查询词典 casing pipe

ABSTRACT Drilling time will be lasted and lateral force on casing exerted by drill pipe will increase in case of drilling deep well, ultradeep well, high inclined hole, extended reach well and horizontal well, therefore, friction and wear between casing and drill pipe became a severe problem.

在深井、超深井、大斜度井、大位移井及水平井中，钻井时间延长、钻柱作用在套管上的侧向力增高，因此套管和钻柱的摩擦与磨损问题越来越突出。

Drilling time will be lasted and lateral force on casing exerted by drill pipe will increase in case of drilling deep well, ultradeep well, high inclined hole, extended reach well and horizontal well, therefore, friction and wear between casing and drill pipe became a severe problem.
