Ultrasonic/sonic mechanism of deep drilling (USMOD)
The present invention provides an ultrasonic and sonic mechanism of deep drilling (USMOD) that is driven by a vibrating actuator and operates in a similar manner to the gopher with regards to drilling debris removal. The actuator induces vibration in the form of a hammering actuation. The mechanism consists of a penetration bit with a diameter that is the same or larger than the actuator. The embodiment of the invention that is disclosed herein emulates a gopher. This ultrasonic gopher is lowered down into the produced borehole, cores the medium, breaks and holds the core, and finally extracts and deploys the core.A USMOD device consists of power drive and a drill-head. The power driver generates ultrasonic pulses to activate the USMOD mechanism and it allows optimized use of power by duty cycling the signal. The drill-head consists of an actuator, free mass and a penetration bit. The actuator consists of a vibration source and a horn that amplifies the amplitude of the vibration. The horn has a cylindrical cross-section to produce a drill-head that has cylindrical configuration and eliminate undesirable trapping of extracted soil and powdered cuttings. A cavity inside the tubular-shape horn provides space for packaging miniature instrumentation and sensors. The actuator activates an integrated free-mass that hammers the penetration bit, where the free-mass operates as a transformer to lower the vibration frequency to produce the hammering action. In one implementation of the USMOD it is designed to contain a trap for collection of upward traveling dust, debris and powdered cuttings.
