原始语种摘要: Abstract(#br)Drilling optimization is typically tackled by optimizing the rate of penetration (ROP). However, most ROP optimization models do not consider the effect of drilling vibrations, a major ROP inhibitor. To resolve this limitation, this paper introduces a workflow that combines the ROP optimization process with a machine learning-based vibration model. This model determines optimal drilling parameters that not only increase ROP but mitigate excessive vibrations. Analytical ROP models are used to model the ROP in a given formation. An optimization algorithm (gradient ascent with random restarts) is used to find the optimal drilling control parameters, weight on bit (WOB) and revolutions per minute (RPM), required to improve ROP ahead of the bit. The vibrations classification model...
