目前,国外的修井机,按其传动和工作特点的不同,可分为普通修井机,液压修井机和盘管修井机。后两种是近期发展的新技术。虽然国外近年来研制了多种型式的修井机,但是无论在陆上还是在海上,用于修井作业的大多数修井机仍然是柴油机驱动,以机械传动方式为主的普通修井机。 At present, the workover rig abroad, according to the different characteristics of its transmission and work, can be divided into ordinary workover rig, hydraulic workover rig and workover rig. The latter two are new technologies developed in the near future. Although many types of workover rigs have been developed abroad in recent years, most of the workover rigs used for workover operations are diesel-powered and workover-based common workover rigs, both on land and at sea. .
