海洋钻井平台铁钻工主要结构形式浅析

Analysis on Main Structure Forms of Iron Roughneck in the Offshore Drilling Platform

铁钻工是海洋钻井平台管子自动化处理装置的组成部分之一,能实现对钻具的上、卸扣作业,有效提高管子处理的自动化水平。介绍了铁钻工上、卸扣的工艺流程,并根据运移装置的不同,对国内外现有铁钻工的主要结构形式进行了归类,对各类铁钻工的特点进行了分析。

As component of the automatic pipe handling device, the iron roughneck can make up and break out the drill string connection, thus the iron roughneck can improve the automation level of pipe handling effectively. This article introduces the technological process of making up and breaking out the drill string connection, then classifies the main structure forms of ex-isting iron roughneck according to the different moving devices, and analyzes characteristics of these kinds of iron roughnecks.
