    摘要: A laser-jet apparatus for creating a penetration through a stress region adjacent to a wellbore includes an outer tool housing, the outer tool housing having a housing central bore. A laser assembly includes a lens case with an outer diameter that is smaller than an inner diameter of the housing central bore, defining an annular passage between the outer tool housing and the lens case. A focusing lens and a collimating lens are located within the lens case. The focusing lens is shaped to control the divergence of a laser beam and the collimating lens is shaped to fix the diameter of the laser beam. A jet fluid path is located in the annular passage, the jet fluid path shaped to merge jet fluid with the laser beam. The outer tool housing has a frusto-conical tip for directing the combined jet fluid and laser beam to the stress region.

    摘要: The invention is related to a system which has been developed to obtain gas from the gas hydrate formations that are found under the frozen layers of earth in the cold regions or sea floor/slopes and comprises a drilling machine (3) that performs drilling by means of a drilling bit (33) after being lowered into the drilled well, drilling machine lowering and controlling equipment (1) which allow said drilling machine (3) to be lowered into the well and supply power and control to the system (A), and a stripped production tubing (4) with plugs (41) in which the water level and water level dependent pressure and gas pressure are controlled, which allows for the dissociation of the formation into gas and water and forming a cavern (6), and in which the gas separated from the gas hydrate formation reaches the surface; and to the method presented by using said system (A).

    摘要: A ground drill system (10) has a drill string 14 which forms first and second mutually isolated fluid paths (16 and 18) respectively. The drill string (14) has an up hole end (20) coupled to a dual circulation rotation head (22) and a down hole end (24) which is coupled to a drilling tool (12). The drilling tool (12) is operated by the flow of fluid delivered through the first flow path (16). A second fluid outlet (26) is provided intermediate the up hole end (20) and the drilling tool (12). The outlet (26) is in fluid communication with the second fluid flow path (18) and located a constant or fixed distance from the drilling toll (2). The second fluid outlet (26) discharges a flushing fluid flowing through the flushing flow path (18) into a hole being drilled by the drilling system (10). The rotation head (22) provides torque to the drill string (14) and thus the drilling tool (12).

    摘要: A method and apparatus for completing a lateral channel in a subterranean formation using a flexible hose with a waterjet that may be directed down a well casing and into a waterjet guide. The waterjet guide has a diverter assembly configured to receive and divert the flexible hose in a shortened radius. The diverter assembly includes an inlet curvature and a pivot curvature, where the pivot curvature pivots between stowed and deployed configurations in response to forces provided through a mandrel assembly communicably coupled thereto.
