The invention discloses a riser tensioner sliding system and a use method thereof. The riser tensioner sliding system is arranged on a drill floor and includes a tensioner guide rail assembly and a guide pulley guide rail assembly; the tensioner guide rail assembly includes Tensioner guide rails, tensioner bases and tensioners, tensioner guide rails are provided on the left and right end surfaces of the drill floor, tensioner bases are provided on both tensioner guide rails, and two tensioner The upper end surface of the base is provided with a tensioner; the guide pulley rail assembly includes a guide pulley guide rail, a pulley base and a guide pulley, and the lower end surface of the drill floor is provided with a guide pulley guide rail along the length direction of the drill floor, and the lower end surface of the guide pulley track is provided with There is a guide pulley base, and the lower end surface of the guide pulley base is provided with a guide pulley. The sliding system and using method provided by the present invention can realize the sliding operation of the traditional wire rope riser tensioner between two wellheads, and meet the requirements of double wellhead operations for floating drilling devices such as drilling ships or drilling platforms.
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...
