双驱钻机理论是全新的钻机设计方法，它使得钻机和修井机的结构与操作得以大大简化。双驱钻机即可用于浮动钻井平台又可用于固定式钻井平台，并取消了带有绞车、钻柱补偿器等的大型井架，双驱钻机理论可使小型修井机象大型钻机那样使用，从而展示了钻井新方式及改善海上油田经济状况的广阔前景。 Double-drive rig theory is a new design methodology for rigs that simplifies the construction and operation of rigs and workover rigs. Dual-drive rigs can be used on both floating and stationary rigs, eliminating the need for large derricks with winches, drill string compensators, etc. The dual-drive rig theory allows small workover rigs to be used like large rigs Showing the broad prospects of new ways of drilling and improving the economic conditions of offshore oilfields.
