The invention discloses a slippage exchange device for drilling rigs between offshore fixed platforms. The slippage exchange device comprises two rows of slipping guide rails and two rows of avoiding guide rails; slipping shoes are assembled on the slipping guide rails; the slipping shoes comprise slipping shoe plates horizontally arranged on the slipping guide rails; two pressure plates in parallel mutually are arranged below the slipping shoe plates; two rows of avoiding guide rails and two rows of slipping guide rails are vertically crossed; disconnected separated structures are adopted at the crossed positions of the slipping guide rails and the avoiding guide rails; cross reversing slipping abutment walls are arranged at the centers of the disconnected separated structures; slipping shoe passing separators are arranged between the cross reversing slipping abutment walls and broken ends of the slipping guide rails and the avoiding guide rails; two pressure plates are fixedly connected with the slipping shoe plates in a longitudinal and transverse position adjustable manner by bolts; drilling rig supporting legs are provided with longitudinal walking hydraulic cylinder ear plates and transverse walking hydraulic cylinder ear plates. According to the slippage exchange device for the drilling rigs between the offshore fixed platforms, which is disclosed by the invention, two drilling rigs can carry out exchange slipping between two offshore platforms and complete drilling and workover operations.
Description
technical field [0001] The invention relates to a sliding interchange device for a drilling and repairing machine between two fixed offshore platforms, in particular to a structure for sliding and exchanging the drilling and repairing machines of different types between two adjacent fixed offshore platforms. Background technique [0002] In recent years, the practice of building a four-legged (and above) fixed offshore platform based on the existing fixed offshore platform and realizing the equipment sharing of the two platforms has been initially applied in the Bohai Sea, which can effectively reduce the construction investment of oil and gas fields. In the past, in order to make full use of the drilling and workover rig resources of existing platforms, the practice of drilling and workover rigs sliding between two offshore platforms and drilling and workover operations has been applied. However, one drilling and workover rig often cannot take care of the drilling and worko...
