摘要： A method and apparatus for changing the speed of a drill bit down hole in a fluid-actuated motor, including a positive displacement motor and a hydraulic motor, is disclosed. The apparatus comprises a bypass valve installed in the motor for controlling flow through and around the power section of the motor. When closed, the bypass valve forces all fluid to flow through the power section of the motor, imparting maximum speed to the drill bit. When opened, a portion of the fluid flow is allowed to flow around the power section of the motor, thereby reducing the speed of the drill bit. The bypass valve may be opened or closed mechanically, electrically, hydraulically, pneumatically, or by any other means, including a removable plug.

摘要： A turbine is disclosed which includes a turbine blade housing having an inner facing portion of a first material having a first coefficient of expansion, and a turbine blade body having an outer facing portion of a second coefficient of expansion greater than said first coefficient. In a preferred embodiment, the blade housing comprises a number of steel shroud rings and the turbine blade body comprises a number of stators and rotors of a thermoplastic material. An interference fit between stator blades and the shroud rings is enhanced in use due to the difference in thermal and/or hydrophilic coefficients of expansion of the first and second materials.

摘要： A fluid lubricated bearing assembly for use with an in-hole fluid motor has a housing and a shaft supported in the housing by a plurality of stacked adjustable bearings, through which thrust is transmitted to the shaft from a single thrust transfer point in the housing. The thrust bearings are individually adjustable to eliminate tolerance and thrust elements transfer load from the housing to the bearings from the single thrust transfer point. In the preferred form, the thrust elements include a flow restrictor sleeve in thrust transmission relation with bearings at opposite sides thereof. The flow restrictor sleeve cooperates with a companion flow restrictor sleeve on the shaft to limit the flow of fluid through the bearings from the motor. Radial contact bearings at opposite ends of the flow restrictor support the flow restrictor sleeves to minimize wear and resist bending forces applied radially of the sleeves.

摘要： A turbo drill which is connected to a string of drill pipe as a rotating shaft for driving a drill bit which may be a rotary bit or a high speed solid head diamond bit. The turbine section has rotor and stator blades which are crescent shaped in cross section with each blade having an exit angle of 14.degree.- 23.degree. from maximum turbine efficiency. The bearing shaft is provided with chevron rotary seals positioned below the rotary bearings carrying both radial and vertical thrust. Fluid lubricant fills the space from the rotary seals to a predetermined level above the bearings. A piston seals the lubricant chamber and is pressurized by drilling fluid (i.e., mud) flowing through the tool. A layer of lubricant fluid overlies the first piston and has a second piston covering said fluid and transmitting pressure from the drilling fluid to the lubricant fluid surrounding the bearings. A plug member in the bearing shaft is positioned to be dislodged at the low lubricant position of the first piston to provide a temporary obstruction to the flow of drilling fluid to give an indication, at the well surface, of loss of lubricant in the turbo drill. An optional feature provides for increasing the pressure drop of drilling fluid in the turbo drill to cause the vertical thrust to be carried on the bottom vertical thrust bearings, after the top vertical thrust bearings are worn, and thus extend the drilling life substantially. A further optional feature is a locking ring arrangement which prevents separation of threaded connections in the drill housing during use.
