摘要： An underreamer which may be mounted on a core drill to allow single phase underreaming or creation of a bore hole of larger diameter beneath a pilot hole. A plurality of levers are powered by a plurality of corresponding jacks which are adapted to exert pressure on the levers in order to cause them to extend beyond the periphery of the expander body. Each lever contains at least one roller-cutter rotatably mounted to the lever so that when the levers are forced outward, the roller-cutters crush rock beyond the periphery of the expander body and thus underream the bore hole.

摘要： The well reamer comprises a sub for attaching it to the drive means, a hollow housing with a central channel and radial openings in its side wall, projectable rolling cutters with shanks, mounted in the radial openings of the housing, and a mechanism for projecting the rolling cutters, including a piston and a member for locking the rolling cutters in their operating positions. The annular piston is connected with the housing for joint rotation therewith, and is regidly connected with the sub. The wall of the piston has radial passages made therein, establishing communication between its central channel and so annular space defined between the walls of the piston and of the housing. The member for locking the rolling cutters is accommodated with a clearance in the central channels of the piston and of the housing, and has an annular shoulder. The central channel of the piston defines a seat for engagement with the annular shoulder of the locking member.

摘要： A well bore is formed which runs down to an underground region having deposits of mineral material to be mined, by installing a casing or a drill pipe into the ground. A piping assembly is placed in the bore hole through the casing and the mineral material comminuted by means of water jet action or by vibratory action of a portion of the piping thereagainst or by both types of action operating simultaneously. The mineral material is mixed with the water in the bore hole to form a slurry which is removed from the bore hole through the piping by sonic pumping action or by virtue of the slurry rising to the surface as the bore hole fills, with oil floating to the top of the slurry material.

摘要： A rotary bore hole enlarging bit is connected to a rotary pipe string having a drilling fluid flow path and an actuator flow path. The bit comprises a body structure including inner and outer telescopic body sections, expansible and retractible arms carrying cutters on the outer body section and an expander on the inner body section engageable with the arms to expand the arms and cutters upon telescopic movement of body sections in one relative direction. A piston and cylinder is provided between the inner and outer body sections to secure relative telescopic movement between the body sections. A first passage is disposed in the body structure and expansible arms and cutters for conducting drilling fluid to the cutters from the drilling fluid flow path, there being a second passage in the body structure for conducting actuator fluid to the piston and cylinder from the actuator fluid flow path.

摘要： A raise boring system is provided for boring raise holes wherein the finished raise holes have portions of different diameters. The system includes a raise head with a central drive stem defining an axis of rotation. Primary cutter means are positioned on the raise head for disintegrating the earth formations out to a first radial distance from said axis of rotation. Expanding secondary cutter means are positioned on the raise head for selectively disintegrating earth formations from said first radial distance out to additional and greater radial distances from said axis of rotation. The expanding secondary cutter means may be selectively located in a first position either beneath or in the same plane as the primary cutter means during boring at said first radial distance from said axis of rotation and selectively located in additional positions for boring at greater radial distances from said axis of rotation. Expansion means are provided for moving said expanding secondary cutter means to said additional positions during the boring operation.

摘要： An underreamer for enlarging a well bore wherein a plurality of cutter cones are rotatably supported on pivoted cutter arms which pivot outwardly from the body of the tool in response to fluid pressure. The amount of outward pivotal movement is adjustable without the removal and replacement of the cutter arms. This permits the same tool body and pivotable arms to be used for bore enlargements to different diameters relative to the contracted diameter of the tool.
