Technical Field
[0001] The invention relates to the technical field of blockage removal and oil production increase, and in particular to a SXW self-adaptive intelligent negative pressure vibration blockage removal and oil production increase device. Background Art
[0002] SXW adaptive intelligent negative pressure vibration unblocking and oil-increasing device is an innovative device that combines negative pressure, vibration technology and intelligent control system. It is designed to solve the problem of poor oil flow caused by solid particle blockage in oil and gas pipelines or oil wells. The device monitors the fluid state in the pipeline in real time through an intelligent sensing system, automatically adjusts the negative pressure and vibration frequency, and effectively removes the blockage.
[0003] A Chinese patent with patent announcement number CN118933629A discloses an underground integrated negative pressure plugging and oil booster for petroleum production, including a vibrating part, an oil layer casing is sleeved on the outside of the vibrating part, a counterweight oil pipe is arranged at the bottom of the vibrating part, the vibrating part is connected to a piston shell, a pressurizing part is arranged on the piston shell, a screen pipe is connected to the top of the pressurizing part, and elastic pistons are arranged at both ends of the pressurizing part. When the piston shell moves downward, the lower elastic piston is closed, and the well fluid is used to push the vibrating part upward to generate gravitational potential energy, which is opened through the oil-repelling hole in the lower elastic piston, and the oil-repelling hole in the upper elastic piston is closed. The elastic piston generates suction when it moves upward to form a negative pressure in the near-wellbore area, and when the piston rod falls back, a closed space is formed at the bottom of the upper elastic piston, which prompts a small amount of well fluid to be reinjected along the oil-repelling hole, thereby playing the role of flushing the channel and improving the permeability of the rock formation, thereby ensuring the effect of oil production.
[0004] However, the negative pressure vibration unblocking and oil-increasing device currently has the following problems: Since the working principle of the negative pressure vibration unblocking device is to unblock by vibration, as the equipment is used for a longer time, the connection between the screen pipe of the negative pressure vibration unblocking device and the oil pump will suffer from wear. Wear makes the connection of the device looser and increases the probability of falling off, especially when unblocking operations are performed frequently. Therefore, we proposed the SXW adaptive intelligent negative pressure vibration unblocking and oil-increasing device. Summary of the invention
[0005] In view of the deficiencies in the prior art, the present invention provides a SXW self-adaptive intelligent negative pressure vibration blockage removal and oil-increasing device, which solves the problems raised in the above-mentioned background technology.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an SXW self-adaptive intelligent negative pressure vibration unblocking and oil-increasing device comprises an oil pump, an inner wall of the oil pump is provided with an oil pump plunger, a bottom of the oil pump is threadedly connected to a screen pipe, an outer wall of the screen pipe is provided with a plurality of screen holes, a mechanical unblocking oil extractor is provided at the bottom of the screen pipe, a soft metal wire plug is threadedly connected to the bottom of the mechanical unblocking oil extractor, an anti-breaking device is provided below the outer wall of the screen pipe, the anti-breaking device comprises a fixed ring frame, an inner wall of the fixed ring frame is fixedly connected to the lower part of the outer wall of the screen pipe, a plurality of grooves are provided above the outer wall of the fixed ring frame, the inner walls of the plurality of grooves are fixedly connected to elastic telescopic plates, and the telescopic ends of the plurality of elastic telescopic plates are A stabilizing plate is fixedly connected, and a side of the plurality of stabilizing plates close to the elastic telescopic plate is fixedly connected with a contact plate 1, the bottom of the inner wall of the plurality of fixing ring frame grooves is fixedly connected with an electric push rod, the telescopic ends of the plurality of electric push rods are fixedly connected with a fixing block, the sides of the plurality of fixing blocks are fixedly connected with the same fixing ring, the top of the fixing ring is fixedly connected with a plurality of U-shaped contact plates, the mechanical unblocking oil extractor comprises a forward elastic piston, the top of the forward elastic piston is threadedly connected to the bottom of the screen pipe, the bottom of the forward elastic piston is threadedly connected with a reverse elastic piston, the bottom of the reverse elastic piston is threadedly connected with a vibrating disk, a counterweight oil pipe is slidably connected to the lower part of the outer wall of the vibrating disk, and the inner wall of the counterweight oil pipe is fixedly connected with a T shaped connecting rod, a piston B is fixedly connected to the upper outer wall of the T-shaped connecting rod, a piston A is fixedly connected to the top of the T-shaped connecting rod, a top side of the plurality of