Chinese patent CN1417449 discloses a method for preparing an anti-friction sucker rod. The method is to secondary injection mold an anti-friction block made of nylon and other materials on the formed sucker rod body to reduce the use of cladding materials and reduce the continuous wrapping. Covering the cost and complexity of the process, but the size of the injection-molded anti-wear block is relatively small, and it is relatively independently distributed on the rod body. Often, the anti-wear block is separated from the rod body, and the phenomenon of "candied haws" appears
However, the sucker rod adopts a one-time overall processing method of pultrusion and coating (including wire feeding-resin dipping-coating layer coating-preforming-curing-coiling process), and the coating layer is fiber fabric reinforced thermosetting resin. Not only increases the material cost, but also the partial wear resistance of the fiber fabric coating is not ideal
In addition, since the cross section of the carbon fiber

preparation example Construction

[0036] A method for preparing a fiber-reinforced composite material anti-eccentric wear continuous sucker rod mentioned in the present invention comprises the following steps:

[0037] (a) Draw out multiple bundles of carbon fibers from the creel (1), and pass through the carbon fiber resin impregnation equipment (3-1) under the traction of the traction device (11), and infiltrate the resin matrix glue solution, and the resin matrix is ​​a multifunctional epoxy resin system;

[0038] (b) In addition to the carbon fiber in the inner layer, use a winding machine (4) to wind two layers of high-modulus glass fiber winding layers with a thickness of 0.3-1.5 mm in forward and reverse directions and a cross angle of 50°-80°; after preforming (5 ) in the inner hole (5a); the wear-resistant high-modulus glass fiber drawn from the creel (1) passes through the glass fiber resin infiltration equipment (3-2), and enters the outer layer of the preform (5) Yarn holes (5b), evenly covering th...

example 1

[0045] Example 1: First, 190 bundles of T300-12K fibers are drawn from the creel (1), preheated, and then passed through the carbon fiber resin impregnation equipment (3-1) under the traction of the traction device (11) to infiltrate the resin matrix glue, The resin matrix is ​​a multifunctional epoxy resin system, and the glue solution ratio is resin:curing agent=100:100;

[0046] In addition to the inner layer of carbon fiber, use a winding machine (4) to wind two layers forward and reverse (facing the direction of movement of the carbon fiber bundle, the first layer is wound clockwise, and the second layer is wound counterclockwise), each layer uses 10 bundles of EPX17 -1200tex glass fiber, the thickness of the winding layer is 0.4mm, the winding angle is 55°, the winding layer has no gaps and no superposition;

[0047] The wound carbon fiber layer and the winding layer pass through the inner hole (5a) in the preform (5) to form a corrugated shape of 10 corrugations;

example 2

[0052] According to Example 1, after the post-curing is completed, the rod body of composite material enters the extrusion equipment (12) through the traction device (11), and is continuously coated with a modified ultra-high molecular weight polyethylene wear-resistant layer with a thickness of 2mm, which can be used for a long time The temperature is 90°C, forming a four-layer structure of partial wear-resistant carbon fiber reinforced composite continuous sucker rod;

[0053] It is wound on a disc with a diameter of 3.5m by a winding device (13).

Abstract

The invention relates to an eccentric-wear-resistant carbon fiber reinforced composite material continuous sucker rod and a manufacturing device and method thereof.The continuous sucker rod is mainly composed of a carbon fiber reinforced layer along the axial direction of a rod body, a high-modulus glass fiber winding layer, and a wear-resistant high-modulus glass fiber reinforced layer along the axial direction of the rod body, the carbon fiber reinforced layer on the inner layer and along the axial direction of the rod body is formed by continuous acrylonitrile-based carbon fibers, the high-modulus glass fiber winding layer is a high-modulus glass fiber winding layer, the wear-resistant high-modulus glass fiber reinforced layer along the axial direction of the rod body is formed by wear-resistant high-modulus glass fibers, and a resin matrix is a multifunctional group epoxy resin system.The continuous sucker rod has the advantages that the winding layer is added, the inside of the continuous sucker rod is of a wavy structure, and three structural layers are solidified and formed in one time, so that contact area between carbon fibers and glass fibers is increased, interlayer bonding force is increased, layering among different reinforced materials when the rod body twists due to a concentric circle structure is avoided, radial and axial compressive strength is improved, and bending diameter is reduced.

Description

technical field [0001] The invention relates to a petroleum industry oil recovery equipment, a preparation method and a device, in particular to a continuous sucker rod made of eccentric wear-resistant carbon fiber reinforced composite material, and a preparation device and method thereof. Background technique [0002] Due to the increasingly complex types of developed reservoirs, the continuous increase of well depth and the continuous deterioration of the well and mine environment, the problems of corrosion and eccentric wear have become problems that need to be solved urgently in the oil production process of oilfields. Because of its light weight, high strength and corrosion resistance, composite sucker rods have gradually replaced traditional metal sucker rods. The composite material sucker rods currently used mainly include two categories: glass fiber reinforced plastic sucker rods and carbon fiber reinforced composite continuous sucker rods. FRP sucker rods are prepa...
