发明名称 PORTED VELOCITY TUBE FOR GAS LIFT OPERATIONS
摘要 An apparatus for use with a packer set within a well bore comprises a first flow path providing fluid communication between the well bore above the packer and the well bore below the packer, and a second flow path. A system for gas lifting fluids from a well bore with a packer set therein defining an upper portion and a lower portion of the well bore comprises production tubing, the packer, and a ported velocity tube. A method for producing a fluid from a well bore zone below a set packer disposed in a production tubing comprises injecting a gas into a well bore annulus formed by the production tubing, flowing the gas downwardly through the packer, jetting the gas into the well bore zone, and flowing the fluid upwardly through the packer into the production tubing.
