Abstract
Body of sucker rod is manufactured by using pull-squeeze molding technique through materials of phenol-formaldehyde resin as basis material, and carbon fiber and fiberglass as reinforcing material. Body of sucker rod is in oblate shape and flexible continuous type, providing properties of higher intensity, modulus, anticorrosion, antifatigue and heat stable higher than 150 deg.C. Advantages are easy of transportation and installation, saving energy, suitable to oil extraction in deep wells and ultra deep well.
Description
(1) technical field
The invention belongs to the production and the application of sucker rod in the oil exploitation sucker rod pump mechanical oil recovery, specially refer to the deep-well oil-extraction sucker rod.
(2) background technology
Domestic and international application mechanical oil recovery technology the most widely is the sucker-rod pumping technology, and sucker rod is one of its critical component.Sucker rod not only will bear multiple external force such as fluctuating load, oscillating load, shock loading in oil pumping process, and is subjected to the wearing and tearing of tempering property media such as the strong corrosion of the corrosive medium such as acid, alkali in the oil and grit.So require sucker rod to have high tensile, antifatigue, heatproof, performance such as wear-resisting, corrosion-resistant.Present domestic sucker rod is divided into two kinds of steel sucker rod and glass fiber reinforced plastic oil pumping rods by the material therefor difference, these two kinds of bars all are rigidity, the single bar limited length, to be connected with box cupling with a plurality of joints and could realize the down-hole oil pumping, in use have problems such as frictional resistance is big, serious wear, easy generation dropout.
External flexible continuous pumping rod mainly contains steel wire sucker rod, the cross section is oval-shaped steel band sucker rod and composite band sucker rod.Though preceding two kinds of bars have overcome some defectives of rigidity sucker rod, need to be equipped with workover rig, the welding tractor that cutting, heat treatment, welding and running and pulling device are housed, also need be equipped with the large scale trailer of storing continuous bar, it is very inconvenient that transportation is used.The composite band sucker rod adopts materials such as senior graphite, glass fiber, aramid fiber and vinylite to make, though the transportation installation is more convenient, cost height and non-refractory are not suitable for deep-well and ultradeep well oil extraction.
(3) summary of the invention
The invention reside in and develop composite continuous sucker rod and the manufacturing process thereof that is applicable to deep-well and ultradeep well oil exploitation, solve low, the deep mining problem of difficult of sucker rod pumping efficient for a long time.
High-temperature resistance carbon fiber composite continuous sucker rod of the present invention is flexible continous way sucker rod, and its reinforcing material is a carbon fiber, and matrix is a phenolic resins, adopts the pultrude process moulding.
Carbon fibre pumping rod form of structure of the present invention is oblate shape, and is continuously flexible, can coil to produce and transportation, made by carbon fiber enhancement resin base composite material.Wherein reinforcing material is continuous carbon fibre and glass fiber, and matrix material is the phenolic resins glue, and wherein the percentage by weight of phenolic resins is 70-85%, and the percentage by weight of curing compound six methines four acid anhydrides is 15-30%.The percentage by weight of carbon fibre pumping rod raw material proportioning of the present invention is:
Carbon fiber 60～75%
Glass fiber 0.5～10%
Phenolic resins 30～40%
High-temperature resistance carbon fiber composite continuous sucker rod adopts the pultrude process moulding.Be about to multi-beam carbon-fiber and glass fiber behind phenolic resins glue dipping, top layer compound glass silk ribbon enters the pultrusion mould, at the rapid gel solidification in the preheating zone and forming and hardening district of pultrusion mould, again through after curing oven promote the phenolic aldehyde curing cross-linked after traction is wound on the disk.Pultrusion die Fen San district temperature control, first district's temperature is 120～150 ℃, and second district's temperature is 160～180 ℃, and the 3rd district's temperature is 180～210 ℃; Pultrusion speed is 0.15～0.65 meter/minute, behind the pultrusion, carries out the back and solidifies, and back solidification temperature is 160～210 ℃.
The technical indicator of carbon fibre composite coiled rod of the present invention is:
Hot strength 〉=1800MPa
Stretch modulus 〉=120GPa
Anti-fatigue performance inefficacy cycle-index 〉=10

High-temperature resistance carbon fiber composite continuous sucker rod has higher intensity and modulus, and is corrosion-resistant, and antifatigue, long service life, its performance obviously are better than glass fiber reinforced plastic oil pumping rod and other resin matrix composite material sucker rod; Compare with the steel sucker rod, in light weight, flexible good, and the cross section is less, and is little with the frictional force of oil pipe, can reduce power consumption greatly, the line density of sucker rod of the present invention is very little, be equivalent to 0.05 times of conventional steel shank, can reduce the polished rod load of sucker rod greatly, be suitable for deep-well and ultradeep well and recover the oil.Adopt carbon fibre composite coiled rod of the present invention, convenient transportation, installation rate is fast, and the time and labour saving is safe and reliable.
(4) description of drawings
The sectional drawing of carbon fibre composite coiled rod of the present invention is made of carbon fiber enhancing phenolic resin as matrix resin 1 and glass fiber top layer 2 as shown in Figure 1.
The manufacturing process of carbon fibre composite coiled rod of the present invention as shown in Figure 2, mainly by putting guide frame 3, steeping vat 5, pultrusion die 7, tractor 8, back curing oven 9, closed reel 10 is formed.To count the bundle carbon fiber earlier is placed in and puts on the guide frame 3, carbon fibre tow 4 enters pultrusion die 6 after steeping vat 5 evenly soaks the Ji resin adhesive liquid, by forming oblate sucker rod 7 behind the pultrusion, by tractor 8 tractions, through after behind the curing oven 9 further crosslinking curings, be coiled on the closed reel 10.
(5) specific embodiment
With the carbon fiber is fortifying fibre, and the glass fiber silk ribbon is a sealer, is matrix with phenolic resins, and the specific embodiment of production sucker rod of the present invention is as follows:
200 bundle 12K carbon fibers are walked around and are put guide frame, enter the glue storage tank impregnation that contains phenolic resins, the percentage by weight of phenolic resins is 75% in the phenolic resins glue, the percentage by weight of curing compound six methines four acid anhydrides is 25%, be that the continuous glass fabric of 40mm is compound with fabric width then, enter preforming tool through the resin controller.The effect of resin controller is to guarantee that resin fully soaks into fiber, and the effect of preforming tool is to make the fiber after the infiltration make blank through preheating, and makes the fiber that soaked glue enter main moulding form exactly.
The blank that comes out from preforming tool enters main moulding form.Long 1.3 meters of main moulding form, the die cavity cross section is 32 * 4mm, makes with the instrument steel, and handles through chromium plating or nitriding.So not only help the demoulding but also can reduce frictional resistance, prolonged the application life of mould.In the main moulding form, adopt electrical heating that temperature is divided into three districts (130 ℃, 170 ℃, 200 ℃).After the curing, clamp goods by the first special chuck and deliver second chuck, in this process, finish demoulding cooling, after second chuck is clamped goods, first chuck removes to clamp the goods that come out from main moulding form again, second chuck with goods through traction send to length be 4 meters after curing oven, 200 ℃ of back curing oven temperature, then by have diameter be the up-coiler rolling of 1.5 meters disks on disk, promptly finish the manufacturing process of carbon fibre composite coiled rod body.
