    摘要: A system of apparatus for the controlled directional drilling of a deviated well bore into the earth has a fluid operated drilling motor and drill bit secured on the bottom end of a drill string. The drill bit is supported for angular drilling relative to a substantially vertical well bore by either using a bent sub for supporting the drilling motor or by using a drilling motor with a bent housing or a combination of the two. A bypass tool is connected to the bent sub or motor housing, an orienting sub and mule shoe keying sub are connected to the bypass tool, and a surveying tool is connected in the drill string above the orienting sub and mule shoe sub. The bypass tool is in fluid connection with the motor and has a telescopic housing and a valve for circulating fluid into the bore hole to flush cuttings and debris therefrom. The surveying tool determines and controls the direction of drilling. The orienting sub and mule shoe keying sub orients the position of the motor and drill bit in relation to the surveying tool.

    摘要: An earth drilling apparatus has a pneumatic motor operated earth drilling tool, a valve assembly connected to the motor, and a drill string connected to the valve and to a source of pneumatic fluid. The drilling tool has an earth drilling bit and a rotor/stator motor section to apply a rotational force to rotate the bit at the bottom of the string. The valve assembly is disposed between the drilling tool motor and the source of pneumatic fluid and controls the flow of pneumatic fluid to the tool. The valve assembly has a pneumatic pressure-operated valve which is operable in response to the pressure of pneumatic fluid in the drill string to be opened to permit flow of pneumatic fluid to the tool at a predetermined operating pressure to transmit an initial pulse of pneumatic fluid to initiate operation of the motor. The valve is kept open at a lower pressure than that required to open it. The valve is a pressure operated valve, spring-loaded toward closed position, which opens at a first predetermined pneumatic pressure permitting flow to said tool and closes at a second, substantially lower, pneumatic pressure.

    摘要: A downhole motor and bearing assembly for high pressure operation has a tubular housing with an inlet and outlet for flow of drilling fluid. A stator is supported in the housing and a rotor is supported for rotary movement in the stator. An open tubular shaft is connected to the rotor for rotary movement in the housing. The bearing assembly has bearing members in the housing in fixed spaced relation for carrying downward and upward longitudinal thrust loads. Since the motor is designed for high pressure operation, conventional bearings tend to wear out rapidly. In this motor and bearing assembly, the pressure of drilling fluid passing through the motor is bled into the down hole side of the bearings where the pressure is applied against an upset on the bearings shaft having an exposed area on the lower side sufficient to produce an upward thrust partially or completely offsetting the downward thrust produced by the pressure drop across the drill bit. The pressure balanced bearing assembly is operable in combination with any motor operating on flow of fluid, including Moineau motors, turbodrills, etc.

    摘要: An insulated drill collar gap sub assembly for a toroidal coupled telemetry system including a first annular sub member (150) operable to be connected at one end to a drill collar and a second annular sub member (156) operable to form a part of a drill collar sub. The first and second annular sub members have interconnecting structural members (54, 58) operable to structurally interfere. The interconnecting structural members are dimensioned to form a continuous gap (160) between mutually opposing surfaces and a dielectric material (162) fills the gap to electrically isolate the first annular sub member with respect to the second annular sub member. A bearing member (164) is positioned between the first annular member and the second annular member and is coated with a dielectric insulation (166) to facilitate the formation of a drill collar gap sub assembly of structural and electrical integrity.

    摘要: A conveyor 4 driven by a motor 5 feeds thermoplastic waste material 2, such as the trimmed-off edges of extruded plastics sheets, to a compression chamber 8 at the inlet of a heating box 10 of an extruder 11. The conveyor operates intermittently in synchronism with the movement of a plunger 40 operated by a hydraulic cylinder 42 which compresses the waste material to the level of a restraining member 50 controlled by a pneumatic cylinder 54. The member 50 comes into operation as the plunger 40 reaches the bottom of its stroke and holds the plastics material in a compressed condition while the plunger 40 rises again, further material 2 is fed to the chamber 8 and the cycle is repeated, the member 50 being withdrawn shortly before the plunger 40 reaches the bottom of its stroke. Plastics material is progressively melted as it passes down the box 10 and under the pressure exerted by the compressed material is extruded through a die plate 16 in the form of strands 18 which, after passing through a water bath 20, are chopped into granules 35 by a rotary cutter 34 and fall into a bin 36 ready for re-use.
