Abstract

A propulsion generator which employs one or more unbalanced rotors, such as fly wheels or other unbalance rotating members, which can be connected at a lower portion of a downhole coiled tubing string or other downhole tubular string for inducing propulsion of the coiled tubing. The unbalanced rotors may be oriented at different positions with respect to each other. The instantaneous fluid flow through the propulsion generator is substantially equivalent to the average fluid flow rate through the tool to provide relatively consistent fluid flow to downhole motors below the propulsion generator for operating the drill bit and/or cutters.
