Abstract:

Geological reserves of Xushen gas field discovered in Daqing exploration area exceed 100 bcm,the biggest among the volcanic gas reservoirs in China so far.The discovery of Xushen gas field had experienced several stages,including initial exploration,discovery of small structural gas reservoirs,and discovery of large lithologic gas reservoirs.Xujiaweizi fault depression has ideal source rocks and well-developed,volcanic reservoirs,which together with regional seals form vertically excellent source-reservoir-cap rock combinations,thus is quite favorable for the formation of large gas fields.

Key words: deep natural gas, exploration history, Songliao Basin
