摘要

应用地震储层学的理论、方法和技术对准噶尔盆地西北缘乌夏地区二叠系火山岩进行了研究。首先,明确了此类火山岩(熔结角砾凝灰岩)是裂隙式火山喷发的产物,其分布主要受早期火山口和火山喷发前古地貌的控制,储集空间以气孔为主:其次.采用本征值相干分析和古地貌恢复技术明确了火山口及喷发前古地貌特征:最后,综合利用测井、物探技术,对火山岩的有利岩性进行预测,形成了裂隙式喷发火山岩储层综合预测技术,并取得了较好的应用效果。

Abstract

Based on th e theory and technology of seismic reservoir,the Permian volcanic reservoir in Wuxia area in northwestern margin ofJunggar Basin is researched.The result shows that the volcanic rock(lava tuff breccia)is resulted from the fissure volcanic eruption,the distribution is mainly controlled by the early crater and the paleogeomorphology before volcanic eruption,and the reservoir space is mainly air hole.By using the technology of the coherence analysis and the  paleogeomorphology recovery,the characteristics of the crater and paleogeomorphology before volcanic eruption are identified.The technology of logging and geophysics are applied to predict the favorable lithologies,the forecasting technique for fissure volcanic reservoir is formed and good results have been achieved.
