Description
Technical field
The utility model belongs to petroleum industry machinery oil production equipment or instrument, is particularly well-suited to industrial extracting device of oil
A kind of 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 desert water deficient regions, geothermal energy resources drilling well etc. just cannot work or drilling cost is too high,
The U.S. 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.
Content of the invention
In order to overcome the design defect of prior art, the utility model provides a kind of foam screw rod drilling well underground device, this
Real
Simple, easy to use, with low cost, aboundresources, elegant in appearance, the new brill of suitable well site of oil field with novel operating
Visit
Construction requirements.
The utility model solves its technical problem and be employed technical scheme comprise that：Mainly by drill bit, underground air hammer, connect
Screw rod, resistance absorber, bumper jar, damper, inner blowout preventer, Explosion proof joint, downhole blow-out preventer, wellhead connection device are formed, and bore
Head is arranged on the bottom of underground air hammer, and underground air hammer is connected with resistance absorber by connecting screw rod, and resistance absorber upper end is equipped with shake
Hit device, bumper jar upper end connects equipped with well head equipped with downhole blow-out preventer, downhole blow-out preventer upper end equipped with damper, damper upper end
Device, wellhead connection device is connected with well mouth rotary head.
The utility model compact conformation rationally, long service life, reduce maintenance cost, reduce use cost, and have with
Lower feature：
1st, the utility model can reduce leakage and the risk of differential sticking.
2nd, this utility model is conducive to deviation prevention and fast, because bottom rock is " pushed " towards in well under negative pressure condition, therefore
The pressure of the drill needed for rock " crushing " is less, generally the 1/3 of conventional drilling.
3rd, the utility model extends bit life, and air drilling requirement gas returns speed in annular space and must reach 15m/s
（3000ft/min）More than, make drilling cuttings rapidly depart from the cutting part of drill bit completely, it is to avoid Repeated Cutting is it is ensured that well
Cleaning.
Brief description
Accompanying drawing 1 is structural representation of the present utility model.
In figure：1st, drill bit, 2, underground air hammer, 3, connecting screw rod, 4, resistance absorber, 5, bumper jar, 6, damper, 7, interior anti-
Spray apparatus, 8, Explosion proof joint, 9, downhole blow-out preventer, 10, wellhead connection device.
Specific embodiment
For disclosing the technical solution of the utility model further, made specifically by embodiment with reference to Figure of description
Bright：
The utility model is mainly by drill bit, underground air hammer, connecting screw rod, resistance absorber, bumper jar, damper, interior blowout prevention
Device, Explosion proof joint, downhole blow-out preventer, wellhead connection device are formed, and drill bit is arranged on the bottom of underground air hammer, and down-hole is empty
Pneumatic hammer is connected with resistance absorber by connecting screw rod, resistance absorber upper end equipped with bumper jar, bumper jar upper end equipped with damper, on damper
Equipped with downhole blow-out preventer, downhole blow-out preventer upper end is connected with well mouth rotary head equipped with wellhead connection device, wellhead connection device at end.
Normal need to produce with ground gas when drilling and injected system, Wellhead Control System, data monitoring and acquisition system,
Ground environmental protection and piece-rate system auxiliary work, complete foam drilling operation.
