Description

Technical Field

[0001] The utility model relates to the technical field of oil drilling and production, in particular to a wrench square die forging device for a carbon fiber reinforced metal sucker rod. Background Art

[0002] The sucker rod is a slender rod of the pumping well. It is connected to the bare rod at the top and the oil pump at the bottom, and plays the role of transmitting power. The wear resistance and corrosion resistance of the sucker rod determine and affect the operation cycle of the entire oil pumping equipment. The material of the sucker rod is generally medium-low carbon alloy steel that has been quenched and tempered. It is connected one by one with a coupling in the oil pipe and extends to the piston rod of the downhole oil pump to pump oil through reciprocating motion.

[0003] Most of my country's oil fields have entered the middle and late stages of development, with increasingly high water content. Water injection and other production-increasing measures are often used, and the oil field reinjection water is basically sewage directly reinjected, resulting in a very harsh working environment for the pumping rod. Highly mineralized well fluid contains 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. - , CO2 and H2S corrosion has always been a world problem in oil production engineering. Moreover, the friction between the sucker rod and the inner wall of the oil pipe will generate heat energy, which will activate its surface. Under the action of corrosive production fluid, the corrosion rate of the sucker rod surface will be greatly accelerated. In addition, the influence of sand content, the influence of wax and scaling in the oil well, and the influence of the viscosity of the production fluid will also promote corrosion and eccentric wear on the sucker rod surface.

[0004] The long-term asymmetric alternating load and the combined effects of oil, gas, water and corrosive media make the sucker rod a very low reliability device in mechanical oil production. How to effectively control the corrosion and eccentric wear of the sucker rod has become an urgent task to achieve efficient and stable production in the middle and late stages of oil field development. According to statistics, surface failure of the sucker rod accounts for more than 90% of the failure of the sucker rod, and surface failure will also bring the hidden danger of fracture failure, which brings great inconvenience to 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 mining environment, the coating is prone to peeling, falling off, and wearing, forming an anti-corrosion and wear shortcoming. 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 anti-corrosion and wear resistance. However, after the rod body is spray-welded with the anti-corrosion alloy coating, secondary solid solution strengthening is required. 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 eccentric wear technology of sucker rods. Ultimately, the carbon fiber coating technology was used to effectively improve the overall corrosion resistance and anti-eccentric wear performance of the sucker rods, with a high cost-effectiveness.

[0008] Carbon fiber refers to high-strength and high-modulus fiber with a carbon content of more than 90%. It is the highest in high temperature resistance among all chemical fibers. It is made of acrylic and viscose fibers and is carbonized by high temperature cracking. It is a high-end material for manufacturing aerospace and other industries. Carbon fiber is a new generation of reinforcing fiber, known as the "king of new materials" and "black gold". Carbon fiber has excellent mechanical properties and chemical stability. Its specific gravity is less than 1 / 4 of that of steel, and its strength is 6 to 10 times that of steel. It has the characteristics of low density, corrosion resistance, high temperature resistance, friction resistance, fatigue resistance, low thermal and moisture expansion coefficient, and excellent durability.

[0009] When the sucker rod is used in the oil well for a long time, a lot of oil and rust will adhere to its outer surface, which will not only corrode the sucker rod body, but also increase the friction between the sucker rod and the sealing box. When pulling out from the well, the oil adhered to the outer surface of the conventional sucker rod is easy to drip on the well site, which not only wastes crude oil, but also pollutes the environment, and also affects the operation efficiency and strength. The sucker rod coated with carbon fiber has excellent corrosion resistance and strong anti-adhesion, and has the characteristics of low friction coefficient and self-lubrication. It can effectively reduce the adhesion of oil and rust on the rod column surface, and can also effectively slow down the occurrence of waxing on the rod column surface, and can effectively reduce the occurrence of bare rod breakage accidents in corrosive environments, with high cost performance.

[0010] In the process of carbon fiber coating of sucker rod, firstly, the carbon fiber needs to be stretched and tensioned, soaked in liquid resin, squeezed and wound on the sucker rod after the resin is squeezed. When winding, the two ends of the sucker rod need to be clamped, tensioned and rotated, and then the carbon fiber winding device is moved back and forth to coat the carbon fiber on the sucker rod. After winding, it is also necessary to heat treat it to fully combine the resin, carbon fiber and metal sucker rod. After the heat treatment, it is necessary to set a stainless steel clamp sleeve on the shoulder, wrench square, flange, transition zone and part of the rod body of the sucker rod, and the stainless steel clamp sleeve and the sucker rod are forged at one time to achieve complete extrusion sealing between the carbon fiber layer coated on the outside of the sucker rod and the polymer plastic ring and the stainless steel clamp sleeve, thereby further enhancing the corrosion resistance of the carbon fiber wrapped sucker rod. At present, there is no automated device for forging the stainless steel clamp sleeve and the sucker rod on the market.

[0011] In view of this, the utility model provides a wrench square die forging device for a carbon fiber reinforced metal sucker rod, which realizes complete extrusion sealing between the carbon fiber layer coated on the outside of the metal sucker rod and the polymer plastic ring and the clamp sleeve, and enhances the corrosion resistance of the carbon fiber wrapped metal 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.
