DOWNHOLE MOTOR SENSING ASSEMBLY AND METHOD OF USING SAME |
| 摘要 |
A downhole sensing assembly for sensing motor parameters of a downhole motor positionable in a wellbore penetrating a subterranean formation is provided. The downhole motor has a stator and a rotor rotatable within the stator. The sensing assembly includes at least one rotor extension operatively connectable to the rotor and movable therewith, at least one marker positionable about the rotor extension, and at least one motor sensor positionable about a downhole tool and operatively coupled to the marker to detect movement of the marker whereby motor parameters, such as rotational speed of the motor, are detectable. |

1. A downhole sensing assembly for sensing motor parameters of a downhole motor positionable in a wellbore penetrating a subterranean formation, the downhole motor having a stator and a rotor rotatable within the stator, comprising:
at least one rotor extension operatively connectable to the rotor and movable therewith; at least one marker positionable about the at least one rotor extension; and at least one motor sensor positionable about a downhole tool and operatively coupled to the at least one marker to detect movement of the at least one marker whereby motor parameters comprising rotational speed of the downhole motor are detectable. |
