摘要： A system for drilling a well comprises a drill string in a wellbore having a bit at a distal end thereof. At least one sensor measures a drilling parameter. A computer controller has a set of instructions stored therein to process the measured drilling parameter over a drilled interval to calculate, in substantially real time, an updated friction slope and an updated worn bit slope and to calculate an updated drilling parameter for at least a portion of the wellbore based on the updated friction slope and the updated worn bit slope.

摘要： Methods and systems for improving delivery and retrieval of fluids to and from a downhole location are disclosed. A dual string pipe (202) is provided which comprises an outer pipe (206), an inner pipe (204) positioned within the outer pipe, and a bottom hole assembly (210) fluidically coupled to the outer pipe and the inner pipe. A diverter sub (208) is coupled to the inner pipe and is selectively operable in a normal drilling mode and a high flow mode. In the normal drilling mode a fluid is directed downhole through the inner pipe and in the high flow mode a return fluid is directed uphole through the inner pipe.

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.
