随着松南气田的发现,松辽盆地长岭地区火山岩气藏取得了巨大的突破,寻找深层火山岩,刻画火山岩成为长岭地区寻找深层油气主要手段,经过研究得出该地区营城组上部火山岩主要为溢流相和爆发相在波形分类平面上主要表现为波形杂乱的地震相特点,碎屑岩主要表现为波形相对稳定的地震相特点。 With the discovery of the Songnan gas field, great breakthroughs have been made in the volcanic gas reservoirs in the Changling area of ​​the Songliao Basin. Looking for deep volcanic rocks and characterizing volcanic rocks, they have become the major means of finding deep-seated oil and gas in Changling area. The results show that the upper volcanic rocks of Yingcheng Formation in this area are mainly For the overflow phase and the explosive phase, the characteristics of the seismic facies mainly appear in the waveform classification plane. The clastic rocks are mainly characterized by relatively stable waveforms.