U-shaped contact plates is set to an arc shape, a bottom side of the plurality of contact plates is set to an arc shape, one arc-shaped side of the contact plate is located on the displacement track of the arc-shaped side of the U-shaped contact plate, a plurality of electric push rods are electrically connected to an external controller, when the oil pump plunger in the oil pump moves downward, the oil pipe column is loaded with elastic elongation, driving the oil extractor to move downward, at this time, since the reverse elastic piston of the oil extractor blocks the annular space of the oil casing, the downward movement of the oil extractor is bound to squeeze the lower well fluid, forcing the pressurized well fluid to be ejected upward through the central flow channel of the reverse elastic piston, pushing the piston B upward, causing the counterweight oil pipe and the vibration The disc moves upward, storing gravitational potential energy. When it moves to the limiter, it collides and generates vibration waves. After the elastic extension of the oil pipe string ends, the oil extractor stops moving downward, and the injection impact force disappears. Therefore, the counterweight oil pipe and vibration disc in the upper position fall down by their own weight, releasing the gravitational potential energy and generating kinetic energy. When they fall to the limiter, they collide and generate vibration waves. When the counterweight oil pipe falls, it drives piston A downward, forming a low-pressure area above piston A, promoting and forming negative pressure, generating suction effect, and the well fluid pushed upward enters the throat through the spiral flow channel to increase pressure and speed. The impact liquid whistle reed makes a sound, generates ultrasonic waves, and continues to act on the oil layer outside the vibration source. When the oil pump plunger moves upward, the oil pipe string is unloaded and shrinks, driving the oil extractor to move upward. At this time, the positive check valve is closed.The positive elastic piston of the oil extractor blocks all the oil passages. The upward movement of the oil extractor will inevitably suck the lower well fluid, so that negative pressure is formed at the bottom of the well again. The two suction effects are superimposed, which further ensures the effect of the suction force. At this point, a pulsation cycle is completed; since the working principle of the negative pressure vibration unblocking device is to unblock by vibration, as the use time of the equipment increases, the connection between the screen pipe of the negative pressure vibration unblocking device and the oil pump will suffer from wear, and the wear makes the connection of the device looser and increases the probability of falling off, especially in the case of frequent unblocking operations. Therefore, when the negative pressure vibration unblocking device is placed in the oil well When the oil pipe is moved, multiple electric push rods are started through an external controller, and the telescopic ends of the multiple electric push rods will move upward and push the multiple fixed blocks upward at the same time. The upward movement of the multiple fixed blocks will drive the same fixed ring to move upward, and the upward movement of the fixed ring will drive the U-shaped contact plate to move upward. The movement of the U-shaped contact plate will contact the contact plate 1, so that the contact plate 1 moves away from the screen pipe. The movement of the contact plate 1 will drive the stabilizing plate to contact the inner wall of the oil well. At the same time, the movement of the stabilizing plate will stretch the elastic telescopic plate. The stabilizing plate will contact the inner wall of the oil well to strengthen the fixation of the screen pipe.

Through the arrangement of the above structure, the rotation of the connecting block 512 will drive the triangular scraper 513 to remove the oil stains on the inner wall of the oil well where the stabilizing plate 53 is fixed, so as to avoid the influence of oil stains on the stabilizing plate 53, which makes it difficult for the stabilizing plate 53 to stably unblock the oil-increasing device.
[0020] An anti-loosening device 6 is provided at the top of the outer wall of the fixed ring frame 51, and the anti-loosening device 6 includes a cavity box 61, the bottom of the cavity box 61 is fixedly connected to the top of the outer wall of the fixed ring frame 51, and two short rods 62 are passed through and slidably connected to the top of the cavity box 61, and the bottoms of the two short rods 62 are fixedly connected to the same movable plate 63, and the tops of the two short rods 62 are fixedly connected to the bottom of the fixed ring 57, and a hose 64 is fixedly connected to the lower part of the outer wall of the cavity box 61, and one end of the hose 64 away from the cavity box 61 is fixedly connected to a suction plate 65, and the outer wall of the suction plate 65 is fixedly connected to the inner wall of the stabilizing plate 53. Through the arrangement of the above structure, the upward movement of the short rod 62 will drive the movable plate 63 to move inside the cavity box 61, so that the air at the suction port of the suction plate 65 is extracted through the hose 64, so that when the suction plate 65 contacts the inner wall of the oil well, the suction plate 65 can be adsorbed on the inner wall of the oil well, thereby enhancing the stabilizing effect of the stabilizing plate 53.
