Description

Technical Field

[0001] The present invention relates to the technical field of perforation angle detection equipment, and in particular to a detection device and method for collecting downhole perforation angles. Background Art

[0002] Perforating involves using special energy-gathering equipment to explosively open a hole at a predetermined depth in the wellbore, allowing fluids from the underground formation to enter the hole. After perforating, the perforation angle must be inspected to ensure accuracy and to determine if the perforator is damaged. If the perforation orientation is inconsistent with the direction of maximum stress, complex flow paths may form near the wellbore, resulting in additional friction and pressure drop, limiting fracture width and impacting production stimulation. Therefore, inspecting and adjusting the perforation angle ensures that fractures extend along the direction of maximum stress, minimizing energy loss. Furthermore, inspecting the perforation angle optimizes blasting directionality and avoids overbreak or underbreak.

[0003] It should be noted that during inspection, the downhole probe is inserted into the hole through the armored cable for inspection. However, during the process of lowering the downhole probe, once a landslide occurs, since the downhole probe has no first aid measures, it is very easy for the collapsed stones or soil to directly carry away the downhole probe, causing damage to the downhole probe. At the same time, the downhole probe is also easy to get stuck in the hole. At this time, since it is impossible to escape on its own, it takes a lot of manpower and time to fish out the downhole probe. Therefore, there are still many problems in the use of downhole probes.

The downward-pressing push frames move downward to squeeze the wedge-shaped push frame to move, and drive the wedge-shaped push frame to push the rotating brake frame to rotate and unfold.

[0010] Furthermore, in a preferred embodiment of the present invention, two contraction grooves are provided on the top side of the rotating sleeve, the two downward-pressing push frames are movably mounted in the two contraction grooves respectively, and a support spring is connected between the downward-pressing push frame and the rotating sleeve; A lower pressing ring is installed on the top side of the two lower pressing push frames, and the synchronous lower pressing frame moves downward to squeeze the lower pressing ring downward.

[0011] Furthermore, in a preferred embodiment of the present invention, a torsion chamber is formed on the rotating brake frame, a torsion support shaft is rotatably mounted in the torsion chamber, the torsion support shaft is mounted on the rotating sleeve, a torsion spring is mounted on the inner wall of the torsion chamber, and the torsion spring is mounted on the torsion support shaft; A driving push plate and a driven push plate are respectively installed on the protective top cover and the rotating sleeve, and the protective top cover moves downward to drive the driving push plate to move downward.

[0014] A detection method for collecting downhole perforation angles is performed based on the above-mentioned detection device for collecting downhole perforation angles, comprising the following steps: S1. The collapse of the well wall causes gravel or soil to pile up on the protective top cover. At this time, the protective top cover is forced to move downward and drives the installation ring to move. The installation ring moves downward and drives the two compression frames to move downward. The downward movement of the compression frames drives the synchronous downward movement of the lower pressure frame, so that the locking hook is squeezed and recovered by the downhole probe. The locking hook slides horizontally in the transverse sliding groove and forces the locking spring. When the locking hook moves to the position of the locking groove, the rebound force of the locking spring causes the locking hook to be stuck in the locking groove, thereby fixing the position of the installation ring; S2, when the compression frame moves downward, the start switch is triggered, so that the driving motor drives the gear column to rotate, the gear column drives the driving ring gear to rotate, the driving ring gear drives the protective top cover to rotate, and the protective top cover drives the two rotary escape frames to rotate and clean the collapsed mud or stones, and actively free the underground exploration pipe; the rotation of the protective top cover drives the two contact lifting rods to rotate synchronously, and the contact lifting rods are squeezed upward by the arc top plate and drive the recovery spring to bear force. When the contact lifting rods move upward, they drive the rotary escape frame to move upward, and the protective top cover continues to rotate, so that the contact lifting rods are separated from the arc top plate, and under the rebound force of the recovery spring, the contact lifting rods drive the rotary escape frame to move downward, thereby driving the rotary escape frame to move up and down to escape; S3. The synchronous downward movement of the lower pressure frame squeezes the lower pressure ring downward, so that the lower pressure ring pushes the two lower pressure push frames downward. When the lower pressure push frame moves downward, it squeezes the wedge-shaped push frame to move. When the wedge-shaped push frame moves, it pushes the rotating brake frame to rotate, so that the rotating brake frame rotates and expands and gets stuck on the well wall, thereby stopping the downhole probe pipe from moving downward urgently. The rotation of the protective top cover drives the driven push plate to rotate by driving the push plate, so that the rotating sleeve drives the two rotating brake frames to rotate, and the collapsed gravel or soil is further cleaned; S4. The two rotating brake frames rotate and unfold and support the well wall, so that when the downhole probe stops moving downward, the cable stops moving downward, and the downhole probe loses its downward force, and the cable no longer compresses the supporting wheel; under the rebound force of the pop-up spring, the mounting frame drives the pop-up frame to pop out, and the pop-up frame drives the two V-shaped frames to move when popping out, and the two V-shaped frames squeeze the two squeezing columns to move, and the movement of the two squeezing columns drives the two brake gear frames to move, so that the two brake gear frames clamp the cable and brake the cable.

