Load test fixture for casing tensioner and test device including it

Abstract

The invention discloses a load test tool for a casing tensioner and a test device including the same. The load test tool includes a connecting plate, and the connecting plate includes a supporting part, a transition part and a connecting part; the front of the top of the supporting part Both the surface and the rear surface extend outwards with first cylindrical webs, and these first cylindrical webs are used to connect with the top drive; the front surface and the rear surface of the bottom of the support part extend outwards with pressing devices The positioning plate on the top surface of the casing tensioner; the front surface and the rear surface of the bottom of the connecting part are extended outwards with second cylindrical webs, and these second cylindrical webs are used to connect with the barge. connect. The test device includes the load test fixture as described above. The invention ensures high safety and is easy to operate. The test load is safely and quickly acted on the casing tensioner by using tooling in the narrow casing tension platform, which not only ensures the strength of the tooling, but also facilitates hoisting operations. Save test cost.

Description

technical field [0001] The invention relates to a load test tool for casing tensioner and a test device containing it. Background technique [0002] Currently, during jack-up offshore oil drilling, drill pipes are lowered into seawater and inserted into the seabed for drilling. In order to prevent the drill pipe from generating a large vertical upward impulse under the action of sea waves and currents, a blowout preventer is installed on the top of the casing tensioner, so that the drilling load part acts on the pipe through the blowout preventer. on the casing tensioner. At the same time, the length of the drill pipe perpendicular to the water surface is changed due to the lateral movement of the drill pipe due to temperature fluctuations and waves, so that the drill pipe generates a downward pulling force on the casing tensioner. The stress on the drill pipe provides support through the telescopic movement of the piston rod of the casing tensioner cylinder, which greatly...
