摘要： The objective of the present invention is to provide a device for controlling the drilling direction of the drills by which the drilling direction can be accurately detected, the bit load and the vibration affecting on the weakly-structured double eccentric mechanism portion can be controlled, and the rigidity of the rotating shaft is enhanced. The device for controlling the drilling direction of the drills comprises a cylinder-type housing (6), the first ring-formed component (11) which is located on an inner peripheral surface that is eccentric with respect to the cylinder-type housing (6), the second ring-formed component (12) which is located on the inner peripheral surface that is eccentric with respect to said circular inner surface of the first ring-formed component (11), and the hollow-type harmonized reduction gears (13, 14) which rotate the first and second ring-formed components (11, 12) relatively around their respective centers, and the said device for controlling the drilling direction of the drills is operated to determine the position of the rotating shaft (2) by individually rotating the first and second ring-formed components (11, 12). In said device for controlling the drilling direction of the drills, a resolver is positioned between the first and second ring-formed components (11, 12) and the hollow-type harmonized reduction gears (13, 14) to detect the rotating angular position of the first and second ring-formed components (11, 12). Furthermore, a fulcrum bearing (8) of the rotating shaft (2) is located at a midpoint between the drill bit and the first and second ring-formed components (11, 12). Moreover, a flexible joint (3) is located at the upper portion of the first and second ring-formed components (11, 12) and a bearing (15) is further mounted on the flexible joint in order to support the rotating shaft (1).

摘要： A floating vessel carrying a digging apparatus with a required offshore structure for digging a well in the sea bed. A riser extending from the vessel into the well in the sea bed surrounds a drill string so as to provide a circulation of dug muddy water and dug fluid. This riser is constituted by at least two segments that can detachably be connected to each other, and one of the two can move together with the floating vessel, while the other stays at a predetermined location until the two segments are connected to each other again by providing buoyancy. A riser system for use for a producing operation is also provided that comprises at least two detachable segments.

摘要： A sample container (21) filled with a sample of crude crashed rocks is loaded into a thermal decomposition furnace (1), and this thermal decomposition furnace (1) is evacuated to substantial vacuum by connecting it to a vacuum suction line (27), and is then sealed. The sealed furnace (1) is rapidly heated to a first temperature at which some proportions of hydrocarbons are thermally decomposed but inorganic carbonates are not decomposed, and is retained at this temperature for a predetermined time. After the thermal decomposition furnace (1) is cooled to a temperature at which the hydrocarbons inside the furnace do not react with air, it is connected to an air feed line (29) and to an exhaust line (35) and the produced gas inside the furnace is passed through a hydrocarbon detector (34) and through a CO2 detector (33). An HC peak (P1) and a CO2 peak (P3) are determined from the output signals of these detectors and are recorded. Then, the temperature of the thermal decomposition furnace (1) is set to a second temperature which is higher than the first temperature and at which insoluble organic matters are substantially decomposed thermally, and each of the steps of exhaust, heating, cooling and measurement is again carried out so as to determine and record at least an HC peak (P2). Types, contents, etc., of the organic matters are judged from these peaks (P1, P2 and P3).
