Description

Technical Field

[0001] This utility model belongs to the field of logging equipment technology, and in particular relates to a logging cable centering and cleaning device. Background Technology

[0002] In geological exploration, geophysical logging is often carried out, which often requires the logging probe to be safely sent to the bottom of the well and pulled out of the wellhead. The probe is repeatedly dragged up and down in the well multiple times.

[0003] Logging cables are load-bearing cables. During the logging process, the following problems exist: First, steel wire armored cables are often difficult to center at the wellhead. The steel cable is repeatedly rubbed on the drilling rig, causing severe wear and tear on the logging cable and significantly shortening its service life. Second, when the cable is pulled out of the wellhead, it often carries a large amount of mud, sand, mud, saline mud, and other corrosive viscous liquids, which continuously corrode the steel wires of the armored load-bearing cable. Auxiliary personnel can only manually wipe the steel cable repeatedly, reducing work efficiency. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] like Figures 1 to 13 As shown, a well logging cable centering and cleaning device includes: an installation cylinder 2, with a base plate 203 fixedly mounted at the bottom end of the installation cylinder 2, and a through hole 204 on the base plate 203; a telescopic swing arm, one end of which is hinged to the outer wall of the installation cylinder 2, and the other end of which is provided with a support component 6; and a positioning component, which includes two rotating wheels, with annular grooves on the outer walls of the rotating wheels, the cable 1 located inside the annular grooves of the two rotating wheels, the rotating wheels being rotatably connected to a mounting base 9, and the mounting base 9 being fixedly installed inside the installation cylinder 2.

[0051] The bottom of the annular groove of the rotating wheel is curved, matching the arc surface of cable 1. Both curved surfaces of the rotating wheels are in contact with the outer wall of cable 1. The two rotating wheels are designated as the first rotating wheel 7 and the second rotating wheel 8. The depth of the annular groove of the first rotating wheel 7 is greater than the radius of cable 1, while the depth of the annular groove of the second rotating wheel 8 is less than the radius of cable 1. The greater depth of the annular groove of the first rotating wheel 7, combined with the sidewall of the annular groove of the first rotating wheel 7, limits the movement of cable 1, effectively preventing it from swaying during movement and preventing the gap between the two rotating wheels from damaging cable 1.

[0052] The telescopic boom includes a receiving pipe 3 and a connecting rod 4. One end of the receiving pipe 3 has a hinge hole 301, through which a hinge bolt 10 passes and is hinged to a hinge plate 201 on the side wall of the mounting cylinder 2. The other end has a connecting rod 4 on its inner side, with one end installed on the inner side of the receiving pipe 3 and the other end having a support assembly 6. The telescopic boom not only allows for adjustment of the boom length to suit drilling operations of different diameters, but the hinged design also facilitates storage and transportation. The upper end of the end face of the receiving pipe 3 adjacent to the side wall of the mounting cylinder 2 is in contact with the outer side wall of the mounting cylinder 2, and the lower end of the end face of the receiving pipe 3 adjacent to the side wall of the mounting cylinder 2 has a chamfered structure, so that when the boom is in a horizontal state, the upper end of the end face of the receiving pipe 3 adjacent to the side wall of the mounting cylinder 2 limits the boom.

[0053] In some embodiments, the receiving pipe 3 has multiple horizontally arranged limiting holes 302, which are evenly distributed along the length of the receiving pipe 3. The insertion rod 4 has multiple limiting holes 401 corresponding to the limiting holes 302. A limiting bolt 11 is provided in the limiting hole 302, and the limiting bolt 11 passes through the limiting hole 302 and the limiting hole 401 in sequence and is threadedly connected to the nut. The limiting bolt 11 allows relative movement between the insertion rod 4 and the receiving pipe 3.

[0054] In some embodiments, the receiving pipe 3 has multiple vertically arranged insertion holes 303, which are evenly distributed along the length of the receiving pipe 3. The insertion rod 4 has multiple insertion holes 402 corresponding to the insertion holes 303. An insertion rod 5 is provided in each insertion hole 303, and the insertion rod 5 is inserted into the soil by passing through the insertion holes 303 and 402 in sequence. The insertion of the insertion rod 5 into the soil can prevent horizontal displacement of the device and prevent corresponding movement between the insertion rod 4 and the receiving pipe 3.

