Lithologic and Storage-permeation Characteristics of Changshen 1 Volcanic Gas Reservoirs in Jilin
松辽盆地长岭断陷长深1号气田火山岩岩性及储渗特征研究

Multiple volcanic lithology is found in Changshen 1 volcanic gas reservoirs and different lithology has different pore\|fracture patterns in this area. The forming mechanism and evolution history of different pores and fractures is thoroughly analyzed using the core sample, casts thin slice and debris thin slice data. Accordingly, the relationship between lithology and pores as well as lithology and fractures are established and the pore\|fracture type and combination characteristics in different lithology have been clarified, too. The research is of great significance to the qualitative prediction of the reservoir physical property and to the quick determination of the advantageous reservoir through lithology identification.
