Problems solved by technology
[0003] Due to the complexity of the riser assembly itself, there are manufacturing and assembly errors, and when the riser assembly is supported and placed, there are placement errors and deformation caused by gravity. The flange surfaces at both ends of the riser assembly may be in any space during the test position, such that conventional riser test rigs simply cannot align every pipe of the riser assembly
Therefore, the current riser test bench can only conduct performance tests on the six parallel pipes on the riser assembly one by one. The test procedure is complicated, time-consuming, inefficient, and labor-intensive; In line with the actual working conditions of the riser assembly, that is, the situation that all pipes of the riser assembly run at the same time cannot be tested

The invention discloses a pipeline testing device and particularly provides a marine drilling riser testing device which can be used for simultaneously testing six pressure pipes of a riser component. The marine drilling riser testing device comprises two pipeline plugging devices; each pipeline plugging device comprises a base, a plugging flange and a freedom degree adjusting system; the freedom degree adjusting systems are respectively mounted on the bases; the plugging flanges are mounted on the freedom degree adjusting systems and are adjusted in spacial position through the freedom degree adjusting systems; each freedom degree adjusting system at least comprises an X-axis rotating mechanism, a Y-axis translating mechanism, a Y-axis rotating mechanism, a Z-axis translating mechanism and a Z-axis rotating mechanism. Through the adoption of the freedom degree adjusting systems, the plugging flanges can be adjusted optionally in space through the mechanisms, so that the plugging flanges can be correspondingly sealed together with riser component flanges in any position, as a result, the six pressure pipes can be tested simultaneously.
Description
technical field [0001] The invention relates to a pipeline test device, in particular to a water riser test device for offshore drilling. Background technique [0002] When drilling at sea, it is necessary to install a riser between the subsea wellhead and the offshore drilling platform to establish a channel for mud to return from the subsea wellhead to the offshore drilling platform. The riser is submerged in seawater, and it has to bear complex and variable loads such as its own weight, ocean current impact, buoyancy, external seawater and internal mud pressure, drilling tool contact collision force, etc., and the working conditions are extremely harsh; at the same time, the riser assembly is a set of six The tube bundle composed of pressure pipelines consists of a main riser and five auxiliary pipes of different sizes and pressure levels arranged around the main riser (two hydraulic pipelines, well killing pipelines, H-level mud pipelines and throttling pipelines). pipe...
