Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of perforating gun, and particularly relates to a perforating gun device with adjustable orientation angle. BACKGROUND

[0002] The perforating gun is a combination of equipment for perforating oil and gas wells and its supporting parts. The widely used perforating gun is a shaped charge perforating gun. The shaped charge perforating gun generates a shaped jet through the energy accumulation phenomenon of a shaped charge cup explosion, and perforates the stratum. It should be noted that the Chinese patent application No. CN201510696961.5 discloses a water jet perforating gun with adjustable angle, which adjusts the circumferential 45° angle of the nozzle through one-time reciprocating movement of the gun moving part. The nozzles on the same generatrix are aligned with another group of perforating flow channels in the circumferential direction, so as to change the nozzle jet angle.

[0003] From the above patent, it can be known that the existing perforating gun can flexibly adjust the angle during work. However, in the specific operation process, the perforating gun cannot be observed when it enters the casing. Therefore, when the observation camera is inserted into the casing, the casing may be deformed due to condensation impurities or impact, extrusion and other reasons during construction, so that the perforating gun is blocked, and thus the perforating work can only be stopped first, and the casing is cleaned or the working angle is adjusted, and then the perforating work can be continued, thereby causing the interruption of the perforating work. In addition, cleaning the casing or adjusting the working angle requires a lot of time and labor, so that the perforating work cannot be efficiently carried out, and the perforating gun may be stuck due to the blockage or deformation of the casing, resulting in damage to the perforating gun.

[0071] Further, when the observation camera 2 drives the sleeve ring 4 to move in the sleeve, if the sleeve is deformed or encounters condensed impurities, any one or more adjustment rotating rods 504 will be hindered to retract, the adjustment rotating rods 504 move in the telescopic support frame 502 through the cleaning adjustment frame 503, and drive the push plate 507 to move, and in turn drive the return spring 506 to be stressed, the push plate 507 drives the trigger frame 515 to move, the trigger frame 515 pulls the two return springs 516 to be stressed, and at the same time, the movement of the trigger frame 515 drives the trigger plate 519 to press the switch 518, so that the adjustment motor 510 is started, the adjustment motor 510 drives one of the synchronous gears 513 to rotate through the drive gear 511, the other synchronous gear 513 is driven to rotate through the synchronous rotating shaft 512, the synchronous gear 513 drives the synchronous gear ring 514 to rotate, and the synchronous gear ring 514 drives the rotating ring 501 to rotate, so that the rotating ring 501 drives the plurality of cleaning adjustment frames 503 to rotate through the plurality of telescopic support frames 502, thereby cleaning the sleeve or adjusting the working angle, and after adjustment, the plurality of cleaning adjustment frames 503 are reset under the retraction force of the plurality of return springs 506, thereby realizing the automatic closing of the adjustment motor 510;

[0072] Further, when the adjustment rotating rod 504 drives the cleaning adjustment frame 503 to move, the synchronous belt drives the driving ring 603 to move, the driving ring 603 drives the two opening and closing drive frames 607 to move, the opening and closing drive frames 607 slide in the sliding groove 609 and drive the return spring 610 to be stressed, the opening and closing drive frames 607 move to drive the opening and closing frame 606 to rotate through the drive shaft 608, and at the same time, the drive shaft 608 slides in the opening and closing frame 606, the opening and closing frame 606 rotates to drive the rotating seat 604 to rotate through the connecting rotating shaft 605, so that the rotating seat 604 drives the closing rotating plate 601 to rotate, thereby closing the observation camera 2, avoiding that impurities fall on the observation camera 2 when cleaning or adjusting the sleeve, and affecting the observation of the observation camera 2; in addition, when the cleaning adjustment frame 503 is reset and no longer presses the opening and closing drive frame 607 through the driving ring 603, the opening and closing drive frame 607 is reset under the reaction force of the return spring 610, thereby realizing the automatic unfolding of the closing rotating plate 601;

[0073] Further, in the process of closing the closing turn plate 601, when the closing turn plate 601 approaches the observation camera 2, at this time, the cleaning scraper 702 is in contact with the observation camera 2, at the same time, the compression frame 709 is extruded and compressed by the frame of the observation camera 2, and the supporting spring 710 is forced to move, the compression frame 709 moves to drive the adapter rod 711 to move in the extrusion groove 712, and then drive the rotating connecting rod 705 to rotate, the rotating connecting rod 705 rotates on the center shaft 707 and drives the push-pull frame 704 to move through the linkage shaft 706, at the same time, the linkage shaft 706 slides in the push-pull frame 704, the push-pull frame 704 moves to drive the sliding seat 701 to move, the sliding seat 701 drives the cleaning scraper 702 to clean the surface of the observation camera 2, and with the continuous closing of the closing turn plate 601, the cleaning scraper 702 is extruded and retracted into the sliding seat 701, at the same time, the buffer spring 703 is forced to move, so that when the closing turn plate 601 is closed, the cleaning of the observation camera 2 by the cleaning scraper 702 is not affected, and the automatic cleaning of the observation camera 2 is realized.

[0074] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
