DOWNHOLE SURVEYING UTILIZING MULTIPLE MEASUREMENTS

摘要

Systems and methods for controlling a drill string are provided. A method comprises receiving one or more first signals from a first sensor package mounted in a first portion of the drill string at a first position within a wellbore. The first signals may be indicative of an orientation of the first portion of the drill string. The method also includes receiving one or more second signals from a second sensor package mounted in a second portion of the drill string at a second position within the wellbore. In certain embodiments, the second signals indicative of an orientation of the second portion of the drill string. The drill string may be adapted to bend between the first portion and the second portion and certain embodiments include calculating a first amount of bend between the first portion and the second portion in response to the first signals and the second signals.
