[0041] A kind of preparation method of carbon fiber continuous sucker rod of the present invention is characterized in that comprising the following steps to make:

[0042] (a) A plurality of bundles of carbon fibers are drawn from the wire rack 1, wherein the carbon fiber reinforced layer A and the high modulus glass fiber layer B pass through the carbon fiber glue tank 3-1 under the traction of the traction device 11, and are soaked in the resin matrix glue solution. The resin matrix is Multi-functional epoxy resin system; pre-cured by heating in the small mold 4, and mold heating devices are distributed around the small mold, heating in two stages, and the heating temperature is 90-160°C;

[0043] (b) In the small mold, the carbon fiber reinforced layer A is covered with high-modulus glass fiber layer B and high-strength glass fiber, and the fiber braided wear-resistant layer C in the multi-bundle carbon fiber is drawn from the wire rack 1 through the braiding machine, Use ...

Embodiment 1

[0048] Example 1: First, 242 bundles of T300-12K fibers are drawn from the wire drawing frame 1, and after preheating treatment, they pass through the carbon fiber glue tank 3-1 under the traction of the traction device 11, and soak in the resin matrix glue liquid, and the resin matrix is ​​multifunctional. Epoxy resin system, the glue ratio is resin:curing agent=100:113;

[0049] The carbon fiber passes through the small mold 4 and is heated in two stages in the small mold. The temperature of the two zones is 90°C and 160°C for pre-curing;

[0050] 150 bundles of WS3000-2400tex glass fibers drawn from the wire drawing frame 1 pass through the inner hole of the braiding machine 5, and enter the outer layer glue tank together with the braided layer formed by 22 pieces of 1100dtex aramid fiber 1414, and soak the resin matrix glue solution. The resin matrix is Multifunctional epoxy resin system, the glue ratio is resin: curing agent: wear-resistant filler = 100:113:5; under the t...

Embodiment 2

[0053] Embodiment 2: according to embodiment 1, resin is replaced with four-functional epoxy resin, improves temperature resistance, the resin in the small glue tank 3-1: curing agent=100:126, the resin in the outer layer glue tank 3-2 : curing agent: wear-resistant filler = 100:126:5, the heating temperature of the dipping device is 40°C;

[0054] The die temperature is controlled at 110°C, and the pultrusion die with a hole diameter of 22mm is heated in 7 stages, the temperature is 130°C, 230°C, 250°C, the pultrusion speed is 0.27m / min, and the composite material rod is pultruded; The rod body of the composite material that is produced enters the post-curing heating furnace 10 for thermal stress treatment and post-curing. The post-curing heating furnace 10 is heated in three stages, and the temperature is 230°C, 195°C, and 120°C; the solidification becomes a three-layer structure with a diameter of 22mm Eccentric wear-resistant carbon fiber reinforced composite continuous su...

Abstract

The invention discloses a carbon fiber continuouspimping rod and a preparation device and method thereof. The carbon fiber continuouspimping rod comprises a carbon fiber reinforcement layer, a high modulus glass fiber layer and a fiber-weave abrasion-proof layer. The high modulus glass fiber layer is arranged on the outside portion of the carbon fiber reinforcement layer in a covering mode; and the fiber-weave abrasion-proof layer is arranged on the outside of the high modulus glass fiber layer in a woven and coiling mode. Continuous acrylonitrile-based carbon fibers with longitudinal stretching modulus of more than 230 GPa are adopted for the carbon fiber reinforcement layer; high modulus glass fibers with longitudinal stretching modulus of more than 90 GPa are adopted for the high modulus glass fiber layer; and the coiled fiber-weave abrasion-proof layer is made of abrasion-proof high modulus aramid1414 fibers. The problems of corrosion and partial abrasion during oil field oil extraction production are solved; the problem of influence on rod bodies by high temperature well washing is solved; the problem of oil extraction in a deep well and an extra-deep well is solved; and the pumping rod with corrosion-proof and partial-abrasion-resisting performance, and a small piston effectand convenient operation and use is manufactured.

Description

technical field [0001] The invention relates to oil industry sucker rods, in particular to a carbon fiber continuous sucker rod and its preparation device and method. 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 prepared by pultrusion process of glass fiber reinforced thermosetting resin, which has been widely used. Complex and easy to br...
