    摘要: The present invention recites a downhole motor and method of fabricating the same, wherein the method for fabricating a stator for a downhole motor includes the providing of a mandrel having an outer geometry that is complimentary to a desired inner geometry for the stator and the application of a flexible sleeve over the mandrel. Additionally, a stator tube having an interior surface is provided and a bonding agent is applied to the interior surface of the stator tube. The flexible sleeve and the mandrel are placed in the stator tube and a reinforcing material is introduced into the stator tube to fill space between the flexible sleeve and the stator tube. The reinforcing material is solidified and serves to bond the reinforcing material to the flexible sleeve and the stator tube.

    摘要: A flexible drive shaft for connection to the rotor of a progressive cavity pump or motor, in which the drive shaft 7, provided with a coating 26, is formed of titanium or similar metal. A relatively inexpensive metal flanged head portion is fastened, e.g. by adhesive, to an end portion 12, of the drive shaft, and is bolted to the rotor 10. The structure enables a relatively shorter drive shaft to be used which is capable of transmitting heavy torque.

    摘要: A fluid machine has-two working mechanisms. Each of the working mechanisms has a fixed spiral, a movable spiral, and a working chamber. The fixed spiral has an inner contact face that spirals from the periphery toward the center of the fixed spiral and has a stepped shape in section. The movable spiral has an outer contact face that spirals upwardly from the periphery toward the center of the movable spiral and has a stepped shape in section. The movable spiral orbits inside the fixed spiral when an eccentric shaft rotates. The working chamber is defined between the inner and outer contact faces. The height and width of the working chamber become smaller as the working chamber shifts from the periphery toward the center of the working mechanism according to the oscillation of the movable spiral.

    摘要: A modular measurement while drilling sensor assembly is presented. A typical cross-over assembly for mating with a measurement while drilling (MWD) tool is connected to a typical positive displacement mud motor (e.g., a Moineau motor). A modular sensor assembly comprises two portions, an upper drive shaft portion which includes a flexible shaft connected to the motor and a lower sensor portion and supported by a radial bearing. The lower end of the flexible shaft is connected to a hollowed shaft which extends beyond the lower end of the upper drive shaft portion and which is supported by a radial bearing. The lower sensor portion has a central channel extending longitudinally therethrough, with the lower portion of the hollowed shaft extending through this channel. The sensor portion may comprise any type of MWD sensor, however the present invention is preferably used with sensors (e.g., formation evaluation sensors) that benefit from obtaining measurements close to the bit. The lower end of the hollowed shaft is supported with a radial bearing and connected to a flexible shaft of an adjustable kick off assembly connected to the sensor portion. The adjustable kick off assembly allows the introduction of a kick off angle, generally between 0.degree. and 3.degree., in the assembly. The adjustable kick off assembly is connected to a typical bearing pack assembly. The lower end of the bearing pack assembly is typically connected to a drive shaft, a bit box and then the bit.

    摘要: The screw machine comprises consecutively mounted screw mechanisms (6, 7 and 8, 9) incorporating coaxially arranged stators (10, 12 and 14, 16) and rotors (11, 13 and 15, 17) disposed therein whose axes are offset with respect to the central axis of the stators (10, 12 and 14, 16) by the amount of eccentricity "e" of the screw mechanisms (6, 7 and 8, 9). The screw mechanisms (6, 7 and 8, 9) are grouped into modules (4, and 5) and the modules proper are grouped into blocks (3). The axes of the rotors (11, 13, 15, 17) of the screw mechanisms (6, 7 and 8, 9) in the module (4 and 5) and the modules (4, and 5) proper in the block (3) are arranged symmetrically relative to the central axis.
