摘要
The core, debris and microscope structures of the volcanic rocks were observed, and the features of reservoir spaces were analyzed. The results show that the reservoir spaces contain three kinds of primary pores, secondary pores and facture-pores developed in the different places. The development of the reservoir spaces are dominated by lithology and lithofacies. The reservoirs in the air hole rhyolite of the upper lava subfacies, flood tuff in the heat clastic fluid explosive subfacies, breccia sandstone in the lava neck volcanic conduit subfacies are well developed.
