Abstract

The invention discloses a load test tool for a sleeve tensioner and a testing device including the load test tool. The load test tool comprises a connecting plate, wherein the connecting plate comprises a supporting portion, a transition portion and a connecting portion. The front surface and the rear surface of the top of the supporting portion outwards extends to form first cylindrical web plates, and the first cylindrical web plates are used for being connected with a top drive. The front surface and the rear surface of the bottom of the supporting portion outwards extends to form positioning plates pressed on the top face of the sleeve tensioner. The front surface and the rear surface of the bottom of the connecting portion outwards extends to form second cylindrical web plates, and the second cylindrical web plates are used for being connected with a barge. The testing device comprises the load test tool. The high safety is ensured, operation is simple, test load safely and quickly acts on the sleeve tensioner by utilizing the tool in a narrow sleeve tension platform, the strength of the tool is ensured, hoisting operation is facilitated, and the test cost is saved.

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...
