Marine riser tensioner slip system and use method

Abstract

The invention discloses a marine riser tensioner slip system and a use method thereof. The marine riser tensioner slip system is arranged on a drill floor, and comprises a tensioner guide rail assembly and a guide pulley guide rail assembly; the tensioner guide rail assembly comprises tensioner guide rails, tensioner bases and tensioners, the tensioner guide rails are arranged on the left end faceand the right end face of the drill floor, the tensioner bases are arranged on the two tensioner guide rails, and the tensioners are arranged on the upper end faces of the two tensioner bases; the guide pulley guide rail assembly comprises guide pulley guide rails, a pulley base and guide pulleys, the guide pulley guide rails are arranged on the lower end face of the drill floor in the length direction of the drill floor, the guide pulley bases are arranged on the lower end faces of the guide pulley guide rails, and the guide pulleys are arranged on the lower end faces of the guide pulley bases. According to the sliding system and the using method, sliding operation of a traditional steel wire rope type marine riser tensioner between two wellheads can be achieved, and the requirement thata drilling ship or a drilling platform or other floating drilling devices adopt double-wellhead operation is met.

Description

technical field [0001] The invention relates to a sliding system and a using method, in particular to a sliding system and using method of a riser tensioner. Background technique [0002] As the exploration and development of oil and gas resources move towards deep water and ultra-deep water areas, deep water drilling technology and equipment have become a hot spot for development. Deep water drilling equipment requires more advanced technical indicators such as operating water depth and drilling depth, and puts forward higher requirements for the configuration of drilling systems. . Most of the current mainstream deepwater floating drilling devices are equipped with dual wellhead operating systems to improve drilling efficiency. [0003] The riser system of the floating drilling unit is supported by the axial tension or upward buoyancy acting on the top of the riser. During offshore drilling operations, the tensioner controls the stress of the riser system and affects the...
