Description

Technical Field

[0001] This invention relates to the field of sucker rod technology, specifically to an electrically heated carbon fiber continuous sucker rod. Background Technology

[0002] Electrically heated carbon fiber continuous sucker rod is an oilfield production device that combines carbon fiber composite materials with electric heating technology. It is mainly used for heavy oil extraction, high-pour-point oil wells, and oil well production in low-temperature environments. Its core feature is that it directly heats the rod body with electrical energy, increasing the wellbore temperature and reducing crude oil viscosity, thus solving the problem of low efficiency of traditional sucker rods in special reservoirs.

[0003] Current electrically heated continuous sucker rods are often used as a single, long rod. However, the impact and stress of a single-piece sucker rod are concentrated during reciprocating motion, making it prone to breakage and affecting its service life. Furthermore, the electric heating of the sucker rod can only address the waxing of the oil on the rod surface at low temperatures. Impurities such as gums and inorganic salts in the oil can also easily adhere to the rod surface, causing severe scaling, which affects the rod's performance and service life. In addition, the existing method of using scrapers on the outside of the rod to remove scale can easily lead to wear on the carbon fiber rod over time, making it difficult to guarantee the effective service life of the rod.

[0004] To address the above issues, an electrically heated carbon fiber continuous sucker rod is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an electrically heated carbon fiber continuous sucker rod. By using this device, the problems mentioned above can be solved, such as the concentrated impact and high stress during the reciprocating motion of the integral sucker rod, which easily leads to rod breakage and affects the service life of the rod. At the same time, impurities such as colloids and inorganic salts in the oil can easily adhere to the surface of the rod, resulting in severe scaling, which also affects the performance and service life of the rod.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrically heated carbon fiber continuous sucker rod, comprising a main rod and a connecting rod disposed below the main rod, a connecting sleeve being sleeved between the main rod and the connecting rod, a limiting ring being fixed to the outer side of the upper end of the connecting rod, the connecting rod being rotatably connected to the connecting sleeve through the limiting ring, a toothed groove being circumferentially formed on the inner surface of the connecting sleeve, a guide rod being installed on the outer surface of the bottom of the main rod, and four sets of guide rods being circumferentially arranged around the main rod, the main rod being slidably connected to the toothed groove through the guide rods; A rotating mechanism is provided in the middle of the inner side of the connecting rod, and a mating mechanism is installed in the middle of the outer side of the rotating mechanism. A fitting seat is fixedly installed at one end of the mating mechanism, and one side surface of the fitting seat is in contact with the inner wall of the connecting rod.

[0007] Furthermore, the main body rod includes a sliding groove disposed behind the guide rod, and the sliding groove is formed on the main body rod. A sliding block is slidably disposed in the middle of the sliding groove, and one end of the sliding block is fixedly connected to one end of the guide rod.

[0008] Furthermore, the upper and lower ends of the sliding block are both fixed with support springs, and the sliding block is elastically connected to the sliding groove through the support springs.

[0009] Furthermore, the rotating mechanism includes a reciprocating lead screw located in the middle of the inner side of the connecting rod, and a support frame is provided on the outer side of the reciprocating lead screw, with both ends of the support frame fixed to the inner wall of the connecting rod.

[0010] Furthermore, a fixed plate is fixed to the top of the reciprocating lead screw, and a first magnetic ring is fixed to the outside of the fixed plate. A second magnetic ring is provided on the outside of the first magnetic ring, and the second magnetic ring is fixed to the inner wall of the connecting sleeve.

[0011] Furthermore, the mating mechanism includes a sliding ring threaded onto a reciprocating lead screw, with one end of the sliding ring fixedly connected to the mating seat.

[0012] Furthermore, the inner surfaces of both the main rod and the connecting rod are provided with moving grooves, and the fitting seat is slidably connected to the moving grooves.

[0013] Furthermore, a rotating ball is rotatably mounted on the outer surface of the limiting ring, and the limiting ring is slidably connected to the connecting sleeve through the rotating ball. A heating plate is fixed on the inner wall of both the main body rod and the connecting rod, and a transmission line is connected above the heating plate.

