Abstract
The utility model relates to a kind of hydraulic pulse generators, including cylinder, cradle, normally open valve, impeller, mandrel, wheel valve, diaphragm valve, nozzle, baffle, it is characterized in that being equipped with baffle in the inner cavity of cylinder, nozzle is installed above baffle, the side of normally open valve is equipped with impeller, and the center of impeller is provided with mandrel, wheel valve is provided with below mandrel, impeller and wheel valve are same mandrel, and the other side of the nozzle below cylinder is provided with diaphragm valve.The utility model has the beneficial effects that not increasing workload, and the water attack impulse wave generated in the case where not changing original cementing design, propagation distance is remote, influences very little to borehole wall stability, convenient and practical.
Description
Technical field
The utility model relates to act on the borehole wall, sleeve outer wall and cement medium itself in petroleum industry, improve cement
Replacement efficiency is starched, curing time is shortened, prevents formation fluid annular space from altering slot, improves grout cures intensity and interface agglutination matter
The device of amount, specifically a kind of hydraulic pulse generator.
Background technique
Hydraulic vibrating apparatus used at present, it is larger near tools amplitude, serious, the hydrodynamic wave (H wave) of generation is damaged to the borehole wall
Propagation distance is very short, and the influence to cement slurry is limited.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of waterpower pulse generation
Device, the technical scheme adopted by the utility model to solve the technical problem is as follows: the structure of the utility model includes cylinder, support
Seat, normally open valve, impeller, mandrel, wheel valve, diaphragm valve, nozzle, baffle, it is characterised in that baffle is installed in the inner cavity of cylinder, is kept off
Nozzle is installed, the side of normally open valve is equipped with impeller, and the center of impeller is provided with mandrel, the lower section of mandrel above plate
It is provided with wheel valve, impeller and wheel valve are same mandrel, and the other side of the nozzle below cylinder is provided with diaphragm valve.
Assemble method: cylinder is stood upside down, and outward buckle downward, first in the cavity of the barrel by baffle installation, is then installed again
Two nozzles；Normally open valve, impeller, mandrel, wheel valve and diaphragm valve are installed together by drawing, then the inner cavity of cylinder is installed
In, cradle is finally installed, above fastens and finishes.
The utility model has the beneficial effects that do not increase workload in the case where not changing original cementing design, and
And the water attack impulse wave generated, propagation distance is remote, influences very little to borehole wall stability, convenient and practical.

Fig. 2: the utility model impeller B-B to schematic cross-sectional view.
Fig. 3: the utility model impeller C-C to schematic cross-sectional view.
Fig. 4: utility model works theory structure schematic diagram.
In figure: cylinder 1, cradle 2, normally open valve 3, impeller 4, mandrel 5, wheel valve 6, diaphragm valve 7, nozzle 8, baffle 9.
Specific embodiment
It is described with reference to make the utility model detailed description in detail below；As shown in the picture, the utility model
Structure includes cylinder 1, cradle 2, normally open valve 3, impeller 4, mandrel 5, wheel valve 6, diaphragm valve 7, nozzle 8, baffle 9, and feature exists
Baffle 9 is installed in the inner cavity of cylinder 1, the top of baffle 9 is equipped with nozzle 8, and the side of normally open valve 3 is equipped with impeller 4, leaf
The center of wheel 4 is provided with mandrel 5, and the lower section of mandrel 5 is provided with wheel valve 6, and impeller 4 and wheel valve 6 are same mandrel 5, cylinder 1
The other side of the nozzle 8 of lower section is provided with diaphragm valve 7.
Assemble method: cylinder 1 is stood upside down, and baffle 9 downward, is mounted in the inner cavity of cylinder 1 first, then pacifies again by outward buckle
Fill two nozzles 8；Normally open valve 3, impeller 4, mandrel 5, wheel valve 6 and diaphragm valve 7 are installed together by drawing, then cylinder is installed
In 1 inner cavity, cradle 2 is finally installed, above fastens and finishes.
Working principle: when well cementing liquid passes through impeller 4, impeller 4 rotates, while the wheel valve 6 of same mandrel 5 being driven to revolve
Turn, when wheel valve 6 goes to the valve road inlet b, the valve road of diaphragm valve 7 is closed, when leaving valve road B entrance, the valve road of diaphragm valve 7
It opens, generates surge wave, surge wave is upwardly propagated by shaft bottom along casing annulus, fulfiled assignment.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel conception and scope is defined, without departing from the design concept of the present utility model, ordinary skill in this field
The all variations and modifications that technical staff makes the technical solution of the utility model should all fall into the protection model of the utility model
It encloses, technical content requested for protection of the utility model is all described in the claims.
