SYSTEM AND METHOD TO LOCATE, MONITOR AND QUANTIFY FRICTION BETWEEN A DRILLSTRING AND A WELLBORE |
摘要 |
Disclosed herein is a method of locating and quantifying friction between a drillstring and a wellbore. The method includes, positioning a plurality of sensors within a wellbore, communicatively coupling the plurality of sensors, monitoring signals from the plurality of sensors, logging the sensed signals versus time versus depth of each of the plurality of sensors, locating at least one friction zone along the drillstring within the wellbore based on the logging and quantifying friction in the at least one friction zone based on the logging.