[0015] The beneficial effects of the detection device and method for collecting downhole perforation angles proposed by the present invention are: In the present invention, through the setting of the rotary escape device, when the downhole probe tube moves downward, if the well wall collapses, causing gravel or soil to pile up on the protective top cover, the protective top cover will protect the downhole probe tube and drive the protective top cover to rotate. The protective top cover drives the two rotary escape frames to rotate and clean the collapsed soil or stones, thereby enabling the downhole probe tube to be actively escaped; in addition, when the protective top cover rotates, it drives the two contact lifting rods to rotate synchronously, so that the contact lifting rods drive the rotary escape frame to move up and down, further ensuring the escape effect, thereby effectively ensuring the safety of the downhole probe tube and avoiding data loss.

[0016] Furthermore, in the present invention, through the provision of a braking and escape device, in the event of a landslide, the two rotating brake frames rotate and unfold and get stuck on the well wall, causing the downhole probe to stop moving downward urgently, facilitating subsequent escape operations; when the protective top cover rotates, the protective top cover drives the driven push plate to rotate by driving the push plate, and then the rotating sleeve drives the two rotating brake frames to rotate, further cleaning the collapsed gravel or soil, and further helping the downhole probe to escape.

[0017] Furthermore, in the present invention, through the setting of the active braking device, when the two rotating brake frames are rotated and unfolded and supported on the well wall, the downhole probe stops moving downward, and the cable also stops moving downward. At this time, the downhole probe loses the falling force, so that the cable no longer compresses the support wheel, and at this time, under the rebound force of the pop-up spring, the mounting frame drives the pop-up frame to pop out, and the pop-up frame drives the two V-shaped frames to move when popping out, so that the two V-shaped frames squeeze the two squeezing columns to move, and the movement of the two squeezing columns drives the two brake gear frames to move, so that the two brake gear frames clamp the cable, thereby effectively reminding the staff of underground collapse, and at the same time effectively avoiding the problem of loss of the downhole probe due to accidental falling of the downhole probe.

At the same time, the rotation of the protective top cover 3 drives the two rotating escape frames 401 to rotate, rotating and cleaning the collapsed soil or stones, thereby enabling the downhole probe 1 to be actively escaped.

[0028] More specifically, the embodiment of the present invention further includes a braking and releasing device 5, which is mounted on the downhole probe 1 and is used to actively brake the downhole probe 1. The braking and releasing device 5 includes a rotating sleeve 501, which is rotatably mounted on the downhole probe 1.

It should be noted that in the embodiment of the present invention, in the event of a landslide, the rotating brake frames 502 rotate and deploy and become stuck on the well wall, causing the downhole probe 1 to urgently stop moving downward, facilitating subsequent escape operations. In addition, when the protective top cover 3 rotates, the protective top cover 3 drives the driven push plate 513 to rotate by driving the push plate 512, thereby causing the rotating sleeve 501 to drive the two rotating brake frames 502 to rotate, further clearing the collapsed gravel or mud, and further helping the downhole probe 1 to escape.

The starting switch 417 is electrically connected to the drive motor 415. The two compression frames 402 extend into the two downward pressure limiting grooves 408, respectively, and are each equipped with an upward push spring 409. The upward push spring 409 is installed on the inner wall of the downward pressure limiting groove 408. It should be noted that in the embodiment of the present invention, when the compression frame 402 moves downward, the starting switch 417 is triggered, causing the drive motor 415 to rotate the gear column 416, which in turn causes the gear column 416 to rotate the drive ring gear 414. The drive ring gear 414 drives the protective top cover 3 to rotate.

It should be noted that in the embodiment of the present invention, the downward-pressing push frames 503 squeeze the wedge-shaped push frames 505 when moving downward, causing the wedge-shaped push frames 505 to slide horizontally in the pull-out slots 508.

[0036] Further, please refer to the description of the accompanying drawings Figure 9-10 The detection device for collecting the downhole perforation angle provided by the embodiment of the present application, the active brake device 6 further comprises two mounting sleeves 605, the two mounting sleeves 605 are installed on the two sides of the brake base 601 respectively; in addition, a pull rod 606 is slidably installed in each of the two mounting sleeves 605, an extrusion column 608 is installed on one side of each of the two pull rods 606, and a brake tooth rack 607 is installed on each of the two extrusion columns 608. It should be noted that in the embodiment of the present application, when the support wheel 604 loses the compression force, the mounting frame 603 drives the ejection frame 602 to eject under the resilience of the ejection spring 610, the ejection frame 602 drives the two V-shaped frames 609 to move when it is ejected, and then the two brake tooth racks 607 clamp the cable 2.

