Downhole mobility and propulsion apparatus |
摘要 |
An apparatus which comprises an upper sub for connectable engagement with the wire line, a microprocessor component for directing the various functions of the overall apparatus down hole; a motor section having a plurality of thrust directional motors and ball screw assembly for movement of steering gates; a motor driven impellar means for providing thrust and flow through a portion of the apparatus and in combination with the flow gates providing steering in a certain direction; an electric transducer portion for providing ultrasonic vibrations around the circumference of the apparatus in discongealing molecular substrate adjacent the apparatus; a mechanical vibration coil assembly means on the lower end of the apparatus for discongealing larger areas of congealing in a substrate around the apparatus, and a lower sub for connectably engaging the electrical logging unit to be steered down hole. The apparatus may also comprise on either end a thrust explosive sub for explosively dislodging the apparatus in the event of lodging occuring down hole.
