摘要： A system and method for emplacing a relatively large casing under and spanning an obstacle such as a river is disclosed. A liquid-occupied passageway is excavated along an arcuate path beneath the obstacle between positions at or near ground level on either side. A casing of lesser diameter than the passageway is introduced into the passageway following the excavating apparatus. A transport fluid is introduced at the excavating site to entrain the cuttings resulting from the excavating. The casing is non-rotatably advanced along the arcuate path of the passageway, and the transport fluid and entrained cuttings are collected in the interior of the leading end of the casing. The transport fluid and entrained cuttings are evacuated under positive pressure from the interior of the leading portion of the casing to prevent the cuttings from settling in the ground circumscribing the advancing casing. The interior of the casing is sealed off proximate the leading portion thereof to provide buoyancy to the casing in the passageway. The casing is weighted to substantially neutralize the buoyancy of the casing and thereby minimize friction between the casing and the sidewalls of the passageway to facilitate advancement of the casing into the passageway.

摘要： Apparatus is provided for installing a pipeline in borehole comprising a pulling pipe drawn by a drill string and an articulating joint coupling the pulling pipe to the pipeline. The articulating joint allows an angle to be formed between the pulling pipe and the pipeline. A reamer is used to clear the borehole as the pipeline is installed. The reamer includes a plurality of radially-oriented nozzles for directing fluid away from the stem of the reamer in order to clean the teeth of the reamer without directing the cuttings and other debris toward areas in which accumulation is likely to occur. Deflecting nozzles prevent the outermost radially-oriented nozzles from overcutting the borehole.

摘要： A method and apparatus for removing drilling mud within entrained cuttings is provided using a pump for forcing fluid into a borehole, such that the fluid mixes with cuttings formed during the formation of the hole. The pipe receives the fluid and entrained cuttings at a first end of the pipe and returns the fluid and entrained cuttings to the surface at the second end of the pipe. At the first end of the pipe, air is injected into the drilling fluid with entrained cuttings to form bubbles therein, thereby increasing the velocity of the fluid and entrained cuttings through the pipe. In one alternative embodiment, a suction is provided at one end of the pipe to increase the speed of fluid and entrained cuttings therethrough. In a third embodiment of the present invention, an Archimedes screw is used to remove the fluid and entrained cuttings from the borehole.

摘要： A method and apparatus for enlarging an inverted arcuate underground path between two surface locations is disclosed, where the cuttings from the enlarging are removed. After the drilling of a pilot borehole, and possibly after some reaming operations, a reamer and hole cleaner are pulled through the path, with the reamer rotating as the drill string in the path rotates. The rotation of the drill string also powers a positive displacement pump inside of the hole cleaner, which pumps fluid and entrained cuttings to the surface behind the hole cleaner. Fluid may also be pumped into the reamer from behind the hole cleaner, preferably by way of an inlet pipe which surrounds the outlet from the pump. The hole cleaner includes an agitator, also powered by the rotation of the drill string, which agitates the fluid and cuttings while the drill string is rotated but is not being pulled to the surface. Pressure control may be maintained either by monitoring the fluid in and out of the path together with the volume of the cuttings, or by direct monitoring of the pressure at the reamer.

摘要： An apparatus and method for drilling a pilot bore hole (B) along an underground arcuate path (P) between two surface locations (O, E). The pilot bore hole (B) is drilled in one direction with a drill string (10) having a leading pipe section (10A) of a reduced diameter to provide increased flexibility. Upon completion of the pilot bore hole (B), a reamer (48) connected to a product conduit (46) is connected to the drill string (10). Drill string (10) pulls the reamer (48) and product conduit (46) along the pilot bore hole (B) in an opposite direction for enlarging the bore hole (B) to receive the product conduit (46). A spud bit (34) has a flat or blunt leading end portion (34A) with a discharge opening (34D) therein to discharge high velocity drilling fluid into the formation at a location offset from the longitudinal axis of the drill string (10) to assist in guiding the drill string (10). An in-hole hydraulic motor (70) is provided in an embodiment (FIG. 7) for rotating the drill bit (78), and the longitudinal axis of a drive shaft (74) for the drill bit (78) is offset from the longitudinal axis of the drill pipe string (10) to assist in a deviation of the drill bit (78).

摘要： A directional drill bit utilizing pressurized fluid as a means for eroding earth in a forward path of the bit and being used to drill at least a portion of an arcuate path, comprises an elongate hollow body having two sections joined one to the other by a flexible joint, a box end connection, a jet nozzle, an articulation device comprising a spring and a stop, the articulation device being responsive to changes in fluid pressure by permitting a forward portion of the bit bearing the nozzle structure to change angular position with respect to an aft portion of the bit, by the forward portion moving from a first position relative to the aft portion to a second position relative to the aft portion. The spring is positioned in a manner which defines an initial, pre-selected degree of axial alignment describing a first angle formed by the relative position of the longitudinal axis of the first section with the longitudinal axis of the second section when the elongate hollow body is in its "at rest" position, that is, when no fluid is flowing through the drill bit. The stop is positioned in a manner which defines a final, preselected degree of axial alignment describing a second angle formed by the relative position of the longitudinal axis of the first section with the longitudinal axis of the second section when the elongate hollow body is in its maximum degree of angular displacement relative to the initial, pre-selected degree of axial alignment.

摘要： A directional drill attached to a drill string having periodic concentric collars is advanced in an inverted arcuate path to form a pilot hole underneath an obstacle followed by a larger concentric washover pipe. When the washover pipe reaches the surface on the other side of the obstacle a first reamer is attached to the end of the washover pipe exiting the drilling path, a second reamer of smaller diameter than the first reamer is attached to the other end of the first reamer by means providing for some separation between the two reamers, and a production casing of smaller diameter than the second reamer is attached to the other end of the second reamer with a swivel. The remaining length of the first portion of casing is supported some distance above the ground on rollers located above and beyond the exit point of the pilot hole. The reamers are operated by rotating the washover pipe and simultaneously drawing the washover pipe through the pilot hole. As the reamers are drawn through the pilot hole the first reamer enlarges the hole to a diameter greater than that of the casing. Drilling mud pumped through the washover pipe exits at the reamers to entrain the dislodged earth and the second reamer compacts it to form a bushing around the sides of the enlarged hole to lubricate the passage of the casing. The reaming operation may be performed without the production casing attached to the reamers followed by a second reaming operation with the casing attached in order to complete the installation.

摘要： A method and apparatus is disclosed for installing a large diameter pipe--in the range of 30 inches diameter--for spanning an obstacle, such as a river, along an invert arcuate underground path. An inclined drill rig, having a mud supply system and power pod, includes an angularly inclined ramp and driven car for crowding, without rotation, a pipe either pre-bent to a preselected and constant radius of curvature or a straight pipe into the ground. The pipe at its head includes an articulated drill head, which by appropriate articulation, assures placement of the pipe along a radius of curvature equal to the pre-bent radius of curvature of the pipe. The articulated drilling head includes a hydraulic system for articulating and driving the cutting head and pumping mud and tailing from the pipe path. Two discrete mud systems are used. The first mud system is utilized to entrain and carry away cuttings. The second mud system is combined with a flared skirt about the point of drill head articulation to provide a clean and high lubricity annulus of mud about the advancing drill string. The density of the first mud system can be used to vary the drill string mass, while the density of this second mud system can be used to vary the density of the fluid in which the drill string is buoyantly supported.
