火山岩相地震研究方法及应用
|
摘要
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,the reserves are more and more becoming new points of incremental reserves.However,as a kind of special reservoir,the volcanic reservoir is still difficult in study and in prediction.Taking the Carboniferous volcanic rocks in Wucaiwan area of Junggar basin as an example,the identification model for volcanic facies is developed,the seismic study method for it is presented and the favorable zones for volcanic reservoir prospecting are predicted,based on available volcanic lithology and lithologic assemblages as well as corresponding seismic responses,which provide a assistant and practicable method for prediction of volcanic facies in this and similar areas.
