Abstract
Abstract A drilling system is disclosed which relies on the weight and reciprocating movement of the drill column to provide actuation and rotation of the drill bit at the bottom of the bore hole. A pneumatic power source located immediately above the bit is driven by raising the suspended drill column by means of draw works and releasing the column to convert the kinematic motion of the column into fluid power in the pneumatic power source. The compressed fluid enters a pneumatic chamber and causes rotation of the drill bit as it engages the sides and bottom of the bore hole. The system may also include a source of drilling fluid pumped from the surface through the drill column and pneumatic power source to the bottom of the well bore to return the cuttings to the surface. The pneumatic fluid after it drives the bit and is expanded may be mixed with the drilling fluid to provide a lift assist to the fluid as it is returned to the surface with the drill cuttings.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
68 words
A fluidic-kinetic drilling system comprising in combination: a downhole assembly comprising: a rotatable drilling bit; fluidic means for rotating the drilling bit; a fluidic power source means responsive to kinetic reciprocation for actuating the fluidic means; suspending means extending from the surface for suspending the downhole assembly adjacent the bottom of a bore hole; and means connected to the suspending means for reciprocating the fluidic power source means.
Claim 2
Dependent Claim
68 words
A fluidic-kinetic drilling system comprising in combination: a downhole assembly comprising: a rotatable drilling bit; fluidic means for rotating the drilling bit; a fluidic power source means responsive to kinetic reciprocation for actuating the fluidic means; suspending means extending from the surface for suspending the downhole assembly adjacent the bottom of a bore hole; and means connected to the suspending means for reciprocating the fluidic power source means.
Claim 3
Dependent Claim
17 words

Claim 4
Dependent Claim
26 words
A system according to claim 1 further including fluid supply means extending from the surface to the fluidic power source means for delivering power fluid thereto.
Claim 5
Dependent Claim
33 words
A system according to claim 3 in which the suspending means comprises a series of connected pipe sections forming a drill column and said fluid supply means is received within said drill column.
Claim 6
Dependent Claim
28 words

Claim 13
Dependent Claim
28 words
A system according to claim 11 further including means for expelling the exhaust gas from the pneumatic rotor into the rising drilling mud to assist the lift thereof.
Claim 14
Dependent Claim
18 words
A system according to claim 3 in which the fluidic power source means includes a fluid compression chamber.
Claim 15
Dependent Claim
18 words
A system according to claim 13 in which said compression chamber includes a piston chamber and a piston.
Claim 16
Dependent Claim
30 words
