Description

Technical Field

[0001] This utility model relates to the field of oil and gas extraction technology, specifically to an oil well measuring tool. Background Technology

[0002] In oilfield production operations, the bottom-hole pressure-production curve plotted using the producing bottom-hole pressure and static bottom-hole pressure can indicate the highest achievable percentage of oil production for the well, thus revealing the well's extraction efficiency. This allows operators to determine whether more oil can be extracted from the well. Among the parameters measured, the well fluid level is one of the essential parameters for oil wells. Generally, there are two types of well fluid level measuring instruments operating on different principles: one is the ultrasonic well fluid level measuring instrument based on the ultrasonic echo principle, and the other is the electronic pressure well fluid level measuring instrument based on the principle that the well fluid level causes changes in bottom-hole pressure. A well measuring instrument, such as the oil well measuring tool disclosed in CN112065368A, includes a support, a winch, and a measuring instrument. The support is erected above the oil well; the winch is mounted on the support and is used to wind up and unwind the cable; the measuring instrument is connected to the winch via the cable. The measuring instrument includes a mounting plate, a sensor, an antenna, and a float. The density of the float is less than the density of the oil in the well. The sensor and antenna are mounted on the mounting plate, and the antenna is electrically connected to the sensor. An elastic rod is installed below the mounting plate, and the float is connected to the mounting plate via the elastic rod, which is electrically connected to the sensor.

[0003] Although the oil well measuring tool disclosed in CN112065368A uses a winch to lower the measuring instrument into the oil well and measure the oil level data, and transmits electromagnetic signals through an antenna to ensure the authenticity and accuracy of the measurement data, and does not require a dedicated cable, its simple structure and significant cost savings still have some shortcomings. During the lowering process, the measuring instrument may come into contact with or collide with the well wall, which could damage the instrument and affect the accuracy of the measurement data. Furthermore, when winding the cable, there is a possibility of the cable piling up in one place, which can easily lead to tangling. To address these issues, the inventors have proposed an oil well measuring tool to solve these problems. Utility Model Content

[0004] To address the issues of existing oil well measuring tools, such as the potential for direct collision or contact between the measuring instrument and the well wall, which can affect measurement accuracy, and the possibility of the measuring cable becoming entangled during cable winding, the purpose of this invention is to provide an oil well measuring tool.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an oil well measuring tool, including a frame, with indicator plates fixedly connected to both sides of the end face of the frame, a take-up and release wheel provided on one side of the top surface of the frame, a rope provided on the take-up and release wheel, a vertical frame provided on one side of the take-up and release wheel, and horizontal shafts rotatably connected to both sides of the side wall of the vertical frame, a synchronous pulley fixedly connected to the side wall of the horizontal shaft, a synchronous belt provided on the side wall of the synchronous pulley, and two horizontal shafts, one of which has a shaft end fixedly connected to... A first bevel gear is provided. A second motor is provided on one side of the upright frame. The output shaft of the second motor is fixedly connected to a second bevel gear. The second bevel gear corresponds to and meshes with the first bevel gear. A movable frame is provided on one side of the synchronous belt. A movable ring is fixedly connected to the bottom surface of the movable frame. The rope passes through the opening of the movable ring. A positioning ring is provided in the concave opening of the frame, which can be adjusted left and right. The rope also passes through the opening of the positioning ring. A measuring instrument is fixedly connected to the end of the rope. An arc-shaped plate is fixedly connected to the outer shell of the measuring instrument.

[0006] Preferably, a first motor is provided on one side of the take-up and release wheel, and a base is provided on the side wall of the first motor. The base is connected to the side wall of the frame. A support plate is rotatably connected to the axle of the take-up and release wheel, and the bottom surface of the support plate is fixedly connected to the top surface of the frame. The output shaft end of the first motor is fixedly connected to the axle end of the take-up and release wheel. The frame includes wheels and a push handle. In actual use, the push handle can be mounted on the frame, and the device can be moved by the wheels. When the first motor is started, the take-up and release wheel can rotate under the action of the output shaft of the first motor, thereby enabling the take-up and release of the rope. The support plate is used to support the rotation of the take-up and release wheel. A second motor is provided on the side wall of the second motor. A fixed frame is fixedly connected to the side wall of the upright frame. A guide opening is provided through the side wall of the movable ring. A first guide rod is fixedly connected to the side wall of the upright frame. The first guide rod is located inside the guide opening and is slidably connected to the guide opening. A second motor is installed through the fixed frame. When the second motor is started, the second bevel gear can rotate under the action of the output shaft of the second motor. Through the meshing of the second bevel gear and the first bevel gear, the horizontal shaft can be rotated, which in turn can rotate the synchronous pulley. The synchronous belt can drive the protrusion to move, which in turn can make the protrusion move in the slot of the movable frame to push the movable frame.

