  • Multiple stage drag and dynamic turbine downhole motor
    Patent number: 5112188
    Abstract: A multistage turbine is provided for driving a downhole motor, which is driven by the flow of a fluid therethrough. The turbine comprises a housing and a shaft positioned in the housing, the shaft rotating about the longitudinal axis thereof. A plurality of turbine stages are mounted on the shaft for rotation therewith, each turbine stage including a rim coaxial with the shaft and a plurality of turbine blades fixed to the rim. A plurality of flow directing stators are positioned between adjacent turbine stages, each of the stators having a wall portion and diverter portion, wherein the wall portions are perpendicular to the axis of the shaft and the diverter portions are at an angle of less than 90.degree. with respect to the axis of the shaft.

  • Multiple stage drag turbine downhole motor
    Patent number: 5098258
    Abstract: A multistage drag turbine assembly is provided for use in a downhole motor, the drag turbine assembly comprising an outer sleeve and a central shaft positioned within the outer sleeve, the central shaft having a hollow center and a divider means extending longitudinally in the hollow center for forming first and second longitudinal channels therein. A stator is mounted on the shaft. The stator has a hub surrounding the shaft and a seal member fixed to the hub, wherein the hub and the shaft each have first and second slot openings therein. A rotor comprising a rotor rim and a plurality of turbine blades mounted on the rotor rim is positioned within the outer sleeve for rotation therewith with respect to the stator such that a flow channel is formed in the outer sleeve between the turbine blades and the stator.

  • Double cone cutting head for a drill bit
    Patent number: 4967854
    Abstract: The present invention is directed to a cutting head for use in a rotary drill bit in which the cutting head comprises a stem and a base integrally formed with the stem. The base has a first cutting surface defined by a frustrum of a cone or other shape and a second cutting surface defined a cone or other shape, wherein the first and second cutting surfaces are coaxial with the axis of the cutting head. The cutting head is adapted to be attached to a drill bit such that the axis of the cutting head is oriented at an angle with respect to the axis of the drill bit.
