The advantage of this method is that the actual torque acting on …
钻完方钻杆。
在钻井过程中，方钻杆的侧向力作用常常导致旋转控制头损坏，造成事故。
In the process of drilling, the rotating control head is often damaged by the lateral force of the kelly, and this may lead to serious accident.
方钻杆补心的内径通常与方钻杆的外径（通常是四方钻杆或六方钻杆）相匹配。
The kelly bushing (KB) has an inside diameter profile that matches that of the kelly, usually square or hexagonal.
根据钻杆的结构特点，设计了探头距离可调的适用于圆钻杆和方钻杆的探测小车。
According to the drillpipe structural characteristics, a dolly appropriate for drillpipe and Kelly detection is designed, of which its probe is adjustable.
方钻杆之后带动整个钻柱进行旋转，由于方钻杆是与钻柱的顶部用丝扣连接在一起的。
The kelly then turns the entire drillstring because it is screwed into the top of the drillstring itself.
方钻杆旋转器已经很大程度地替代了旋链，而正是旋链造成了钻台上的大部分伤害事故。
The kelly spinner has largely replaced the infamous spinning chains, which were responsible for numerous injuries on the rig floor.
方入是指发生了这样的情况，即方钻杆全部进入到补心内，导致钻井进程不能够继续下去。
Referring to the condition that occurs when the kelly is all the way down, so drilling progress cannot continue.
使用AISI 4145 H合金钢制造。方钻杆的末端和驱动截面和接头都符合API规范。
Kellies are made of AISI4145H alloy steel. The ends, driving sections and joints are produced and tested according to API specification.
方钻杆用于传递转盘或者方钻杆补心的旋转运动到钻柱上去，并允许钻柱在上提或下放的过程中旋转。
The kelly is used to transmit rotary motion from the rotary table or kelly bushing to the drillstring, while allowing the drillstring to be lowered or raised during rotation.
杂物堆放柜是井队分类堆放相对较小的钻机部件的地方，从钻头到转换短节，到提升短节到备用方钻杆等。
The junk basket is used by the rig crew to store an assortment of relatively small parts of the drilling rig, ranging from drill bits to crossover subs to lifting subs to spare kellys.
从方钻杆补心(KB)、钻台(DF)、底座或者地面标高(GL)到井中测量点或者井底的实际井筒长度。
The actual wellbore length from the kelly bushing (KB), derrick floor (DF), foundation or ground level (GL), to a point in the well or bottom of the well.
井深测量通常是指方钻杆补心高度，如补心高度8327英尺，就意味着在方钻杆补心以下有8327英尺的深度。
Depth measurements are commonly referenced to the KB, such as 8327 ft KB, meaning 8327 feet below the kelly bushing.
方钻杆补心的内剖面与方钻杆的外部形状(四方钻杆或六方钻杆)完全匹配，但稍微要大于方钻杆补心的尺寸，以便方钻杆能够上下自由运动。
The kelly bushing has an inside profile matching the kelly's outside profile (either square or hexagonal), but with slightly larger dimensions so that the kelly can freely move up and down inside.
方钻杆补心的内剖面与方钻杆的外部形状(四方钻杆或六方钻杆)完全匹配，但稍微要大于方钻杆补心的尺寸，以便方钻杆能够上下自由运动。
The kelly bushing has an inside profile matching the kelly's outside profile (either square or hexagonal), but with slightly larger dimensions so that the kelly can freely move up and down inside.
