Dynamic auxiliary rock crushing tool.
Background technology
Drilling well is by setting up the process that pit shaft connects ground and earth formation deep.During drill bit is drilling process
Most important rock crushing tool.When bore meet hard formation when, the ability of drill bit fractured rock will have a greatly reduced quality, rate of penetration therefore significantly
Reduction, may be per hour down to by tens of rice one meter it is even lower per hour.To improve rate of penetration, especially bore and meet hard formation
When rate of penetration, in recent years, researcher according to the physical principle of resonance propose by produce resonant frequency induce rock
Stone partial crushing, so that drill bit broken rock is aided in, the method for improving rate of penetration.
Resonant frequency refers to a physical system under specific frequency, the feelings vibrated than other frequencies with bigger amplitude
Shape, these specific frequencies are referred to as resonant frequency.Under the frequency, the Periodic signal drive power of very little just can be produced significantly shakes very much
It is dynamic.A usual system has multiple resonant frequencies, and vibration on these frequencies is easier, and is vibrated and is compared in other frequencies
It is difficult.If system is acted on by complex vibration, its resonant frequency can be typically selected to be vibrated with this frequency, as by other frequencies
Filter out general.
Aberdeen of Britain proposes to resonate breaking technique for rock for 1998 for oil drilling, and through persistently studying for many years,
Form the resonance rock crushing tool model machine using piezoelectric as vibration source.The model machine is equipped with the drill bit of special development.It is indoor real
When this real set model machine of checking is crept into hard formation, rate of penetration is greatly improved compared with conventional tool.
U.S. NASA propeller research institute proposes that a kind of ultrasonic vibration aids in the instrument of coring, i.e. coring bit to rotate
When, while the dither triggered by piezoelectric, rock is acted on by rotational shear and high-frequency percussion simultaneously, crush
Faster.When making coring in this way, the power of consumption is less, and the bit operation life-span is longer, and need not use drilling fluid.
Domestic BJ University of Aeronautics ＆ Astronautics, Shenyang automation research institute have carried out Primary Study with regard to vibration broken rock drill bit,
Ultra micro vibration broken rock drill bit has been manufactured experimently by core devices of piezoelectric.Its principle is that occur height using ultrasonic exciting ultrasonic transformer
Frequency vibration, the vibration passes through the mass being connected with ultrasonic transformer and further amplified, and the vibration after amplification is delivered on drill bit, and drill bit is high
Frequency impact rock, so as to form hole.
Integrate apparently, research both domestic and external at present is concentrated on produces high frequency axial vibration by piezoelectric, and will vibrate
It is delivered on drill bit, drill bit is occurred axial vibration, this vibration is ultimately applied to rock, so as to improve rock breaking efficiency.
Because conventional PDC drill bit cutting tooth is diamond compact, quality is firmly crisp, is generally difficult to bear the axial direction punching of high frequency
Hit；Other piezoelectric own temperature during continuous dilatation will be raised drastically, can reach in the short time 200 or
300 DEG C, it should not be used in conjunction with conventional downhole tool.
Thus, the present inventor relies on experience and the practice for being engaged in relevant industries for many years, proposes that a kind of twisting vibration auxiliary is broken
Rock instrument, to overcome the defect of prior art.
