摘要： A method of transmitting pressure pulses from a downhole location through a flowing fluid in a wellbore comprises using a linear actuator to controllably move a reciprocating member axially back and forth between a first position and a second position to at least partially obstruct flow of the flowing fluid to generate the pressure pulses. A reciprocating pulser for generating pressure pulses in a fluid flowing in a wellbore, comprises a fluid passage that allows flow of the fluid through the pulser, and a reciprocating member. A linear actuator is coupled to the reciprocating member, such that the linear actuator moves the reciprocating member in a first axial direction and then in a reverse direction to at least partially obstruct flow of the fluid through the pulser to generate pressure pulses in the flowing fluid.

摘要： A magnetic coupling includes an inner mover including an inner magnet region including a plurality of magnets disposed in circular arrangement around an axis of rotation. The coupling also includes an outer mover surrounding the inner magnet region, the outer mover including an outer component and an inner component, wherein the inner component and outer component are separated from each other in a first location and a second location. The coupling further includes a first magnet disposed in the first location and having a first polarity and a second magnet disposed in the second location adjacent to the first magnet and having a second polarity opposite the first magnet. The first and second magnets each include two endpoints and have a depth measured from an inner magnet surface to an outer magnet surface measured in a radial direction extending from the axis of rotation, the depth decreases from a maximum value to a minimum value, the minimum value being measured at the endpoints.
