Description
Technical field
The invention belongs to petroleum industry machinery oil production equipment or instrument, be particularly well-suited to the one of industry extracting device of oil
Plant foam screw rod drilling well underground device.
Background technology
The oil drilling commonly used at present in China is conventional mud drilling well, if running into severe circulation loss, serious water sensitivity mud
Shale, polar region permafrost band drilling well, the drilling well of water deficient regions, desert, geothermal energy resources drilling well etc. just cannot work or drilling cost is too high,
The U.S. i.e. starts air, foam drilling test early than early fifties.And have developed gas base flow body under-balanced drilling technology, but
Equipment is heavy, cost is high, and popularization and application are slow.
Summary of the invention
In order to overcome the design defect of prior art, the present invention provides a kind of foam screw rod drilling well underground device,
The present invention is simple to operate, easy to use, with low cost, and aboundresources is elegant in appearance, is suitable for well site of oil field new
Probing construction requirements.
The technical solution adopted for the present invention to solve the technical problems is: mainly by drill bit, underground air hammer, connection spiral shell
Bar, resistance absorber, bumper jar, amortisseur, inner blowout preventer, Explosion proof joint, downhole blow-out preventer, wellhead connection device are formed, drill bit
Being arranged on the bottom of underground air hammer, underground air hammer is connected with resistance absorber by connecting screw rod, and resistance absorber upper end is equipped with jarring
Device, bumper jar upper end connects dress equipped with downhole blow-out preventer, downhole blow-out preventer upper end equipped with well head equipped with amortisseur, amortisseur upper end
Putting, wellhead connection device is connected with well mouth rotary head.
Present configuration compact and reasonable, service life is long, reduces maintenance cost, reduces use cost, and has following spy
Point:
1, the present invention can reduce the risk of leakage and differential sticking.
2, this invention is conducive to deviation prevention and fast, and owing to bottom rock is " pushed " towards in well under negative pressure condition, therefore rock is " broken
Broken " needed for the pressure of the drill less, generally the 1/3 of conventional drilling.
3, the present invention extends bit life, and air drilling requires that gas returns speed at annular space and must reach 15m/s(3000ft/
Min) more than, drilling cuttings is made to depart from the cutting part of drill bit the most rapidly, it is to avoid Repeated Cutting, it is ensured that well cleans.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present invention.
In figure: 1, drill bit, 2, underground air hammer, 3, connect screw rod, 4, resistance absorber, 5, bumper jar, 6, amortisseur, 7, interior anti-
Spray apparatus, 8, Explosion proof joint, 9, downhole blow-out preventer, 10, wellhead connection device.
Detailed description of the invention
For the openest technical scheme, made in detail by embodiment below in conjunction with Figure of description
Illustrate:
The present invention mainly by drill bit, underground air hammer, connect screw rod, resistance absorber, bumper jar, amortisseur, inner blowout preventer, explosion-proof connect
Head, downhole blow-out preventer, wellhead connection device are formed, and drill bit is arranged on the bottom of underground air hammer, and underground air hammer is by even
Connecing screw rod to be connected with resistance absorber, resistance absorber upper end is equipped with bumper jar, and bumper jar upper end is equipped with amortisseur, and amortisseur upper end is equipped with well
Lower preventer, downhole blow-out preventer upper end is connected with well mouth rotary head equipped with wellhead connection device, wellhead connection device.
Need to produce with ground gas during normal probing and injected system, Wellhead Control System, data monitoring and acquisition system,
Ground environmental protection and piece-rate system auxiliary work, complete foam drilling operation.
