摘　　要：2002年随着徐深1井在火山岩中获得日产百万立方米的高产工业气流,揭开了大庆深层火山岩气藏勘探开发的序幕。目前徐深气田火山岩气藏天然气储量已占该区天然气总储量的89.8%,成为我国东部陆上发现的最大气田,而火山岩气藏储层描述困难则是制约该区深层天然气勘探开发的"瓶颈"。为此,介绍了通过多学科联合攻关研发所形成的火山岩岩性岩相描述、测井火山岩岩性识别、地震火山岩体识别等火山岩气藏储层描述配套技术。这套技术为徐深气田火山岩气藏的高效开发奠定了基础,填补了我国在这类气田储层综合描述技术方面的空白。Xushen-1 tested a large gas flow rate over 1 MMCMD from volcanic reservoirs in 2002 and since then exploration and development of the deep volcanic gas pools began in Daqing oil complex.The Xushen gas field has become the largest gas field discovered in the eastern onland China,with gas reserves accounting for 89.9% of the total in the study area.However,description of the volcanic reservoirs is the main bottleneck restraining exploration and development of deep gas in this area.This paper introduces a set of techniques for volcanic reservoir description,such as lithologic and lithofacies description of volcanic rocks,logging lithologic identification of volcanic rocks and seismic recognition of volcanic rock mass.These techniques provide a solid foundation for highly efficient development of the volcanic gas pools in Xushen gas field and fill the gap in comprehensive reservoir description of volcanic gas reservoirs in China.
