摘要： A drilling system may include an outer sleeve, and a rotary steerable module including a shaft extending within the outer sleeve. The rotary steerable module may further include bearings disposed within the outer sleeve and through which the shaft extends, and cams positioned along the shaft between the bearings. Each cam may include an eccentric ring through which the shaft extends. Each extension of the shaft through one of the eccentric rings defines a bend in the shaft within the outer sleeve, the bend having a bend angle. A method of use and a drilling control apparatus are also provided.

摘要： Disclosed are systems and methods for automatic weight on bit sensor calibration and regulating buckling of a drillstring. One method includes taking a first survey recording at a first depth within a borehole, the first survey recording providing inclination and azimuth of a drillstring at the first depth, measuring a weight on a drill bit at the first depth with a sensor sub arranged on a bottom hole assembly, the bottom hole assembly forming part of the drillstring and the drill bit being disposed at an end of the drillstring, calculating a predicted borehole curvature at a second depth within the borehole, the predicted curvature including a predicted inclination and a predicted azimuth of the drillstring at the second depth, calculating a weight correction value based on the predicted hole curvature, and calibrating the sensor sub with the weight correction value.

摘要： An illustrative dogleg severity (DLS) estimation method includes: retrieving dimensions of steering assembly; determining an initial DLS estimate; using the DLS estimate in combination with the steering assembly dimensions to determine node displacements for a shaft portion of the steering assembly; deriving a bit side force from the node displacements while accounting for elastic bending in a housing portion of the steering assembly; performing a DLS calculation based in part on the bit side force; adjusting the DLS estimate if the DLS calculation does not match; repeating said using, deriving, performing, and adjusting until a match is achieved; and storing the DLS estimate on a nontransient information storage medium.

摘要： In accordance with embodiments of the present disclosure, systems and methods for utilizing hybrid mechanical-laser drilling tools, such as drill bits and hole-openers, are provided. Such drilling tools may include mechanical cutters in addition to laser cutting mechanisms designed to focus laser beams toward a subterranean formation. The mechanical cutters and laser cutting mechanisms may work in combination to advance a wellbore through the subterranean formation. The drilling tools may be controlled to vary the amount of energy output through the mechanical drilling via the cutters and through the laser-assisted drilling via the lasers.
