Abstract
A positive displacement fluid motor can include a stator and a rotor. The stator can include a housing with opposite end connections that are the same. A method can include deploying a fluid motor into a well, operating the fluid motor by flowing fluid between a rotor and a stator of the fluid motor, retrieving the fluid motor from the well, and then reversing the stator on the rotor. Another positive displacement fluid motor can include a stator housing configured to receive a rotor into one end connection, and configured to receive the rotor into an opposite end connection.
Claims29
A positive displacement fluid motor, comprising:
- a stator;
- and
- a rotor configured to rotate in response to fluid flow between the stator and the rotor,
- in which the stator comprises a housing and at least one internal helical profile disposed between first and second end connections at respective first and second opposite ends of the housing, the first end connection being the same as the second end connection.
A method of utilizing a fluid motor with a subterranean well, the method comprising:
- deploying the fluid motor into the well;
- operating the fluid motor by fluid flow between a rotor and a stator of the fluid motor;
- retrieving the fluid motor from the well;
- and
- then reversing the stator on the rotor.
