Description

Technical Field

[0001] This invention relates to a perforator, and more particularly to a carrier-powered perforator with a support function. Background Technology

[0002] Perforators are crucial tools in oil and gas resource development, used to create fluid channels between the wellbore and the reservoir. Their basic principle involves detonating a perforating gun at a predetermined depth downhole, generating a high-speed metal jet that penetrates the casing, cement sheath, and enters the formation, thus forming a perforation channel. Common perforators typically consist of a perforating gun, outer casing, perforating gun, and detonation control system. As oil and gas development extends to more complex geological conditions, traditional perforators are no longer sufficient to meet the demands for efficient and stable operation in deep wells, under high pressure, and high temperature environments. Therefore, improvements in structural design and functional expansion are urgently needed.

[0003] After perforation is completed, if the resulting perforated channels lack effective support, they are prone to problems such as diameter reduction, local collapse, or obstruction of flow channels due to factors such as formation pressure, rock creep, or debris backfilling. This can affect the flow efficiency of formation fluids and reduce oil well productivity. The problem of poor channel stability is particularly prominent under complex geological conditions such as low-permeability formations and loose sandstone formations. In existing technologies, most perforation devices only complete the perforation operation and lack the function of supporting or maintaining the channels after perforation. The lack of means to maintain the stability of the perforated channels after perforation limits subsequent production efficiency, increases the frequency of well workover and repair operations, and raises development costs. Summary of the Invention

[0004] In order to overcome the shortcomings of existing perforators that lack the function of effectively supporting and maintaining the perforation channel after completing the perforation operation, which leads to problems such as channel narrowing, local collapse or obstruction of the flow channel, the present invention provides a carrier-based power-enhancing perforator with a support function.

[0005] The technical solution is as follows: A carrier-powered perforator with a support function includes a perforating gun, an outer tube, perforating projectiles, and a detonation wire. The outer tube is provided on the outside of the perforating gun, and multiple perforating projectiles are provided on the perforating gun. A carrier-powered device is integrated into the head of each perforating projectile. The multiple perforating projectiles are connected by the detonation wire. The system also includes a support mechanism disposed between two adjacent perforating projectiles. The support mechanism includes an isolation cylinder, a guide rod, a connecting plate, a shape memory alloy bracket, a guide plate, a storage spring, a launching mechanism, and a storage mechanism. The isolation cylinder is connected to the perforating gun. A guide plate is connected to one side of the isolation cylinder. A guide rod is slidably connected to the guide plate. A connecting plate is slidably connected to the outside of the guide rod. A shape memory alloy bracket is connected to the end of the connecting plate facing the perforating projectile launch port. The shape memory alloy bracket is connected to the guide rod. A storage spring is connected between the guide plate and the connecting plate. A launching mechanism is installed on the guide plate. A storage mechanism is installed at the end of the isolation cylinder away from the perforating projectile launch port.

[0006] Furthermore, the power storage mechanism includes a fixed plate, a winding shaft, a nylon rope, a worm gear, and a worm. The fixed plate is connected to the inner wall of the isolation cylinder. The winding shaft is rotatably mounted on the fixed plate, and the nylon rope is wound on the winding shaft. A through hole is opened on the guide plate for the nylon rope to pass through. The two ends of the nylon rope are respectively connected to the winding shaft and the connecting plate. The worm gear is connected to the winding shaft, and the worm gear meshing with the worm gear is rotatably connected to the fixed plate.

[0007] Furthermore, the launching mechanism includes a rotating ring, an annular cutter, a force plate, and a connecting rod. The rotating ring is rotatably connected to the guide plate, and the annular cutter, which is sleeved on the outside of the nylon rope, is connected to the rotating ring. The force plate is slidably connected to the isolation cylinder, and the connecting rod is movably connected to the force plate at the eccentric part of the rotating ring.

[0008] Furthermore, multiple rollers are provided on the outer side of the connecting plate, and the rollers contact the inner wall of the isolation cylinder.

[0009] Furthermore, it also includes a fusion mechanism, which includes a metal heat-conducting ring and a heat-conducting frame. The outer side of the isolation cylinder is provided with a metal heat-conducting ring, and the inner side of the isolation cylinder is provided with a heat-conducting frame. The heat-conducting frame is in contact with the nylon rope and passes through the isolation cylinder and is connected to the metal heat-conducting ring.

[0010] Furthermore, the bore wall in the middle of the guide disc is provided with rifling helical grooves, and the outer side of the guide rod is provided with a drive belt adapted to the rifling helical grooves.

[0011] Furthermore, it also includes a protective film, with the end of the isolation cylinder facing the firing port of the projectile connected to the protective film.

