近几年来,我们先后到任邱油田和江汉油田二十多个钻井队及有关部门,对不同型号钻机使用链条的情况进行了调查。在分析对比不同失效形式的链条后,我们认为,影响链条寿命的因素很多,除链条本身质量外,使用条件的好坏对链条的寿命影响极大。各型钻机由于润滑条件不同,链条的失效形式也不同,其使用寿命也就有很大的差别。以往有些资料介绍,国产链条的寿命一般为2000小时左右,而罗马尼亚链条可达5000小时。但是,从不同的使用条
In recent years, we have served in Qiu Oilfield and Jianghan Oilfield more than 20 drilling teams and related departments, different types of rigs using the chain were investigated. After analyzing the different types of failure of the chain, we believe that many factors affect the life of the chain, in addition to the quality of the chain itself, the quality of the use of conditions on the life of the chain have a great impact. Various types of drilling rig due to different lubrication conditions, the chain of failure of different forms, its service life will have a very big difference. Some information in the past, the life of domestic chain is generally about 2000 hours, while the Romanian chain up to 5000 hours. But from different usage strips
