Problems solved by technology

[0005] In the existing workover work platform, the connecting pipe and the main body of the platform are usually rigidly connected. Under normal conditions, the blowout preventer and the connecting pipe at the wellhead only bear the vertical downward positive pressure. Phenomena such as land subsidence or ground subsidence will cause the main body of the platform to tilt, which will cause the BOP and connecting pipes to bear additional lateral force and affect the service life of the connecting pipes and BOPs

Embodiment Construction

[0017] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] In the present invention, the terms "first" and "second" are mainly used to distinguish different components, but do not specifically limit the components.

[0019] Such as figure 1 and figure 2 As shown, the workover work platform of this embodiment includes a platform main body 1, on which a pipe string operation port is arranged, and the pipe string operation port is connected with a connecting pipe 6, and the connecting pipe 6 is movably connected to the platform through a ball hinge mechanism. On subject 1.

[0020] Specifically, the ball hinge mechanism includes a first fixed ring 3 sleeved on the outer wall of the connecting pipe 6, a second fixed ring 2 and a pressure plate 5 s...

Abstract

The invention discloses a well repair working platform which comprises a platform body. The platform body is provided with a pipe column operation port. The pipe column operation port is communicated with a connecting pipe. The connecting pipe is arranged on the platform body in a movably connected mode through a spherical hinge mechanism, so that flexible connection between the platform body and the connecting pipe is realized. When top-exceeding support or ground subsidence or other phenomena happen to the platform body, the platform body will do rotational motion relative to the connecting pipe without increasing lateral force on the connecting pipe, and therefore the connecting pipe, a blowout preventer and the like will not be damaged.

Description

technical field [0001] The invention relates to the technical field of oil drilling and workover equipment, in particular to a well workover work platform. Background technique [0002] After the oil well has been exploited for a period of time, there may be problems such as blockage, casing rupture, and damage to the oil well pump. At this time, workover operations are required. Workover operations require the transportation, lifting and lowering of oil pipes and other strings, and disconnection of upper and lower pipes. A series of operations such as columns. [0003] Traditional workover operations basically rely on manual operations, requiring 4-5 people to cooperate with the operation, which has high work intensity, low efficiency, harsh working environment, and many safety risks. With the advancement of technology, mechanized equipment has gradually appeared to replace part of the labor, such as the power catwalk instead of manual transportation of the pipe string bet...
