Abstract
The present invention is a kind of being applied in the oil drilling field, when adopting impact rotating to creep into method, produces a kind of instrument of impact force.Under the fluid effect of certain pressure, the oscillator of its inside sends oscillator signal, and the work of instruction works valve makes the vibration cylinder drive the block stamp vibration, reaches the purpose that drill hammer quickens catalase.Its maximum characteristics are that working life is longer, is applicable to the needs of oil drilling drilling well when flushing liquor is the bigger liquid of grinding pebble degree.To improving rate of penetration, improve drilling quality, reducing drilling cost has remarkable result.
Description
The present invention is applied in the probing field.When adopting impact rotating to creep into method, produce a kind of instrument of impact force.Characteristics are that it can be adapted to the oil drilling that flushing liquor is the bigger mud of grinding pebble degree.
It is the higher boring method of a kind of efficient of earlier 1900s invention that impact rotating creeps into.The essence that impact rotating creeps into method is exactly on the basis of at present general rotary drilling, to add an impactor, impactor is connected on drill bit top, drill bit is in certain axial compression effect turning down, and impactor applies the shock loading in cycle to drill bit, has quickened the fragmentation of rock.The method that impact rotating creeps into can improve rate of penetration, improves the wellhole quality, reduces drilling cost.This method has obtained effect preferably in the drilling well of the hydrology, geology, but still exists the lower problem of impactor working life.In oil drilling, the method that seldom adopts impact rotating to creep into up to the present.Its main cause is that existing impactor is the controlling organization that disposable control guiding valve, plane valve or disposable control plane valve add spring, control vibration cylinder working.Because of spring fatigue or because of a large amount of mud by guiding valve, guiding valve is quick-wearing very.It is very low once to control the impactor life-span, has influenced and has promoted the use of.
Percussing device for percussion revolution drill of the present invention is with the servo fluid control principle, is applied in the impactor; Mainly form, do not have spring in the entire infrastructure by controlling organization, operating valve and vibration cylinder.Controlling organization is twice control.The one, oscillator sends the work of oscillator signal instruction works valve; The 2nd, operating valve control vibration cylinder working.Since the less fluid that controlling organization of fluid ratio that the secondary controlling organization passes through passes through, and it is little to wear and tear; Needed pressure differential is very little during operating valve work simultaneously, works long hours so still can keep after the wearing and tearing.Operating valve is the plane valve, and the impurity sensitivity is little in the valve convection cell of plane, and the life-span is long.So the life-span of Percussing device for percussion revolution drill is longer than the present impactor life-span.Can be applied in the oil drilling that flushing liquor is a mud.Will obtain more significant effect if be applied in the probings such as the hydrology, geology.
Percussing device for percussion revolution drill operating principle: see accompanying drawing 1
When the fluid with certain pressure flows into impactor, be divided into two the tunnel, the one tunnel and feed oscillator (2), the one tunnel leads to signal distributor (3) and operating valve (6).Fluid vibrates oscillator by behind the oscillator (2), and signal distributor (3) is pressed the oscillator frequency of oscillation with the fluid of passage (1) and distributed, instruction works valve (6) work.The duty of vibration cylinder is described below in two steps:
(a) is that oscillator (2), signal distributor (3) send instruction in the accompanying drawing 1, passage (4) is a high-pressure fluid, passage (5) is a low-pressure fluid, operating valve (6) present position makes the fluid of passage (1) enter the epicoele of vibration cylinder (7) piston, and the cavity of resorption fluid of vibration cylinder (7) piston flows to outside the impactor shell through operating valve (6).The piston of vibration cylinder (7) drives block stamp (8) and moves downward, and finishes the one-shot to drill bit.
(b) shifts one's position for oscillator (2) in the accompanying drawing 1, signal distributor (3) sends instruction, passage (5) is a high-pressure fluid, passage (4) is a low-pressure fluid, the valve (6) that pushes the work forward commutation, the position of operating valve (6) makes the fluid of passage (1) enter the cavity of resorption of vibration cylinder (7) piston, and the fluid of vibration cylinder (7) piston upper chamber flows to outside the impactor shell through operating valve (6).The piston of vibration cylinder (7) drives block stamp (8) and moves upward, and performs to impact next time to prepare.
Because continuously when having the fluid of certain pressure, self promptly produces continuous oscillation to oscillator (2), signal distributor (3) is instruction works valve (6) continuous operation, and the piston of vibration cylinder (7) promptly drives block stamp (8) and produces continuously and impact.
This kind control produces oscillator signal through oscillator (2) earlier, controls vibration cylinder (7) work through signal generator (3) instruction works valve (6) work again, so claim " secondary control ".
