括重量材料来清除在钻井过程中积聚在斜井中的钻屑,所述重量材料通过筛选可移除但不会太大以至于损坏泵,例如在-95%30目至+95 %100网格。 通过筛选将钻屑和重量材料从循环钻井液中去除。