[0007] Preferably, a protrusion is fixedly connected to the outer wall of the synchronous belt, and a protruding post is fixedly connected to the side wall of the protrusion. The protruding post is located in the slot of the movable frame, and the protruding post cooperates with the slot of the movable frame. When the protruding post moves in the slot of the movable frame, the moving protruding post can apply force to the movable frame. With the cooperation of the first guide rod and the guide opening, the movable frame can be moved laterally back and forth, which can drive the movable ring to move. This allows the rope to be evenly wound on the take-up and unwinding wheels when the rope is being retrieved, avoiding the rope from piling up in one place during winding, which would make the next unwinding operation more troublesome. A second guide rod is fixedly connected to one side of the positioning ring, and a threaded cylinder is fixedly connected to the other side of the positioning ring. The second guide rod passes through the frame, and the second guide rod... The threaded cylinder is slidably connected to the frame. A screw is threadedly connected to the cylinder opening, passing through the frame and rotatably connected to it. A knob is fixedly connected to the side wall of the screw. When the frame is positioned, the line connecting the two indicator plates is aligned with the diameter of the wellhead. The knob can then be turned, causing the screw to rotate. Through the interaction between the screw and the threaded cylinder, and with the assistance of the second guide rod, the position of the movable ring can be finely adjusted to be located in the center of the wellhead. This ensures that when the cable is lowered into the well, the measuring instrument is centered within the wellbore. Furthermore, the arched plate prevents direct collision and contact between the measuring instrument and the well wall, protecting the measuring instrument and ensuring the accuracy of the measurement data.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: it can effectively ensure the accuracy of measurement data; when the measuring instrument is lowered into the well for measurement, it can be lowered to a central position in the wellbore; and the bow-shaped plate can further prevent the measuring instrument from directly colliding or sticking to the well wall, thus protecting the measuring instrument and ensuring the accuracy of the measurement data; and when the rope is wound up, it can be wound evenly on the take-up and unwinding wheels, avoiding the rope from piling up in one place during winding, which would make the next line laying operation more troublesome.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0015] Example: Figure 1-3 As shown, this utility model provides an oil well measuring tool, including a frame 1. Indicator plates 3 are fixedly connected to both ends of the frame 1. A take-up and release wheel 4 is provided on one side of the top surface of the frame 1, with a rope 7 attached to the take-up and release wheel 4. A stand 8 is provided on one side of the take-up and release wheel 4. Horizontal shafts 12 are rotatably connected to both sides of the side wall of the stand 8. Synchronous pulleys 10 are fixedly connected to the side wall of the horizontal shafts 12, and synchronous belts 11 are provided on the side wall of the synchronous pulleys 10. There are two horizontal shafts 12, one of which has a first bevel gear 13 fixedly connected to its shaft end. The stand 8... A second motor 14 is provided on one side, and a second bevel gear 15 is fixedly connected to the output shaft end of the second motor 14. The second bevel gear 15 corresponds to and meshes with the first bevel gear 13. A movable frame 16 is provided on one side of the synchronous belt 11, and a movable ring 20 is fixedly connected to the bottom surface of the movable frame 16. A rope 7 passes through the ring opening of the movable ring 20. A positioning ring 25 is provided in the concave opening of the frame 1, which can be adjusted left and right. The rope 7 also passes through the ring opening of the positioning ring 25. A measuring instrument 21 is fixedly connected to the end of the rope 7. An arc-shaped plate 22 is fixedly connected to the outer shell of the measuring instrument 21.

[0016] A first motor 5 is provided on one side of the take-up and release wheel 4. A base is provided on the side wall of the first motor 5. The base is connected to the side wall of the frame 1. A support plate 6 is rotatably connected to the wheel axle of the take-up and release wheel 4. The bottom surface of the support plate 6 is fixedly connected to the top surface of the frame 1. The output shaft end of the first motor 5 is fixedly connected to the shaft end of the wheel axle of the take-up and release wheel 4.

[0017] By adopting the above technical solution, the frame 1 includes wheels 2 and a push handle. In actual use, the push handle can be installed on the frame 1. The device can be moved by the wheels 2. The first motor 5 is started, and the take-up and release wheel 4 can rotate under the action of the output shaft of the first motor 5, thereby taking up and releasing the rope 7. The support plate 6 is used to support the rotation of the take-up and release wheel 4.

[0018] The second motor 14 has a fixed frame on its side wall, which is fixedly connected to the side wall of the upright frame 8. The side wall of the movable ring 20 has a guide opening 17 through it. The side wall of the upright frame 8 is fixedly connected to a first guide rod 9, which is located inside the guide opening 17 and is slidably connected to the guide opening 17.

