Description

Technical Field

[0001] This invention relates to the field of oil and gas field maintenance operation technology, and more specifically, to a positionable and adjustable well test pulley. Background Technology

[0002] Well testing is a technology that uses seepage theory as a basis and various well testing equipment and instruments to monitor the dynamic and static states of oil, gas and water wells. The obtained well test data is used to interpret and analyze the physical properties of oil and gas reservoirs and the production capacity of oil, gas and water wells, providing a reliable basis for the exploration and development of oil and gas fields.

[0003] However, during the use of well testing equipment, due to the lack of existing technology in terms of the structure that can quickly expand the volume of the top pulley to improve the rotation effect and lifting speed, when the top pulley group needs to quickly remove the detection equipment from the well, it can only be passively removed by the rotation speed of the pulley itself. The whole process cannot be accelerated, and the pulley requires a long rotation cycle, which affects the progress of the test construction.

[0004] To address the aforementioned technical shortcomings, a solution is provided. Summary of the Invention

[0009] In a preferred embodiment, a common strip plate is fixedly installed on one side of a plurality of extrusion plates. The common strip plate is arranged vertically and in a ring shape. A rotating ring is threadedly connected to the inner wall of the common strip plate. The rotating ring is rotatably installed on the outer wall of a pulley. A turntable is fixedly installed on the outer wall of the rotating ring.

[0010] In a preferred embodiment, the locking mechanism includes a plurality of slots formed on the outer wall of the pulley, the plurality of slots being arranged in a one-to-one correspondence with a plurality of top support blocks, and extension protrusions being slidably installed on the inner walls of the plurality of slots. The extension protrusions are fixedly installed on the outer walls of the top support blocks and penetrate the outer wall of the pulley.

[0011] In a preferred embodiment, an airbag tube is fixedly installed on the top of the plurality of top support blocks. The horizontal height of the top of the airbag tube is higher than the horizontal height of the top of the top support block. One side of the airbag tube is connected to an air guide tube, and one side of the air guide tube is connected to an air chamber. The air chamber is opened on the inner wall of the extension protrusion. A piston plate is slidably installed on the inner wall of the air chamber. The outer wall of the piston plate is in contact with the inner wall of the air chamber. A retaining strip is fixedly installed on the top of the piston plate. The retaining strip passes through the top of the extension protrusion and is arc-shaped.

[0012] In a preferred embodiment, the support mechanism includes a push plate disposed on one side of the bottom of the same belt plate. The push plate is vertically disposed, and the outer wall of the push plate is in contact with the outer wall of the same belt plate.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Existing technologies lack structures capable of rapidly expanding the volume of the top pulley to improve rotation efficiency and retrieval speed. This means that when the top pulley assembly needs to quickly remove the detection equipment from the well, it can only passively rely on the pulley's own rotation speed, making it impossible to increase speed throughout the process. The long rotation cycle of the pulley also impacts the testing and construction schedule. To address this issue, the following technical solution is proposed: Refer to the instruction manual appendix Figures 1-7 A type of positionable and adjustable well test pulley, such as Figure 1 and Figure 2 As shown, the device includes a support base 1, a rotating shaft 2 at the top of the support base 1, a pulley 3 fixedly mounted on the outer wall of the rotating shaft 2, a top support mechanism 4 and a locking mechanism 5 on the outer wall of the pulley 3, the top support mechanism 4 can compress and extend multiple support structures on the outer wall of the pulley 3 to expand the outer wall range of the pulley 3, and the locking mechanism 5 can restrict the space of the pulley 3 during use to prevent it from falling off, and a support mechanism 6 is provided on both sides of the bottom of the support base 1, the support mechanism 6 can expand the support range on both sides of the bottom of the pulley 3.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, the top support mechanism 4 includes multiple limiting grooves 41 formed on the outer wall of the pulley 3. The multiple limiting grooves 41 are arranged in a ring at equal intervals. Top support blocks 42 are slidably installed on the inner wall of the multiple limiting grooves 41. The tops of the multiple top support blocks 42 are arc-shaped. The outer walls of the multiple top support blocks 42 are in contact with the outer wall of the pulley 3. A retaining plate 43 is fixedly installed on one side of the outer wall of the multiple top support blocks 42. A leveling spring 44 is fixedly installed on the outer wall of the retaining plate 43. The leveling spring 44 is fixedly installed on the inner wall of the pulley 3. Multiple top support blocks 42 move upward synchronously, driving the clamping plate 43 and compressing the leveling spring 44. Thus, the multiple top support blocks 42 together expand the outer ring volume of the pulley 3 by moving upward.

[0026] like Figure 4 and Figure 5 As shown, the bottoms of the multiple top support blocks 42 are inclined, and an extrusion plate 45 is provided on one side of the bottom of the multiple top support blocks 42. The multiple extrusion plates 45 are slidably installed on the outer wall of the pulley 3, and the tops of the multiple extrusion plates 45 are in contact with the bottoms of the top support blocks 42. Multiple extrusion plates 45 move forward synchronously to press the bottom of multiple top support blocks 42, and the multiple top support blocks 42 move under force.

