摘要 |
System, methods and devices for measuring and predicting complex borehole geometries are presented herein. A method is disclosed for determining a trajectory of a borehole that is generated by a drill string. The method includes: receiving data indicative of one or more drilling parameters between at least two survey points; averaging the received data over predetermined increments between the at least two survey points; calculating from at least the averaged data a predicted drill string response for each of the predetermined increments; determining from at least the predicted drill string response a change in inclination and azimuth for each of the predetermined increments; generating a predicted wellbore trajectory from the change in inclination and azimuth; comparing the predicted wellbore trajectory to a measured wellbore trajectory; and, if the comparison is favorable, determining a probable borehole position from the change in inclination and azimuth for each of the predetermined increments. |
