DRILLING COMPONENTS AND SYSTEMS TO DYNAMICALLY CONTROL DRILLING DYSFUNCTIONS AND METHODS OF DRILLING A WELL WITH SAME
First Claim
1. A downhole drilling assembly for controlling a manner of engagement of a drill bit with a subterranean formation, comprising:
- a bottom hole assembly comprising a drill bit including at least one cutting structure thereon and a component configured to adjust at least one aspect of operation of the downhole drilling assembly that affects at least one of a force and a speed with which the at least one cutting structure may engage a subterranean formation being drilled by the drill bit;
at least one sensor configured to measure at least one downhole drilling parameter, and;
a processor operably coupled to the at least one sensor and the component to cause the component to adjust the at least one aspect of operation of the downhole drilling assembly responsive to input from the at least one sensor.

Abstract
Drilling tools that may detect and dynamically adjust drilling parameters to enhance the drilling performance of a drilling system used to drill a well. The tools may include sensors, such as RPM, axial force for measuring the weight on a drill bit, torque, vibration, and other sensors known in the art. A processor may compare the data measured by the sensors against various drilling models to determine whether a drilling dysfunction is occurring and what remedial actions, if any, ought to be taken. The processor may command various tools within the bottom hole assembly (BHA), including a bypass valve assembly and/or a hydraulic thruster to take actions that may eliminate drilling dysfunctions or improve overall drilling performance. The processor may communicate with a measurement while drilling (MWD) assembly, which may transmit the data measured by the sensors, the present status of the tools, and any remedial actions taken to the surface.

14. A method of drilling a well, comprising, while drilling:
-
measuring a value of at least one downhole drilling performance parameter associated with operation of a downhole drilling assembly having a drill bit at a distal end thereof; analyzing the at least one downhole drilling performance parameter value; adjusting at least a valve in the downhole drilling assembly in response to the analyzed at least one downhole drilling parameter value to alter at least one aspect of operation of the downhole drilling assembly; and
;repeating the measuring, analyzing, and adjusting until a desired downhole drilling performance parameter value is achieved. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method of drilling a well, comprising:
-
flowing drilling fluid through a bottom hole assembly including a drilling-fluid driven downhole motor and a drill bit; diverting substantial drilling fluid flow away from driving the downhole motor; engaging a formation to be drilled with the drill bit; and ceasing at least a portion of the diversion of drilling fluid flow. - View Dependent Claims (25)
