Abstract
Abstract 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 impeller 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 electrical 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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
142 words
A downhole steering and propelling tool, comprising: a. a tool body; b. steering and propelling means mounted within said tool body, including a plurality of gate members movable between open and closed positions, said gate members in the open position allowing fluid flow through a portion of said tool body; c. vibrator means mounted within said tool body, comprising a mechanical vibrator imparting movements to at least a portion of said tool body for turbulating the medium around at least a portion of the exterior of said tool body; d. explosive means mounted at either end of said tool body, said explosive means including at least a pair of explosive charges housed within said explosive means; and e. electric transducer means contained within a portion of said tool body for providing ultrasonic waves exterior to said tool body upon a pre-determined signal.
Claim 2
Dependent Claim
142 words
A downhole steering and propelling tool, comprising: a. a tool body; b. steering and propelling means mounted within said tool body, including a plurality of gate members movable between open and closed positions, said gate members in the open position allowing fluid flow through a portion of said tool body; c. vibrator means mounted within said tool body, comprising a mechanical vibrator imparting movements to at least a portion of said tool body for turbulating the medium around at least a portion of the exterior of said tool body; d. explosive means mounted at either end of said tool body, said explosive means including at least a pair of explosive charges housed within said explosive means; and e. electric transducer means contained within a portion of said tool body for providing ultrasonic waves exterior to said tool body upon a pre-determined signal.
Claim 3
Independent Claim
59 words
An apparatus for steering equipment downhole comprising: a. a tool body; b. steering means contained within said tool body including gate means, movable between upward and downward positions; c. impeller means rotatably mounted within said tool body; and d. means for imparting rotation to said impeller means as said fluid moves within said steering means for steering said tool.
Claim 4
Independent Claim
59 words
An apparatus for steering equipment downhole comprising: a. a tool body; b. steering means contained within said tool body including gate means, movable between upward and downward positions; c. impeller means rotatably mounted within said tool body; and d. means for imparting rotation to said impeller means as said fluid moves within said steering means for steering said tool.
Claim 5
Independent Claim
76 words
An apparatus for steering equipment downhole, comprising: a. a tool body; b. propelling means, contained within said tool body, including an impeller mounted within said propelling means so that rotation of the impeller blade imparts movement to said tool; c. the vibrator means mounted within said tool body; d. means for providing ultrasonic waves exterior to said tool body; and e. means for dislodging said tool in the event said tool should be lodged while downhole.
Claim 6
Independent Claim
76 words
An apparatus for steering equipment downhole, comprising: a. a tool body; b. propelling means, contained within said tool body, including an impeller mounted within said propelling means so that rotation of the impeller blade imparts movement to said tool; c. the vibrator means mounted within said tool body; d. means for providing ultrasonic waves exterior to said tool body; and e. means for dislodging said tool in the event said tool should be lodged while downhole.
Claim 7
Dependent Claim
26 words
The apparatus in claim 3, wherein said propelling means further includes means for allowing fluid flow through said impeller in order to propel the apparatus downhole.