[0021] The anti-loosening device 6 also includes two vertical rods 66, the tops of the two vertical rods 66 are fixedly connected to the bottom of the stabilizing plate 53, the bottoms of the two vertical rods 66 are fixedly connected with arc plates 67, the tops of the two arc plates 67 are fixedly connected with connecting plates 68, the sides of the connecting plates 68 are fixedly connected with fixed rings 69, the inner walls of the fixed rings 69 are fixedly connected to the outer walls of the hoses 64, through the arrangement of the above structure, the arc plates 67 will divert the oil flowing upward inside the oil well to prevent the oil from frequently contacting the stabilizing blocks, resulting in reduced stability of the stabilizing plate 53, the movement of the fixed rings 69 drives the hose 64 to move, thereby fixing the hose 64 at a certain position, thereby preventing the hose 64 from being damaged due to hanging.
[0022] When in use, when the oil pump plunger in the oil pump 1 moves downward, the oil pipe string is loaded with elastic extension, driving the oil extractor to move downward. At this time, since the reverse elastic piston 32 of the oil extractor blocks the annular space of the oil casing, the downward movement of the oil extractor is bound to squeeze the lower well fluid, forcing the pressurized well fluid to spray upward through the central flow channel of the reverse elastic piston 32, pushing the piston B36 upward, causing the counterweight oil pipe 34 and the vibration plate 33 to move upward, storing gravitational potential energy, and colliding when moving up to the limiter, generating vibration waves. After the elastic extension of the oil pipe string ends, the oil extractor stops moving downward, and then the injection impact force disappears. Therefore, the counterweight oil pipe 34 and the vibration plate 33 in the upper position are close to each other. The piston A37 is driven downward by the weight of the piston 37, so that a low-pressure area is formed above the piston A37, which promotes and forms a negative pressure, and produces a suction effect. The well fluid pushed upward enters the throat through the spiral flow channel and increases pressure and speed. The impact liquid whistle reed makes a sound, generates ultrasonic waves, and continues to act on the oil layer outside the vibration source. When the oil pump plunger moves upward, the oil pipe string is unloaded and shrinks, driving the oil extractor to move upward. At this time, the positive check valve is closed, and the positive elastic piston 31 of the oil extractor blocks all oil channels. The upward movement of the oil extractor is bound to suck the lower well fluid, so that the bottom of the well can be re-activated. The negative pressure is formed twice, and the two suction effects are superimposed, which further ensures the effect of the suction force. At this point, a pulsation cycle is completed. Since the working principle of the negative pressure vibration unblocking device is to unblock by vibration, as the use time of the equipment increases, the connection between the screen pipe 2 of the negative pressure vibration unblocking device and the oil pump 1 will suffer from wear. The wear makes the connection of the device looser and increases the probability of falling off, especially in the case of frequent unblocking operations. Therefore, when the negative pressure vibration unblocking device is placed inside the oil well, multiple electric push rods 55 are started through an external controller, and the telescopic ends of the multiple electric push rods 55 will move upward and simultaneously push multiple fixed The block 56 moves upward, and the upward movement of the multiple fixed blocks 56 will drive the same fixed ring 57 to move upward. The upward movement of the fixed ring 57 drives the U-shaped contact plate 58 to move upward. The movement of the U-shaped contact plate 58 will contact the contact plate 1 54, so that the contact plate 1 54 moves away from the screen pipe 2. The movement of the contact plate 1 54 will drive the stabilizing plate 53 to contact the inner wall of the oil well. At the same time, the movement of the stabilizing plate 53 will stretch the elastic expansion plate 52. The stabilizing plate 53 contacts the inner wall of the oil well to strengthen the fixation of the screen pipe 2, thereby reducing the problem of disconnection between the screen pipe 2 and the oil pump 1 when frequent unblocking operations are performed;The movement of the contact plate 54 drives the support rod 510 to move, and the movement of the support rod 510 drives the gear 511 to move. When the gear 511 moves with the position of the side teeth of the L-shaped block 59, the gear 511 and the teeth are meshed with each other, so that the gear 511 rotates, and the rotation of the gear 511 drives the connecting block 512 to rotate. The rotation of the connecting block 512 moves along the inner wall of the track of the U-shaped track block 515 through the round block 514. The rotation of the connecting block 512 drives the triangular scraper 513 to remove the oil stains on the inner wall of the oil well where the stabilizing plate 53 is fixed, so as to avoid the oil stains affecting the stabilizing plate 53, which makes it difficult for the stabilizing plate 53 to stably unblock the oil-increasing device.
