Deep salt cavern sonar measuring instrument simulation probe

Abstract

The embodiment of the application discloses a deep salt cavern sonar cavity measuring instrument simulation probe, which comprises a first connecting piece, a connecting line, a second connecting piece and a rod body. The first connecting piece is used for being connected with a cable. The strength of the connecting line is less than that of the cable. The second connecting piece is connected with the first connecting piece through the connecting line. The rod body is connected with the second connecting piece and located on the side, away from the first connecting piece. When the sonar needs to pass through a relatively thin wellbore to enter the deep underground to measure the volume, depth and other parameters of the cavity, the simulation probe can be placed in the wellbore first, and the simulation probe can pass through the deep part of the wellbore, thereby simulating the scene that the real sonar passes through the wellbore. By setting the strength of the connecting line to be less than that of the cable, when the simulation probe is stuck in the wellbore and cannot move up and down, the connecting line breaks earlier than the cable, thereby protecting the cable and avoiding damage to the cable.

Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of detection, in particular to a deep salt cavern sonar cavity measuring instrument simulation probe. BACKGROUND

[0002] With the rapid development of domestic salt cavern gas storage, compressed air energy storage, oil storage, helium storage and salt cavern carbon dioxide solidification technologies, the use of salt caverns is diversified, and the demand for salt caverns is rapidly increasing, especially for old storage. Whether it is a new storage or an old storage, the sonar needs to be used multiple times to pass through the thin shaft to measure the volume, depth and other parameters of the underground deep cavity during the entire construction or reconstruction process.

[0003] Generally, the depth of the salt cavern is nearly one kilometer, and the depth is nearly three kilometers. The depth is deep, and the shaft is thin. In addition, the creep of salt rock is relatively strong, and whether it is a new storage or an old salt cavity, the shaft is prone to deformation due to stratum movement, such as shaft damage, distortion, and even broken. Sonar monitoring is a relatively professional and accurate way to measure the related parameters of the underground cavity, but the sonar is expensive and the measurement requirements are strict. During the process of the sonar cavity measuring instrument entering the deep part of the shaft, it is easy to be stuck when encountering shaft breakage, distortion and other problems, which will cause great loss of cable breakage, sonar stuck in the shaft or falling into the cavity. SUMMARY

[0004] The present application aims to at least solve one of the problems in the prior art or related art.

[0005] To this end, the first aspect of the present application provides a deep salt cavern sonar cavity measuring instrument simulation probe, comprising:

[0006] A first connecting piece is used to connect with a cable;

[0007] A connecting line has a strength less than that of the cable;

[0008] A second connecting piece is connected with the first connecting piece through the connecting line;

[0009] A rod is connected with the second connecting piece and located on the side of the second connecting piece away from the first connecting piece.

[0010] In a possible implementation, the strength of the connecting line is three-fourths of the strength of the cable.

[0011] In a possible implementation, the deep salt cavern sonar cavity measuring instrument simulation probe further comprises a cover body, one end of which is connected with the first connecting piece, and the other end of which is connected with the second connecting piece, and the connecting piece is located in the cover body.

[0012] In a possible implementation, the cover body is a hollow circular truncated cone structure.

[0013] In an embodiment, the connecting line runs through the hollow structure along the axial direction of the cover.

[0014] In an embodiment, the first connecting member is provided with a convex ridge in the circumferential direction, the second connecting member is provided with a clamping groove in the circumferential direction, one end of the cover abuts against the convex ridge, and the other end of the cover is arranged in the clamping groove to limit the axial and radial directions of the cover.

[0015] In an embodiment, the deep salt cavern sonar measuring instrument simulation probe further comprises a connecting nut connected with the cable, and the connecting nut is threadedly connected with the first connecting member; and the second connecting member is threadedly connected with the rod body.

[0016] In an embodiment, a plurality of first stop protrusions are uniformly arranged on the outer circumferential wall of the first connecting member in the circumferential direction; and a plurality of second stop protrusions are uniformly arranged on the outer circumferential wall of the second connecting member in the circumferential direction.

[0017] In an embodiment, the rod body is a hollow structure, and a balance hole is arranged through the rod body along the radial direction.

[0018] In an embodiment, the first connecting member, the connecting line, the second connecting member, the rod body and the cover are coaxially arranged.

[0019] Compared with the prior art, the present application has at least the following beneficial effects:

[0020] The deep salt cavern sonar cavity measuring instrument simulation probe provided by the embodiment of the application can be connected with the cable through the first connecting piece, the connecting line is connected with the first connecting piece and the second connecting piece, the second connecting piece is connected with the rod body, the first connecting piece, the second connecting piece and the rod body are integrated to form the simulation sonar probe, and when the sonar needs to pass through a relatively thin wellbore to enter the deep underground to measure the volume, depth and other parameters of the cavity, the simulation probe can be placed in the wellbore first, and the simulation probe can pass through the deep part of the wellbore, and the real scene of the sonar passing through the wellbore can be simulated. When the simulation probe is stuck in the wellbore and cannot move up and down, the connecting line breaks earlier than the cable, thereby protecting the cable and avoiding damage to the cable. When the simulation probe can smoothly pass through the wellbore, the simulation probe can be taken out, and then the sonar can be placed in the wellbore, and the measurement of the salt cavern can be realized. However, when the simulation probe is stuck in the wellbore, the connecting line can be pulled off by force, and the cable can be taken out, thereby avoiding the problem of the sonar falling due to unknown wellbore conditions.

[0030] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application.

When it is necessary to use sonar to penetrate a narrow well shaft to enter the deep underground to measure parameters such as the volume and depth of the cavity, the simulated probe can be placed into the well shaft first and allowed to travel deep into the well shaft, thus simulating the scenario of real sonar traveling in the well shaft. By setting the strength of the connecting line 2 to be less than that of the cable 6, when the simulated probe gets stuck or trapped in the well shaft and cannot move up or down, the connecting line 2 will break before the cable 6, thus protecting the cable 6 and preventing damage to it. When the simulated probe can travel smoothly in the well shaft, the simulated probe can be removed, and then the sonar can be placed into the well shaft to achieve the measurement of the salt cavern. However, if the simulated probe gets stuck inside the well, force can be applied to break the connecting wire 2 and remove the cable, thus avoiding the problem of the sonar falling due to the unknown condition of the well.
