近年来,随着火山岩油气藏的不断发现,其储量越来越成为新的储量增长点,但火山岩作为一种特殊储集层,其研究难度和预测难度都较大。以准噶尔盆地五彩湾地区石炭系火山岩为例,依据已钻井火山岩岩性及岩性组合对应的地震响应特征,建立了火山岩相识别模式,总结了火山岩相的地震研究方法,预测了有利火山岩勘探相带,为该区及类似地区的火山岩岩相预测提供了可借鉴的方法。 In recent years, with the continuous discovery of volcanic reservoirs, its reserves are becoming more and more new reserves growth points. However, as a special reservoir, volcanic rocks are difficult to study and difficult to predict. Taking the Carboniferous volcanic rocks in Wucaiwan area of ​​Junggar Basin as an example, based on the seismic response characteristics of the lithologic and lithologic assemblages of drilled volcanic rocks, a volcanic facies identification model was established and the seismic research methods of volcanic facies were summarized. The favorable volcanic facies exploration facies It provides a reference for volcanic lithofacies prediction in this area and similar areas.