[0055] There are three support components 6, which are evenly arranged circumferentially along the axis of the mounting cylinder 2. Each support component 6 includes a screw 601 and an internally threaded tube 403 fixed at the end of the plug rod 4 away from the receiving tube 3. The screw 601 is threadedly connected to the internally threaded tube 403. A connection hole is opened on the upper side wall of the screw 601, and a handle 602 is provided in the connection hole. The axis of the handle 602 is perpendicular to the axis of the screw 601.

[0056] A ball 606 is fixed at the bottom end of the screw 601. The support assembly 6 also includes a base 603. A receiving seat 604 is fixed on the base 603. A spherical groove matching the ball 606 is opened on the receiving seat. The ball 606 is installed inside the spherical groove. The support assembly 6 can be adjusted by rotating the screw 601 to make the adjustment device level.

[0057] A strong magnetic block 605 is fixed at the bottom of the base 603, which can be easily attached to the iron plate at the wellhead.

[0058] The base plate 203 has an opening 205 that communicates with the through hole 204, and the mounting cylinder 2 has an opening 202 that corresponds to the opening 205. The width of the opening 205 and the opening 202 is greater than the diameter of the cable 1. The diameter of the through hole 204 is greater than the diameter of the cable 1. The opening 205 and the opening 202 facilitate the insertion of the cable 1.

[0059] The mounting cylinder 2 is a polygonal cylinder. In this embodiment, it is a regular hexagonal cylinder. The inner side of the mounting cylinder 2 is provided with a rubber plate 14, a positioning plate 13, and a counterweight plate 12 from bottom to top. The side lengths of the rubber plate 14, the positioning plate 13, and the counterweight plate 12 match the side lengths of the inner side of the mounting cylinder 2. The rubber plate 14, the positioning plate 13, and the counterweight plate 12 are regular hexagonal plate structures.

[0060] The rubber plate 14 has a mud-scraping hole corresponding to the cable 1. The diameter of the mud-scraping hole is smaller than the diameter of the cable 1. The mud-scraping hole is provided with a mud-scraping opening, and the width of the mud-scraping opening is smaller than the diameter of the mud-scraping hole. The mud-scraping hole can scrape off the mud on the surface of the cable 1 as the cable 1 moves upward. The mud-scraping opening makes it easy for the cable 1 to be inserted.

[0061] The positioning plate 13 has positioning holes corresponding to the cable 1. The diameter of the positioning holes is larger than the diameter of the cable 1. The positioning holes are provided with positioning openings, and the width of the positioning openings matches the diameter of the positioning holes. There are two positioning plates 13 with opposite opening directions. The positioning plates 13 are structural components made of cork. The positioning holes play a positioning role for the cable 1. The arrangement of two positioning plates 13 can prevent the cable 1 from moving along the direction of the positioning openings. The cork positioning plates 13 can prevent the cable 1 from being scratched. The positioning openings facilitate the insertion of the cable 1.

[0062] The counterweight plate 12 has mounting holes corresponding to the cable 1. The diameter of the mounting holes is larger than the diameter of the positioning holes. The mounting holes are provided with mounting openings, and the width of the mounting openings is larger than the width of the cable 1. The counterweight plate 12 is a stainless steel structural component. The counterweight plate 12 can press the rubber plate 14 to prevent the rubber plate 14 from moving together with the cable 1 during the movement.

[0063] Work process;

[0064] The implementation of this plan includes the following steps:

[0065] S1. Pass cable 1 through opening 202 and opening 205 in sequence, located inside through hole 204.

[0066] S2. Cable 1 enters the inside of the scraper hole through the scraper opening of rubber plate 14, and rubber plate 14 is placed inside the mounting cylinder 2.

[0067] S3. Cable 1 enters the inner side of the positioning hole through the positioning opening of positioning plate 13. Positioning plate 13 is placed inside the mounting cylinder 2 above the rubber plate 14.

[0068] S4. Cable 1 enters the inner side of the mounting hole through the mounting opening of counterweight plate 12. Counterweight plate 12 is placed inside the mounting cylinder 2 above the positioning plate 13.

[0069] S5. Install mounting base 9 so that the limit is located between the two rotating wheels and inside the annular groove.

[0070] S6 adjusts the length of the telescopic arm according to the wellhead diameter, and rotates screw 601 to adjust the device to a horizontal state.

[0071] The through hole 204 of the mounting cylinder 2 serves to position the cable 1, the positioning plate 13 serves to position the cable 1, and the rubber plate 14 serves to scrape the dirt off the surface of the cable 1, which improves work efficiency and prevents the cable 1 from being scratched. The telescopic swing arm not only makes the device easy to store and transport, but is also suitable for drilling operations of different diameters, thus improving the applicability of the device.
