Simulating multiple ranges of critical conditions (RPM, WOB, hole over-gauge…) allows the choice of safer drilling parameters and avoid BHA resonance.
Vibration modal analysis software description
DrillScan Software Platform provides a very beneficial, user-friendly and essential tool for analysing drill string mechanical vibrations that may occur under specific critical conditions (rotation speed, WOB, hole overgauge).
With fast modelling results to forecast critical RPMs range for any type of BHA (rotary, RSS, motor, underreamer …), this module adds a strong value to all drilling phases.
The Vibration Modal Analysis module takes into account diverse excitation sources such as mass imbalance and additional rotation of steerable motor to improve simulation accuracy and help avoid bit-bouncing (axial mode of vibration), stick-slip (torsional mode of vibration) and whirling (lateral mode of vibration). This module provides modal deflection shapes at single depth for the three types of vibrations and as many modes as necessary.
It also allows multiple steps computations to follow critical vibrations along measured depth.
Vibration Modal Analysis results delivers straightforward and safe drilling parameters operating window.
