Abstract
A downhole intelligent Circulating Sub controller detects the difference between rotary drilling and sliding drilling, responds appropriately and quickly to multiple changes between rotary drilling and sliding drilling that may occur several times each stand of pipe. Additional controls prevent actuation of the Circulating Sub at inappropriate times. In one embodiment, a separate modular control sub is disclosed that may be utilized with and/or removably secured to a Circulating Sub and/or other types of downhole tools.
