    摘要： A method and system for excavating a subterranean formation using a fluid comprising pumping the fluid through at least one nozzle such that a velocity of the fluid when exiting the nozzle is greater than a velocity of the fluid entering the nozzle. A plurality of solid material impactors are introduced into the fluid and circulated with the fluid through the nozzle. A substantial portion by weight of the solid material impactors has a mean diameter of equal to or less than approximately 0.100 inches. The fluid is pumped at a pressure level and a flow rate level sufficient to satisfy an impactor mass-velocity relationship wherein a substantial portion by weight of the solid material impactors has a minimum kinetic energy of approximately 0.075 Ft Lbs when exiting the nozzle. The substantial portion by weight of solid material impactors exit the nozzle and contact the formation.

    摘要： A jet cutting device comprising a cutter head provided with at least one nozzle for ejecting a stream of fluid against a body so as to create a selected cut in said body, is discloded. For each nozzle, the cutter head is provided with a deflector having a deflection surface arranged to deflect the stream of fluid ejected by the nozzle into a selected direction in accordance with the position of said cut to be created.

    摘要： A fluid drilling head has a plurality of nozzles (3, 4, 5, 6) in a rotatable nozzle assembly (2) to provide high pressure cutting jets (7). The head is provided with a gauging ring (10) having an annular clearance (11) to the rotatable nozzle assembly (2) to provide for the passage of rock particles eroded by the cutting action of the jets (7) while regulating the progress of the drilling head in the borehole and controlling drill stalling. A stepped rotatable nozzle assembly having a smaller diameter portion (8) and a larger diameter portion (9) to extend the cutting zone of a reaming jet closer to the outer diameter of the gauging ring(10) is also described and claimed.

    摘要： A drilling assembly for drilling a borehole into an earth formation is provided, comprising drill string extending into the borehole and a jetting device arranged at a lower part of the drill string, the jetting device being provided with a mixing chamber having a first inlet in fluid communication with a drilling fluid supply conduit, a second inlet for abrasive particles and an outlet which is in fluid communication with a jetting nozzle arranged to jet a stream of abrasive particles and drilling fluid against at least one of the borehole bottom and the borehole wall. The jetting device is further provided with an abrasive particles recirculation system for separating the abrasive particles from the drilling fluid at a selected location where the stream flows from said at least one of the borehole bottom and the borehole wall towards the upper end of the borehole and for supplying the separated abrasive particles to the second inlet.

    摘要： Ein Verfahren zum grabenlosen Leitungsaustausch umfaßt für jede zu sanierende Abschnittslänge die Schritte des Vorantreibens mehrerer verlaufsgesteuerter Bohrungen (18) entlang und nahe des Umfangs der auszutauschenden Leitung (60) bis zu einer Zielgrube (52) hin, das drehstarre Anbringen des Spülkopfes (20) am Bohrgestänge (56) in der Zielgrube (52) und das Zurückziehen des Spülkopfes unter gleichzeitigem Austritt von Spülflüssigkeit bis zu einer Startgrube (50). Anschließend wird die auszutauschende Leitung (60) aus dem Erdkanal herausgezogen und der Erdkanal mit einem Stabilisiermittel verfüllt. Abschließend wird eine neue Leitung (66) eingezogen. Der zur Verwendung gelangende Spülkopf umfaßt eine Anbringeeinrichtung (28) zur drehstarren Befestigung an einem Bohrgestänge, das eine Zugrichtung in Längsrichtung des Bohrgestänges definiert sowie mehrere Austrittsdüsen (24) für Spülflüssigkeit am Spülkopf. Der Spülkopf kann entweder eine im wesentlichen einem Kreissegment entsprechende Querschnittsform senkrecht der Zugrichtung besitzen oder aber im wesentlichen zylinderförmig ausgebildet sein, wobei die Austrittsdüsen im Zylindermantel des Spülkopfes angeordnet sind.
