The steady-state flows in drill pipe and in annulus are analyzed and the variations of pressure, gas void fraction, and multiphase-flow density along the well depth are simulated.
举例分析在环空和钻柱内的稳定流动过程中，随井深增加，压力、含气率、多相流体密度等的变化规律；
Large bypass ports open automatically as drill pipe is run into the vertical or horizontal wellbore, diverting mud into the annulus above any restrictions.
当钻杆进入垂直或水平井段时，大孔径旁通自动打开，将泥浆无阻碍导入环空。