[0012] Furthermore, a ball bearing is installed at the end of the guide rod facing the firing port of the projectile.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention utilizes the high-temperature recovery deformation characteristics of the shape memory alloy bracket by setting a support mechanism inside the perforation gun. This allows the bracket to quickly expand and fit against the inner wall of the perforation channel after perforation, effectively preventing problems such as narrowing of the channel, local collapse, or obstruction of the flow channel caused by factors such as formation pressure, rock creep, or debris backfilling. This significantly improves the long-term stability and flow capacity of the channel.

[0014] 2. When the shape memory alloy support of this invention enters the perforation channel, its edges can dynamically scrape away debris, deposits, or other impurities adhering to the inner wall of the channel, ensuring the cleanliness of the channel entrance and inner wall, thereby improving the flow performance of formation fluids. Furthermore, rollers are provided on the connecting disc to reduce frictional resistance with the inner wall of the channel, facilitating smooth entry of the support into the channel and further enhancing the adaptability and reliability of the device under complex well conditions. Simultaneously, the universal ball bearing design installed at the end of the guide rod allows it to roll forward even when encountering local obstructions, preventing jamming and improving overall flexibility and stability.

[0015] 3. This invention employs a main triggering method of cutting the nylon rope with a ring cutter, and is equipped with a fusing mechanism as a backup triggering method. Once the main triggering method fails, the fusing mechanism can automatically fuse the nylon rope in the high-temperature environment after the perforation projectile detonates, releasing the energy of the storage spring and pushing the connecting disc, shape memory alloy bracket, and guide rod outward.

[0016] 4. The cooperation between the rifling spiral grooves and the drive belt enables the support assembly to rotate synchronously during the ejection process, which not only improves the cleaning effect but also enhances the stability of the entry channel. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] Example 1: A carrier-based power-enhancing perforator with a support function, such as Figures 1-11As shown, the device includes a perforating gun 1, an outer tube 2, perforating projectiles 3, a detonating wire 4, and a support mechanism 5. The outer tube 2 is provided on the outside of the perforating gun 1. Perforating projectiles 3 are arranged spirally at intervals along the axial direction of the perforating gun 1. Each perforating projectile 3 has a carrier energy booster device 31 integrated into its head. The carrier energy booster device 31 is filled with a composite agent. Multiple perforating projectiles 3 are connected by the detonating wire 4. The outer tube 2 encloses the perforating gun 1, perforating projectiles 3, and detonating wire 4. A support is provided between every two adjacent perforating projectiles 3. Mechanism 5 consists of multiple support mechanisms 5 arranged in a spiral pattern. Each support mechanism 5 includes an isolation cylinder 51, a guide rod 52, a connecting plate 53, a shape memory alloy bracket 54, a guide plate 55, a storage spring 56, a launching mechanism 57, and a storage mechanism 58. The isolation cylinder 51 is connected inside the perforating gun 1, with both ends penetrating the sidewall of the perforating gun 1. The isolation cylinder 51 is made of high-temperature resistant alloy material and has an outer heat insulation layer, effectively blocking the high temperatures generated during perforation and preventing internal components from deforming or failing due to thermal shock. Simultaneously, the cylinder structure is reinforced, possessing good impact resistance and avoiding mechanical damage caused by the complex downhole environment. Each isolation cylinder 51 has a guide plate 55 connected to one side. The guide plate 55 has a guide hole in its center, and a guide rod 52 is slidably connected within the guide hole. A connecting plate 53 is slidably connected to the outer side of the guide rod 52. The connecting plate 53 can slide along the axial direction of the guide rod 52. A [missing information - likely a device or mechanism] is connected to the end of the connecting plate 53 facing the launching port of the perforating projectile 3. The shape memory alloy bracket 54 is spiral in shape, with a conical firing end and a cylindrical end. The shape memory alloy bracket 54 is sleeved on the outside of the guide rod 52. The firing end of the shape memory alloy bracket 54 is connected to the guide rod 52. The energy storage spring 56 is connected between the guide plate 55 and the connecting plate 53. The energy storage spring 56 is sleeved on the outside of the guide rod 52. The firing mechanism 57 is installed on the guide plate 55. The energy storage mechanism 58 is installed at the end of the isolation cylinder 51 away from the firing port of the perforated bullet 3.

