SYSTEMS AND METHODS FOR FLOW REDUCTION OR ISOLATION IN A WELLBORE

摘要

Fluid flow reduction or cessation in a wellbore or pipe may be provided. A body member may be longitudinally translated through a wellbore or pipe. The body member may have an external wall facing an internal wall of the wellbore or pipe. The body member may have an internal flow path configured to facilitate communication of fluid within the wellbore or pipe through the body member. A braking force may be applied to the body member to slow and stop translation of the body member through the wellbore or pipe. A first fluidic seal may be provided between the external wall of the body member and the internal wall of the wellbore or pipe. The first fluidic seal may restrict fluid within the wellbore from being communicated between the external wall of the body member and the internal wall of the wellbore or pipe. A second fluidic seal may be provided restricting fluid within the wellbore or pipe from being communicated through the internal flow path of the body member.
