Description
Technical field
The utility model relates to a kind of proof adjustable and returns and tell blanking plug.
Background technology
Current oil-field flooding tubing string many employings eccentric injection mandrel tubing string, eccentric injection mandrel is built-in with blanking plug, controls water injection rate by blanking plug.And current blanking plug is because reasons in structure is when water distribution, due to the change of water injection pressure, also the change of water injection rate is caused, cause water filling and adjust out of control, the workload of down-hole water transfer increases, and affects water filling quality, thus labor strength increases, cost increase, claim for eot, have impact on normal production.
Summary of the invention
The purpose of this utility model is that proposition one has and prevents telling function, and the proof adjustable that can change water injection rate returns tells blanking plug.
The purpose of this utility model is achieved in that proof adjustable returns and tells blanking plug and comprise main body, and to spin pressure cap in main body upper port, spin in pressure cap opening nut, and fishing head penetrates in pressure cap.In main body, be provided with cam holder, it is equiped with bearing pin, bearing pin installs cam, between bearing pin and main body, cover has torsion spring.Be provided with spring between cam holder and pressure cap, cam holder top and positioning sleeve contact, and positioning sleeve top and fishing head contact.To spin seating nipple in lower body part, seating nipple center is provided with a leading screw, leading screw top is connected with fishing head bottom, leading screw lower end is fixed with spool by screw, and spool overcoat has valve seat assembly, and spin guide head in seating nipple lower port, water stream channel is provided with in guide head, water stream channel inner port place is provided with valve ball, and valve ball and support contact, and support and valve seat assembly contact.
The application is relative to conventional blanking plug, the difference maximum with it is to add anti-function of telling and the adjustment can also carrying out water nozzle aperture, well can solve water injection well and enter blanking plug blocking water filling port due to strata pressure higher than impurity such as stratum greasy dirt, the grains of sand during water injection pressure, affect the water-injection efficiency of water injection well.Can also realize underground to enter measurement and adjustment instrument adjusted simultaneously, changes the water filling water yield.
Accompanying drawing illustrates: the technical solution of the utility model is provided by following drawings and Examples:
Fig. 1 is that proof adjustable returns and tells plug structure schematic diagram.

Detailed description of the invention: the present invention by the restriction of following embodiment, can not determine concrete embodiment according to technical scheme of the present invention and actual conditions.
Embodiment: as shown in Figure 1, proof adjustable returns to be told blanking plug and comprises main body 6, and to spin pressure cap 4 in main body 6 upper port, spin in pressure cap 4 opening nut 2, and fishing head 1 penetrates in pressure cap 4.In main body 6, be provided with cam holder 8, it be equiped with bearing pin 10, bearing pin 10 is installed cam 11, between bearing pin 10 and main body 6, cover has torsion spring 9.Be provided with spring 5 between cam holder 8 and pressure cap 4, cam holder 8 top and positioning sleeve 7 contact, and positioning sleeve 7 top and fishing head 1 contact.Spin in main body 6 bottom seating nipple 14, seating nipple 14 center is provided with a leading screw 15, leading screw 15 top is connected with fishing head 1 bottom, leading screw 15 lower end is fixed with spool 17 by screw 18, and spool 17 overcoat has valve seat assembly 19, and circumfili thick stick 15 bottom is provided with a card rib, card rib upper and lower side place cover has upper and lower press spring base 12,16, upper and lower press spring base 12,16 outer socket stage clip 13, two stage clip 13 one end and upper and lower press spring base 12,16 contact, and the other end contacts with main body 6 and valve seat assembly 19 respectively.Spin guide head 20 in seating nipple 14 lower port, is provided with water stream channel in guide head 20, and water stream channel inner port place is provided with valve ball 22, and valve ball 22 and support 23 contact, and support 23 and valve seat assembly 19 contact.
Opening nut 2 offers pin-and-hole 3.
To spin portion at seating nipple 14 and guide head 20, and be provided with sealing ring 21 in the middle part of guide head 20.
Be two terrace with edge structures in described seating nipple 14 lower port, valve seat assembly 19 external surface is provided with card rib, contacts the terrace with edge place, inner side at aforementioned two terrace with edges, and guide head 20 external surface is also provided with card rib and contacts terrace with edge place, outside at aforementioned two terrace with edges.
Described valve seat assembly 19 is cavity cylinder, its open at one end, and the other end is semiclosed, and semiclosed end is water inlet, and this water inlet is towards guide head 20.Described spool 17 is filled in valve seat assembly 19, and its diameter is equal with valve seat assembly 19 internal diameter, and volume is less than valve seat assembly 19 internal cavity volume.
In use, by twisting fishing head 1, drive the flexible of leading screw 15, thus band movable valve plug 17, valve seat assembly 19 are mobile in seating nipple 14, and then making support 23 loosen compressing to valve ball 22, the aperture realizing water nozzle in guide head 20 regulates, and changes water injection rate.When strata pressure is higher than water injection pressure, valve ball closes guide head 20, prevents formation fluid and impurity to flow into seating nipple 14, also namely prevents from entering in pit shaft.
Constitute most preferred embodiment of the present utility model at above technical characteristic, relevant art feature can be increased and decreased according to actual needs.
