Fluid Control Apparatus and Methods For Production And Injection Wells |
摘要 |
Flow control systems and methods for use in injection wells and in the production of hydrocarbons utilize a particulate material disposed in an external flow area of a flow control chamber having an internal flow channel and an external flow area separated at least by a permeable region. The particulate material transitions from a first accumulated condition to a free or released condition when a triggering condition is satisfied without requiring user or operator intervention. The released particles accumulate without user or operator intervention, to control the flow of production fluids through a flow control chamber by at least substantially blocking the permeable region between the external flow area and the internal flow channel.
