drilling fluid discharge

用法例句

Applying finite element method,the dynamic characteristics of drill string with cone bit in straight hole were simulated,and the whirl,deformation and the dynamic stress in air drilling were compared with the ones in drilling fluid drilling.

应用有限元方法,仿真了空气钻井时斜直井眼中带牙轮钻头钻柱的动力学特性,比较了空气钻井和钻井液钻井条件下钻柱的涡动、变形以及动态应力状况,探讨了空气钻井钻柱失效的动力学机理。

Design and application of hydraulic drill pipe lay-down catwalk;

液压动力钻杆排放猫道设计与应用

Therefore,a kind of hydraulic drill pipe lay-down catwalk is designed.

针对目前我国钻机用钻杆坡道、钻杆猫道、钻杆排放架都是独立部件,需要单独运输,搬家车次多,组装和拆卸需要吊车,不具备向钻台自动送入单根及下放钻杆(或甩钻)功能的状况,设计了一种液压动力钻杆排放猫道。
