Embodiment

[0035] figure 1 It is a schematic structural diagram of the upper and lower well device 100 provided by the embodiment of the present invention, figure 2 For the cross-sectional view of transporting the crawler 010 to the bottom of the well for the upper and lower well device 100, please refer to figure 1 and figure 2 shown.

[0036] The embodiment of the present invention provides an up and down well device 100, which is used to be installed at the well head, and the crawler 010 is transported into the well or sent out from the well through the up and down well device 100. The situation that the crawler 010 hits the well wall during the process of going up and down the well 020 and causes equipment damage is avoided.

[0037] Because the existing crawler is lowered to the bottom of the well or pulled out from the bottom of the well by the operator with a rope, in the process of lowering or pulling up, due to the shaking during operation, the crawler will more or less col...

Abstract

The embodiment of the invention provides a well ascending and descending device, and relates to the technical field of downhole operation. The well ascending and descending device comprises a wellheadsupport, a telescopic assembly and a pod used for containing a to-be-conveyed piece. The telescopic assembly is arranged at the wellhead support, is connected with the pod and is used for driving thepod to ascend and descend so as to send the to-be-conveyed piece into or out of a well. The well ascending and descending device is reasonable in design and simple in structure, and a crawler can beautomatically conveyed through the well ascending and descending device, so that the probability that a device is damaged due to the fact that an existing crawler collides with the well walls during the well ascending and descending process is reduced, meanwhile, the labor intensity of the operators is reduced, and the safety performance during the operation process is improved.

Description

technical field [0001] The invention relates to the technical field of downhole operations, in particular to a device for going up and down wells. Background technique [0002] At present, the crawler goes up and down the well by the operator through a rope. During the process of going up and down the well, manual operation will easily cause the crawler to collide with the well wall. Contents of the invention [0003] The object of the present invention includes, for example, providing a device for going up and down a well, which can stably send the crawler into or out of the well, and reduce the probability of the crawler colliding with the well wall during the process of going up and down the well. [0004] Embodiments of the present invention can be realized like this: [0005] In the first aspect, an embodiment of the present invention provides a device for going up and down wells, including a wellhead support, a telescopic assembly, and a pod for accommodating parts ...
