Drilling apparatus comprises a hollow drill pipe (2) extending through a drill hole (4) to a mud motor (8). The motor (8) drives a compressor (12) through a shaft (14). An annular passageway (16) around the compressor (12) leads to a drill bit (18) having nozzles (20) providing an outlet from the passageway (16). A housing (22) of the compressor (12) provides a passageway (24) for leading fluid through the compressor (12) to emerge through nozzles (26) in the drill bit (18) at increased pressure to assist the drill bit (18). |

| 104 | Intermittently rotating drilling tool | EP84300227 | 1984-01-13 | EP0149290A3 | 1985-10-09 | Walter, Bruno Hartwig |
In an intermittently rotating down-hole drilling tool a closed valve (17) is operatively moved downwards by pressurised drilling mud pumped down the drill string (11), the valve when it attains its lower position being opened and being returned under the influence of a spring (40) or other upward urging means acting on the valve to its upper position at which the valve is closed, thereby completing the cycle of operations. The valve is continuously coupled to a torque member (71) such that the downward movement of the valve causes the torque member to turn in one direction, and the upward movement of the valve causes the torque member to turn in the opposite direction. A drill bit (103) mounted on the lower end of a rotor (75) is connected, by means of a one-way clutch (76). to the torque member so that during the downward movement of the valve the rotor and drill bit are rotatably driven by the torque member but are stationary during the upward movement of the valve the drill bit thus being operatively intermittently rotated. During the upward movement of the valve the pressurised drilling mud flows through the open valve and issues from the drill bit as high pressure and volume flushing jets while the drill bit is stationary, thereby providing a more effective cleaning of cuttings and chips from the bottom of the bore hole being formed by the drill bit. Aligned annular grooves (87, 88) are provided in the rotor and in the housing in which the rotor is mounted, ball bearings (89) being partially disposed in each of these grooves, thereby to provide an axial thrust bearing (86) capable of transmitting high axial thrust from the housing to the rotor and hence to the drill bit. Lipped pockets (90) are also provided in the rotor in communication with the grooves therein, with the ball bearings being disposed within these pockets during assembly and disassembly of the rotor and housing. |

| Procédé et appareil de perforation de trous profonds dans la roche ou autre. L'appareil est adapté pour être fixé à l'extrémité d'un cordon de forage (1) et être descendu au fond d'un trou de forage (27). L'appareil comprend une unité de commande pilote (D), un moteur hydraulique (12), une pompe hydraulique (16), un appareil à percussion (21) et un trépan de forage (23). La boue de forage qui est descendue au travers du cordon de forage pour innonder et remonter les débris séparés entraîne le moteur hydraulique qui est d'une construction robuste et supportera les effets de la boue de forage abrasive. L'arbre de sortie (15) du moteur entraîne la pompe hydraulique qui pompe du fluide hydraulique d'un grade élevé jusqu'à l'appareil à percussion qui est un marteau perforateur entraîné hydrauliquement, de construction connue. Le piston de percussion frappe contre le trépan. L'appareil entier est en rotation à l'aide d'une machine rotative placée sur le niveau du sol. Grâce à l'unité de commande pilote (B), l'appareil n'a qu'à porter son propre poids mort et des ouvertures et des soupapes assurent une dérivation et un arrêt, respectivement, pour la boue de forage. | ||||||

Die Erfindung betrifft eine Vorrichtung zur Gewinnung von Mineralien durch ein Bohrloch, welche Vorrichtung im wesentlichen aus an einem Bohrgestänge befestigten und gegenseitig gelenkig verbundenen Schüssen (8, 9, 10) besteht, die in gestrecktem Zustand in das bereits im mineralen Gestein niedergebrachte Bohrloch eingebracht werden können und aus Mitteln, mit deren Hilfe die Schüsse anschließend in Zick-Zack-Position gebracht und in axialem Sinne hin- und herbewegt werden, während es an den Gelenkverbindungen der Schüsse Mittel gibt, die das Mineral außerhalb der Bohrlochwandung auflockern und mit Hilfe von Dickspülung durch dieselbe Lochbohrung abführen. Die vorliegende Erfindung kennzeichnet sich besonders dadurch, daß sich die gegenseitig gelenkig verbundenen Schüsse in gestrecktem Zustand in einer in das Bohrloch hineinpassenden Hülse (5) befinden, welche einen oder mehr Längsschlitze (6, 7) aufweist, durch die die Schüsse aus der Hülse hinausragen können, wobei sie durch mit der Hülse zusammenwirkende Mittel, die eine axiale Kraft auf die äußeren Schüsse ausüben können, umgeknickt werden. Die axiale Bewegung der Vorrichtung kann durch einen hydraulischen Druckzylinder (1,48, 50) in der Nähe der Hülse hervorgerufen werden. |

| Methods and apparatus are disclosed to overcome problem that are encountered when using coiled-tubing to deploy radial drilling tools in certain wells. In addition, this disclosure provides means and tools by which radial drilling tools can be conveyed and powered by slickline or e-line. To advance the radial drilling tools and/or to apply and control weight on bit (WOB), a chamber is created and is then pressurized to generate a piston-affect. Furthermore, tools and methods are provided to monitor the radial drilling tools' operations and to convey this information to surface personnel. In addition, because the e-line, slickline and certain coiled-tubing strings lack adequate torsional stiffness, torque arresting mechanisms are disclosed. This disclosure further provides for a “zero-discharge drilling” system, a “drill-by-wire” system, and enables radial drilling solutions in horizontal wells using coiled-tubing, e-line or slickline. | ||||||
