4. INSTRUCTIONS 指令

4.1. Breaking Out Connections with the Rig Tongs 用大钳卸扣

(1) The Floormen remove the safety latch springs and the tong pins and change the tong jaws to match the size of the pipe or tubular to be broken out.钻工打开安全弹簧和取下大钳销子，换上合适尺寸的钳头以匹配钻杆或管子的尺寸

(2) The Driller ensures that the safety latch springs are replaced on the tong pins.

司钻要确保大钳销子上的安全锁定弹簧被放到原位。

(3) The Floormen set the slips, or where applicable, the Driller sets the automatic slips.

钻工卡上卡瓦（如果有的话，司钻卡上自动卡瓦）。

(4) The Floormen engage the rig tongs on the drillpipe or tubular tool joint. (The breakout tong is placed on the top tool joint and the makeup tong is placed on the bottom tool joint).

钻工在钻杆或管子接头上上打上大钳（内钳打在上方接头上，外钳打在下方接头上）。

Note: Special attention must be made to ensure the rig tongs are placed above the hard facing on the tool joint.

注意：大钳必须打在接头耐麽层之上。

(5) The Floormen make the rig tongs bite by pulling on the tong jaw and pushing on the tong arm.

钻工通过拉钳头、推钳柄使钳子咬紧。

Note: The Floorman must properly place their hands on the rig tongs to prevent injury.

注意：钻工必须正确放置手的位置以免受到伤害

The Driller engages the breakout cathead and pulls on the breakout tong. This will cause the breakout tong to bite on the upper tool joint. At the same time, the makeup tong bites on the bottom tool joint. The connection is then broken.

司钻操作卸扣猫头拉动卸扣大钳，这会使卸扣大钳咬紧上部接头，同时上扣大钳咬紧下方接头 扣被卸开。

Note: The Driller must ensure that the cathead line is at right angle (90 degrees) to the tong arm. The Driller must note the breakout torque and mark the joints for further inspection if the breakout torque is not equal to or within less than 10% of the makeup torque.

注意： 司钻必须确认猫头绳与钳柄之间的角度垂直（90·），如果卸扣扭距不等于或小于上扣扭距的10％，司钻必须留意卸扣扭距并作好记号以便进一步检查。

(7) The Floormen spin out the connection using the air spinner, or if applicable, the Driller utilises the top drive to spin out the connection.

钻工使用气动旋扣器卸开扣，或者如果可能，司钻用顶驱卸开扣。

(8) The Floormen apply proper pipe dope into the thread box of the pipe joint.

钻工用合适的丝扣油涂抹接头母扣。

(9) The Floormen remove the rig tongs and tie them back safely out of the way.

钻工打开大钳，放置到安全位置并拴牢。

4.2. Making Up Connections with the Rig Tongs 用大钳上扣

(1) The Floormen remove the safety latch springs and the tong pins and change the tong jaws to match the size of the pipe or tubular to be made up.

钻工取下安全弹簧和大钳销子换上合适尺寸的钳头以匹配钻杆或管子的尺寸。

(2) The Driller ensures that the safety latch springs are replaced on the tong pins.

司钻要确保钳销上的安全锁定弹簧被放到原位。

(3) The Floormen set the slips and the Driller picks up a joint or a stand of pipe.

钻工卡上卡瓦，司钻提起一单根或一立柱。

(4) The Floormen apply pipe dope to the box and pin end of the connection thoroughly.

钻工均匀地在公、母扣上抹上铅油。

(5) The Floormen stab the pin end of the joint into the box of the joint in the rotary table.

钻工把公扣接头放进转盘上单根母扣接头内。

(6) The Floormen rotate the pipe into the box utilising the air spinner or where applicable, the Driller utilises the top-drive or the kelly spinner.

钻工用气动旋扣器旋上扣或者司钻用顶驱或方钻杆旋扣器上扣

The Floormen engage the rig tongs onto the drillpipe or tubular tool joint (The makeup tong is placed on the top tool joint and the breakout tong is placed on the bottom tool joint). The Floormen make the rig tongs bite by pulling on the tong jaws and pushing on the tong arm.

钻工在钻杆或管子接头上上打上大钳 （内钳打在下方接头上，外钳打在上方接头上）钻工通过拉钳头推钳柄使钳子咬紧。

Note: The Floorman must properly place their hands on the rig tongs to prevent injury.

注意：钻工必须正确放置手的位置以免受到伤害。

(8) The Driller engages the makeup cathead, pulls on the makeup tong causing the make up tong to bite on the top tool joint. At the same time, the breakout tong bites on the bottom tool joint. The Driller continues to pull on the makeup tong until proper torque is applied to the connection.

司钻操作上扣猫头拉动上扣大钳，这会使上扣大钳咬紧上部接头，同时卸扣大钳咬紧下方接头 司钻继续拉动上扣大钳直到达到合适地扭距

(9) After the connection has been tighten to proper torque, the Floormen remove the rig tongs and tie them safely out of the way.

用合适地扭距上紧接头后，钻工打开大钳，放置到安全位置并拴牢。
