WELLBORE FLOW-CONTROL ASSEMBLIES FOR HYDROCARBON WELLS, AND SYSTEMS AND METHODS INCLUDING THE SAME
摘要
<p>Wellbore flow-control assemblies define a flow-controlled fluid conduit that selectively conveys a fluid flow, including fluid outflow and fluid inflow, between a subterranean formation and a casing conduit. The wellbore flow-control assemblies include a sacrificial flow-control device that defines a first portion of the flow-controlled fluid conduit and a directional flow-control device that defines a second portion of the flow-controlled fluid conduit. The sacrificial flow-control device resists the fluid flow prior to a flow- initiation event and permits the fluid flow subsequent to the flow-initiation event. The directional flow-control device permits one of fluid outflow and fluid inflow and resists the other.</p>
