Abstract
The utility model discloses a wear preventing centralizer for a sucker rod. The centralizer comprises two metal half pipes which can be buckled on a sucker rod, wherein the external surfaces of the two half pipes are respectively fixedly provided with corresponding centralizing bodies which are made of wear resisting materials, oil flow passages for the passing of crude oil are arranged on the two centralizing bodies and a fixing and fastening device is arranged between the two half pipes. The wear preventing centralizer for the sucker rod has the advantages of simple structure and convenient installation, and the utility model can be widely used for an oil pumping machine sucker-rod pump oil production equipment.
Description
Technical field
The utility model relates to a kind of oil exploration equipment, specially refers to the sucker rod abrasionproof centralizer in a kind of sucker rod pump extraction oil oil well rig.
Background technology
In present oil exploitation both domestic and external, one of crude oil extraction method is the oil pumper sucker rod pumping that ground installation drives, and is current domestic and international application oil production method the most widely.Because equipment is simple, small investment, convenient management, applicability is strong, proper uses widely, has the bar oil extraction pump to recover the oil at present and accounts for about 90% of the total well number that recovers the oil.The quality that this shows bar oil extraction pump performance has very important effect in oil exploitation.And in use exist very big problem as the sucker rod and the oil pick-up tube of sucker rod pumping critical component: when sucker rod moved in inclined shaft, sucker rod can contact with the inwall of oil pipe, produced the friction that continues, and caused oil pick-up tube wearing and tearing, cracking.This reduces the life-span of oil pick-up tube greatly, shortens oil well repair free period, and oil pick-up tube wearing and tearing, CRACKING ACCIDENT take place frequently, and needs continually closing well, rountrip continually, changes oil pick-up tube, has increased cost of winning.
Summary of the invention
The technical problems to be solved in the utility model has provided and a kind ofly can fully reduce wearing and tearing between oil pick-up tube and the sucker rod to prolong the oil pick-up tube sucker rod abrasionproof centralizer in application life.
For solving the problems of the technologies described above, the technical solution of the utility model is: sucker rod abrasionproof centralizer, described centralizer comprises two metal semicanals that can snap onto on the sucker rod, be installed with the centralizer body of making by high-abrasive material accordingly on the external surface of described two semicanals respectively, described two centralizer bodies are provided with the oil flow channel that passes through for crude oil, are provided with device for fastening between described two semicanals.
As a kind of optimal way, described device for fastening is the bolt clamp device that is arranged between two semicanals.
As another kind of optimal way, described centralizer body is high-intensity rubber centralizer body.
Adopt said structure sucker rod abrasionproof centralizer,, not only solved the wearing and tearing between oil pick-up tube and the sucker rod, and prolonged the application life of oil pick-up tube owing to be on the external surface of sucker rod, to be fixed with the abrasionproof centralizer.And adopt the mode of two semi-canal types and fix by fastening bolt, not only make centralizer convenient on making, and can carry out installation or removal according to actual conditions so that centralizer and sucker rod can be stored respectively and transport, also convenient in the use.Adopt high-intensity elastomeric material to make wear-resisting centralizer body on the centralizer, both strengthened the abrasion resistance of centralizer, also reduced the cost of manufacture of centralizer.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described:
Accompanying drawing is the structural representation of sucker rod abrasionproof centralizer of the present utility model.
The specific embodiment
With reference to accompanying drawing, a kind of sucker rod abrasionproof centralizer of the present utility model is: comprise two metal semicanals 2 that can snap onto on the sucker rod 1, on the external surface of two semicanals 2, be installed with the centralizer body of making by high-abrasive material accordingly 3 respectively, be to strengthen the abrasion resistance of centralizer and reduced the cost of manufacture of centralizer, centralizer body 3 can adopt to have that high-intensity elastomeric material is made and is cured as one with the external surface of two semicanals 2; For making things convenient for the smooth of crude oil in the oil pipe to flow, on two centralizer bodies 3, be provided with the oil flow channel 5 that passes through for crude oil; Between two semicanals 2, be provided with device for fastening 4, this device for fastening 4 can be the bolt clamp device that is arranged between two semicanals 2, this device for fastening 4 can be at the two ends of a semicanal and is provided with open-work, another semicanal is provided with corresponding silk hole, the silk hole that fastening bolt passes open-work and another semicanal on the semicanal cooperates fastening, certainly, the mode that also can adopt screw bolt and nut to cooperate realizes, and for strengthening the fixed performance between this two semicanal 2 and the sucker rod 1, the internal diameter of this two semicanal 2 should be corresponding with the external diameter of sucker rod 1, and can double wedge be set at the inner surface of two semicanals 2, can certainly corresponding double wedge also be set at the external surface of sucker rod 1, cooperate the fastening performance that strengthens between two semicanals 2 and the sucker rod 1 with it by the double wedge of two semicanals, 2 inner surfaces.
Sucker rod abrasionproof centralizer structure of the present utility model is simple, easy for installation, and effect is remarkable, can be applicable to widely in the middle of the oil pumper sucker rod pumping equipment.
