Method of monitoring the drilling of a well (13) using an installation (11) comprising a drilling rig (17) floating on the sea (24) the method comprising the steps of:
- obtaining an injection flow rate of a drilling fluid,
- measuring a flow of a drilling mud recovered from the well in a discharge pipe (25) connected to a diverter (23) of the slip-joint at a discharge measurement point (C),
- selecting a comparison point (C') located between the diverter and the discharge measurement point,
- obtaining a slope value (0) representative of an angle of the discharge pipe with respect to a horizontal plane (P.
- modeling a flow of the drilling mud along the discharge pipe
- calculating a first flow rate of the drilling mud at the comparison point using the injection flow rate, and a second flow rate at the comparison point using the measured discharge flow rate, and
- performing a comparison between the first drilling mud flow rate and the second drilling mud flow rate to monitor the drilling. |
