Description
Technical field
The present invention relates to a kind of oil field well mechanical oil recovery device, particularly a kind of energy storage type linear electric motor capsule pump, the special oil well, inclined shaft and the horizontal well that are applicable to general conventional well and contain sand grains, corrosivity well liquid.
Background technique
At present, in petroleum production, sucker rod pumping equipment occupies sizable proportion in oil production system, and the maximal efficiency desired value of rod pumping system is less than 40% at present, and measured value only has 20% left and right.All ground and the underground equipment of traditional ground electric rotating machine sucker rod pumping mode are many, energy loss is large, underground sucker rod with pumping unit joint work, pump load alternately changes and causes ground system work shakiness, aggravate the reactive power consumption of power system, cause the fallback of oil production system, again due to the friction of sucker rod itself and well liquid and with the friction of tube inner wall, cause the loss of huge energy waste and oil pipe and sucker rod, and because well liquid contacts with movement parts, between plunger and pump barrel, wear and tear, seriously corroded, pump detection period is short, particularly be not suitable for high containing sand drain, inclined shaft and horizontal well.
Rodless pump-submersible electric pump directly drives multistage centrifugal pump by the high-speed rotary motor in shaft bottom, and well liquid is lifted to ground.But because motor speed is high, discharge capacity is large, be not suitable for the middle stripper well dominating, and pump efficiency is low, centrifugal blade and pump Inner chamber contact well liquid, damages soon, application area is subject to great limitation.
Generic linear motor oil well pump (existing new technology), the linear motor rotor that utilization is contained in reciprocating pump below drives piston to pump, down stroke drives descent of piston by mover freely falling body, and well liquid enters in pump, and one-half stroke cycle motor is idle not to do work; When upstroke, drive piston stroking upward by mover, well liquid gives rise to ground, motor acting, and motor only has the one-half stroke cycle in acting, and efficiency is low.But because kinematic pair contacts with well liquid, annular clearance between mover and stator is large, although motor has the placed in the middle function of oneself to mover, but stop and falling on bore of stator wall in the stop conversion place mover moment of upper and lower two strokes, again owing to being up stroke discharge opeing, mover axial compression stress adds the bending of ambassador's mover from bottom to top gradually, top at mover is especially serious, the part of leaving bore of stator at mover is even more serious, and the accident of damaging motor in all trouble shootings because mover is bending accounts for the overwhelming majority.
Chinese patent literature number is 1844667A, patent name is " with the down-hole linear motor hydraulic driving capsule oil well pump of balancer weight ", the linear motor rotor that utilization is contained in capsule pump below drives the piston hydraulic oil promoting in oil hydraulic cylinder that pumps flow to or flow out, and forces capsule breathing.Hydraulic oil inhalant liquid cylinder pressure in the time of upstroke, capsule pump expansion trunk liquid enters in capsule pump, counterweight block is also raise simultaneously and has been stored potential energy, in the time of down stroke, hydraulic oil is discharged from oil hydraulic cylinder, capsule pump shrinks well liquid and is extruded capsule pump and gives rise to ground, and counterweight block is also declined simultaneously and discharged potential energy, together to descending piston acting, advantage is kinematic pair and the isolation of well liquid, and mover is not flexible in extended state all the time.But because descending pull bar has occupied piston cross-section area, pump delivery is diminished, counterweight part need to occupy longer space, down-hole, and sealing case remains and is sealed with difficulty.