[0027] like Figure 4 and Figure 5As shown, a common strip plate 46 is fixedly installed on one side of multiple extrusion plates 45. The common strip plate 46 is set in a vertical state and is arranged in a ring. A rotating ring 47 is threadedly connected to the inner wall of the common strip plate 46. The rotating ring 47 is rotatably installed on the outer wall of the pulley 3. A turntable 48 is fixedly installed on the outer wall of the rotating ring 47. When the turntable 48 rotates, the rotating ring 47 rotates synchronously. The threads on the outer wall of the rotating ring 47 cause the belt plate 46 to move, and the belt plate 46 drives multiple extrusion plates 45 to move synchronously.

[0028] like Figure 3 and Figure 6 As shown, the locking mechanism 5 includes multiple slots 51 formed on the outer wall of the pulley 3. The multiple slots 51 are arranged in a one-to-one correspondence with multiple top support blocks 42. The inner walls of the multiple slots 51 are slidably fitted with extension protrusions 52. The extension protrusions 52 are fixedly installed on the outer wall of the top support blocks 42 and penetrate the outer wall of the pulley 3. The upward movement of the top support block 42 can drive the extension protrusion 52 to extend synchronously, forming a protective structure.

[0029] like Figure 6 As shown, airbag tubes 53 are fixedly installed on the top of multiple support blocks 42. The horizontal height of the top of the airbag tube 53 is higher than the horizontal height of the top of the support block 42. One side of the airbag tube 53 is connected to an air guide tube 54, and one side of the air guide tube 54 is connected to an air chamber 55. The air chamber 55 is opened on the inner wall of the extension protrusion 52. A piston plate 56 is slidably installed on the inner wall of the air chamber 55. The outer wall of the piston plate 56 is in contact with the inner wall of the air chamber 55. A retaining strip 57 is fixedly installed on the top of the piston plate 56. The retaining strip 57 passes through the top of the extension protrusion 52 and is arc-shaped. When the pulley 3 is in use, the air bladder tube 53 on its surface is squeezed and compressed air enters the air guide tube 54. The gas that enters the air chamber 55 through the air guide tube 54 pushes up the piston plate 56 and the locking strip 57. The locking strip 57 extends out and locks the top area of ​​the top support block 42 in an arc shape.

[0030] like Figure 7 As shown, the support mechanism 6 includes a push plate 61 disposed on one side of the bottom of the same belt plate 46. The push plate 61 is disposed vertically, and the outer wall of the push plate 61 is in contact with the outer wall of the same belt plate 46. A push block 62 is fixedly installed on one side of the push plate 61, and the push block 62 is slidably installed on the outer wall of the support base 1. When the belt plate 46 moves, it pushes the push plate 61 synchronously, and the push plate 61 drives the push block 62 to move synchronously.

[0031] like Figure 7As shown, one side of the push block 62 is triangularly arranged, and the outer walls of both sides of the push block 62 are respectively provided with brackets 63. The two brackets 63 are slidably installed on the outer wall of the support base 1. The outer walls of the two brackets 63 are in contact with the outer wall of the push block 62. The outer walls of the two brackets 63 are fixedly installed with a tension spring 64. Roller wheels 65 are rotatably installed on one side of the two brackets 63. The two roller wheels 65 are symmetrically arranged. The outer walls of the two roller wheels 65 are mutually coordinated with the two sides of the pulley 3. The pusher 62 moves and squeezes open the brackets 63 on both sides through the triangular structure. The two brackets 63 drive the rollers 65 to extend and stretch the tension springs 64 respectively.

[0032] In practical implementation, the turntable 48 rotates synchronously with the rotating ring 47. The threads on the outer wall of the rotating ring 47 cause the belt plate 46 to move. The belt plate 46 drives multiple extrusion plates 45 to move forward synchronously and squeeze the bottom of multiple top support blocks 42. The multiple top support blocks 42 move under force and move upward synchronously, driving the clamping plate 43 and compressing the leveling spring 44. The multiple top support blocks 42 expand the outer ring volume of the pulley 3 by moving upward. At the same time, the belt plate 46 moves synchronously and pushes the push plate 61. The push plate 61 drives the push block 62 to move synchronously. The movement of the push block 62 squeezes and opens the belt brackets 63 on both sides through the triangular structure. The two belt brackets 63 drive the rollers 65 to extend, so that the support area on both sides of the bottom of the pulley 3 expands synchronously. Thus, the rotation diameter of the pulley 3 increases, which enables it to quickly pick up the detection equipment from the well and effectively speed up the process, reduce the required rotation cycle, and avoid test construction progress time. As the outer wall of the pulley 3 is expanded by multiple top support blocks 42, the protective surface of its surface is reduced. The upward movement of the top support blocks 42 can drive the extension protrusions 52 to extend synchronously, forming a protective structure. When used on the pulley 3, the air bladder tube 53 on its surface is squeezed and compressed air enters the air guide tube 54. The gas that enters the air chamber 55 through the air guide tube 54 lifts the piston plate 56 and the locking strip 57. The locking strip 57 extends out and is arc-shaped to lock the top area of ​​the top support block 42.
