Dual-Purpose Steam Injection and Production Tool |
摘要 |
A dual-purpose tool can be used for steam injection and production in a wellbore. A mandrel deploys in the wellbore to communicate steam in a steam injection operation and to communicate production fluid from the wellbore during production operations. A distributor on the mandrel has nozzles for injecting steam into the wellbore and has production valves for producing fluids from the wellbore. A screen can be used to screen production fluids as they are produced through the production valves. The nozzles can also allows produced fluids to flow into the mandrel, or backflow valves can be used to restrict flow of produced fluids through the nozzles while permitting the flow of steam out of the nozzles.