[0031] The power storage mechanism 58 includes a fixed plate 581, a winding shaft 583, nylon ropes 584, a worm gear 585, and a worm 586. The fixed plate 581 is connected to the inner wall of the right side of the isolation cylinder 51. A groove 582 is provided on the side of the fixed plate 581 facing the guide plate 55. The winding shaft 583 is installed in the groove 582. The winding shaft 583 is rotatably connected to the fixed plate 581. Two nylon ropes 584 are wound on the winding shaft 583. Two through holes are provided on the guide plate 55 for the nylon ropes 584 to pass through. One end of the nylon rope 584 is connected to the winding shaft 583, and the other end is connected to the connecting plate 53. The worm gear 585 is connected to the middle of the winding shaft 583. A worm 586 that meshes with the worm gear 585 is rotatably connected to the fixed plate 581. A cross groove is machined on the end of the worm 586 facing the outside of the fixed plate 581 to facilitate rotation operation using an electric screwdriver.

[0032] The launching mechanism 57 includes a rotating ring 571, an annular cutter 572, a force-bearing plate 573, and a connecting rod 574. The rotating ring 571 is rotatably connected to the right side of the guide disc 55. The guide rod 52 passes through the center of the rotating ring 571. Two annular cutters 572, which are respectively sleeved on the outside of the nylon rope 584, are embedded on the rotating ring 571. The force-bearing plate 573 is T-shaped. The vertical part of the force-bearing plate 573 is slidably connected to the isolation cylinder 51. The upper end of the vertical part of the force-bearing plate 573 extends into the isolation cylinder 51 and is movably connected to the connecting rod 574. The connecting rod 574 is movably connected to the eccentric part of the rotating ring 571. The horizontal part of the force-bearing plate 573 is located outside the isolation cylinder 51. It receives the shock wave energy generated during the firing process and transmits the energy to the connecting rod 574, thereby triggering the rotation of the annular cutter 572 to cut the nylon rope 584 and ensure that the support mechanism 5 can respond and deploy in a timely manner.

[0033] Furthermore, eight rollers 531 are evenly spaced on the outer circumference of the connecting plate 53. The rollers 531 contact the inner wall of the isolation cylinder 51 to reduce frictional resistance during movement.

[0034] It also includes a protective film 9. The end of the isolation cylinder 51 facing the firing port of the perforated bullet 3 is connected to the protective film 9 to prevent external impurities from entering the interior of the support mechanism 5.

[0035] When assembling the support mechanism 5, first insert an electric screwdriver into the cross slot at the top of the worm 586 and start the screwdriver to rotate the worm 586. The worm 586 meshes with the worm wheel 585, causing the worm wheel 585 to rotate synchronously. The rotation of the worm wheel 585 drives the winding shaft 583 to rotate synchronously through the coupling. During the rotation of the winding shaft 583, the nylon rope 584 is orderly wound around its surface, and through traction, it drives the connecting disc 53 to move to the right, thereby compressing the energy storage spring 56, causing the guide rod 52 and the shape memory alloy bracket 54 to retract completely into the isolation cylinder 51. After the energy storage spring 56 has been fully compressed, turn off the electric screwdriver. Then, cover the left end of the isolation cylinder 51 with a protective film 9 and firmly fix it by adhesive or welding. Finally, weld the assembled isolation cylinder 51 to the corresponding position inside the perforating gun 1 to complete the installation of the support mechanism 5.

[0036] After connecting the perforator to the cable, it is transported downhole to the target formation. The outer casing 2 protects the internal components from damage caused by wellbore friction or other external forces during the downhole process. Once the perforator reaches the predetermined depth, the surface control equipment sends an ignition signal, which detonates each perforating shell 3 sequentially via the detonation wire 4. After the perforating projectile 3 is detonated, it generates a high-speed metal jet that penetrates the outer casing 2 and penetrates deep into the formation, forming a perforation channel. During the detonation of the perforating projectile 3, the carrier wave booster device 31, under the action of the detonation wave, penetrates the outer casing 2 and the formation along the perforation direction. Simultaneously, the composite agent in the carrier wave booster device 31 undergoes secondary combustion, releasing high-temperature and high-pressure gas, expanding the perforation channel and extending the fracture extension distance. The shock wave generated during the perforation process acts on the inside of the perforating gun 1, impacting the force plate 573 and causing it to move into the isolation cylinder 51. This movement, via the connecting rod 574, drives the annular cutter 572 to rotate. After the annular cutter 572 rotates and cuts the nylon rope 584, the energy storage spring 56 releases energy, pushing the connecting disc 53, the shape memory alloy support 54, and the guide rod 52 outwards. During the ejection process, the end of the guide rod 52 first pierces the protective membrane 9, then continues to extend outwards until it abuts against the well wall. At this point, the energy storage spring 56 is not yet fully extended. During this process, the impact energy generated by the detonation of the perforating projectile 3 acts synchronously on the outer casing 2, causing it to be destroyed or ruptured at the same time as the projectile 3 is launched, providing space and a channel for the deployment of the support mechanism 5. Subsequently, the perforator continues to be transported downwards via cable, aligning the support mechanism 5 with the formed perforation channel. Under the further action of the storage spring 56, the connecting disc 53, the shape memory alloy support 54, and the guide rod 52 are precisely ejected into the perforation channel. When the shape memory alloy support 54 enters the channel, its cylindrical portion can effectively scrape away debris or deposits from the inner wall of the channel, enhancing the cleanliness of the perforation channel and helping to improve the flow performance of formation fluids. The connecting disc 53 is equipped with rollers 531, which can reduce the frictional resistance between it and the inner wall of the channel, facilitating smooth entry. As the temperature inside the perforation channel rises after perforation, the shape memory alloy support 54 recovers its shape under high temperature, gradually unfolds and elongates along the extension direction of the perforation channel, pushing the connecting plate 53 to move towards the well wall, thereby achieving active support for the perforation channel, preventing it from narrowing or closing due to formation pressure, and effectively maintaining the stability and flow conduction capacity of the perforation channel.