[0023] When the stabilizing plate 53 contacts the inner wall of the oil well, the stabilizing plate 53 drives the suction plate 65 to contact the inner wall of the oil well. At the same time, the upward movement of the fixing ring 57 drives the short rod 62 to move upward. The upward movement of the short rod 62 drives the moving plate 63 to move inside the cavity box 61, so that the air at the suction port of the suction plate 65 is extracted through the hose 64, so that when the suction plate 65 contacts the inner wall of the oil well, the suction plate 65 can be adsorbed on the inner wall of the oil well, thereby enhancing the stabilizing effect of the stabilizing plate 53. When the stabilizing plate 53 moves, the stabilizing plate 53 3 will drive the vertical rod 66 to move, and the movement of the vertical rod 66 will drive the arc plate 67 to move, and the arc plate 67 will divert the oil flowing upward inside the oil well to prevent the oil from frequently contacting the stabilizing block, resulting in reduced stability of the stabilizing plate 53; at the same time, the movement of the arc plate 67 will drive the connecting plate 68 to move, and the movement of the connecting plate 68 will drive the fixed ring 69 to move, and the movement of the fixed ring 69 will drive the hose 64 to move, so as to fix the hose 64 at a certain position, thereby avoiding the problem of damage to the hose 64 due to hanging.

Through the arrangement of the above structure, the movement of the T-shaped push rods 72 will push away the solid particles blocked in the sieve holes of the screen tube 2, thereby preventing the solid particles from adhering to the inner wall of the sieve holes of the screen tube 2 for a long time, resulting in the problem that the negative pressure vibration unblocking and oil-increasing device cannot vibrate the solid particles down through its own vibration when used next time, thereby restricting the flow channel of oil and gas, resulting in a decrease in oil and gas flow, resulting in a decrease in oil production of the oil well, and affecting production efficiency.
[0025] The anti-clogging device 7 also includes a limit plate 73, the side of the limit plate 73 is fixedly connected to the side of the L-shaped block 59, the side of the limit plate 73 is fixedly connected to a support ring 74, the outer wall of the T-shaped push rod 72 is provided with a spiral groove 75, and the inner wall of the support ring 74 is fixed with a slider for sliding installation inside the spiral groove 75. Through the setting of the above structure, the spiral groove 75 will drive the T-shaped push rod 72 to rotate, and the rotation of the T-shaped push rod 72 can push the solid particles more smoothly, thereby effectively avoiding the problem of oil stains adhering to the surface of the solid particles and the inner wall of the sieve hole of the sieve tube 2, which causes difficulty in pushing.
[0026] During use, after the negative pressure vibration unblocking and oil-increasing device is used, multiple electric push rods 55 are started through an external controller, and the telescopic ends of the multiple electric push rods 55 will move downward and simultaneously drive multiple fixed blocks 56 to move downward, and the downward movement of multiple fixed blocks 56 will drive the same fixed ring 57 to move downward, and the downward movement of the fixed ring 57 drives the U-shaped resistance plate 58 to move downward, and the movement of the U-shaped resistance plate 58 will move away from the resistance plate 1 54, and under the elastic force of the elastic telescopic plate 52 itself, the stabilizing plate 53 drives the resistance plate 1 54 to move in the direction of the screen tube 2, and the movement of the stabilizing plate 53 will drive the L-shaped plate 71 to move, and the movement of the L-shaped plate 71 drives the T-shaped push rod 72 to move, and the movement of the T-shaped push rod 72 will remove the blockage in The solid particles in the sieve holes of the sieve tube 2 are pushed away, thereby preventing the solid particles from adhering to the inner wall of the sieve holes of the sieve tube 2 for a long time, resulting in the problem that the negative pressure vibration unblocking and oil-increasing device cannot vibrate the solid particles down through its own vibration when used next time, thereby restricting the flow channel of oil and gas, resulting in a decrease in the oil and gas flow rate, resulting in a decrease in the oil production of the oil well, affecting production efficiency; at the same time, the movement of the T-shaped push rod 72 will drive the spiral groove 75 to move, and the spiral groove 75 will move along the outer wall of the slider of the support ring 74 when moving, so the spiral groove 75 will drive the T-shaped push rod 72 to rotate, and the rotation of the T-shaped push rod 72 can push the solid particles more smoothly, thereby effectively avoiding the problem of difficulty in pushing caused by oil stains adhering to the surface of the solid particles and the inner wall of the sieve holes of the sieve tube 2.
