Description

Technical Field

[0001] The utility model relates to the technical field of oil drilling, in particular to a carbon fiber reinforced metal sucker rod processing device. Background Art

[0002] The sucker rod is a slender rod in a well pumping rig. It connects the polished rod at the top and the oil pump at the bottom, transmitting power. The wear resistance and corrosion resistance of the sucker rod determine and influence the operating life of the entire pumping equipment. Sucker rods are generally made of low- to medium-carbon alloy steel that has been quenched and tempered. They are connected one by one with couplings within the oil pipe and extend to the piston rod of the downhole oil pump, pumping oil through reciprocating motion.

[0003] As the oilfield enters the middle and late stages of development, the comprehensive water content is getting higher and higher, and water injection and other production-increasing measures are often used. In addition, the oilfield reinjection water is basically sewage directly reinjected, resulting in a very harsh working environment for the pumping rod. Highly mineralized well fluids contain various corrosive media and corrosive microorganisms, especially those rich in Cl - , which greatly increases the corrosion rate of the polished rod. At the same time, the associated gas contains corrosive gases such as CO2 and H2S, which make the well fluid weakly acidic. As we all know, the treatment of Cl - Corrosion caused by CO2, H2S, and other pollutants has always been a global challenge in oil production. Furthermore, friction between the sucker rod and the inner wall of the tubing generates heat, activating the rod surface. Under the influence of corrosive produced fluids, the corrosion rate of the sucker rod surface is significantly accelerated. Furthermore, factors such as sand content, wax and scale buildup in the well, and produced fluid viscosity can also contribute to corrosion and eccentric wear on the sucker rod surface.

[0004] Sucker rods are subjected to constant asymmetric alternating loads and the combined effects of oil, gas, water, and corrosive media, making them extremely unreliable equipment in mechanical oil production. Effectively managing corrosion and eccentric wear in sucker rods has become a pressing task for achieving efficient and stable production in the mid-to-late stages of oilfield development. According to statistics, surface failures account for over 90% of all sucker rod failures, and these failures can also lead to fracture failures, significantly complicating on-site management.

[0005] In order to solve the problem of corrosion resistance and wear resistance, the conventional prevention and control measures currently taken for sucker rods mainly use electroplating or chemical plating methods and technologies to process chrome-plated sucker rods, nickel-plated sucker rods, tungsten-plated sucker rods and spray-welded sucker rods.

[0006] The conventional wear-resistant and anti-corrosion coating of the sucker rod has low bonding strength with the substrate. When used in the above-mentioned complex well and mining environment, the coating is prone to peeling, falling off, and wearing, forming a shortcoming in corrosion and wear resistance. The effect is not very ideal, and the cost is relatively high. The spray-welded coating of the spray-welded sucker rod has greatly improved bonding strength with the substrate, and has good corrosion and wear resistance. However, the rod body needs to undergo secondary solid solution strengthening after spray-welding the anti-corrosion alloy coating. High temperature will substantially reduce the substrate performance of the spray-welded sucker rod, thereby substantially reducing the overall fatigue resistance and reliability of the sucker rod, and the cost is relatively high.

[0007] In order to better solve the corrosion and wear resistance problems of sucker rods, the inventor conducted in-depth research on the anti-corrosion and anti-eccentric wear technology of sucker rods, and finally effectively improved the overall corrosion resistance and anti-eccentric wear performance of the sucker rods through carbon fiber coating technology, with a high cost performance.

[0008] Carbon fiber refers to high-strength, high-modulus fibers with a carbon content of over 90%. It boasts the highest heat resistance of all chemical fibers. Made from acrylic and viscose fibers through high-temperature cracking and carbonization, it is a high-end material used in aerospace and other applications. Carbon fiber is a new generation of reinforcing fiber, known as the "king of new materials" and "black gold." It possesses excellent mechanical properties and chemical stability. Its specific gravity is less than one-quarter that of steel, yet its strength is 6 to 10 times that of steel. It also features low density, resistance to corrosion, high temperatures, friction, fatigue, low thermal and moisture expansion coefficients, and excellent durability.

[0009] When sucker rods are used in oil wells for extended periods, oil and rust accumulate on their outer surfaces, corroding the rod body and increasing friction between the rod and the sealing box. When pulled from the well, the oil on the outer surface of conventional sucker rods easily drips onto the well site, wasting crude oil, polluting the environment, and affecting operational efficiency and strength. Carbon fiber-coated sucker rods offer excellent corrosion resistance and strong anti-adhesion properties, along with a low friction coefficient and self-lubrication. These properties effectively reduce oil and rust on the rod string surface, slow wax deposition on the rod string surface, and minimize the occurrence of bare rod breakage in corrosive environments, offering a highly cost-effective solution.

[0010] During the carbon fiber coating process for sucker rods, the carbon fibers are first stretched and tensioned, soaked in liquid resin, and then squeezed through the resin before being wrapped around the rod. During the wrapping process, the rod's ends are clamped, tensioned, and rotated, and the carbon fiber wrapping device is then moved back and forth to coat the rod. Currently, there is no commercially available equipment capable of carbon fiber coating on sucker rods.

