| 224 | Method and apparatus for forming and using a bore hole | EP81303257 | 1981-07-15 | EP0044706A3 | 1982-12-22 | Dickinson III, Ben Wade Oakes |
A system for the formation and use of a bore hole, particularly for the recovery of oil from an oil-bearing underground formation. An eversible elongate permeable tube (100), preferably formed of woven cloth, including outer and inner walls, (102, 104), connected at a rollover area (106), is urged into the formation by a driving fluid. Drilling fluid is pumped through a central passageway (120) in the tube and carries a central pipe forward (122). The drilling fluid assists break-up of the formation to form a cuttings slurry which passes back along the outside of the eversible tube (100). Means is provided for turning the tube, as from the vertical to the horizontal, by use of a turning segment in the eversible tube. Such pipe preferably includes a flexible helical segment (122b) capable of turning and of serving as the ultimate support casing. Also, gravel packing techniques. |

| The invention relates to the installation of chains of measurement sensors on a flexible cylindrical tube (TB). The chains comprise multiple elongate sensor housings, electrically connected to one another by connecting cables. Each housing has two ends, in the elongation direction, connected to an upstream connecting cable and a downstream connecting cable, respectively, the upstream cable and the downstream cable mainly following two parallel helical paths (Ha1, Hb1), separated at the points of connection to the housing by a distance D other than zero in the direction of the axis of the tube. The housing is placed between the two cables and arranged with the elongation direction thereof parallel to the axis of the helical paths, which is the axis of the tube. The sensors of one chain are located on a single generatrix of the cylindrical tube and, if there are a plurality of chains, said sensors are positioned on a plurality of generatrices (G1, G2, G3). The sensor housings and the cables are placed in recesses and grooves provided in the periphery of the tube. | ||||||
