Description
Technical field
The utility model belongs to geological drilling technology field, and in particular to reacting cycle drills method equipment.
Background technology
It is a kind of new that reacting cycle drilling technique is accompanied by the development of direct circulation drilling technique and accordingly grown up
Drilling method, because under certain conditions, reacting cycle has advantages more more than direct circulation drilling method, can obtain preferably
Economic effect, therefore, has obtained developing on a large scale very much in recent years, application surface progressively expands.
Reacting cycle drilling technique be drilling fluid from aperture through between drilling rod and hole wall or between the inner and outer pipes of double-wall drill pipe
Annulus to descending, reach a kind of opposite direction circulation returned again from drilling rod or double-wall drill pipe inner tube after bottom hole to earth's surface
The probing of mode and sampling technique.It can be water, mud or air to rinse liquid medium.
40~fifties of 20th century, reacting cycle drilling technique starts to rise in Holland, Germany, the world is generalized to quickly each
Ground, and the reacting cycle drilling technique of diversified forms is occurred in that in succession.The reacting cycle probing at initial stage can only take rock ore deposit to consider to be worth doing.In recent years
Rock successfully can be continuously taken using anti-spy trepan technology of following in geological drilling（Ore deposit）The heart.When reacting cycle is drilled, due to punching
Medium is washed in drilling rod centre bore at full speed to rise, therefore the ability of discharge drilling cuttings is strong, drilling cuttings particle diameter is big, weight of the drilling cuttings in bottom hole
It is multiple broken few, drilling efficiency can be increased substantially, particularly effect is obvious in large diameter drilling.
Reacting cycle drilling technique mainly has following several：
Pump breath countercirculate：
Groundwork machinery is a gravel pump, the suction pressure subatmospheric power when sandstone pump work, and it is maximum
Value is referred to as the vacuum of gravel pump.Hole interior circulation medium produces endless form under atmospheric pressure effect.It drives flushing medium flow
Dynamic pressure is referred to as driving pressure, and the pressure is equal to the vacuum of pump, therefore it is required that gravel pump used will have higher vacuum.
The air first discharged with vavuum pump or charge pump during sandstone pump startup in gravel pump and pipeline could start work.
Jet reacting cycle：
During work by working barrel it is defeated Lai highly pressurised liquid form high-speed jet by the nozzle of jet pump, make the suction of jet pump
Entrance forms flushing liquor in subatmospheric low-pressure area, hole and is pumped into jet pump under atmospheric pressure effect.Its circulation side
Formula and principle are similar to Pump breath countercirculate.For Pump breath countercirculate and jet reacting cycle, when gravel pump and jet pump are located at earth's surface
When, vacuum of its driving pressure equivalent to pump, it is impossible to more than 1 atmospheric pressure, therefore it is only applicable to the probing of shallow bore hole reacting cycle.This
Two kinds of reacting cycle facilities can be designed to it is positive and negative follow it is dual-purpose, so as to for purging line block and adapt to Different Strata drilling technology
The need for.
Gas lift reverse circulation：
Compressed air is mixed through gas distribution channel into mixing chamber with drilling fluid, and ratio is produced in mixing chamber top rod
The less mixing wastewater with air stream of weight, and the outer flushing liquor of mixing chamber above drilling rod is due to being not incorporated into air, therefore proportion is larger, so
Inside and outside water column produces pressure differential because proportion is different, and flushing liquor mode as shown in Fig. 2 arrows is circulated under the effect of this pressure differential.
Its driving pressure increases and increased with mixing chamber submersible depth, when submersible depth is little, and discharge landwaste is inefficient, submersible depth
Work abnormal during less than 15 meters, therefore gas lift reverse circulation is often applied in combination with other endless form.When using pressure-air compression
It can increase submersible depth during machine, so that driving pressure increases, therefore deeper hole can be bored.
Hollow-through air dth hammer reacting cycle drills method：
Hollow-through air dth hammer is equipped with double-wall drill pipe, and compressed air discharges air-flow in the negative pressuren zone of drill bit base bleed mouthful
Speed is high, and close to subsonic speed, powerful suction force and motive force can be produced to rock core, landwaste, solves gravel layer pine for a long time
Scattered stratum can not obtain the problem of enough rock core rock samples.
