目前国内成批生产的传动链条,在石油钻机上使用,一般反映寿命较短。例如,一盘用在钻机上的爬坡链条,在打一口3000米左右的油井(约2000小时)后,往往就要降级使用。对这个问题,我们组在参新套筒滚子传动链国家标准制订工作期间,在到大庆油田,胜利油田、大港油由等单位进行一般性调访中有所了解。最近又在江汉石油管理局钻采设备研究所 At present, mass production of domestic transmission chain, used in oil rigs, generally reflect a shorter life expectancy. For example, a climbing chain used in a rig often has to be downgraded after a 3000-well well (about 2000 hours) has been drilled. On this issue, our group in the new sleeve roller drive chain national standard-setting work, to the Daqing Oilfield, Shengli Oilfield, the big oil by the flat and other units to understand the general.
