Plunger lift is an artificial lift method by a plunger traveling up and down the tubing to remove these accumulated liquids from the wellbore.

In the present paper the various artificial lift methods are reviewed, and hydraulic pumping, rod pumping, gas lift and ESP methods as used for deep wells are disccussed.

This paper introduced the present situation and development tendency on the foreign completion technology,fracture acidizing,artificial lift,well workover,and laboratory experiment,it is useful for the development of the gas production engineering technique in China.

With the increasing of oil well and producing reserves, it is difficult for conventional artificial lift technology to meet the producing need.

The paper analyses the effect factors on ternary combination flooding lift technology,compare application conditions and economic benefit of three lift technologies in ternary combination flooding and select a lift technology suited for ternary combination flooding.

The reservoir performance is the design basis of the steam injection and the lifting technology, whereas, the steam injection and the lifting technology affect the reservoir performance.

Based on the research of viscosity?temperature relationship of heavy oil, lifting technology in deep wells and mixing light oil for viscosity reduction, the feasibility of lifting technology of hollow rod is studied.

For oil fields with low permeability and quite long production history,artificial lift and flooding methods are best choices.
