钻机TC585天车强度分析

随着石油钻机不断发展,深井、超深井以及水平大位移井更广泛的应用于各大油田,对名义钻井深度,承载设备结构重量等方面的需求明显增加.天车作为石油钻机的重要部件之一,承担着井架起下放以及钻井起下钻等钻井过程的载荷.天车可靠性、安全性是钻机运转的重要保障.以8000m钻机的天车TC585为研究对象,对天车滑轮轴、快绳轮轴以及天车的关键焊缝及滑轮轴承进行强度分析.

Strength Analysis of TC585 Crown Block

With constantly development of drilling equipment, deep drilling, ultra deep drilling and large horizontal displace-ment rig are widely used in major oil fields, and demands are much increased in aspects of nominal drilling depth, bearing e-quipment weight, etc. As one of the most important components of the drilling rig, crown block bear the loading of rig liftingand laying down in drilling process, so reliability and safety of crown block are the important guaranty of drilling operation. Inthis paper, setting ZJ8000 drilling rig TC585 crown block as the research object, strength analysis of the crown sheave shaft,the fast-line sheave shaft, the key welding of crown frame, and the crown sheave bearing are made.