[0019] By adopting the above technical solution, the second motor 14 is installed by a fixed frame. When the second motor 14 is started, the second bevel gear 15 can rotate under the action of the output shaft of the second motor 14. Through the meshing of the second bevel gear 15 and the first bevel gear 13, the horizontal shaft 12 can be rotated, which in turn can make the synchronous pulley 10 rotate. The synchronous belt 11 can drive the protrusion 18 to move, which in turn can make the protrusion 19 move in the slot of the movable frame 16 to push the movable frame 16.

[0020] A protrusion 18 is fixedly connected to the outer wall of the synchronous belt 11, and a protruding post 19 is fixedly connected to the side wall of the protrusion 18. The protruding post 19 is located in the slot of the movable frame 16, and the protruding post 19 and the slot of the movable frame 16 are matched.

[0021] By adopting the above technical solution, when the protruding column 19 moves in the slot of the movable frame 16, the moving protruding column 19 can apply force to the movable frame 16. With the cooperation of the first guide rod 9 and the guide port 17, the movable frame 16 can be moved laterally back and forth, which can drive the movable ring 20 to move. When the rope 7 is retrieved, the rope 7 can be evenly wound on the take-up and unwinding wheel 4, avoiding the rope 7 from piling up in one place during winding, which would make the next unwinding operation more troublesome.

[0022] A second guide rod 27 is fixedly connected to one side of the positioning ring 25, and a threaded cylinder 26 is fixedly connected to the other side of the positioning ring 25. The second guide rod 27 passes through the frame 1 and is slidably connected to the frame 1. A screw 23 is threadedly connected to the opening of the threaded cylinder 26. The screw 23 passes through the frame 1 and is rotatably connected to the frame 1.

[0023] By adopting the above technical solution, a knob 24 is fixedly connected to the side wall of the screw 23. When the frame 1 is placed, the line connecting the two indicator plates 3 is aligned with the diameter of the wellhead. Then, the knob 24 can be turned, and the screw 23 can rotate under the action of the knob 24. Through the cooperation between the screw 23 and the threaded cylinder 26, and under the action of the second guide rod 27, the position of the movable ring 20 can be finely adjusted so that the movable ring 20 is located in the middle of the wellhead. Thus, when the rope 7 is lowered into the well, the measuring instrument 21 can be positioned in the center of the wellbore. Furthermore, the bow-shaped plate 22 further prevents the measuring instrument 21 from directly colliding with or touching the well wall, thus protecting the measuring instrument and ensuring the accuracy of the measurement data. The measuring instrument 21 in this device is based on the same principle as the measuring instrument in publication number CN112065368A, and will not be described in detail here.

[0024] Working principle: When using this utility model, the device is moved to the wellhead of the oil well so that the line connecting the two indicator plates 3 coincides with the diameter of the wellhead. Then, the knob 24 can be turned, and the screw 23 can rotate under the action of the knob 24. Through the cooperation between the screw 23 and the threaded cylinder 26, and under the action of the second guide rod 27, the position of the movable ring 20 can be finely adjusted so that the movable ring 20 is located in the middle of the wellhead. Thus, when the rope 7 is lowered into the well, the measuring instrument 21 can be centered in the wellbore.

[0025] The line 7 on the take-up and release wheel 4 passes through the movable ring 20 and the positioning ring 25. The first motor 5 is started, so that the take-up and release wheel 4 performs the line release operation. Under the action of the weight of the measuring instrument 21 and the released line 7, the measuring instrument 21 can fall in the well. Because the movable ring 20 is adjusted to the middle position of the well opening, when the line 7 is lowered into the well, the measuring instrument 21 can fall in a centered position in the well, avoiding the situation of falling off course. Furthermore, the bow-shaped plate 22 further prevents the measuring instrument 21 from directly colliding or sticking to the well wall, so as to protect the measuring instrument and ensure the accuracy of the measurement data.

[0026] After the measurement is completed, when winding the rope 7, the first motor 5 is reversed so that the take-up and unwinding wheel 4 winds the rope 7. At the same time, the second motor 14 can be started. The second bevel gear 15 can rotate under the action of the output shaft of the second motor 14. Through the meshing of the second bevel gear 15 and the first bevel gear 13, the horizontal shaft 12 can be rotated, which in turn can rotate the synchronous pulley 10. The synchronous belt 11 can drive the protrusion 18 to move, which in turn can make the protrusion 19 move in the slot of the movable frame 16. The moving protrusion 19 can apply force to the movable frame 16. With the cooperation of the first guide rod 9 and the guide port 17, the movable frame 16 can be moved laterally back and forth, which can drive the movable ring 20 to move. When the rope 7 is retrieved, the rope 7 can be evenly wound on the take-up and unwinding wheel 4, avoiding the rope 7 from piling up in one place during winding, which would make the next unwinding operation more troublesome.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
