Abstract
The invention discloses a throw-out seal-inserted air injection tubular column, comprising working cylinder, packer, level pressure ball valve, sieve tube and thread stopper, and also comprising seal plug, throwing hand recovery cylinder and disc valve controller connected in turn at the lower end of the working cylinder as well as at the upper end of the packer, and the lower end of the packer is connected with level pressure ball valve, sieve tube and thread stopper. The invention is convenient, reliable and safe, and has a function of closing or opening according to need, and applies to air injection process of petroleum producing.
Description
One, technical field
The present invention relates to the oil exploitation down-hole string, particularly a kind of releasing gadget sealing insertion head gas-injection tube pile.
Two, background technology
Existing oil exploitation gas injection tubing string is generally used conventional flow string or import tubing string, but all exists separately shortcoming or deficiency: 1. the import tubing string adopts permanent packer, can not take out, can only bore, so the application cost height; 2. domestic tubing string gas tightness is poor, and is withstand voltage low, has only 10-15Mpa; 3. domestic tubing string does not have the down-hole blowout hookup, needs kill-job during lift pipe string, and complex procedures and polluted reservoir as not kill-job well take place easily then and overflow or blowout, cause environment pollution and have potential safety hazard.
Three, summary of the invention
The purpose of this invention is to provide a kind of releasing gadget sealing insertion head gas-injection tube pile, shortcoming or deficiency that it can overcome effectively or avoid existing in the above-mentioned prior art solve closing and connectivity problem of oil pipe in case of necessity effectively, thereby guarantee the safety of gas injection well operation.
Releasing gadget sealing insertion head gas-injection tube pile of the present invention, comprise seating nipple, packer, level pressure ball valve, screen casing and plug, also comprise sealing plug, give up tieback tube and dish valve control that described seating nipple lower end and packer upper end are connected in turn, described packer lower end is connected with level pressure ball valve, screen casing and plug in turn.
Wherein, described sealing plug comprise seal receptacle and on baffle ring, seal and the top connection of installing, the close plug in guide peg that the other end connects.Described dish valve control comprises the seal nipple that adapter sleeve and lower end thereof connect, the valve seat of installing in the upper end, " L " shape seal and top connection, the dish valve plate of installing on the valve seat and torsion spring pin and torsion spring.Described top connection and " L " shape seal lower end are toroidal, match with the dish valve plate, form the soft or hard double containment.The described tieback tube of giving up comprises the fishing head that lock dog seat, lock dog and ball seat that sealing drum and inner chamber thereof install are closely inserted, the lower end is connected, and lock dog seat and sealing drum are fixed by lock dog, and ball seat is close is slottingly located by control nail mutually with the lock dog seat.
The present invention has following advantage or beneficial effect compared with prior art:
1, design has the dish valve control, can close or be communicated with tubing string as required automatically;
2, flow chart is simple, and is easy to use, need not the well killing fluid kill-job, can prevent oil layer pollution, and full well casing post can trip out easily, need not to bore the miller preface;
3, gas injection well job safety, blowout prevention, anti-overflow, the pressure-bearing height can withstand voltage 30-50Mpa.
Four, description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is by sealing plug structural representation shown in Figure 1,
Fig. 3 is by the tieback barrel structure schematic diagram of giving up shown in Figure 1,
Fig. 4 is for pressing dish valve control structural representation shown in Figure 1.
Five, the specific embodiment
Consult Fig. 1-Fig. 3, a kind of releasing gadget sealing insertion head gas-injection tube pile, comprise seating nipple 1, packer 5, level pressure ball valve 6, screen casing 7 and plug 8, also comprise sealing plug 2, give up tieback tube 3 and dish valve control 4 that described seating nipple 1 lower end and packer 5 upper ends are connected in turn, packer 5 lower ends are connected with level pressure ball valve 6, screen casing 7 and plug 8 in turn.