[0014] Furthermore, a conductive seat is fixed on the upper surface of the sliding ring, and a conductive slip ring is sleeved on the upper part of the conductive seat. The conductive slip ring is rotatably connected to the sliding ring, and the conductive slip ring is electrically connected to the conductive seat. The conductive seat is electrically connected to the mating seat. A connecting wire is connected above the conductive slip ring, and the connecting wire is electrically connected to the transmission line.

[0015] Furthermore, a plurality of guide vanes are fixed in a ring on the outer surface of the connecting sleeve, and a baffle is fixed on one side of the surface of the guide vanes.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention utilizes the reciprocating sliding capability between the main rod and the connecting sleeve to release stress, absorb the reciprocating impact force during oil pumping, reduce the fatigue stress of the entire rod directly subjected to force, and buffer the instantaneous impact and start-stop overload of the pumping unit, reducing the risk of rod joint pull-out and avoiding the problem of scrapping the entire rod. At the same time, the buffer joint formed between the main rod and the connecting rod and the connecting sleeve can compensate for the thermal expansion and contraction of the rod under subsequent electric heating, avoiding the problem of the entire long rod being prone to bending and deformation due to thermal stress.

[0017] 2. This invention utilizes the high-frequency vibration generated by the bonding seat to act on the surface of the connecting rod. This ultrasonic high-frequency vibration can break and peel off inorganic salt deposits, asphalt, and gum deposits on the outer surface of the rod, thus solving the problem of hard scale that cannot be removed by heating. At the same time, ultrasonic cleaning is used inside the rod to remove scale. While ensuring the effective cleaning of the outer surface of the rod, it does not cause mechanical scraping of the outer surface of the rod, thereby preventing wear and damage to the carbon fiber layer on the outer surface of the rod and improving the service life of the rod.

[0018] 3. This invention utilizes the non-contact transmission between the first and second magnetic rings, thereby reducing the possibility of vibration transmission to the reciprocating lead screw during the rotation of the connecting sleeve. This improves the stability of the reciprocating lead screw and the mating seat, ensuring the vibration effect of the mating seat itself. Furthermore, when the transmission line passes between the first and second magnetic rings, it does not interfere with the motion of the reciprocating lead screw during rotation. Simultaneously, the conductive slip ring can rotate relative to the sliding ring, thus preventing the connecting line from rotating with the sliding ring and preventing the connecting line from tangling, ensuring the stability of the rod body during use.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To address the technical problem of concentrated impact and high stress during reciprocating motion of integral sucker rods, which easily leads to rod breakage and thus affects the rod's service life, such as... Figure 1 - Figure 4 As shown, the following preferred technical solutions are provided: An electrically heated carbon fiber continuous sucker rod includes a main rod 1 and a connecting rod 2 disposed below the main rod 1. A connecting sleeve 3 is sleeved between the main rod 1 and the connecting rod 2. The main rod 1 and the connecting rod 2 have the same structure, both being existing hollow carbon fiber sucker rod bodies. The main rod 1 and the connecting rod 2 are connected in sections by the connecting sleeve 3, and after connection, the main rod 1 and the connecting rod 2 form a complete sucker rod. A limit ring 4 is fixed to the outer side of the upper end of the connecting rod 2. The connecting rod 2 is rotatably connected to the connecting sleeve 3 through the limit ring 4, and the rotation point of the connecting rod 2 and the connecting sleeve 3 is sealed, so that when the entire rod is installed in the oil well, leakage at the rotation point of the connecting rod 2 and the connecting sleeve 3 can be avoided.

[0023] The inner surface of the connecting sleeve 3 is provided with a toothed groove 5. The bottom outer surface of the main body rod 1 is provided with a guide rod 6, and four sets of guide rods 6 are arranged in a ring around the main body rod 1. The main body rod 1 is slidably connected to the toothed groove 5 through the guide rod 6. The main body rod 1 can slide up and down with the connecting sleeve 3 by means of the guide rod 6 and the toothed groove 5. The main body rod 1 and the connecting sleeve 3 are provided with a sliding seal, which can prevent leakage from the sliding part of the main body rod 1 and the connecting sleeve 3.

