Abstract: Based on the resources potential in the west region of southern Songliao Basin, its exploration fields can be divided into downwarping tectonic-sequence and fault-depression tectonic-sequence units,in which the major exploration targets of downwarping tectonic-sequence include both tectonic oil-gas reservoirs such as inverse tectonic belt, slope low amplitude structure group ,and nontectonic oil-gas reservoir such as stratigraphy and lithologic reservoirs .While themajor exploration targets of fault-depression tectonicsequence include conventional natural gas and non-conventional natural gas reservoirs.Therefore, it is put forward that stratigraphic - lithologic reservoirs in this area would gradually become important targets for exploration, and pointed out different techniquemeasures would be taken to explore different-order objects .
