摘要： Vibrational apparatus to direct stress waves (eg. to a bit 2 or other downhole tool) by generating vibrations as a consequence of shuttling responsive to relative rotational movement between magnetic arrays (4,5) and wherein there is, or can be, a use of a system (6,7) (whether rebound, recoil, spring, pneumatic, magnetic or not) able at least in part to return acquired potential energy in addition to any acquired at the same time by the interacting magnetic arrays. A free travel distance can be provided for one of said components prior to the onset of any substantial collection of energy from the movement (relative) of that component in a direction (eg, uphole) for use in return travel (eg, downhole) preferably synchronized, or synchronizable, to enhance the return travel causing forces of any repulsive and/or attractive forces generated otherwise than by the said magnetic arrays.

摘要： The present invention concerns a down-the-hole drill that is driven via a drill string by a flow of fluid. It comprises a housing with an impact mechanism, a drill bit that is mounted such that it can be axially displaced in a driver chuck that is mounted in bearings in the housing such that it can be rotated, the impact mechanism being arranged with a hammer piston with a piston surface arranged to impact onto a neck at the drill bit, and a valve to control the hammer piston backwards and forwards between an initial position and an end position, whereby the valve of the hammer piston alternately places under pressure and removes the pressure from a pressure chamber that drives the hammer piston forwards when placed under pressure, the housing further comprising a fluid-driven rotation motor of vane motor type comprising pressure chambers with vanes that rotate the drill bit when placed under pressure. A flow pathway for the flow to the pressure chambers of the rotation motor is opened by the valve of the hammer piston when the valve closes the flow pathway to the pressure chambers of the hammer piston.

摘要： A percussive hammering assembly comprises a tool assembly (24, 25). The tool assembly (24, 25) is arranged to be oscillated in a direction (P) within a casing. An impact piston (27) is arranged slideably in a housing (28), together with a control valve (29) forming an impact assembly. An optional rotation module (37) is connected to the tool assembly (24, 25) to index the tool head (24) in contact with material to be removed. A drive assembly comprises a hydraulic pump (35) and a drive means (36), supplying pressure to a closed- loop hydraulic circuit. Constant liquid volume accumulators (30a, 30b) are arranged between a high pressure line (HP) and low pressure line (LP) within the closed-loop hydraulic circuit. A differential pressure compensator (38) is arranged between the LP line of the closed-loop hydraulic circuit and environmental pressure. The respective components are all accommodated within a liquid- filled casing.

摘要： In a liquid downhole drilling machine, the guiding bushing (31) for the drill bit is rotatably journaled in the housing (11, 12) and, via a one-way coupling (29), coupled to a turning sleeve (22) that has axial ridges (24) that bound a number of chambers (25, 26, 27) and form turning pistons for turning the turnable sleeve to and fro. A number of these chambers are coupled to be pressurised and depressurised simultaneously with said pressure chamber (47) with the piston area (46) for urging the piston hammer (30) forwards. As a result, the drill bit (13) will be indexed a defined angle between each impact so that the button inserts of the drill bit will change contact points with the rock between every impact and fragment the rock efficiently. The drill tube is not rotated.

摘要： A hybrid bit includes an earth-boring element and a percussion element. The earth-boring element and the percussion element are coaxially arranged, with the earth-boring element surrounding the percussion element. A reciprocating member of the percussion element may oscillate in a manner that enables a bottom end of the reciprocating member to repeatedly protrude from a bottom end of the earth-boring element and to be repeatedly withdrawn. A configuration of the earth-boring element may enable it to drill into and remove some materials from an earth formation, while the percussion element may enable the hybrid bit to drill into and remove difficult-to-drill materials, including abrasive materials with high compressive forces, such as chert.