[0037] More specifically, in this embodiment of the present invention, V-shaped frames 609 are mounted on both sides of the ejection frame 602. These two V-shaped frames 609 are used to compress the two squeezing posts 608. Furthermore, an ejection spring 610 is mounted on the bottom side of the ejection frame 602, and the ejection spring 610 is mounted on the bottom inner wall of the brake base 601. It should be noted that in this embodiment of the present invention, the two V-shaped frames 609 compress the two squeezing posts 608 to move, and the movement of the two squeezing posts 608 drives the movement of the two brake racks 607, thereby achieving the purpose of synchronously moving the two brake racks 607 to clamp the cable 2.

[0038] In summary, the working principle of the detection device for collecting downhole perforation angles provided by the embodiment of the present invention, that is, the detection method corresponding to the detection device for collecting downhole perforation angles provided by the embodiment of the present invention, is as follows: When the downhole probe 1 moves downward, if the well wall collapses, gravel or soil will pile up on the protective top cover 3. At this time, the protective top cover 3 is forced to move downward and drives the installation ring 403 to move. The installation ring 403 moves and drives the two compression frames 402 to move downward, so that the two compression frames 402 move vertically in the two downward pressure limiting grooves 408, and the two upward push springs 409 are stressed. When the compression frame 402 moves, it drives the synchronous downward pressure frame 407 to move downward, so that the locking hook 411 is squeezed and recovered by the downhole probe 1, and the locking hook 411 slides horizontally in the transverse slide groove 410, and the locking spring 412 is stressed. Force, when the locking hook 411 moves to the position of the locking groove 413, under the rebound force of the locking spring 412, the locking hook 411 is stuck in the locking groove 413, thereby fixing the position of the mounting ring 403, and at the same time, the compression frame 402 triggers the starting switch 417 when moving downward, so that the driving motor 415 drives the gear column 416 to rotate, the gear column 416 drives the driving ring gear 414 to rotate, and the driving ring gear 414 drives the protective top cover 3 to rotate, and the protective top cover 3 drives the two rotating escape frames 401 to rotate, and the collapsed soil or stones are rotated and cleaned, so that the downhole probe 1 can be actively escaped. It should be noted that when the protective top cover 3 rotates, the two contact lifting rods 404 are driven to rotate synchronously, so that the contact lifting rods 404 are squeezed and moved upward by the arc-shaped top plate 406 and the recovery spring 405 is subjected to force. When the contact lifting rods 404 move upward, the rotary escape frame 401 moves upward, and when the protective top cover 3 continues to rotate, the contact lifting rods 404 are separated from the arc-shaped top plate 406. At this time, under the rebound force of the recovery spring 405, the contact lifting rods 404 drive the rotary escape frame 401 to move downward quickly, thereby realizing the up and down movement of the rotary escape frame 401, further ensuring the escape effect; Furthermore, when the synchronous lower pressing frame 407 moves downward, the lower pressing ring 504 is squeezed to move downward, so that the lower pressing ring 504 pushes the two lower pressing push frames 503 to move downward, and the lower pressing push frames 503 move vertically in the contraction groove 506. At the same time, when the lower pressing push frame 503 moves downward, it squeezes the wedge-shaped push frame 505 to move, so that the wedge-shaped push frame 505 slides horizontally in the pull-out groove 508. When the wedge-shaped push frame 505 moves, it pushes the rotating brake frame 502 to rotate, so that the rotating brake frame 502 is rotated in the torsion cavity 509. The support shaft 510 rotates internally, and the torsion spring 511 is stressed, thereby causing the rotating brake frame 502 to rotate and expand and get stuck on the well wall, so that the downhole probe 1 stops moving downward urgently, facilitating the subsequent escape operation; in addition, when the protective top cover 3 rotates, the protective top cover 3 drives the driven push plate 513 to rotate by driving the push plate 512, so that the rotating sleeve 501 drives the two rotating brake frames 502 to rotate, thereby further clearing the collapsed gravel or mud, and further helping the downhole probe 1 to escape; Furthermore, when the two rotating brake frames 502 rotate and unfold and support the well wall, so that the downhole probe 1 stops moving downward, the cable 2 also stops moving downward, and the downhole probe 1 loses the downward force, so that the cable 2 no longer compresses the support wheel 604. At this time, under the rebound force of the pop-up spring 610, the mounting frame 603 drives the pop-up frame 602 to pop out, and the pop-up frame 602 drives the two V-shaped frames 609 to move when popping out. The two V-shaped frames 609 squeeze the two squeezing columns 608 to move, and the two squeezing columns 608 move to drive the two brake gear frames 607 to move, so that the two brake gear frames 607 clamp the cable 2, thereby effectively reminding the staff of the problem of underground collapse and effectively avoiding the accidental falling of the downhole probe 1. The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.

The collapse of the well wall causes gravel or soil to pile up on the protective top cover. At this time, the protective top cover is forced to move downward and drives the installation ring to move. The installation ring moves downward and drives the two compression frames to move downward. The downward movement of the compression frames drives the synchronous downward movement of the lower pressure frame, so that the locking hook is squeezed and recovered by the downhole probe. The locking hook slides horizontally in the transverse sliding groove and forces the locking spring.
