Downhole drilling utilizing measurements from multiple sensors
First Claim
1. A method of controlling a downhole portion of a drill string, the method comprising:
- receiving one or more first signals from a first sensor package mounted at a first position to the downhole portion within a wellbore, the one or more first signals indicative of an orientation of the first sensor package;
receiving one or more second signals from a second sensor package mounted at a second position to the downhole portion within the wellbore, the one or more second signals indicative of an orientation of the second sensor package;
calculating a first amount of bend of the downhole portion between the first sensor package and the second sensor package in response to the one or more first signals and the one or more second signals; and
transmitting control signals to an actuator of the downhole portion in response to the first amount of bend, wherein the actuator is responsive to the control signals by adjusting the downhole portion to have a second amount of bend between the first sensor package and the second sensor package, the second amount of bend different from the first amount of bend.

Abstract
A system and method for controlling a downhole portion of a drill string is provided. The method includes receiving signals from a first sensor package mounted at a first position to the downhole portion, the signals indicative of an orientation of the first sensor package. The method also includes receiving signals from a second sensor package mounted at a second position to the downhole portion, the signals indicative of an orientation of the second sensor package. The method further includes calculating a first amount of bend between the first and second sensor packages in response to the signals and transmitting control signals to an actuator which responds by adjusting the downhole portion to have a second amount of bend between the first and second sensor packages.

12. A downhole portion of a drill string adapted to move within a wellbore, the downhole portion comprising:
-
a first sensor package at a first position, the first sensor package adapted to generate a first measurement indicative of an orientation of the first sensor package; and a second sensor package at a second position, the second sensor package adapted to generate a second measurement indicative of an orientation of the second sensor package; and a controller configured to calculate an amount of bend of the downhole portion between the first sensor package and the second sensor package in response to the first measurement and the second measurement. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
