Retrievable fluid flow control nozzle system for wells |
摘要 |
A system for controlling the flow of injection fluids and production fluids between a wellbore and one or more zones in a subterranean formation including an elongated tubing string extending within the wellbore and having one or more tubular ported mandrels interposed in the tubing string. Retrievable sleeves are insertable through the tubing string for registration with the mandrels in predetermined longitudinal and rotational positions as determined by a no-go shoulder on the mandrel and cooperating keys and key slots formed on the sleeves and the mandrels, respectively. The sleeves include removable orifice plugs which may be sized to control the flow of fluid through the sleeves between the tubing string and the wellbore. The sleeves are wireline insertable and retrievable so that changes in fluid flow control characteristics may be selectively carried out without pulling the tubing string from the wellbore.
