Abstract
A high performance wearable centralizer for preventing abrasion and centralizing in the oil field sucker-rod pumping driven well oil production process comprises an upper connector, a high performance wearable centralizing body and a center pole. The high performance wearable material PEEK is injected into a mould to form the high performance wearable centralizing body at a high temperature; and the center pole is sleeved inside the high performance wearable centralizing body which is in threaded connection with the upper connector. The high performance wearable centralizer solves the problems of the prior art that the metal material is easy to produce metal powder, the service life of a sucker-rod pump is affected, and the wearing resistance and the high-temperature resistance of the polymer material are not balanced. The high performance wearable centralizer can be widely used in the anti-abrasion and centralizing processes in the oil field sucker-rod pumping driven well oil production process.
Description
Technical field:
The utility model relates to the high-performance abrasion-proof centralizer that abrasionproof in a kind of oil field sucker rod pumping motor-pumped well oil recovery manufacturing process is set upright usefulness.
Background technology:
Present domestic oil field sucker rod pumping motor-pumped well abrasionproof set upright generally all be adopt wear-resistant, macromolecular material carry out wear-resistantly setting upright, because the sucker rod pumping motor-pumped well is produced throughout the year, the metal sucker rod easily produces wearing and tearing and forms metal powder and influence the application life of oil well pump and damage oil pipe.Technical measures such as roller, steel ball, copper alloy and the high rigidity that metal material makes, wear-resisting box cupling are often adopted in the oil field for this reason, also have in the recent period and adopt macromolecular material to make centralizer body, macromolecular material comprises nylon, fill technical measures abrasionproofs such as tetrafluoroethene sets upright.The problem that abovementioned technology exists is that metal material easily produces metal powder, influences the rod pumping pump life-span, and polymer-material wear-resistant, high temperature resistant can not taking into account simultaneously are promptly wear-resisting high temperature resistant again.
The utility model content:
The utility model purpose is to provide a kind of high-performance abrasion-proof centralizer, and it has solved the metal material that exists in the prior art and has easily produced metal powder, influences the sucker rod pumping machine life-span, the problem that polymer-material wear-resistant is high temperature resistant can not be taken into account simultaneously.
The technical scheme that its technical problem that solves the utility model adopts is: the high-performance abrasion-proof centralizer by top connection, high-performance abrasion-proof centralizer body, center-pole, form; With high performance high-abrasive material polyether-ether-ketone is PEEK, at high temperature injects mould molding and makes the high-performance abrasion-proof centralizer body, and center-pole is inserted in the high-performance abrasion-proof centralizer body, and the high-performance abrasion-proof centralizer body is threaded with top connection.
The new beneficial effect of this practicality is, and is simple in structure, easy to install and use, have high temperature resistant, wear-resisting, shock resistance, use this wear-resisting centralizer obviously to improve sucker rod pumping machine application life, save sucker rod pumping machine oil recovery cost of production, have high economic benefit.
Description of drawings:
Accompanying drawing is the utility model overall structure schematic diagram.
Among the figure, 1, top connection, 2, the high-performance abrasion-proof centralizer body, 3, center-pole.
The specific embodiment:
In the accompanying drawings, the high-performance abrasion-proof centralizer is made up of top connection 1, high-performance abrasion-proof centralizer body 2, center-pole 3; High performance high-abrasive material PEEK (polyether-ether-ketone) is at high temperature injected mould molding make high-performance abrasion-proof centralizer body 2, center-pole 3 is inserted in the high-performance abrasion-proof centralizer body 2, high-performance abrasion-proof centralizer body 2 is threaded with top connection 1.
