The genesis of shallow gas in Hongxing area has been studied through analysis of its contribution pattern, controlling factors and pool-forming characteristics. Hongxing area is closely adjacent to Jiazhangsi depression which is an important hydrocarbon source for both deep oil reservoirs and shallow gas reservoir. With a later activity history, Jiazhangsi fault supply the migration path and trap structure for the shallow gas. Data of carbon isotope and chromatogram demonstrate that the shallow gas is high mature pyrogenation gas which has original relationship with the oil reservoirs of Es1. Along the faults, the gas and oil from the deep oil reservoirs of Es1 moved to the shallow position and assembled in the favorable trap, forming the shallow gas reservoir. The production of shallow gas has reached to a high scale. The shallow gas is important in improving the condition of natural gas exploring and development in Liaohe oil field.
Key words: Shallow gas; Genesis; Exploring importance; Hongxing area; Liaohe oilfield.
