摘要： In connection with a method and a tool for preparing a well for the production of hydrocarbons, it is aimed at perforating a casing portion (26) and working surrounding sediment (80) in a channel-forming manner. For this purpose the tool comprises a drilling means for drilling transverse holes through the casing wall when the tool (10), which is arranged to be raised/lowered and rotated about its longitudinal axis, shared by the casing (26), is placed in a fixed position within the well, through which transverse hole (40) and into surrounding sediment a jetting hose means (42, 42a) is arranged to jet/dig its way in a channel-forming manner. The drilling and jetting hose means also have inactive stand-by positions protectively retracted within the tool housing (10a), from and into which they may successively be pushed forward into active working positions and again be withdrawn, as a channel (44) is completed in the sediment (80).

摘要： The present invention relates to a drilling device for creating ramifications in a bore hole drilled in unstable rock, wherein said device comprises a pilot drill head (14) whose progression is fully controlled and has a drill rod (4) attached thereto. The pilot drill head comprises an opening (42) on its periphery, a deflection part (50) located within said head as well as outlet openings (34, 36) through which a bore-hole reinforcing suspension is ejected. An inner drill head (44) is capable of longitudinal displacement along the pilot drill head (14) and is deviated by the deflection part (50) from the path (54) of said pilot drill head (14). After the completion of a pilot bore by forwarding the pilot drill head whose progression is fully controlled, a bore-hole reinforcing suspension is ejected from said pilot drill head while the inner drill head passes by the deflection part in the pilot drill head, a ramification bore being thus created by forwarding said inner drill head.

摘要： Hydraulic drilling apparatus and method in which a hole is formed with a series of drilling heads (26) and strings (42) of successively smaller diameter. After each section of the hole is formed, the drill head is withdrawn back through the string, leaving the string in place in the hole as a casing for the well. The next smaller size drill head and string are then introduced through the strings which have already been placed, and the process is repeated until the hole has reached the desired length. The course of the hole can be changed, e.g. from vertical to horizontal, without interruption of the drilling process by selective application of the drilling fluid to the nozzles in the drill head to steer the advancing string. Multiple laterals (53a-53d) are formed by introducing a module (51) having a plurality of extensible drilling tubes (53) with drill heads (56) at the distal ends thereof into the string and applying the pressurized drilling fluid to the module to advance the tube from the string.

摘要： The invention provides a mining tool (30) for mining an underground substantially horizontal seam of material comprising an eductor module (60) and a fluidising module (62). The fluidising module (62) includes a plenum (66) adapted to receive high pressure fluid from a mining string, and one or more fluid jet nozzles (42,43.44) for emitting the high pressure fluid to mobilise material of the seam. The eductor module (60) includes an eductor assembly (69) adapted to recover the mined material to return it as a slurry along the string. In use, the tool is connected to a mining pipe or string (35) extending from the surface to supplying said high pressure fluid to the eductor arrangement and fluidising nozzles. The eductor assembly is positioned toward the proximal side of the tool which is connected to mining pipe (35). The fluidising jet nozzles are positioned more towards the distal end of the tool, such that when in use, eductor recovers the slurry at said proximal position relative to the string. While the mining tool is continuously withdrawn towards the ground surface along the substantially horizontal borehole, high pressure fluid is fed to the tool to fluidise the material in the seam via the fluidising jet nozzles (42,43,44), and recover the material as a slurry via the eductor arrangement positioned "upstream" from the jet nozzles.

摘要： A spallation drill head (100) can include a drill head body (102) having a primary face (104) substantially oriented facing in a primary drilling direction (106) along a longitudinal axis of the drill head body (102). A liquid inlet can be on the drill head body (102). The liquid inlet can be connected or connectable to a liquid supply line (110). An internal liquid connection (112) can be oriented within the drill head body (102) and fluidly connected to the liquid inlet. A plurality of liquid jets (114) can be oriented on the primary face (104) of the drill head (100). The liquid jets (114) can be fed by the liquid inlet through the internal liquid connection (112). A mass flow controller (116) can be associated with the liquid jets (114) to control delivery of liquid by the liquid jet, and flowrates to at least two of the liquid jets (114) can be independently controllable.

摘要： An apparatus for continuously generating and controlling the density of foam has a fluid in-flow manifold in communication with a source of liquid and comprising a pressure sensor. A plurality of branch lines are in fluid communication with the in-flow manifold a foam out-flow manifold. Each branch line has a flow control valve, a Venturi tube and in fluid communication with a throat of each Venturi tube an air induction control valve. The foam out-flow manifold has a pressure sensor. At least one in-flow control valve is disposed between the source and the in-flow manifold and at least one out-flow control valve is in communication with the out-flow manifold. The branch valves, air valves, the in-flow control valve and the out-flow control valve are operable to provide a chosen flow rate of the liquid and a selected foam product flow rate at a selected density of the foam product.

摘要： The subject of the invention is a jet-system pipe laying procedure, characterized in that during drilling a driving medium containing water or water and air is transported from the driving medium container (5) by the pressure unit (1) into the driving medium transport pipe (17), and the driving medium is transported toward the head unit (3) and pressed out through the sprinkler (10) nozzles (13) in the direction of movement, thereby softening the soil in the direction of movement and making place for the head unit (3) and the pipe set (15) that follows. The subject of the invention also includes the device for implementing the procedure.
