Abstract
The utility model discloses a salvageable sealing ball water distributor which consists of a salvaging head (1), a water nozzle (2), a water nozzle seat (3), a sealing ball body (4), a balance guide cone body (5) and a sealing ball seat (6), and is characterized in that a steplike countersunk and a radial water inlet (1a) communicated with the countersunk are formed in the lower part of the salvaging head (1); the lower part of the salvaging head (1) is in threaded connection with the water nozzle seat (3) and the balance guide cone body (5) in sequence; the water nozzle (2) is clamped on an inner shoulder of the steplike countersunk of the salvaging head (1) and the water nozzle seat (3); the upper part of the balance guide cone body (5) adopts a hollow structure; a radial water outlet (5a) communicated with a center hole of the balance guide cone body (5) is formed in the lower part of the balance guide cone body (5); the middle part of the balance guide cone body (5) is sleeved with the sealing ball body (4).
Description
Technical field
The utility model relates to a kind of salvagable ball sealer injection well downhole flow regulator device on a kind of separated-zone water infection oil field well separate injection tubing string.
Background technology
In oil field development, fractional water flooding well water filling layer is nearer apart from artificial bottom of a well, causes eccentric injection mandrel and bottom ball seat distance and position to approach, and in test allocation process, throw in catcher cannot be opened, and causes test crash.Distance between fractional water flooding well packer location and ball seat is too small simultaneously, cannot descend eccentric injection mandrel, causes zonal injection technology failure, affects oil field development.
The patent No. is that the patent of 200620025776.x discloses a kind of Retrievable tee water distributor, formed by blanking plug, main body cover, water nozzle seat and check ball seat, wherein blanking plug is provided with water nozzle seat and check ball seat formation one, and blanking plug can be pulled out or drop into and change from main body cover.Water nozzle seat and check ball seat form one, and water nozzle seat, because cannot seal by injected water erosion corrosion, affects water injection well water filling, need to carry injection well pipe column, carry out operation replacing water and chew seat, have increased workload; Distance between packer location and Retrievable tee water distributor is too small, cannot descend throw in catcher to salvage blanking plug, causes and cannot test.
Summary of the invention
The defect that the purpose of this utility model exists in order to overcome above-mentioned prior art, provides a kind of salvagable ball sealer injection well downhole flow regulator device.
The technical scheme that the utility model adopts is:
The utility model is made up of fishing head, water nozzle, water nozzle seat, sealed spheroid, sealed ball seat, balance starting taper body, the radially inlet opening that fishing head bottom is provided with stepped counterbore and is communicated with this counterbore, fishing head bottom be threaded successively water nozzle seat, balance starting taper body; Water nozzle is connected to interior shoulder and the water nozzle seat of the stepped counterbore of fishing head; Balance starting taper body top is hollow-core construction, and its underpart has the radially weep hole communicating with the centre bore of balanced body starting taper, and the middle part cover of balance starting taper body has sealed spheroid.
The beneficial effects of the utility model are, be lowered to this utility model device, having solved that eccentric injection mandrel and bottom ball seat distance and position approach cannot pulling problem, has solved that distance between water injection well packer position and ball seat is too small cannot descend eccentric injection mandrel problem simultaneously.The eccentric injection mandrel that also can be used for fractional water flooding well orlop pulling failure is effectively alternative.
accompanying drawing explanation:
Fig. 1 is sectional view of the present utility model.
1. fishing heads in figure; 2. water nozzle; 3. water nozzle seat; 4. sealed spheroid; 5. balanced body starting taper; 6. sealed ball seat; 7. oil pipe.
The specific embodiment
The utility model is made up of fishing head 1, water nozzle 2, water nozzle seat 3, sealed spheroid 4, balance starting taper body 5, sealed ball seat 6, the radially inlet opening 1a that fishing head 1 bottom is provided with stepped counterbore and is communicated with this counterbore, fishing head 1 bottom be threaded successively water nozzle seat 3, balance starting taper body 5; Water nozzle 2 is connected to interior shoulder and the water nozzle seat 3 of the stepped counterbore of fishing head 1; Balance starting taper body 5 tops are hollow-core construction, and its underpart has the radially weep hole 5a communicating with the centre bore of balanced body starting taper 5, and the middle part cover of balance starting taper body 5 has sealed spheroid 4.
Radially water inlet 1a on described fishing head 1 is symmetrical uniform hole.
Radially weep hole 5a on described balance starting taper body 5 is symmetrical uniform hole.
Under water injection well operation, when oil pipe, sealed ball seat 6 is lowered to job design depth location with oil pipe 7.After operation completion, this utility model device packs stagnant water mouth into, drops in water injection well, sits on sealed ball seat 6.According to geology waterflooding requirement, on well testing truck, to carry and salvage this utility model device, the water nozzle that replaced on ground is corresponding size, allocates.When water filling, sealed spheroid 4 is seated on sealed ball seat 5, forms sealing and guarantees that outside enters oil jacket annular space without injected water; Injected water is by inlet opening 1a on fishing head 1, enter fishing head 1 bottom and water nozzle seat 3 and form space, produce chock pressure difference through water nozzle 2, enter balanced body starting taper 5 internal channels through water nozzle seat 3 inner via holes, by starting taper 5 outer wall, equally distributed weep hole 5a enters water filling layer position.On well testing truck, carry and salvage this utility model device and solved and avoid using throw in catcher cannot salvage blanking plug problem.Water nozzle seat 3 corrodes blow-by, above carries and salvages this utility model device, and replaced on ground water nozzle seat 3, avoids upper lifting pipe post to change water nozzle seat 3.
Claims (3)
1. a salvagable ball sealer injection well downhole flow regulator, formed by fishing head (1), water nozzle (2), water nozzle seat (3), sealed spheroid (4), balance starting taper body (5), sealed ball seat (6), it is characterized in that: the radially inlet opening (1a) that fishing head (1) bottom is provided with stepped counterbore and is communicated with this counterbore, fishing head (1) bottom be threaded successively water nozzle seat (3), balance starting taper body (5); Water nozzle (2) is connected to interior shoulder and the water nozzle seat (3) of the stepped counterbore of fishing head (1); Balance starting taper body (5) top is hollow-core construction, and its underpart has the radially weep hole (5a) communicating with the centre bore of balanced body starting taper (5), and the middle part cover of balance starting taper body (5) has sealed spheroid (4).
