发明名称 SYSTEM AND METHOD FOR THRU TUBING DEEPENING OF GAS LIFT
摘要 The present disclosure is directed to a gas lift system adapted to provide a gas injection point to a deeper location in a wellbore. A turn-over suspensi on mandrel can be landed inside a side pocket mandrel and connected to a gas li ft valve on one end and a coil on the other end. A length of production tubing can extend from the side pocket mandrel. The production tubing can include a production packer to seal the annulus between the tubing and the well casing . The turn-over suspension mandrel can be constructed such that gas entering t he gas lift valve is directed down through the coil and into the wellbore benea th the production packer. A plug can be placed at the bottom of the coil in order t o prevent blowouts during installation of the gas lift system. An alternative embodiment of the present disclosure provides a coil and plug hung from a ga s lift valve of a pack-off assembly.
