[0002] Borehole television technology is a test method for detecting the lithology and structural distribution of the inner wall of the borehole. It uses plane reflection to observe the borehole wall image, reflecting the borehole wall structure, the degree of fracture development, and other geological phenomena in the well.
[0003] Borehole TV test hole wall cleaning is an important step to ensure the test quality. The selection of cleaning fluid should be determined based on the water quality, mud quality and other possible contaminants in the borehole.

[0004] A Chinese invention patent with announcement number CN104989299A discloses a drilling TV test hole wall cleaning device. By arranging evenly distributed water spray holes on the main cylinder, water enters the main cylinder from the water inlet.

DETAILED DESCRIPTION
[0039] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.
[0040] Example 1: Please combine Figure 2-Figure 5The present embodiment is a drilling TV test hole wall cleaning device, a support frame 1, the support frame 1 is fixed to the ground; a winding mechanism, the winding mechanism contains a conveying pipe 3, one end of the conveying pipe 3 is connected to a liquid supply device for providing cleaning liquid; a cleaning mechanism, the cleaning mechanism includes a detachable upper shell 4 and a lower shell 5, wherein the upper shell 4 is fixedly connected to one end of the conveying pipe 3, and an auxiliary moving mechanism is arranged on the outer side of the lower shell 5 to facilitate the cleaning mechanism to move along the hole wall, the winding mechanism also includes a rotating wheel 2, the rotating wheel 2 is rotatably connected to the top of the support frame 1, and the rotating wheel 2 is slidably connected to the conveying pipe 3, and the conveying pipe 3 is axially arranged along the hole wall, specifically, the winding mechanism also includes a driving motor and a winding roller, and the rotating winding roller is used to realize the vertical movement of the upper shell 4 at the hole wall under the action of gravity and the rolling of the rotating wheel 2, and the liquid supply device includes a pump body, and the pump body conveys the cleaning liquid to the device through the conveying pipe 3, and cleans the hole wall.
[0041] The auxiliary moving mechanism includes a sleeve 10, which is fixedly connected to the outer walls of the upper shell 4 and the lower shell 5 respectively, and a circular plate 12 is connected to the sleeve 10 for relative horizontal sliding. A spring 11 is elastically connected between the circular plate 12 and the inner wall of the sleeve 10. The circular plate 12 is located outside the sleeve 10 and is fixedly connected to a sleeve block 13. The outer end of the sleeve block 13 is rotatably connected to a wheel 14, and the wheel 14 is in sliding contact with the hole wall. Specifically, the moving direction of the wheel 14 is consistent with the extension direction of the hole wall. When the device is active in the hole wall, it can be stably slidably contacted with the hole wall under the action of multiple elastically retractable wheels 14, thereby ensuring that the device is stably centered, avoiding collision with the hole wall during movement of the device, and further protecting the device body.
[0042] The implementation principle of a drilling TV test hole wall cleaning device in the embodiment of the present application is:
[0043] After the entire conveying pipe 3 is sleeved on the rotating wheel 2, ensure that the conveying pipe 3 is coaxial with the hole wall under the action of gravity, use the winding equipment to lower the equipment into the hole wall in an orderly manner, and use the conveying equipment to convey the corresponding required cleaning liquid into the equipment through the conveying pipe 3 to clean the hole wall.
[0044] As the equipment is lowered, under the action of multiple sets of positioning components, multiple sets of springs 11 can be used to push the circular plate 12 so that multiple sets of wheels 14 can abut against the hole wall, thereby ensuring that the equipment is centered and stable when it is displaced in the hole wall, so that the equipment can ensure that the cleaning liquid is transported more evenly and stably during the cleaning operation, ensuring the cleaning efficiency and reducing the erosion of the hole wall.
[0045] Example 2: Combination Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig. 9Based on Example 1, this embodiment is further improved in that:
[0046] The infusion pipeline includes a detachable upper tube 8 and a lower tube 9, wherein the upper tube 8 is composed of a thin tube at the top section and a thick tube at the bottom section, and the lower tube 9 is composed of a thick tube at the top section and a thin tube at the bottom section. The upper tube 8 and the lower tube 9 are two identical components symmetrically arranged. The top end of the upper tube 8 is fixedly connected to the delivery tube 3, and an internal positioning block 7 is fixedly connected at the connection between the upper tube 8 and the lower tube 9.
[0047] A positioning plate 16 is fixedly connected to the inner wall of the upper tube 8, a rotating rod 15 is rotatably connected to the middle of the positioning plate 16, a rotating blade 17 is fixedly connected to the upper outer wall of the rotating rod 15, a positioning plate 2 18 is rotatably connected to the lower outer wall of the rotating rod 15, sliding blocks 28 are symmetrically fixedly connected to both sides of the bottom end of the rotating rod 15, and the positioning plate 2 18 is fixedly connected to the lower part of the inner wall of the lower tube 9, specifically, located on the inner wall of the thin tube section of the lower tube 9.
[0048] The bottom end of the lower tube 9 is slidably connected to the cavity 19, and the bottom end of the cavity 19 is circumferentially connected to a plurality of nozzles 22, and the plurality of nozzles 22 are all connected to the cavity 19. Specifically, the nozzle 22 is composed of an outer sleeve, an inner sleeve and an internal hose, wherein the outer sleeve and the inner sleeve slide horizontally relative to each other, the inner sleeve is rotatably connected to the outer wall of the cavity 19, and the internal hose is connected to the inside of the cavity 19 to facilitate the transportation of the cleaning liquid. When the nozzle 22 is adapted to the angle change caused by the reciprocating vertical displacement of the cavity 19, the nozzle 22 can adapt to the change in displacement with the cavity 19 through the outer sleeve and the inner sleeve that are telescopically slidably connected, ensuring that the nozzle 22 and the cavity 19 can perform cleaning operations normally. A center tube 26 is fixedly connected to the middle of the bottom end of the cavity 19, and vertical slide grooves 27 are symmetrically provided in the center tube 26, and the vertical slide grooves 27 are vertically slidably connected to the slider 28.
