摘要： A gas lift production apparatus is provided for use in flushing and snubbing well operation. The apparatus comprises upper production string and lower production string. The upper production string includes at least one side pocket mandrel carrying a gas lift valve, tubular strings connected with every side pocket mandrel, a sliding sleeve installed as part of the production string below side pocket mandrels and a latch seal assembly threaded in the tubular string below the sliding sleeve. The lower production string includes a single bore packer below the latch seal assembly, tubular strings, a landing nipple and a bell mouth at the bottom of the production string. The upper production string are run in and removed as a single unit from the packer which is anchored within the well casing. It is emphasized that this apparatus is provided with three functions such as producing a gas lift well, flushing well and snubbing well operation. Application of the apparatus will prevent flushing or killing fluid from polluting the reservoir and increase production efficiency.
