Description
Technical field
This utility model relates to a kind of petroleum industry drilling equipment, particularly relates to a kind of foam of drilling fluid capable of circulation and occurs
Device.
Background technology
When oil drilling, being often required to configure the foam drilling fluid that can be recycled, existing is all by various for addition process
The base slurry of agent and foaming agent is placed in foaming vessel, makes air starch mixed foaming, shape with base by the equipment such as vibrosieve, agitator
Becoming stable microbubble foam drilling fluid, existing agitator is all that the rotation by stirring-head is foamed, inefficient, in order to quickly obtain
Micro-foam drilling fluid, is the most all to increase foaming agent ratio to realize, virtually causes the waste of foaming agent.The problem still exists
During the circulation foaming of, micro-foam drilling fluid uses, when pulling out of hole, when running into down hole problem, in addition it is also necessary to drilling fluid
Carrying out defoaming treatment, defoaming treatment is all to use addition defoamer to realize, and during preparation, foaming agent usage amount means that greatly and disappears
During bubble, defoamer consumption also to strengthen accordingly, until under get into the end normally creep into time, again drilling fluid is carried out foaming process, in order to
Improve drilling fluid foam performance and add foaming agent again,
Addition inorganic agent foaming the most repeatedly, froth breaking, not only cause processing the drilling fluid time long, waste inorganic agent, also
Can affect the foam performance in drilling fluid later stage, the consumption of material also can increase environmental pressure, and this problem still awaits further
Innovation is solved.
Utility model content
A kind of foam of drilling fluid generating means capable of circulation is provided in order to solve the problems referred to above this utility model.
The technical solution adopted in the utility model is: a kind of foam of drilling fluid generating means capable of circulation, it is characterised in that bag
Including urceolus and inner core, urceolus is that tubular two ends are provided with closure, and outer tube side wall left end is provided with base slurry entrance, and outer tube side wall right-hand member is provided with
Foam outlet, is provided with one and is penetrated, by the closure of urceolus left end, the air inlet pipe extending in urceolus on the left of urceolus, air inlet pipe is provided with valve
Door, inner core is that tubular is placed in outer barrel and consistent with urceolus direction, possesses spacing, the inner core right side between inner tank theca and outer tube inner wall
End is provided with closure, and inner core left end is connected with air inlet pipe, and pore is distributed on inner tube wall.
Further, described foam outlet is connected by pipeline has foaming vessel, foaming vessel to be provided with blender, stirring
Facility have the stirring-head stretching into foaming vessel of a connection power source.
Further, described inner core is cylinder type tube or prism type tube.
Further, described urceolus horizontal positioned, the spacing above inner tank theca and between outer tube inner wall is more than inner tank theca
Spacing between lower section and outer tube inner wall.
Further, described urceolus vertically place foam outlet be positioned at base slurry entrance top.
Further, described pore pointing direction tilts to base slurry entrance side.
Further, on pore, connection has trachea.
When this utility model uses, air inlet pipe connects gases at high pressure, and base slurry entrance connects high pressure base slurry, flow into the base slurry of urceolus to
Flowing in foam outlet direction, in base slurry flow process, the gases at high pressure with the ejection of inner core pore constantly collide mixed foaming, so
After flowed out by foam outlet, foaming efficiently quickly, can save the usage amount of foaming agent, can also reduce helping of defoamer simultaneously
The consumption of agent, improves service life and the performance of drilling fluid.
Accompanying drawing explanation
Fig. 1 is this utility model embodiment overview.
Fig. 2 is this utility model embodiment inner/outer tube position sectional view.
Reference: 1 urceolus；2 inner cores；3 base slurry entrances；4 foam outlets；5 air inlet pipe；6 valves；7 pores.
Detailed description of the invention
As shown in Figure 1, 2, this foam of drilling fluid generating means capable of circulation is provided with urceolus 1 and inner core to this utility model embodiment
2, urceolus is provided with closure for cylindric two ends, and outer tube side wall left end is provided with base slurry entrance 3, and outer tube side wall right-hand member is provided with foam outlet
4, it is provided with one on the left of urceolus and is penetrated, by the closure of urceolus left end, the air inlet pipe 5 extended in urceolus, air inlet pipe is provided with valve 6, can
With opening and closing and regulation flow, inner core is that cylindrical shape is placed in outer barrel and consistent with urceolus direction, inner tank theca and outer tube inner wall
Between possess spacing, inner core right-hand member is provided with closure, and inner core left end is connected with air inlet pipe, and pore 7 is distributed on inner tube wall, and this device makes
Used time can plural serial stage, repeatedly foam more efficient, it would however also be possible to employ foam outlet, as prefoam device, is passed through pipeline by one-level
Being connected to another foaming vessel, foaming vessel is provided with blender, and what blender had a connection power source stretches into foaming vessel
Stirring-head, stirring-head can be spiral type or fan blade type.
When this utility model uses, air inlet pipe connects gases at high pressure, and base slurry entrance connects high pressure base slurry, flow into the base slurry of urceolus to
Flowing in foam outlet direction, in base slurry flow process, the gases at high pressure with the ejection of inner core pore constantly collide mixed foaming, so
After flowed out by foam outlet, foaming efficiently quickly, can save the usage amount of foaming agent, can also reduce helping of defoamer simultaneously
The consumption of agent, improves service life and the performance of drilling fluid.
During enforcement, inner/outer tube can be also prism type tube, isolates different spaces, even foaming；Urceolus level during use
Placing and install, the spacing above inner tank theca and between outer tube inner wall, more than the spacing below inner tank theca and between outer tube inner wall, subtracts
Little lower space volume, prevents the sedimentation downwards of base slurry more, can preferably foam；Foam outlet position also can vertically be placed by urceolus
Starch entrance top in base, be that on foam, floating foundation slurry sinks, can even foaming more fully；Pore pointing direction starches entrance to base
Roll tiltedly, the collision of air-flow and base slurry can be improved, preferably foam；Also can connect on pore and have trachea, it is provided that preferably refer to
Tropism.
Being only this utility model preferred embodiment in sum, all equivalences done according to the application are modified and prior art adds
Add and be accordingly to be regarded as this utility model technology category.
