ROTARY STEERABLE TOOL EMPLOYING A TIMED CONNECTION

摘要

A downhole steering tool (100) includes distinct hydraulic and electronics modules (110,160) deployed about a shaft (105). The hydraulics module (110) includes a plurality of hydraulically actuated blades (150). The electronics module (160) includes electronic circuitry configured to control blade actuation. The hydraulics and electronics modules (110,160) are physically and electrically connected to one another via a timed connection (250).
