Abstract
The completely protected oil pump consists of pump tube, outer tube, protector, oil pump, oil pumping rod centralizer. The protector has protecting cap to isolate the upper well fluid and prevent silt, rust, scale and other impurity from entering to the oil pump tube, while the silt and other impurity are deposited and stored between the pump tube and the outer tube. The oil pumping rod centralizer protect the pump tube comprehensively against bending and other deformation. The present invention can raise the oil pump pass percent in well repair and prolong the use period by 2-3 times.
Description
Technical field: the present invention has announced a kind of oil well pump that is used for the sucker rod pumping of petroleum production.
Background technique: at present, the tubing pump of the oil well pump of in the rod pump petroleum production, using, major part is the whole tube of a liner-less pump, aborning because pumping hole is the open ports formula, when rod collar and piston are gone into the well when the oil well well workover, can wipe the rust deposite on the tube inner wall off, it is fallen in the pump, during stopping production on the pump in the oil pipe silt particle, rust deposite and impurity also easily fall in the pump and be deposited on the pumping hole, oil well pump will wear and tear when driving a well, the lighter makes the pump leakage, and stifled holddown of weight person and trip, standing valve have a strong impact on pumping well well workover quality and oil well pump service life.And because the part oil well pump is longer, do not note in the transportation process making the pump barrel bending, the underground bushing distortion also can make the pump barrel bending, dress packet under the pump, and the seat envelope load of packet also easily makes the pump barrel bending, makes the oil well pump can not ordinary production.
Summary of the invention: the objective of the invention is to design a kind of full protection sand setting anti-sticking oil well pump.
The present invention is that following mode realizes, in connecting a steel, the upper end of oil well pump manages, pipe upper end dress has the flexible anti helmet of slot in the steel, prevent that sediment contamination is deposited in the pump, the outside of oil well pump pump barrel is adorned a steel urceolus and is connected with the oil well pump lower end, can sink silt particle between pump barrel and the steel urceolus, adorns centralizer between oil well pump pump barrel and the urceolus, adorn a block on the first sucker rod body in oil well pump piston upper end, first sucker rod top dress oil pumping rod centering device.
The function that the present invention realizes: 1. sediment contamination is deposited on wearing and tearing oil well pump in the pump when preventing to stop well, can improve oil well pump life cycle 2-3 doubly.2. rust deposite impurity sinks in the pump when preventing well workover, improves the well workover up-to-standard rate.3. prevent to place in the transportation bending of colliding with of improper oil well pump, cause oil well pump work undesired.4. simple with conventional sand-proof oil-well pump structure compared, cost is low, construction is identical with conventional oil well pump.
5. prevent that the crooked oil well pump of packer set load or hole diameter is crooked after going into the well, and influences oil well pump work.
Below in conjunction with diagrammatic sketch the present invention is further described:
Figure one is a structural representation of the present invention:
Accompanying drawing and explanation: form by pipe (6) pump barrel (7) urceolus (8) pump centralizer (9) piston (10) seal ring (11) standing valve (12) lower contact (13) in sucker rod (1) oil pumping rod centering device (2) block (3) upper connection (4) protective hat (5).
An embodiment of this invention: sucker rod (1) is with used identical, at sucker rod upper end dress oil pumping rod centering device (2), oil pumping rod centering device is with used identical, oil pumping rod centering device can prevent sucker rod partial wear protective hat (5), dress block (3) on the sucker rod body, block is an annulus umbrella flexible body, can make of flexible material, effect is to cover on protective hat (5), covers the protective hat slit.The sucker rod lower end is connected with piston.Pump barrel (7) is the steel cylinder of an inner wall smooth, cooperates oil pumping with the piston clearance, and piston (10) is the annulus steel cylinder, place in the pump barrel.The outer rib-loop of pump barrel lower end system, the outer rib-loop of pipe (6) lower end in rib-loop connects in the system of upper end, interior pipe is the outer rib-loop steel pipe of lower end system, fixed protection cap (5) behind the undergauge of upper end, and protective hat is the annulus cap-shaped body, useful flexible material is made, its limit portion is thick more and more thinner to the top, and this structure does not influence sucker rod to be passed through, and cuts R-joining around the protective hat to the top, the slot degree of depth is protective hat height 2/3-3/4, and slot opens can be by oil stream, piston.The protective hat effect is in production, well workover or silt particle is dropped on when stopping well to enter on the protective hat in the urceolus (8), prevent that silt particle from entering wearing and tearing or card piston in the pump barrel.Form the pump preventer by block, protective hat, interior pipe, urceolus, pump centralizer.At pump barrel outside mounted pump centralizer (9), the pump centralizer is the cirque body of outside trough of belt, can adorn a plurality ofly, and effect is to set upright the oil well pump pump barrel.Rib-loop is connected and fixed the outer rib-loop in valve (12) upper end in the pump barrel lower end system, and standing valve is a steel cylinder, and rib-loop in each system of upper and lower end is outer is placed ball and seat in it, structure with now use identically, rib-loop is connected with interior rib-loop on the lower contact (13) outside its lower end.Urceolus (8) is a steel pipe, and rib-loop is connected with the outer rib-loop of the following upper end of upper connection (4) lower contact (12) in the upper and lower end system.Place seal ring (11) respectively in the outer rib-loop root system groove on upper connection (4) lower contact (12) down, seal ring (11) is the flexible body material, seals.Upper connection is a upper end undergauge ring steel pipe, the inside and outside rib-loop of upper and lower end system, and rib-loop connects oil pipe on the pump in the upper connection, lower contact (12) is a lower end undergauge cirque body, rib-loop in the inboard system in its upper end, the outer rib-loop of outside system, outer rib-loop root system groove, the outer rib-loop of the outside, lower end system.Rib-loop is connected with the outer rib-loop of lower contact in the inboard system in urceolus lower end.Rib-loop connects the interior rib-loop of oil pipe under the pump outside the lower contact lower end.This spline structure makes oil well pump work the time be in free state, prevents to place in the transportation bending of colliding with of improper oil well pump, causes oil well pump work undesired.The bending deflection of spraining after oil well pump is gone into the well when preventing that hole diameter is crooked causes oil well pump work undesired.The space is the sand setting space between pump barrel and the urceolus.
Two embodiments of this invention: this installs each rib-loop Placement and also can be connected by welding or alternate manner.
Three embodiments of this invention: the pump centralizer also can be set upright by jump ring or alternate manner.
