摘要：

大庆探区发现的徐深气田储量规模超1000×108m,是我国迄今为止发现的最大的火山岩气藏。徐深气田的发现经历了探索阶段、小型构造气藏发现阶段、大型岩性气藏突破阶段。徐家围子断陷具备好的烃源岩条件,火山岩发育,烃源岩、火山岩储层、区域盖层在纵向上形成了良好的生储盖组合条件,有利于大气藏的形成。

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
