Technical field the utility model is newly succeeded in developing, and it relates to a kind of compound well negative pressure branch that is used for the compound well oil recovery of oil field development and adopts extracting device of oil, belongs to petroleum recovering machinery class.
Background technology is present, the compound well production technique overwhelming majority is used in the economy exploitation of low pressure and low permeability oil reservoir, these reservoir formation energy are low, the fluid supply capacity deficiency, proposed higher requirement for compound well oil recovery technique, for improving exploitation effect, avoid inner loop, the well of different pressures system must be divided the well exploitation.But also there are many aspects that haves much room for improvement in this technology at present, require to use double tube to recover the oil such as realizing that compound well branch is adopted, and the well number that can meet the demands is also very limited.
The summary of the invention the purpose of this utility model provides a kind of compound well negative pressure branch that is used for the compound well oil recovery of oil field development and adopts extracting device of oil.The purpose of this utility model is achieved in that it is by sleeve pipe (1), oil pipe (2), last positioning and directing head (3), packer (4), hollow rod (5), following valve (6), plunger (7), ball-and-seat (8), pressure limiting packer (9), ring-like plunger (10), inner oil tube (11), single flow valve (12), movable porous ring valve (13), standing valve (14) and interior sucker rod (15) are formed, its assembled relation is: go up positioning and directing head (3), oil pipe (2) connects as one with packer (4), packer (4) is on last positioning and directing head (3), and seat is enclosed on the sleeve pipe (1), last positioning and directing head (3) and packer (4) are enclosed within oil pipe (2) outside, following valve (6) is in oil pipe (2) bottom, on the middle part of oil pipe (2) and top over against well A, there are two ball-and-seats (8) position of C, hollow rod (5) and plunger (7) are in oil pipe (2) the inside, ball-and-seat (8) is arranged at the bottom of hollow rod (5), plunger (7) be connected hollow rod (5) below, movable porous ring valve (13) seat is on packer (4), hollow rod (5) is by movable porous ring valve (13), single flow valve (12) is fixed on the interior sucker rod (15), inner oil tube (11) is fixed on positioning and directing head (3) inclined-plane and the packer (4), in interior sucker rod (15) bottom is ring-like capable plunger (10), the A well over against oil pipe (2) and the annular space of sleeve pipe (1) respectively settle a pressure limiting packer (9) up and down, standing valve (14) is connected in inner oil tube (11) bottom.
The utility model is owing to adopt upward positioning and directing head (3), packer (4), hollow rod (5), inner oil tube (11), single flow valve (12), movable porous ring valve (13), interior sucker rod (15), make full use of it and constitute relatively independent oil flow channel, by moving up and down of hollow rod, driving interior sucker rod (15) fixed thereon and plunger (7) moves up and down, change the volume size of each passage, to change channel inner pressure, under suction function, realize the pumping and the lifting of the crude oil of each well.
The utility model is simple in structure, and is practical and convenient, can examine pump at any time, adapt to the requirement of oil production technology prioritization scheme, adjustable stroke, but non-tubing oil extraction, there is oil pipe to recover the oil, can adapt to the requirement of various oil producing operation measures, be that the compound well negative pressure branch in a kind of good oil field development is adopted extracting device of oil.
Description of drawings Fig. 1 is that compound well negative pressure branch is adopted the extracting device of oil schematic diagram.Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
The specific embodiment compound well negative pressure branch is as shown in Figure 1 adopted extracting device of oil, is made up of sleeve pipe 1, oil pipe 2, last positioning and directing head 3, packer 4, hollow rod 5, following valve 6, plunger 7, ball-and-seat 8, pressure limiting packer 9, ring-like plunger 10, inner oil tube 11, single flow valve 12, movable porous ring valve 13, standing valve 14 and interior sucker rod 15.This device forms 3 relatively independent oil flow channels altogether: (1) hollow rod passage, by valve 6, plunger 7, hollow rod 5, ball-and-seat 8 are formed down; (2) hollow rod and oil pipe annulus access are made up of plunger 7, ball-and-seat 8, pressure limiting packer 9, single flow valve 12, movable porous ring valve 13; (3) inner oil tube passage is made up of oil pipe 2, inner oil tube 11, interior sucker rod 15, standing valve 14, ball-and-seat 8, ring-like plunger 10, movable porous ring valve 13.For passage (1), oil stream gives rise in the hollow rod 5 by plunger 7, enters top oil pipe (being sleeve pipe during non-tubing oil extraction) again, realizes the oil recovery of well B.For passage (2), interior sucker rod 15 upper ends are fixing with hollow rod 5 by single flow valve 12, with inner oil tube 11 movable sealings, the lower end is by ring-like plunger 10 and oil pipe 2 movable sealings, when passage (1) recovered the oil, sucker rod 15 moved up and down in hollow rod 5 drove, and changed the size of the volume space of passage (2), form negative pressure, realize crude oil pumping and the lifting process of well C.For passage (3), when other passage recovered the oil, interior sucker rod 15 moved up and down with hollow rod 5, change the size of the volume space of passage (3), form negative pressure, realize crude oil pumping and the lifting process of well A, each passage oil stream converges at top oil pipe (or sleeve pipe).Movable porous ring valve 13 has two annulus holes and a circular hole, respectively as the up and down passage of well A, C oil flow channel and hollow rod 5.Oil pipe in the system can be connected to well head, at this moment, does not need movable porous ring valve 13.The inclined-plane of last positioning and directing head 3 cooperates with the inclined-plane that is reserved in the well bore casing top, realizes that the location of bottom flow string hangs.
