    Abstract： Natural gas， as a kind of high quality， clean and efficient energy， is more and more widely used. Changqing Oilfield， located in the Ordos Basin， has such features as many stations， their wide distribution and disperse well site layout. In oil field production， wellhead associated gas is not enough large and con not be utilized economically， it is mostly discharged directly or burned， which results in valuable resource waste environmental pollution. In order to recovery such associated gas effectively， it is necessary to adopt oil pumping unit for downhole oil pumping. Analyze are functions and operation principle of oil pumping unit and introduced are technologies and methods for wellhead associated gas recovery. Conducted is comparative analysis on constant pressure valve technology， compressor pressurization technology and booster pump technology developed newly for wellhead associated gas recovery. Especially the booster pump technology has such advantages as low energy consumption， easy installation， convenient maintenance and good recovery capacity. Field application results show that the technology can recover a lot of associated gas， reduce environmental pollution and remarkable economic and social benefits can be obtained through application of the technology， which will provide valuable reference for associated gas recovery in domestic other oilfields， such as Daqing Oilfield， Liaohe Oilfield， etc.
