Abstract
The invention relates to a novel carbon fiber sucker rod and a manufacturing method thereof. The sucker rod in the invention consists of a rod body and rod joints, wherein the rod body is prepared from carbon fiber composite, the both ends of the rod body are connected with the rod joints; the rod joints are prepared from carbon fiber composite; and the rod joints are machined on the rod body directly and integrated with the rod body. The sucker rod is prepared from the main raw materials comprising T300 carbon fiber-12K, epoxy resin, Me-THPA, accelerator and release agent through the pultrusion technology. According to the invention, as the sucker rod is corrosion-resistant, is difficult to break and has light weight, the time of downhole operations in a pumped well is reduced, the maintenance-free period is prolonged, and the downhole operation cost and the material cost for changing the sucker rod are saved. By adopting the carbon fiber composite sucker rod disclosed by the invention, the transportation is convenient, the installation speed is high, the time and the labor are saved and the operation is safe and reliable.
Description
Technical field
The present invention relates to the oil production equipment and the manufacturing process of petroleum industry, particularly a kind of pumping rod of composite carbon fiber material and manufacture method thereof, the pumping rod of composite carbon fiber material of being processed is suitable for using on various well on the beams.
Background technology
Sucker rod is one of sucker rod pumping key part, in the sucker rod pump working process, calculates according to 6-7 time/minute jig frequency, and sucker rod pumps up to about about 9300 times every day.In this to-and-fro movement process, sucker rod is subjected to the influence of various factors, mainly contains the reactive force from various interaction mediums.Various corrosive mediums in the output liquid comprise dirt of separating out in the wax of separating out in dissolved oxygen, carbonic acid gas, hydrogen sulfide, dissolved salts, sand, the crude oil in crude oil, water and the water, the water etc., and sucker rod lost efficacy because of attrition and attack as a result.In addition, repeated stress failure originally also can take place in sucker rod when bearing repeated load for a long time.Final result causes workover treatment, and workover treatment has also been lost crude production rate except that introducing the well workover expense.
Along with each oilfield exploitation of China goes on the philtrum later stage mutually, the oil production technology that little pump is taken out deeply, big pump is adopted is by force applied, simultaneously owing to mineralizer content height in the well liquid has the obvious corrosion effect to pumping rod made by steel.Therefore, present D grade pumping rod and super-strength sucker rod do not have Corrosion Protection, and glass fiber reinforced plastic oil pumping rod is low because of its fatigue strength, easy fracture etc. can not satisfy have corrodibility well liquid, little pump is taken out deeply, the needs of the oil production technology that big pump is adopted by force, and often carry out borehole operation, cost for oil production height.The on-the-spot at present sucker rod that uses all connects with box cupling.The box cupling diameter is big than sucker rod and knock-off joint diameter, and the box cupling effect that is produced strengthens oil-pumping resistance, and the oil well pump coefficient of unfullness increases.
Summary of the invention
The present invention is in order to overcome above-mentioned deficiency, purpose purport of the present invention provides a kind of novel carbon fiber sucker rod and manufacture method thereof, provide a kind of corrosion-resistant, intensity is high, not easy fracture, light weight, and solve carbon-fiber continuous rod and use face narrow, the sucker rod of shortcomings such as operation inconvenience, make it not use box cupling to connect, eliminate the box cupling effect, improve the fill factor of oil well pump, prolong being excused from a college course the phase of rod-pumped well, reduce the number of times of remedial operation, reduce cost for oil production.
Sucker rod among the present invention is made up of the body of rod and knock-off joint, and the body of rod adopts carbon-fibre composite to make, and two ends union lever joint, knock-off joint use carbon-fibre composite to make, and directly processing becomes one with the body of rod on the body of rod.
Technical scheme of the present invention is: main starting material have T300 carbon fiber-12K, Resins, epoxy, first hydrogen four basic phthalic anhydrides, promotor, remover, adopt the pultrude process moulding.Its technical process is as follows:
A, row's yarn are placed on carbon fiber wire on the creel, put silk then.
B, impregnation fully immerse by creel, wherein 100 parts of Resins, epoxy, first hydrogen four 80 parts of basic phthalic anhydrides, 2 parts of promotor, remover 2-6 part;
C, preheating, preheating temperature are 50
+10 ℃
D, curing molding, curing molding Fen San district's temperature control, first district's temperature is 135
+10 ℃, second district's temperature is 170
+5 ℃, the 3rd district's temperature is 200
+10 ℃;
E, after fixing, the temperature in after fixing district are 210
+10 ℃;
F, traction are drawn to curing area by tractor;
G, coiling; Be wound on the disk through traction.
After using the present invention, because sucker rod is corrosion-resistant, easy fracture, in light weight not, the borehole operation number of times of rod-pumped well reduces, and has prolonged the phase of being excused from a college course, and has saved the borehole operation expense and has changed the Master Cost of sucker rod.Adopt pumping rod of composite carbon fiber material of the present invention, convenient transportation, fast, the time and labour saving of installation rate, safe and reliable.