[0011] In view of this, the utility model provides a carbon fiber reinforced metal sucker rod processing device, which can realize the tensioning and rotation of the sucker rod, and can realize the carbon fiber soaking and extruding resin, and reciprocatingly wrap the carbon fiber wire around the outside of the sucker rod to form a carbon fiber anti-corrosion layer on the surface of the sucker rod, thereby extending the service life of the sucker rod, reducing the cost of oil well repair operations, and improving the economic benefits of the oil field.

[0034] In this embodiment, the winding device body 2 is located behind the tensioning and rotating device body 1. During operation, the sucker rod 17 is first clamped and fixed by the chuck 12. The sucker rod 17 is then tensioned by the tensioning device to prevent the middle portion of the sucker rod 17 from bending downward during the winding of the carbon fiber wire. The carbon fiber wire 19 is processed by the carbon fiber processing box 22, where it is tensioned, impregnated with resin, and flattened before being wound around one end of the sucker rod 17. The sucker rod 17 is then rotated by the rotating device. Simultaneously, the carbon fiber processing box 22 is driven left and right by the translational drive device, allowing the carbon fiber to be wrapped around the outside of the sucker rod 17. This completes the winding of the carbon fiber wire 29 and the plastic film encapsulation of the sucker rod 17. After the carbon fiber wrapping is completed, the rotating device is stopped, the sucker rod 17 is appropriately relaxed by the tensioning device, and the chuck 12 is then released from the sucker rod 17, allowing it to be removed and entered the next processing step.

[0035] This embodiment provides a carbon fiber reinforced metal sucker rod processing device, which can realize the tensioning and rotation of the sucker rod, and can realize the carbon fiber soaking and extruding resin, and reciprocatingly wrap the carbon fiber wire around the outside of the sucker rod to form a carbon fiber anti-corrosion layer on the surface of the sucker rod, thereby extending the service life of the sucker rod, reducing the cost of oil well repair operations, and improving the economic benefits of the oil field.

[0036] Example 2:

[0038] In this embodiment, the main machine bed 11 is welded from a combination of profiles and steel plates and fixed to the ground, possessing sufficient rigidity and strength. During operation, the spacing between the two rotating shafts 141 is adjusted by a tensioning device to accommodate the length of the sucker rod 17. The left and right ends of the sucker rod 17 are clamped and fixed by the chuck 12. The spacing between the rotating shafts 141 at both ends of the sucker rod 17 is increased by the tensioning device, thereby causing the chuck 12 to stretch the left and right ends of the sucker rod 17, thereby tightening the sucker rod 17 and preventing the middle portion of the sucker rod 17 from bending downward. The end of the carbon fiber on the winding device body is fixed to one end of the sucker rod 17, and then the sucker rod 17 is rotated by the rotating device.

After carbon fiber coating is complete, the rotating device stops rotating, and the sucker rod 17 is appropriately loosened using the tensioning device. The chuck 12 then releases the sucker rod 17, allowing it to be removed and moved to the next processing step. The adjustable spacing between the two rotating shafts 141 not only accommodates the processing of sucker rods 17 of varying lengths, but also allows for tensioning of the sucker rod 17.

During operation, two strands of carbon fiber are pulled from the winding device body and fixed to the ends of the two sucker rods 17. The rotating device then drives the sucker rods 17 to rotate, while the translation device simultaneously drives the winding device body to move left and right, so that the carbon fiber is wrapped around the outside of the two sucker rods 17. This improves the efficiency of carbon fiber wrapping of the sucker rods.

[0041] Furthermore, the rotating device includes a servo motor 142 , which is installed on the right side of the rotating shaft 141 at the right end of the main machine bed 11 , and an output end of the servo motor 142 is fixedly connected to the rotating shaft 141 .

[0045] In this embodiment, the chuck 12 is installed on the chuck mounting plate. The size of the chuck mounting plate is larger than the size of the fixed sleeve 145. The stretching plug 146 is used to limit the rotating shaft 141 within the fixed sleeve 145, thereby limiting the left and right movement of the stretching plug 146 relative to the fixed sleeve 145.

[0046] Furthermore, a left headboard box 15 and a right headboard box 16 are respectively installed at the left and right ends of the main machine bed 11, and the two rotating shafts 141 of the rotating device are respectively installed in the left headboard box 15 and the right headboard box 16. The left headboard box 15 can move left and right relative to the main machine bed 11.

[0047] Furthermore, the tensioning device includes a hydraulic cylinder 131 , one end of the hydraulic cylinder 131 is connected to a hydraulic station 132 , and an output end of the hydraulic cylinder 131 is fixedly connected to the left head box 15 .

[0048] In this embodiment, the output end of the hydraulic cylinder 131 moves left and right, thereby driving the left head box 15 to move left and right, and then driving the rotating shaft 141 installed on the left side of the main machine bed 11 to move left and right, so that the sucker rod 17 is tightened or relaxed.

After the carbon fiber coating is completed, the rotating device stops rotating, the sucker rod 17 is properly relaxed by the tensioning device, and then the chuck 12 releases the sucker rod 17 to remove the sucker rod 17 and enter the next processing step.

[0053] Furthermore, the rotating device includes a servo motor 142, which is mounted to the right side of a rotating shaft 141 at the right end of the main machine bed 11.
