Description

Technical Field

[0001] This utility model relates to the field of oil well debris collection technology, specifically a debris collection device for oil well downhole operations and overhauls. Background Technology

[0002] An oil well is a well drilled for the purpose of extracting oil and natural gas. In the process of oil and gas exploration and development, any well drilled to obtain oil and gas from underground is collectively referred to as an oil well. During oil well downhole operations and workovers, workers often use nets or scoops to retrieve sheet-like or block-like parts that have fallen off the equipment, including packer rubber. These rubber pieces suspended inside the wellbore can cause obstruction during sand flushing and well cleaning, which greatly affects the progress of oil well downhole operations and workovers.

[0003] When using existing debris collection devices for downhole workover operations, conventional nets or scoops, due to their fixed size and lack of telescopic expansion capabilities, are obstructed by floating debris during their descent to the bottom of the well.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-8As shown, a debris collection device for oil well downhole workover includes a base plate 1. Multiple omnidirectional brake wheels 2 are symmetrically installed along the bottom edge of the base plate 1. Two side plates 3 are symmetrically arranged at the top of one end of the base plate 1, with their bottoms connected to the base plate 1. A winding roller 4 is provided between the side plates 3, rotatably connected to both ends of the side plates 3. An opening 9 is provided at the other end of the base plate 1.

A first controller 12 is fixedly installed on the top of one side of the push-pull handle 11. Using the omnidirectional brake wheels 2 and the push-pull handle 11, the opening 9 at one end of the base plate 1 can be easily aligned with the oil well, and then... The first controller 12 facilitates subsequent object collection. It should be noted that the first controller 12 can be a control panel with touchscreen operation. The first controller 12; a lifting column 14 is located below the opening 9, and a support plate 20 is located below the lifting column 14. It also includes: a drive assembly 5 located on one side of the side plate 3 to provide rotational force to the winding roller 4; a lifting rope 6 is located on the outside of the winding roller 4; a mounting shell 15 is fixedly connected to the top of the lifting column 14; a second controller 16 is fixedly installed at the bottom of the inner cavity of the mounting shell 15. It should be noted that the second controller 16 can be a microcontroller or a motherboard. One end of the lifting rope 6 is connected to the mounting shell 15. By setting the drive assembly 5, the winding roller 4 can be rotated. The cable body rotates in either the forward or reverse direction to perform unwinding or rewinding operations, facilitating the entry of the lifting column 14 at one end of the cable 6 into the oil well for debris collection. A pulley assembly 13 is provided on one side of the cable 6 to guide the cable 6, ensuring the lifting column 14 smoothly enters the oil well and reducing the likelihood of it hitting the well wall. A battery 8 is located below the cable 6 and is fixedly mounted on the top of the base plate 1. Both the drive assembly 5 and the battery 8 are connected to the terminals of the first controller 12 via data cables. A power transmission assembly 7 is located on the outside of the cable 6 to provide power to the second controller 16. This power transmission assembly 7 allows the lifting column to... After the entire assembly 14 enters the oil well, it provides power to the second controller 16. Multiple U-shaped seats 23 are symmetrically installed on the outer side of the support plate 20. Strip rods 24 are rotatably connected inside the U-shaped seats 23. A net 25 is positioned between adjacent strip rods 24, and the net 25 is connected to the strip rods 24 on both sides. A transmission assembly 26 is provided at the bottom of the lifting column 14, allowing for quick adjustment of the tilt angle of the strip rods 24. By setting the transmission assembly 26, the strip rods 24 can swing around the U-shaped seats 23, thus keeping the net 25 in a retracted state during entry into the oil well, reducing the chance of the net 25 being obstructed by floating objects. The transmission assembly 26 is connected to the terminal of the second controller 16 via a data cable.

[0028] The drive assembly 5 includes a support plate 51 fixed to one side of the side plate 3. A drive motor 52 is fixedly mounted on the top of the support plate 51.

[0029] Pulley assembly 13 includes a guide pulley 131 disposed on one side of winding roller 4. L-shaped plates 132 are provided on both sides of the guide pulley 131. One end of each L-shaped plate 132 is connected to the side plate 3. The guide pulley 131 is rotatably connected to both ends of the L-shaped plates 132. Figure 1 , Figure 2 As shown, by setting the guide pulley 131, the lifting column 14 can be smoothly entered into the oil well, thus reducing the probability of the lifting column 14 touching the wall.

[0030] A counterweight 22 is fixedly connected to the center of the bottom surface of the support plate 20. The counterweight 22 has an inverted conical design. Figure 5 As shown, the counterweight 22 with its inverted conical design can play an auxiliary role in the process of the lifting column 14 falling into the oil well.

