Abstract
The utility model discloses a wearing resisting protector for an oil pumping pipe, which comprises a pipe-shaped body which can be fixedly connected with a coupling clamp of an oil pumping pipe, wherein both ends of the external surface of the body are respectively provided with external threads, and the internal wall of the body is provided with a non-metal wear resisting protective layer. The wear resisting protector for the oil pumping pipe of the utility model adopts simple structure and realizes the wear problem of the oil pumping pipe and the coupling clamp of the oil pumping pipe in oil production industry, the efficiency of oil production equipment is improved and the production cost of petroleum is reduced.
Description
Technical field
The utility model relates to a kind of oil exploration equipment, specially refers to the oil pick-up tube wear-resistant protection device 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, as as shown in the accompanying drawing 2, adjacent two oil pick-up tube are fixed on the two ends of an oil pick-up tube box cupling, adjacent two sucker rods then connect by rod collar and place oil pick-up tube to carry out oil extraction operation, when sucker rod moves in inclined shaft, sucker rod can contact with the inwall of oil pipe with rod collar, produces the friction that continues, and causes 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 just 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 a kind of oil pick-up tube wear-resistant protection device that can effectively reduce sucker rod and rod collar to the oil pick-up tube wearing and tearing.
For solving the problems of the technologies described above; the technical solution of the utility model is: oil pick-up tube wear-resistant protection device; comprise the tubular body that can fixedly connected with the oil pick-up tube box cupling, the two ends of described external surface are respectively equipped with external screw thread, and the inwall of described body is provided with by nonmetal wear-resistant protective layer.
As a kind of optimal way, the two ends of described nonmetal wear-resistant protective layer are provided with chamfering.
Adopt the oil pick-up tube wear-resistant protection device of said structure; because this oil pick-up tube wear-resistant protection device is arranged on oil pick-up tube box cupling place; therefore; it can directly constitute the part of whole oil pumping piping with oil pick-up tube and oil pick-up tube box cupling; the two ends that promptly are equivalent to every oil pick-up tube in whole oil pumping piping are respectively equipped with and establish nonmetal wear-resistant protective layer tube wall in one; make sucker rod and rod collar when oil pick-up tube is carried out contact wear; at first contact with nonmetal wear-resistant protective layer; thereby reach when avoiding sucker rod and rod collar in oil pick-up tube, to move wear problem to oil pick-up tube; and with respect to protector being set at sucker rod and rod collar; it does not increase the weight of sucker rod, the corresponding load that does not yet increase surface driving equipment.Two ends at the nonmetal wear-resistant protective layer of oil pick-up tube wear-resistant protection device are provided with chamfering, and suffered obstruction was reduced to maximum limit when sucker rod and rod collar were moved at the protector place.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described:
Scheme of installation when Fig. 1 is the operate as normal of oil pick-up tube wear-resistant protection device of the present utility model;
Fig. 2 is the scheme of installation when sucker rod and oil pick-up tube operate as normal in the prior art.
The specific embodiment
With reference to accompanying drawing 2, oil pick-up tube in the equipment of existing oil pumper sucker rod pumping, the oil pick-up tube box cupling, sucker rod and the rod collar scheme of installation when operate as normal, two oil pick-up tube 5 are fixed on the two ends of an oil pick-up tube box cupling 1, sucker rod 4 connects by rod collar 3 and places oil pick-up tube 5 to carry out oil extraction operation, under this kind situation, when sucker rod 4 in inclined shaft particularly in some bending sections, because the stretching of oil pick-up tube 5, swing and sucker rod 4 move up and down or tremble, the sucker rod 4 particularly external diameter oil pick-up tube box cupling 3 that is coarser than sucker rod 4 can contact with the inwall of oil pick-up tube 5, produce powerful frictional force, cause the wearing and tearing of oil pick-up tube 5 tube walls and break.
With reference to accompanying drawing 1; a kind of oil pick-up tube wear-resistant protection device of the present utility model is: comprise the tubular body 2 that can fixedly connected with oil pick-up tube box cupling 1; two ends at body 2 external surfaces are respectively equipped with external screw thread; these body 2 two ends can be docked with the oil pick-up tube box cupling respectively at external screw thread; inwall at body 2 is provided with by nonmetal wear-resistant protective layer 21; this nonmetal wear-resistant protective layer 21 can adopt by macromolecular material, and like rubber etc. are made, and also can adopt picture to contain nonmetals such as graphite, silicon and make.In order to realize the abrasionproof between 4 pairs of oil pick-up tube 5 of sucker rod and the oil pick-up tube box cupling 1; as shown in Figure 1; the internal diameter of this body 2 can be arranged to less than the internal diameter of oil pick-up tube box cupling 1 and will allow sucker rod 4 and rod collar 3 passes freely through in oil pick-up tube box cupling 1 and oil pick-up tube 5 tube chambers; simultaneously, also can be provided with chamfering 22 at the two ends of nonmetal wear-resistant protective layer 21.
The normal oil recovery when producing; can fixedly connected with oil pick-up tube box cupling 1 respectively by the external screw thread at body 2 two ends; and the free end of oil pick-up tube box cupling 1 is connected with oil pick-up tube 5 respectively; connect successively; constitute the oil recovery piping of whole oil well; then; sucker rod 4 connected successively by rod collar 3 place with among the mounted oil pipe; the production of can recovering the oil normally; when sucker rod 4 in inclined shaft particularly in some bending sections; because a variety of causes; oil pick-up tube 5 can produce and stretch; swing and sucker rod 4 move up and down or tremble; this moment, sucker rod 4 can at first contact with the nonmetal wear-resistant protective layer 21 of body 2 inwalls with rod collar 3; and, have certain soft elasticity because nonmetal wear-resistant protective layer 21 is to be made by nonmetals, therefore just stopped sucker rod 4; the direct wearing and tearing of rod collar 3 and oil pick-up tube 5; thereby protected sucker rod 4; rod collar 3 and oil pick-up tube 5 have prolonged their application life.
Oil pick-up tube wear-resistant protection device of the present utility model has adopted simple structure to realize wearing and tearing, the splintering problem of the oil pumping tube wall in the oil recovery industry, has improved the efficient of oil production equipment greatly, has reduced the cost of winning of oil.
