Title:
SYSTEM AND APPARATUS FOR MODELING THE BEHAVIOR OF A DRILLING ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2012/109663
Kind Code:
A3
Abstract:
A method for drilling a borehole includes obtaining, while drilling the borehole, sensor data for the drilling assembly, analyzing, while drilling the borehole, the sensor data using a drilling behavior model to obtain results, and adjusting the drilling of the borehole based on the results. The drilling behavior model models drilling of the borehole using a distance drilled, a number of touch points, a number of bend angles, a number of external moments, a number of lengths of distributed weights, a lateral displacement of a center of the borehole at a bit, at least one vertical displacement from the center of the borehole, at least one angular offset, at least one force, and at least one mass per unit length.
