Description

Technical Field

[0001] This utility model relates to the field of oil and gas well measurement technology, and more specifically, to a dual-depth channel measurement device for oil and gas wells. Background Technology

[0002] In the exploration and development of oil and gas wells, accurate measurement of various parameters plays a crucial role in ensuring efficient and safe production operations and maximizing resource recovery. Depth measurement, as a fundamental and critical parameter measurement, directly relates to the accurate understanding of the internal structure of oil and gas wells, reservoir location, and thickness.

[0003] Currently, in oilfield testing instruments, winch depth measurement mainly relies on a Martin-Dike depth wheel driving a photoelectric encoder to transmit depth signals. During winter construction in northern regions, fluid carried by the cable from the well may freeze on the cable or the depth wheel as it travels to the winch. This can cause relative movement between the cable and the Martin-Dike depth wheel, and the icing may also alter the outer diameter of the depth wheel, resulting in deviations in the depth readings output by the Martin-Dike.

Detailed Implementation

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1 To be continued Figure 5 As shown, an embodiment of this utility model provides a dual-depth channel measuring device for oil and gas wells, including a detection body 1, a fixing device 2, and an antifreeze device 3. Both sides of the detection body 1 are fixedly installed with the fixing device 2, and the antifreeze device 3 is fixedly installed on the top of the detection body 1.

[0024] like Figure 3 As shown, the fixing device 2 includes an upper fixing block 21 and a lower fixing block 22, a snap-fit ​​rod 24 and a connecting rod 26. A movable frame 29 is movably sleeved inside the upper fixing block 21. A fixing bolt 211 is rotatably installed on the side of the movable frame 29. The fixing bolt 211 is threaded onto one end of the upper fixing block 21. Snap-fit ​​bolts 210 are fixedly installed at both ends of the movable frame 29. The snap-fit ​​bolts 210 are movably sleeved inside the upper fixing block 21. A movable groove 23 is opened inside the right side of the upper fixing block 21.

[0025] The snap-fit ​​rod 24 is fixedly installed on the left side of the top of the lower fixing block 22, the connecting rod 26 is fixedly installed on the right side of the top of the lower fixing block 22, and the top of the connecting rod 26 is fixedly installed with a limit block 28.

[0026] like Figure 2 As shown, the testing machine body 1 includes an upper fixed frame 11 and a lower fixed frame 12. Both ends of the upper fixed frame 11 are fixedly installed with a set of straightening wheels 15. A tension straightening wheel 13 is rotatably installed on the right side inside the upper fixed frame 11. A lifting lug 110 is fixedly installed on the top of the upper fixed frame 11. A tension wheel 16 is provided inside the lower fixed frame 12. Multiple slotted straightening wheels 14 are rotatably installed inside the lower fixed frame 12. Both ends of the left side of the upper fixed frame 11 are fixedly installed with a side frame 18. An encoder 17 is fixedly installed on the top of the side frame 18. A metering wheel 19 is fixedly connected to the output end of the encoder 17.

[0027] like Figure 3 As shown, the upper fixing block 21 is fixedly installed at both ends of the upper fixing frame 11, the lower fixing block 22 is fixedly installed at both ends of the lower fixing frame 12, the limiting block 28 is movably sleeved inside the movable groove 23, the upper ends of the connecting rod 26 and the snap-fit ​​rod 24 are both provided with snap-fit ​​grooves 25, the outer surfaces of the snap-fit ​​rod 24 and the connecting rod 26 are rotatably mounted with positioning wheels 27, the snap-fit ​​rod 24 is movably sleeved at the lower end of the upper fixing block 21, and the snap-fit ​​bolt 210 is snap-fitted inside the snap-fit ​​groove 25.

[0028] Both the connecting rod 26 and the snap-fit ​​rod 24 have snap-fit ​​grooves 25 at their upper ends. With the action of the snap-fit ​​bolts 210, when the snap-fit ​​rod 24 and the connecting rod 26 are sleeved on the bottom of the upper fixing block 21, the moving frame 29 drives the snap-fit ​​bolts 210 at both ends to move to the right by rotating the fixing bolts 211. This causes the snap-fit ​​bolts 210 to snap into the inside of the snap-fit ​​grooves 25, allowing the positioning wheels 27 on the outer surface of the snap-fit ​​rod 24 and the connecting rod 26 to install the cable. The installation is simple and convenient, improving the efficiency of cable installation.

[0029] The positioning wheel 27 supports the cable and prevents it from moving on the side of the detection body 1, which would cause wear on the cable or the detection body 1 due to friction.

[0030] like Figure 4 As shown, the antifreeze device 3 includes a heating frame 31, a movable tube 33, and a heating tube 38. The heating frame 31 is fixedly installed on the top of the upper fixed frame 11. A controller 32 is fixedly installed on the top of the heating frame 31. A telescopic hole 37 is opened inside the heating frame 31. The movable tube 33 is movably sleeved inside the telescopic hole 37. A rotating head 34 is rotatably installed on the bottom of the heating frame 31. An arc plate 35 is fixedly connected to the bottom of the rotating head 34. A buffer spring 36 is movably sleeved on the outer surface of the movable tube 33 and the rotating head 34. The buffer spring 36 is located between the heating frame 31 and the arc plate 35.

[0031] By utilizing the buffer spring 36, the arc plate 35 rotates between the movable tube 33 and the rotating head 34 according to the direction of the cable, so that the arc plate 35 can be automatically adjusted according to the position of the cable.

[0032] The heating tube 38 is fixedly connected to the middle of the arc plate 35, and the controller 32 is fixedly connected to the heating tube 38 through wires. Both ends of the inner wall of the arc plate 35 are rotatably installed with ball bearings 39.

[0033] The ball bearings 39 allow the arc plate 35 to be fitted onto the outer surface of the cable, and the ball bearings 39 facilitate the movement of the cable inside the arc plate 35. At the same time, the heating tube 38 heats the cable to prevent the cable surface from freezing, improves the movement between the cable and the Martin-Dick, and improves the detection accuracy of the device.

[0034] The working process of this utility model is as follows:

[0035] In use, by rotating the fixing bolt 211, the moving frame 29 moves the locking bolts 210 at both ends of the moving frame 29 to the left, so that the locking bolts 210 move out of the locking groove 25. Pull the lower fixing frame 12 down to separate the locking rod 24 from the upper fixing block 21. At this time, the connecting rod 26 and the limiting block 28 move down to separate the upper fixing frame 11 and the lower fixing frame 12. Then, the cable is passed between the upper fixing frame 11 and the lower fixing frame 12, so that the cable is placed between the tension straightening wheel 13 and the slotted straightening wheel 14, and between the straightening wheel groups 15 at both ends. Then, push the lower fixing frame 12 to make the locking rod 24 and the connecting rod 26 engage inside the upper fixing block 21. By rotating the fixing bolt 211 in the opposite direction, the moving frame 29 moves the locking bolts 210 to the right, so that the locking bolts 210 engage inside the locking groove 25, thereby fixing the upper fixing frame 11 and the lower fixing frame 12, and the cable installation is completed.

[0036] During the measurement process, the heating tube 38 is controlled by the controller 32 to heat the cable. When the cable moves inside the upper fixed frame 11 and the lower fixed frame 12, the heating tube 38 heats the surface of the cable, preventing the surface of the cable from freezing, improving the movement between the cable and the Martin-Dick, and improving the detection accuracy of the device.
