MULTI-ZONE ACTUATION SYSTEM USING WELLBORE PROJECTILES AND FLAPPER VALVES

摘要

An example sliding sleeve assembly includes a body that defines an inner flow passageway and one or more ports. One or more sensors are positioned on the body to detect wellbore projectiles that traverse the inner flow passageway, and a sliding sleeve is arranged within the body and movable between a closed position, where the sliding sleeve occludes the one or more ports, and an open position, where one or more ports are exposed. A flapper valve is arranged within the body and movable between an open configuration, where the flapper valve allows fluid flow through the inner flow passageway, and a closed configuration, where the flapper valve seats against a flapper seat defined on the sliding sleeve and prevents fluid flow through the inner flow passageway. An actuation sleeve is arranged within the body and movable to allow the flapper valve to move to the closed configuration.