[0024] When the main rod 1 is performing continuous reciprocating pumping action, the guide rod 6 will squeeze the inclined surface of the toothed groove 5 as it slides up and down between the main rod 1 and the connecting sleeve 3, thus converting the up and down sliding of the main rod 1 and the connecting sleeve 3 with the cooperation of the limiting ring 4. This allows the connecting sleeve 3 to rotate radially in one direction along the limiting ring 4 on the connecting rod 2. When the main rod 1 is performing continuous reciprocating pumping action, the reciprocating sliding ability between the main rod 1 and the connecting sleeve 3 can release force, absorb the reciprocating impact force during pumping, reduce the fatigue stress of the entire rod directly subjected to force, and buffer the instantaneous impact and start-stop overload of the pumping unit, reducing the risk of rod joint pull-out and avoiding the problem of scrapping the entire rod. At the same time, the buffer joint formed between the main rod 1 and the connecting rod 2 and the connecting sleeve 3 can compensate for the thermal expansion and contraction of the rod under subsequent electric heating, avoiding the problem of bending and deformation of the entire long rod due to thermal stress.

[0025] like Figure 2 As shown, a rotating mechanism 7 is provided in the middle of the inner side of the connecting rod 2, and a mating mechanism 8 is installed in the middle of the outer side of the rotating mechanism 7. When the connecting sleeve 3 rotates radially in one direction on the connecting rod 2, the rotational force of the connecting sleeve 3 can be transmitted to drive the rotating mechanism 7 to rotate together, so that the rotating mechanism 7 can rotate radially in one direction within the connecting rod 2. The rotating mechanism 7 and the mating mechanism 8 are connected by a thread, so that when the rotating mechanism 7 rotates, under the action of the thread, the mating mechanism 8 can move along the rotating mechanism 7. A fitting seat 9 is fixedly installed at one end of the mating mechanism 8, and one side surface of the fitting seat 9 is in contact with the inner wall of the connecting rod 2. The fitting seat 9 is a miniature ultrasonic transducer based on existing principles, and the contact surface between the fitting seat 9 and the inner wall of the connecting rod 2 is set as an arc, and the contact end surface of the fitting seat 9 is made of wear-resistant material.

[0026] When the mating mechanism 8 moves along the rotating mechanism 7, it synchronously drives the mating seat 9 to move as well, allowing the mating seat 9 to move along the inner wall of the connecting rod 2. The high-frequency vibration generated by the mating seat 9 of the ultrasonic transducer acts on the surface of the connecting rod 2, causing the ultrasonic high-frequency vibration to break and peel away inorganic salt deposits, asphalt, and gum deposits on the outer surface of the rod. This solves the problem of hard scale that cannot be removed by heating. Simultaneously, ultrasonic descaling is performed inside the rod, ensuring effective descaling of the outer surface without mechanically scraping it, thus preventing wear and damage to the carbon fiber layer on the outer surface. Furthermore, since the main rod 1 and connecting rod 2 have the same structure, and the ends of multiple sections of the main rod 1 and connecting rod 2 are connected by connecting sleeves 3, each section of the main rod 1 and connecting rod 2 is equipped with a rotating mechanism 7, a mating mechanism 8, and a mating seat 9. This ensures that the entire rod interior is treated for hard scale deposits, guaranteeing the overall performance of the sucker rod.

[0027] like Figure 4 As shown, the main body rod 1 includes a sliding groove 11 disposed behind the guide rod 6, and the sliding groove 11 is opened on the main body rod 1. A sliding block 12 is slidably disposed in the middle of the sliding groove 11, and one end of the sliding block 12 is fixedly connected to one end of the guide rod 6. The guide rod 6 and the sliding block 12 can slide up and down in the sliding groove 11.

[0028] Support springs 13 are fixed at both the upper and lower ends of the sliding block 12. The support springs 13 are made of hard and fatigue-resistant metal, which can meet the force of the rod during oil extraction. The sliding block 12 is elastically connected to the sliding groove 11 through the support springs 13. The guide rod 6 and the sliding block 12 can move up and down elastically on the main rod 1 through the support springs 13. When the main rod 1 slides up and down in the toothed groove 5 using the guide rod 6, when the guide rod 6 moves to the upper and lower ends of the toothed groove 5, the support springs 13 fixed at the upper and lower ends of the sliding block 12 can buffer the excess force when the main rod 1 and the guide rod 6 move up and down. Thus, during the instantaneous impact of oil extraction and the overload of start-stop, the support springs 13 can buffer and absorb the force on the guide rod 6 and the entire oil rod, which helps to further improve the protection of the rod and avoid the problem of the entire rod being easily scrapped due to long-term direct force.