[0049] The infusion pipeline also includes a spiral guide groove 20 arranged in the middle of the inner wall of the lower shell 5, and a slide rod 21 is cyclically slidably connected in the guide groove 20. The other side of the slide rod 21 is fixed to the upper outer wall of the cavity 19. A sealing rubber ring is provided at the sliding position between the cavity 19 and the outer wall of the lower tube 9. Specifically, the guide groove 20 is a spirally closed guide slide groove. Further, the connection operation principle of the guide groove 20 and the slide rod 21 is based on a cylindrical cam mechanism, which is a mechanical device that can convert rotational motion into linear reciprocating motion. When the cavity 19 drives the slide rod 21 to rotate, the guide groove 20 in the lower shell 5 will contact the slide rod 21 and push the slide rod 21 to reciprocate in a linear direction. For details, please refer to Figure 8, the solid arrow is a schematic diagram of the sliding direction of the slide bar 21 along the contour of the guide slot 20, and the dotted arrow is a schematic diagram of the sliding direction of the slide bar 21 along the contour of the guide slot 20, and finally realizes the vertical reciprocating displacement of the slide bar 21; specifically, the rotation direction of the slide bar 21 rotates in a single direction along the guide slot 20, and will follow the contour of the specially designed spiral closed guide slot 20, and after a one-way vertical displacement to the top, the slide bar 21 will drive the cavity 19 to convert the vertical displacement direction to achieve reciprocating motion. The principle of this motion conversion mainly depends on the design of the contour of the slide bar 21 and the guide slot 20. Through reasonable contour design, the precise reciprocating motion of the follower within a specific stroke can be achieved. Specifically, when the rotating rod 15 rotates with the rotating blade 17, the vertical slide groove 27 and the slider 28 can drive the central tube 26 and the cavity 19 to rotate, and with the sliding connection between the guide slot 20 and the slide bar 21, the entire cavity 19 can be rotated circumferentially and vertically reciprocated.
[0050] The bottom end of the lower shell 5 is rotatably connected to a bottom rotating block 25, and a plurality of sleeve plates 24 are evenly fixedly connected to the bottom end of the bottom rotating block 25 corresponding to the number of nozzles 22. Rotating blocks 23 are rotatably connected inside the plurality of sleeve plates 24, and a plurality of groups of rotating blocks 23 are fixedly connected to both sides of the nozzles 22. Specifically, the rotating blocks 23 are fixedly connected to the outer sleeve.
[0051] The infusion pipeline also includes a positioning plate three 29, which is fixedly connected to the bottom of the inner wall of the lower tube 9, and the middle part of the positioning plate three 29 is rotatably connected to the rotating rod 15. The bottom ends of both sides of the positioning plate three 29 are fixedly connected with inclined brushes 30. The inclination angle of the brush 30 is consistent with that of the lower outer wall of the cavity 19, and there is a movable gap between the bottom end of the brush 30 and the bottom of the inner wall of the cavity 19. The middle part of the brush 30 is a plastic rod body, which can adapt to fit the cavity 19 for cleaning the inside.
[0052] The cleaning mechanism also includes an external positioning block 6, which is fixed at the connection between the upper shell 4 and the lower shell 5, and the inner wall of the external positioning block 6 is fixed to the internal positioning block 7. The external positioning block 6 is fixed to the upper shell 4 and the lower shell 5 by screws, the internal positioning block 7 is fixed to the upper tube 8 and the lower tube 9 by screws, and the middle part of the internal positioning block 7 and the external positioning block 6 are also fixed by screws for easy installation and disassembly. The above-mentioned connection method includes but is not limited to the method of screw disassembly.
[0053] The implementation principle of a drilling TV test hole wall cleaning device in the embodiment of the present application is:
[0054] When the conveying device uses the conveying pipe 3 to convey the cleaning liquid into the upper tube 8 and the lower tube 9, the cleaning liquid will first contact the rotating rod 15 and the rotating blade 17. Under the impact force of the conveying, the rotating blade 17 will be pushed to drive the rotating rod 15 to rotate under the rotation connection between the positioning plate 16 and the positioning plate 2 18, so that the vertical slide groove 27 and the slider 28 at the bottom of the rotating rod 15 can be used to slide vertically, and finally drive the entire cavity 19 to rotate, and the sliding rod 21 and the guide slot 20 can be moved forward and backward. Under the complex sliding connection, the cavity 19 is driven to move vertically back and forth at the bottom end of the lower tube 9, and can also perform a synchronous rotational compound motion. The multiple nozzles 22 connected to the cavity 19 at the bottom cooperate with the rotation of the rotating block 23, and under the fixed connection between the sleeve plate 24 and the bottom rotating block 25, the bottom rotating block 25 can be driven to rotate synchronously at the bottom end of the lower shell 5, so as to realize the reciprocating change of the external spraying angle of the nozzle 22. At the same time, the nozzle 22 can also rotate synchronously with the bottom rotating block 25, so as to further improve the cleaning angle and cleaning range of the equipment, and make the cleaning more uniform.
[0055] The positioning plate 3 29 fixed at the bottom end of the lower tube 9 and the brush 30 perform a composite motion in the cavity 19, which can clean and scrape the connecting port between the cavity 19 and the nozzle 22, avoiding clogging of the nozzle 22 as the cleaning time increases, and ensuring that the nozzle 22 can perform effective spray cleaning.
[0056] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
