Abstract
The utility model relates to an auxiliary tool for a sand control oil pump for oil production in an oilfield, which is composed of an upper joint, pins, a sealing ring, a pressure isolation head, an aThe utility model relates to an auxiliary tool for oil sucking pump against sand blocking which consists of an upper joint, a pin, a sealing circle, a separating head, an apical tube, a sealing tube apical canal, a sealed tube and a lower joint, wherein after, a production string of the sand control oil pump with a layered oil pumping string is lowered to a predetermined position, pressure is pumpnd a lower joint. When a sand protection block oil well pump production string with stratification oil extraction tubular pile is under the prearranged position, the oil pipe is pressed and the pressued into the oil pipe, and the pressure enables the isolation head to generate downward thrusting force; after the thrusting force shears the pins, the pressure isolation head is caused to descend, there makes the separating head produce downward thrust which cuts the pin and make the separating head down. The thrust produced by the pressure transmits to the apical tube which pushes the cone at sli thrusting force generated by the pressure is passed to the apical canal, and then, the apical canal pushes a cone arranged on an anti-jacking clip of the layered oil pumping string to enable the antips preventing at the stratification oil extraction tubular pile to move the slips preventing to separate the stratification oil extraction tubular pile from the sand protection block oil well pump pro-jacking clip to move; thus, the layered oil pumping string is separated from the production string of the sand control oil pump, the sand control oil pump is lifted to certain height, and then, produduction string. Then production is possible to lift the sand protection block oil well pump production string to a certain height. When the sand protection block oil well pump is produced, the separatction can be carried out. When sand control oil pump is used for the production, the pressure isolation head seals the inner pressure of an upper sand sinking tail tube, and an oil well can keep normaing head seals the pressure in an upper sand sink tail pipe and the oil well keeps normal oil sucking production. Therefore, after using the tool, the sand protection block oil well pump production stl production of oil pumping. Therefore, after the tool is used. Thus, the pipe string of the sand control oil pump for oil production on a lower branch layer does not need singly descending, the layerring with lower stratification oil extraction is not necessary to make lower sand protection block oil well pump tube string with a single fixed stratification oil extraction. ed oil pumping string is fixed, and then, the sand control oil pumping string is lowered.
Description
One, technical field
Sand control card oil well pump aid belongs to a cover mechanical device of oil field oil recovery industrial technology.
Two, background technology
Common oil well pump is the bottom oil-feed from pump; and sand control card oil well pump is from the oil-feed of pump barrel lateral surface; cause the annular space of oil pipe, sleeve pipe to become oil flow channel; when oil well for some reason during stop pumping; the sand grains of the annular space of oil pipe, sleeve pipe will sink; therefore; sand control card oil well pump pumping pipe string just can not be with packer to carry out oil production by layer; otherwise the sand grains that sinks can bury the bottom pumping pipe string; the problem that sand card tubing string occurs; increase operating cost, also can cause oil well to scrap when serious, produce heavy economic losses.When oil well needs oil production by layer, have only first lower leaf flow string, and separate-layer production string is fixed on the oil reservoir position, and then have the flow string of sand control card oil well pump down.This oil recovery technique flow chart is many, the expense height, and the time is long.
Three, summary of the invention
The purpose of this utility model provides sand control card oil well pump aid, this instrument is connected in down on the separate-layer production string of sand control card oil well pump, separate-layer production string and sand control card oil well pump flow string are thrown off, just can produce carrying certain altitude on the sand control card oil well pump flow string then.Make it need sand control card oil well pump tubing string that lower leaf recovers the oil fixing separate-layer production string of next time separately, and then time sand control card oil well pump tubing string.
The utility model is achieved in that it is by top connection, pin, sealing ring, form every pressure head, push pipe, sealed tube, lower contact.Top connection connects with sealed tube top, and the sealed tube bottom connects with lower contact, and the lower contact bottom connects with anti-jack slips on the separate-layer production string.Every pressure head by dowel fixes in the top connection bottom, be in the top connection every pressure head top, be in the sealed tube every the pressure head bottom, with sealed tube matching relationship is arranged, sealing ring is arranged on pressure head, push pipe with connect every pressure head.
Under the sand control card oil well pump flow string that has separate-layer production string behind the precalculated position, suppress in the oil pipe, the tap of hydraulic pressure on sand control card oil well pump makes every pressure head and produces downward thrust, thrust cut off make every pressure head behind the pin descending, the thrust that pressure produces passes to push pipe, push pipe promotes the cone on the anti-jack slips on the separate-layer production string again, make the anti-jack slips action, separate-layer production string and sand control card oil well pump flow string are thrown off, just can produce carrying certain altitude on the sand control card oil well pump flow string then, when sand card oil well pump was produced, the pressure in pressure head seals up top sand setting tail pipe, oil well kept normal oil pumping to produce.Therefore, the sand control card oil well pump tubing string that recovers the oil of lower leaf fixedly separate-layer production string and then time sand control card oil well pump tubing string of next time separately.
Four, description of drawings
Accompanying drawing is the structure half sectional view of the utility model embodiment.
Among the figure: the 1st, top connection, the 2nd, pin, the 3rd, sealing ring, the 4th, every pressure head, the 5th, push pipe, the 6th, sealed tube, the 7th, lower contact.
Five, the specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in the figure, the utility model is by top connection 1, pin 2, sealing ring 3, form every pressure head 4, push pipe 5, sealed tube 6, lower contact 7.Top connection 1 connects with sealed tube 6 tops, and sealed tube 6 bottoms connect with lower contact 7, and lower contact 7 bottoms connect with anti-jack slips on the separate-layer production string.Be fixed on top connection 1 bottom every pressure head 4 by pin 2, be in the top connection 1, be in the sealed tube 6, matching relationship is arranged, sealing ring 3 is arranged on pressure head 4 with sealed tube 6 every pressure head 4 bottoms every pressure head 4 tops, push pipe 5 with connect every pressure head 4.
Under the sand control card oil well pump flow string that has separate-layer production string behind the precalculated position, suppress in the oil pipe, the tap of hydraulic pressure on sand control card oil well pump, make every pressure head 4 and produce downward thrust, thrust cut off make every pressure head 4 behind the pin 2 descending, the thrust that pressure produces passes to push pipe 5, push pipe 5 promotes the cone on the anti-jack slips on the separate-layer production string again, make the anti-jack slips action, separate-layer production string and sand control card oil well pump flow string are thrown off, just can produce carrying certain altitude on the sand control card oil well pump flow string then, when sand card oil well pump is produced, pressure in pressure head seals up top sand setting tail pipe, oil well keep normal oil pumping to produce.Therefore, the sand control card oil well pump tubing string that recovers the oil of lower leaf fixedly separate-layer production string and then time sand control card oil well pump tubing string of next time separately.