[0029] To address the technical issue of impurities such as gum and inorganic salts in the oil easily adhering to the surface of the rod, causing severe scaling and affecting its performance and lifespan, such as... Figure 2 - Figure 8 As shown, the following preferred technical solutions are provided: like Figure 5 As shown, the rotating mechanism 7 includes a reciprocating lead screw 71 disposed in the middle of the inner side of the connecting rod 2, and a support frame 72 disposed on the outer side of the reciprocating lead screw 71. The two ends of the support frame 72 are fixed on the inner wall of the connecting rod 2. The reciprocating lead screw 71 is disposed in the middle of the connecting rod 2 by means of the support frame 72, and the reciprocating lead screw 71 and the support frame 72 can rotate.

[0030] A fixed plate 73 is fixed to the top of the reciprocating screw 71, and a first magnetic ring 74 is fixed to the outside of the fixed plate 73. A second magnetic ring 75 is provided on the outside of the first magnetic ring 74, and the second magnetic ring 75 is fixed to the inner wall of the connecting sleeve 3. Alternating strong magnetic poles are evenly distributed on the first magnetic ring 74 and the second magnetic ring 75, forming a magnetic coupling based on the existing principle. When the connecting sleeve 3 drives the second magnetic ring 75 to rotate, the torque is transmitted through synchronous push and pull by the attraction of opposite poles and the repulsion of like poles. This allows the second magnetic ring 75 to drive the first magnetic ring 74 to rotate in the air, thereby transmitting the rotational force of the connecting sleeve 3 to the reciprocating screw 71, so that the reciprocating screw 71 can rotate together with the connecting sleeve 3.

[0031] like Figure 7 As shown, the mating mechanism 8 includes a sliding ring 81 threadedly connected to the reciprocating screw 71. One end of the sliding ring 81 is fixedly connected to the mating seat 9. When the reciprocating screw 71 is finally rotated by the connecting sleeve 3, the threaded force between the reciprocating screw 71 and the sliding ring 81 allows the sliding ring 81 to drive the mating seat 9 to move back and forth on the surface of the reciprocating screw 71. Since one side surface of the mating seat 9 is in contact with the inner wall of the connecting rod 2, and the mating seat 9 is a miniature ultrasonic transducer based on existing principles, when the mating seat 9 moves, the high-frequency vibration of the ultrasonic waves can break and peel the inorganic salts on the outer surface of the rod. Hard deposits such as scale, asphalt, and gum can be removed by heating, thus solving the problem of hard scale that cannot be removed by heating. This helps to ensure the stability of the rod during operation, reduce the load and stress on the rod, and reduce the probability of fatigue fracture. This is beneficial to improving the stability and lifespan of the carbon fiber continuous sucker rod. At the same time, the rotation of the reciprocating screw 71 is transmitted non-contactly through the first magnetic ring 74 and the second magnetic ring 75, which reduces the possibility of vibration being transmitted to the reciprocating screw 71 when the connecting sleeve 3 rotates. This helps to improve the stability of the reciprocating screw 71 and the mating seat 9, and ensures the vibration effect of the mating seat 9 itself.

[0032] To address the issues of motion interference during conductive heating and vibration within the rod, and the technical problem of oil accumulation on the rod surface due to external flow, such as... Figure 2 - Figure 7 As shown, the following preferred technical solutions are provided: like Figure 2 and Figure 5 As shown, both the inner surfaces of the main rod 1 and the connecting rod 2 are provided with moving grooves 10, and the fitting seat 9 is slidably connected to the moving grooves 10. When the sliding ring 81 drives the fitting seat 9 to move up and down on the surface of the reciprocating screw 71, the friction between the sliding ring 81 and the reciprocating screw 71 will cause the sliding ring 81 and the fitting seat 9 to rotate together with the reciprocating screw 71. The movement trajectory of the moving groove 10 is the same as the movement trajectory of the fitting seat 9 moving up and down with the reciprocating screw 71. Thus, when the fitting seat 9 performs ultrasonic high-frequency vibration descaling, it can realize the dynamic vibration peeling of the rod body, thereby improving the vibration effect and coverage area of ​​the fitting seat 9 on the rod body. This helps to reduce the dead corners of descaling and makes the overall descaling efficiency higher.

