Description

Technical Field

[0001] This utility model relates to the field of logging instrument technology, and in particular to a tool for cleaning mud from logging cables. Background Technology

[0002] Well logging cables are used in well logging operations in various radioactive and coalfield boreholes, as well as in water conservancy and hydrological boreholes. They serve as the connection line between the surface system and underground instruments, acting as a load-bearing link and transmitting measurement data. Their main functions are to withstand tensile force, provide power to the system, transmit signals, and control depth. The purpose of well logging cables is to detect various downhole parameters. The crucial role of well logging cables is to transmit various downhole instruments, relay signals between the surface control system and downhole instruments, and obtain depth and location information from the downhole environment.

[0003] The cable used to connect the logging instrument to the wellhead needs to be pulled out of the well after the exploration is completed. During the extraction process, mud will stick to the cable and adhere to the winch, affecting subsequent collection and reuse. The current method for dealing with the mud on the cable is to manually wipe it off with a cloth. This operation is somewhat dangerous and laborious. Therefore, a logging cable mud cleaning tool is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that manually wiping away mud with a rag in the existing technology is dangerous and laborious, and to propose a mud cleaning tool for logging cables.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A well logging cable mud cleaning tool includes two sponge blocks set inside the port of a hydraulic pipe wringer. The hydraulic pipe wringer is set at the wellhead of the exploration well. A first Velcro fastener is provided between the inner wall of the hydraulic pipe wringer and the sponge blocks. The first Velcro fastener includes a first rough surface pasted on the inner wall of the hydraulic pipe wringer and a first smooth surface pasted on the outer surface of the sponge blocks.

[0007] A second Velcro fastener is provided between the two sponge blocks. The second Velcro fastener includes a second textured surface fixed to one of the sponge blocks and a second smooth surface fixed to the other sponge block. The cable passes between the two sponge blocks.

[0008] Preferably, the top of the hydraulic pipe tightening machine is also provided with a limiting structure, which includes a horizontal plate, clamping blocks at both ends of the horizontal plate, and an arc-shaped pressure plate at the bottom of the horizontal plate. The arc-shaped pressure plate is bonded to the sponge block, and a top rod is internally threaded to the clamping block.

[0009] Preferably, the horizontal plate has a rectangular hole inside, and a lead screw is rotatably connected to both ends of the rectangular hole. The clamping block is threaded to the outer surface of the lead screw.

[0010] Preferably, the horizontal plate has a circular hole inside, through which the cable passes.

[0011] Preferably, the hydraulic pipe wringer is model NY-3A.

[0012] Preferably, the two sponge blocks are semi-circular in shape.

[0013] Preferably, a support rod is fixedly connected to the upper surface of the horizontal plate, a water pipe is snapped onto the top of the support rod, a valve is installed on the water pipe, and one end of the water pipe is connected to the water inlet of the water tank.

[0014] Preferably, the water outlet of the water pipe is located directly above the point where the sponge block contacts the cable.

[0015] Compared with the prior art, this utility model provides a logging cable mud cleaning tool, which has the following beneficial effects:

[0016] 1. This utility model, through the coordinated arrangement of a detection well, a hydraulic pipe-tightening machine, a sponge block, a first smooth surface, a cable, a second rough surface, a second smooth surface, a first rough surface, and a limiting structure, firstly releases the cable from the winch into the detection well. After detection, the first smooth surface and the first rough surface are respectively adhered to the outer surface of the sponge block and the inner wall of the hydraulic pipe-tightening machine. The two sponge blocks are bent towards each other, so that the second rough surface and the second smooth surface on the two sponge blocks adhere to each other, wrapping the cable. During the process of lifting the cable upward, the two sponge blocks brush off the mud on the cable. The sponge blocks serve two purposes: firstly, to clean the mud off the cable, and secondly, to protect the cable, preventing wear between the cable and the port of the hydraulic pipe-tightening machine when the cable is lifted upward, thus protecting the cable.

[0017] 2. This utility model, through the cooperative arrangement of a detection well, an arc-shaped pressure plate, a hydraulic pipe tightening machine, sponge blocks, a first smooth surface, a horizontal plate, clamping blocks, a top rod, a rectangular hole, a screw rod, a cable, a second rough surface, a second smooth surface, a first rough surface, a round hole, a support rod, and a water pipe, features a horizontal plate composed of two symmetrical grooved flat plates fixed with bolts. Clamping blocks at both ends of the horizontal plate are held at the top of the hydraulic pipe tightening machine. Rotating the top rod fixes the horizontal plate and clamping blocks at the top of the hydraulic pipe tightening machine. The arc-shaped pressure plate is positioned directly above the two sponge blocks, ensuring their stability when the cable is pulled upwards. A limiting structure further restricts the position of the sponge blocks, preventing them from moving upwards with the cable. Rotating the screw allows the clamping blocks to move horizontally within the rectangular hole, changing the distance between the two clamping blocks to accommodate different models of hydraulic pipe tightening machines. A water tank is placed near the detection well, and the gravity of the water inside the tank is used to pour water onto the sponge blocks, increasing the lubrication between the sponge blocks and the cable, and improving the performance of washing away cable sludge.

The matting arrangement of the rough surface 12, the second smooth surface 13, and the first rough surface 14 is as follows: First, the cable is released from the winch into the detection well. After the detection is completed, the first smooth surface 5 and the first rough surface 14 are respectively attached to the outer surface of the sponge block 4 and the inner wall of the hydraulic pipe wringer 3. The two sponge blocks 4 are bent towards each other, so that the second rough surface 12 and the second smooth surface 13 on the two sponge blocks 4 adhere to each other, wrapping the cable 11. During the process of lifting the cable 11 upward, the two sponge blocks 4 brush off the mud on the cable 11. The sponge blocks 4 serve two purposes: firstly, to clean the mud on the cable 11, and secondly, to protect the cable, preventing wear between the cable 11 and the port of the hydraulic pipe wringer 3 when the cable is lifted upward, thus protecting the cable.

The two sponge blocks 4 are bent towards each other, so that the second rough surface 12 and the second smooth surface 13 on the two sponge blocks 4 adhere to each other, wrapping the cable 11. During the upward lifting of the cable 11, the two sponge blocks 4 brush off the mud on the cable 11. The sponge blocks 4 serve two purposes: cleaning the mud on the cable 11 and protecting the cable, preventing wear between the cable 11 and the end of the hydraulic pipe wrench 3 when the cable is lifted.