[0031] The power transmission assembly 7 includes a first conductor 71 fixed to the outside of the suspension rope 6, a conductive slip ring 72 provided on the outside of one end of the winding roller 4, the stator of the conductive slip ring 72 connected to the side plate 3, the rotor of the conductive slip ring 72 connected to the winding roller 4, one end of the first conductor 71 passing through the winding roller 4 and connected to the rotor terminal of the conductive slip ring 72, the other end of the first conductor 71 connected to the terminal of the second controller 16, a second conductor 73 connected to the stator terminal of the conductive slip ring 72, one end of the second conductor 73 connected to the output terminal of the battery 8, such as... Figure 1 , Figure 3 and Figure 4 As shown, the first conductor 71, which forms a single rope with the hoisting rope 6, can be lowered into the oil well along with the lifting column 14. Then, through the second conductor 73 and the first conductor 71 in sequence, the battery 8 can supply power to the second controller 16, thus realizing long-distance power transmission, which is beneficial for the collection of objects falling into the oil well. Furthermore, by setting a conductive slip ring 72, the first conductor 71 can rotate together with the hoisting rope 6 as it is raised and lowered, thus avoiding damage to the first conductor 71 due to excessive twisting and preventing power interruption.

[0032] The transmission assembly 26 includes an electric push rod 261 fixed inside the lifting column 14. A movable block 262 is fixedly connected to the bottom end of the electric push rod 261. A limiting plate 268, corresponding to the number of strip rods 24, is provided on the outer side of the movable block 262. The limiting plates 268 are connected to the lifting column 14 and the support plate 20 respectively. A connecting rod 263 is provided between adjacent limiting plates 268. One end of the connecting rod 263 is connected to the movable block 262, and the other end of the connecting rod 263 has a limiting groove 264. A slider 265 is fixedly connected inside the limiting groove 264. A strip plate 266 is vertically installed on one side of the bottom end of the strip rod 24. A groove 267, corresponding to the slider 265, is provided on the outer side of the strip plate 266. The slider 265 is located inside the groove 267. The electric push rod 261 is connected to the terminal of the second controller 16 via a data cable. Figure 6 , Figure 7 and Figure 8 As shown, during the process of the lifting column 14 entering the oil well, the electric push rod 261 can drive the moving block 262 and connecting rod 263 to move upward. With the cooperation of the slider 265 inside the limiting groove 264 and the sliding groove 267 outside the strip plate 266, multiple strip rods 24 can swing inward at the same time, so that the net 25 is in a contracted state, thus reducing the probability of the net 25 being obstructed by floating objects. When the lifting column 14 reaches the bottom of the oil well to perform the falling object collection work, the electric push rod 261 can drive the moving block 262 and connecting rod 263 to move downward, so that multiple strip rods 24 can swing outward at the same time, so that the net 25 is in an expanded state. The net 25 in the expanded state forms a funnel shape, which can collect floating objects along the way during the ascent, thus realizing the falling object collection work.

[0033] The electric push rod 261 has a waterproof telescopic sleeve 21 on one side. The waterproof telescopic sleeve 21 is connected to the lifting column 14 and the support plate 20 respectively. Figure 6 , Figure 7 and Figure 8 As shown, by setting the waterproof telescopic sleeve 21, it is possible to prevent dirt inside the oil well from adhering to the piston column of the electric push rod 261, thus providing a clean and sealed environment for the electric push rod 261 and improving the working stability of the transmission assembly 26.

[0034] A mounting base 17 is vertically installed on one side of the L-shaped rod 10. A first wireless transceiver 18 is fixedly connected to the bottom of the mounting base 17. The first wireless transceiver 18 is connected to the terminal of the first controller 12 via a data cable. A second wireless transceiver 19 is fixedly connected to one side of the mounting housing 15. The second wireless transceiver 19 is connected to the terminal of the second controller 16 via a data cable. Figure 2 , Figure 8As shown, the first wireless transceiver 18 can transmit the command issued by the first controller 12 to the second wireless transceiver 19 located at the bottom of the oil well in the form of a signal. The second wireless transceiver 19 then transmits the signal to the second controller 16. After receiving the command, the second controller 16 starts the transmission assembly 26 to perform the falling object collection work.

[0035] Working principle: First, the operator can drive the winding roller 4 to perform unwinding or rewinding operations through the drive component 5, which facilitates the entry of the lifting column 14 into the oil well for debris collection. During this process, the pulley component 13 can smoothly guide the lifting column 14 into the oil well, reducing the probability of the lifting column 14 hitting the well wall. The power transmission component 7 can provide power to the second controller 16 after the lifting column 14 has entered the oil well. Then, the transmission component 26 can keep the net 25 in a retracted state during the entry of the lifting column 14 into the oil well, thus reducing the probability of the net 25 being obstructed by floating objects. When the lifting column 14 reaches the bottom of the oil well to perform debris collection, the net 25 can be in an expanded state. The expanded net 25 can collect floating objects along the way, thus realizing the debris collection work.
