FIELD: measuring equipment.
SUBSTANCE: method for measuring micro-slips and micro-jams in a downhole motor is provided. It includes the following stages: placing in the borehole a downhole motor with an elastomeric stator and at least one fiber-optic sensor inside the elastomeric stator; obtaining a measurement value corresponding to the tension inside the elastomeric stator from the fiber-optic sensor; and processing a measurement value to determine the frequency of at least one of the micro-jams and slips of the downhole motor.
EFFECT: increase in the service life of the downhole motor by reducing the loads on the elastomeric stator.