[0037] Example 2: Based on Example 1, such as Figure 5 and Figure 7As shown, it also includes a fusion mechanism 6, which comprises a metal heat-conducting ring 61 and a heat-conducting frame 62. The metal heat-conducting ring 61 is embedded in the outer side of the isolation cylinder 51, and the heat-conducting frame 62 is provided on the inner side of the isolation cylinder 51. The heat-conducting frame 62 is in contact with the nylon rope 584, and one end of the heat-conducting frame 62 passes through the isolation cylinder 51 and is connected to the inner wall of the metal heat-conducting ring 61. When the perforating projectile 3 is detonated, the generated high temperature is rapidly conducted to the metal heat-conducting ring 61, and then quickly transferred to the heat-conducting frame 62. Since the heat-conducting frame 62 is in direct contact with the nylon rope 584, its own temperature also rises under the influence of the temperature increase. The nylon rope 584 will undergo a process of softening, melting, and eventually breaking after being heated. When the temperature reaches the melting point of the nylon material (about 215-220℃), the nylon rope 584 begins to melt and loses its tension constraint on the connecting disc 53. At this time, the stored elastic potential energy of the spring 56 is released, pushing the connecting plate 53, the shape memory alloy bracket 54, and the guide rod 52 outward to complete the deployment of the support mechanism 5. This fuse mechanism 6 effectively compensates for the risk of the annular cutter 572 failing to trigger due to jamming or wear, thereby improving the reliability of the entire support mechanism 5.

[0038] Example 3: Based on Example 2, such as Figure 8 and Figure 9 As shown, the guide disc 55 has rifling helical grooves 7 evenly spaced circumferentially on the bore wall in the middle, and the guide rod 52 has a drive belt 8 evenly spaced circumferentially on the outer side, which is adapted to the rifling helical grooves 7. After the perforation operation is completed, the support mechanism 5 is triggered, and the energy storage spring 56 releases energy to push the guide rod 52 outward. At this time, the rifling helical grooves 7 on the outer wall of the guide rod 52 make contact with the drive belt 8 inside the isolation cylinder 51. As the guide rod 52 moves forward axially, the drive belt 8 is embedded in the rifling helical grooves 7 and generates a circumferential force under the guidance of the groove structure, thereby driving the guide rod 52 to start rotating. The connecting disc 53 and the shape memory alloy bracket 54 also rotate synchronously. The cylindrical part of the shape memory alloy bracket 54 rotates during the advancement process, and its front edge makes dynamic scraping contact with the inner wall of the perforation channel, effectively removing debris, deposits or other impurities attached to the inlet and inner wall of the channel, ensuring that the bracket enters smoothly and fits the channel. At the same time, it improves the centering and guidance of the bracket when entering the channel and prevents deflection and jamming.

[0039] like Figure 6As shown, a ball bearing 10 is installed at the end of the guide rod 52 facing the firing port of the perforated projectile 3. When the guide rod 52 enters the perforation channel, if its end contacts the inner wall of the channel, the ball bearing 10 will first contact the inner wall. Because the ball bearing 10 has excellent rolling properties, it can convert the sliding friction that might otherwise occur into rolling friction, thereby significantly reducing the resistance between the contact surfaces. Even if the guide rod 52 encounters local obstruction during its advance, the ball bearing 10 can still guide the guide rod 52 to continue advancing along the channel direction using its multi-directional rolling characteristics, avoiding jamming.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
