A field test and sampling data of associated gas of Changqing Oilfield were analyzed, starting from two aspects: variation of petroleum characteristics and recovery feature(characteristics), and by classifying different water content levels and application of the mathematical statistical method, features of production performance of associated gas were investigated and discussed . The changes of factors of formation pressure , production gas- oil ratio, bottomhole flowing pressure, and water content etc are discussed, and the basic features of production performance of associated gas are summarized, it provides a reliable basis for an integral application of associated gas in oilfields.
