PURPOSE: To increase wear and abrasion resistance and to attain the suppression of dust, reduction of noise and increase of a digging speed by ejecting fluid with compressed air during digging work, so as to cool a bit main body in an underground borer with a down hammer. CONSTITUTION: In a constitution where a rotary machine 4 has its bottom coupled with a screw shaft 3 and a down hammer B on a guide stilt 2 of a vehicle body 1, a supply unit 5 is interposed between the machine 4 and the shaft 3, a fluid conduit 6 and compressed air conduits 7, 7' are formed centrally of the shaft 3 and surrounding it. Then, a fluid jetting pipe 8 is arranged centrally of the hammer B to extend, until the inside of a bit body 9 so that water is discharged along with high-pressure compressed air from the center of the lower stage surface of the bit main body. | ||||||

PURPOSE:To smoothen the feeding of cooling fluid and to improve the life of a tool by inserting and fixing the narrow nozzle communicating with a cooling fluid-introducing hole into the hollow member which is connected to the joint of a tool body with sealing material and thrust bearing and is rotated in the tool for stone material, etc. CONSTITUTION:The rear end of a hollow member 8 is inserted into the fitting hole 24a of the joint member 24 supported on a tool body 2 and is connected thereto with the sealing by O ring 48. The hollow member 8 is rotationally driven by a driving shaft interlocking with the driven shaft 38 by gears 36, 44, and a rotary drill 18 fitted to the hollow shaft 8 is rotated. A narrow nozzle 30 is fitted into the cooling fluid-introducing port 24b of the joint member 24 with its connected rear end, and the front end is fitted to the narrow nozzle 34 in the rotary drill 18. By this construction, mist M may be fed in axial direction in the hollow member 8 directly and smoothly by the narrow nozzle 30 from the introducing hole 24b. | ||||||

PURPOSE: To feed enough coolant to a cut blade by energizing a turbine rotor partially in the axial direction by liquid stream, activating a collection nozzle, which is arranged at an outlet of the rotor to collect the liquid stream after deflection of this stream, as a mixing passage for sucking air and residual water from a turbine casing. CONSTITUTION: A rotor 20 is energized axially by a liquid stream 25 from a nozzle 24, and this stream 25 hits a rotor blade 21 as a vector characterized by a tangential direction component from 80% to 96%, an axial direction component from 20% to 40%, and radial direction component from 0% to 15%, and goes out from the rotor blade 21 with having the tangential direction component, the axial direction component, and the radial direction component. A collection nozzle 26 for collecting the stream 25 after deflection of this stream 25 is arranged at an outlet of the rotor 20, and functions as a mixing passage for sucking air and residual water from a turbine casing.

A method of servicing a wellbore in a subterranean formation comprising placing a foamed wellbore servicing fluid into a wellbore; flowing the foamed wellbore servicing fluid back to the wellbore surface; and contacting the foamed wellbore servicing fluid with an immobilized defoaming agent structure comprising an inert substrate and a defoamer. A system comprising a foamed wellbore servicing fluid in contact with a de-foaming structure, wherein the de-foaming structure comprises a defoamer covalently bonded to an inert substrate. | ||||||

The present invention provides apparatus and methods for handling fluids returning from a well. The fluids are introduced into a separator (110) and a separated gas stream (60) is recovered or recycled. The gas stream may comprise more than one phase. The separated gas stream is urged through a multiphase pump (200) before it is recovered. Alternatively, the return fluids may pass through a multiphase pump before it is introduced into the separator. | ||||||

Cuttings are removed from air drilling fluid used in an air drilling system by delivering the cuttings and air drilling fluid into an air-tight enclosure (22), decreasing the flow rate of the air through the enclosure (22) to allow the cuttings to settle and separate from the airflow and be contained within the enclosure (22). The air, substantially devoid of the cuttings, is discharged. The enclosure (22) is positioned at an angle to facilitate the discharge of the contained cuttings. Preferably, the enclosure (22) is of a size which will allow it to be transported on public highways without special movement permits, and the exhilarating equipment used may be contained within the enclosure (22) during transportation. |

59 | Apparatus and method for stimulating a subterranean well | EP98309135.6 | 1998-11-09 | EP0916805A3 | 2001-02-28 | Zeltmann, Thomas A.; Rahimi, Alireza B.; Ross, Colby, M. |
A method of stimulating a subterranean well permits each desired location within a portion of a well to be isolated from other portions of the well during stimulation operations therein, but does not require lining a portion of the well with casing and cement, and does not require the use of sealing devices, such as inflatable packers, in the well portion. In an embodiment, a stimulation method includes the steps of depositing a barrier fluid (32) in a portion of a well, forming a radially extending opening (56) through the fluid, and flowing stimulation fluids through the opening and into a formation surrounding the portion of the well. |

The invention relates to a method and a device for driving bore holes, specially exploring and extraction drillings in the sea bottom (40). According to the invention, the sea bottom is slackened by means of a rotating drilling head (10) which is fitted to the lower end of a drill string (5) designed for transmitting torque. The upper end of the drill string is mounted on a floating platform (1), wherein the drill string (5) is composed of at least two telescopically interfitting string parts (6, 7), which during a vertical movement of the platform, e.g. a movement induced by the sea swell, exert a relative movement with respect to each other so that the drilling head (10) rests with a substantially constant force on the surface to be cleared away. |
