SAFETY INFORMATION 安全事項(xiàng)（1）The Driller must ensure that the Floormen are outside the area of the tongs before pulling on the tongs, if an abnormal amount of torque is to be applied during make up or break out.當(dāng)上、卸扣扭距異常時(shí)，司鉆拉大鉗前必須確認(rèn)鉆工站在大鉗區(qū)域之外。（2）Snub lines for the rig tongs must be inspected and be in good working order.鉗尾繩必須檢查并狀態(tài)良好。（3）Hanging lines for the rig tongs must be inspected and be in good working order吊繩必須檢查并狀態(tài)良好。（4）The Floormen must be instructed on proper placement of hands while operating the rig tongs.操作大鉗時(shí)，必須教導(dǎo)鉆工把手放在正確位置。3. STANDARD OPERATIONAL CONSIDERATIONS （ DO’S AND DON’TS） 標(biāo)準(zhǔn)操作注意事項(xiàng)（1）Always use two sets of rig tongs of the proper size to break out or make up connections. 要使用合乎標(biāo)準(zhǔn)尺寸的雙鉗上、卸扣。（2）The Floormen must lubricate rig tongs at regular intervals, and always before and after each trip 鉆工必須定期保養(yǎng)大鉗，如起鉆前和下鉆后。（3）The slack in the rig tong safety line must be sufficient for the tong to obtain full benefit from the pull of the cathead, but short enough to prevent half rotation of the rig tong 鉗尾繩的長(zhǎng)度長(zhǎng)短合適，足夠長(zhǎng)以滿足大鉗施加足夠的拉力，足夠短以避免大鉗的旋轉(zhuǎn)角度不夠。（4）Ends of the braided safety lines should be secured by thimbles which are properly cast, spliced or taluritclamped to prevent unravelling.14 / 158 安全繩的末端使用心環(huán)，心環(huán)要正確的鑄造，壓制或者用卡子以避免散開(kāi)。（5）Rig tongs must be kept clean to ensure proper operation. 大鉗必須保持清潔確保正確操作。（6）Rig tong dies must be inspect regularly and must be replaced when worn or damaged. Ensure that the tong dies are secured with safety pins. 鉗牙必須定期檢查，磨損和損壞的鉗牙一定要更換，要使用鉗牙安全銷(xiāo)。（7）Rig tong line pulleys and counterbalances must be inspected at regular intervals. 大鉗的懸掛滑輪和平衡配重必須定期檢查（8）Rig tong pins and hinges must be inspected regularly for wear and replaced if any wear is observed. 大鉗銷(xiāo)子和鉸鏈必須定期檢查磨損情況，如果磨損嚴(yán)重要更換。（9）Rig tong pins, shackle pins and bolts must be secured with the proper size split pins. 大鉗銷(xiāo)子，卸扣的銷(xiāo)子和螺栓必須配有合適尺寸的開(kāi)口銷(xiāo)。4. INSTRUCTIONS 指令 Breaking Out Connections with the Rig Tongs 用大鉗卸扣（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. 鉆工打開(kāi)安全彈簧和取下大鉗銷(xiāo)子，換上合適尺寸的鉗頭以匹配鉆桿或管子的尺寸（2）The Driller ensures that the safety latch springs are replaced on the tong pins. 司鉆要確保大鉗銷(xiāo)子上的安全鎖定彈簧被放到原位。（3）The Floormen set the slips, or where applicable, the Driller sets the automatic slips. 鉆工卡上卡瓦（如果有的話，司鉆卡上自動(dòng)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）. 鉆工在鉆桿或管子接頭上上打上大鉗 （內(nèi)鉗打在上方接頭上，外鉗打在下方接頭上）。Note: Special attention must be made to ensure the rig tongs are placed above the hard facing on the tool joint.注意：大鉗必須打在接頭耐麼層之上。（5）The Floormen make the rig tongs bite by pulling on the tong jaw and pushing on the tong arm. 鉆工通過(guò)拉鉗頭、推鉗柄使鉗子咬緊。Note: The Floorman must properly place their hands on the rig tongs to prevent injury.注意：鉆工必須正確放置手的位置以免受到傷害15 / 158（6）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. 司鉆操作卸扣貓頭拉動(dòng)卸扣大鉗，這會(huì)使卸扣大鉗咬緊上部接頭，同時(shí)上扣大鉗咬緊下方接頭 扣被卸開(kāi)。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： 司鉆必須確認(rèn)貓頭繩與鉗柄之間的角度垂直（90），如果卸扣扭距不等于或小于上扣扭距的10％，司鉆必須留意卸扣扭距并作好記號(hào)以便進(jìn)一步檢查。（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. 鉆工使用氣動(dòng)旋扣器卸開(kāi)扣，或者如果可能，司鉆用頂驅(qū)卸開(kāi)扣。（8）The Floormen apply proper pipe dope into the thread box of the pipe joint. 鉆工用合適的絲扣油涂抹接頭母扣。（9）The Floormen remove the rig tongs and tie them back safely out of the way. 鉆工打開(kāi)大鉗，放置到安全位置并拴牢。 Making Up Connections with the Rig Tongs 用大鉗上扣（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. 鉆工取下安全彈簧和大鉗銷(xiāo)子換上合適尺寸的鉗頭以匹配鉆桿或管子的尺寸。（2）The Driller ensures that the safety latch springs are replaced on the tong pins. 司鉆要確保鉗銷(xiāo)上的安全鎖定彈簧被放到原位。（3）The Floormen set the slips and the Driller picks up a joint or a stand of pipe. 鉆工卡上卡瓦，司鉆提起一單根或一立柱。（4）The Floormen apply pipe dope to the box and pin end of the connection thoroughly.
