准噶尔盆地北三台火山岩中的示底构造类同于碳酸盐岩发育的示底构造,主要发育于火山岩的气孔和自碎缝中,其下部主要为渗滤泥沉积,上部常为结晶的钠沸石或其他自生矿物,二者之间界面平直.火山岩示底构造的发现,对火山岩岩层的顶底识别、岩相划分及油气勘探具有重要意义.发育示底构造的岩层其物性相对较优、溶蚀孔发育,产能高,均为油层和含油水层.

The geopetal structures of volcanic rocks in Beisantai field of Junggar basin are similar to those of carbonate rocks,which are mainly found in volcanic gas pores and autoclase fissures.The bottom of them is dominated by filter mud deposit,the top of them by crystal sodalite and other authigenic minerals,with fiat interface.The discovery of volcanic geopetal structures is of important significance in identification of top and bottom of volcanic rocks,classification of lithologic facies and oil-gas exploration.It is concluded that the strata developed with geopetal structures have relatively premium quality,developed solution porosity,higher production rate as oil zone and oil-water bearing zone.