[0033] A rotating ball bearing 40 is rotatably mounted on the outer surface of the limiting ring 4, and the limiting ring 4 is slidably connected to the connecting sleeve 3 through the rotating ball bearing 40. When the connecting sleeve 3 rotates at the upper limit of the connecting rod 2 using the limiting ring 4, the rotating ball bearing 40 between the limiting ring 4 and the connecting sleeve 3 can reduce the friction between the limiting ring 4 and the connecting sleeve 3 during rotation, thereby improving the smoothness of the rotation of the connecting sleeve 3, ensuring the long-term rotation effect of the connecting sleeve 3, and the effect of rotation transmission. Heating plates 50 are fixed on the inner walls of both the main rod 1 and the connecting rod 2, and a transmission device is connected above the heating plates 50. The transmission line 60 is positioned between the main body rod 1 and the connecting rod 2, and has a certain length and elasticity, enabling the transmission line 60 to meet the vertical movement requirements between the main body rod 1 and the connecting rod 2. At the same time, the input end of the transmission line 60 is connected to an existing control device outside the rod, allowing the heating plate 50 to be energized and heated, thereby heating the entire rod to prevent the possibility of wax buildup on the rod surface. Meanwhile, the non-contact transmission between the first magnetic ring 74 and the second magnetic ring 75 ensures that when the transmission line 60 passes through the middle, there will be no motion interference when the reciprocating lead screw 71 rotates.

[0034] like Figure 7 As shown, a conductive seat 82 is fixed to the upper surface of the sliding ring 81, and a conductive slip ring 83 is sleeved on the upper part of the conductive seat 82. The conductive slip ring 83 is rotatably connected to the sliding ring 81, and the conductive slip ring 83 is electrically connected to the conductive seat 82. The conductive seat 82 is electrically connected to the mating seat 9. A connecting wire 84 is connected to the upper part of the conductive slip ring 83. The connecting wire 84 has a certain length and rigidity, and the middle part of the connecting wire 84 is spirally arranged. By folding and stretching the spiral part of the connecting wire 84, it can adapt to the height change when the sliding ring 81 moves up and down. The connecting wire 84 is electrically connected to the transmission line 60, and the power of the transmission line 60 is... By utilizing the transmission of power through the connecting wire 84, the conductive slip ring 83, and the conductive seat 82, power can ultimately be supplied to the mating seat 9. The conductive slip ring 83 and the conductive seat 82 can rotate. Thus, when the sliding ring 81 rotates relative to the reciprocating screw 71, the rigidity of the connecting wire 84 supports the conductive slip ring 83 due to the rotational capability of the conductive slip ring 83. Furthermore, the middle spiral part of the connecting wire 84 does not rotate with the connecting wire 84 during rotation, allowing the conductive slip ring 83 to rotate relative to the sliding ring 81. This prevents the connecting wire 84 from rotating with the sliding ring 81 and thus prevents the connecting wire 84 from becoming entangled.

[0035] like Figure 3As shown, several guide vanes 20 are fixed in a ring on the outer surface of the connecting sleeve 3, and a baffle plate 30 is fixed on one side of the surface of the guide vanes 20. When the connecting sleeve 3 rotates, it can drive the guide vanes 20 and the baffle plate 30 to rotate together. When the guide vanes 20 and the baffle plate 30 rotate, they will generate a centrifugal swing effect. Thus, when the oil flows out of the connecting sleeve 3, the centrifugal force generated by the guide vanes 20 can swing the oil outward towards the outside of the rod, which helps to reduce the possibility of oil and impurities in the oil adhering and depositing along the rod, reduce the operating load and frictional resistance of the rod, reduce the frequency of wax removal operations, improve the efficiency of electric heating and ultrasonic descaling, and extend the service life of the sucker rod.
