Abstract: Downhole drilling often requires passing drilling fluid containing water mixed with mud through a downhole drill pipe. Such drill pipe may comprise cavities therein for working units such as motors, generators, solenoids and the like. It may be desirable to lubricate and cool such working units with water from the drilling fluid, however, mud particulate may damage such devices. The present invention comprises various embodiments of a dynamic seal assembly designed to allow fluid communication between a cavity and a fluid flow while blocking certain particulate matter within the fluid flow from entering the cavity. The fluid communication may occur through and the particulate matter may be blocked by a defined clearance between two complementary surfaces that are movable relative to each other.

Abstract: A hammer assembly comprises a jack element substantially coaxial with an axis of rotation of a drill bit. The jack element includes a distal end extending beyond a working face of the drill bit. A porting mechanism within the bore comprises a first and second disc substantially contacting along a flat interface that is substantially normal to the axis of rotation. The first disc is attached to a turbine which is adapted to rotate the first disc with respect to the second disc. The first disc comprises a first set of ports adapted to align and misalign with a second and third set of ports in the second disc. As the first disc rotates, the sets of ports are adapted to route a drilling fluid into a piston chamber where a porting mechanism causes the jack element to repeatedly extend further beyond the working surface of the drill bit and then retract at a constant frequency.

Abstract: In one aspect of the present invention, a drill bit has a jack element that is substantially coaxial with an axis of rotation of the drill bit and the jack element has an asymmetrical distal end that extends beyond a working face of the drill bit. A turbine is located within a bore formed in the drill bit and a flow valve is actuated by the turbine. The flow valve is adapted to route a drilling fluid in the bore into a porting mechanism adapted to extend the jack element farther beyond the working surface of the drill bit. The turbine is also adapted to rotate the jack element at variable speeds.
