Method and system for detecting conditions inside a wellbore |
摘要 |
Embodiments of methods and systems for detecting conditions inside a wellbore according to the invention are disclosed. One embodiment of the invention of the system includes a pipe ( 150 ) that is configured to rotate in a wellbore ( 140 ). A first detector ( 120 ) is located near the surface and is configured to measure a first parameter that correlates to rotation of the pipe ( 150 ). A second detector ( 160 C) is located at a first depth away from the surface and is configured to measure a second parameter that correlates to rotation of the pipe ( 150 ). A circuit ( 130 ) is coupled to the first detector ( 120 ) and the second detector ( 160 C) and is configured to compare the first and second parameters.
