摘　　要：准噶尔盆地滴南凸起石炭系火山岩气藏储层的储集空间包括基质孔隙和裂缝两部分。精细刻画小微断裂,对于预测裂缝型储层的分布有指导作用。利用构造导向滤波技术对地震数据进行处理,不仅可以提高剖面上断层的可识别性,识别小微断裂,还可以利用提取相干体属性对小微断裂进行精细刻画,分析裂缝的分布范围,指导火山岩天然气勘探。The reservoir space of Carboniferous volcanic gas reservoir in Dinan uplift of Junggar basin includes matrix pores and fractures.Fine depiction of small and micro fractures has a guiding role in predicting the distribution of fractured reservoirs.Using structure oriented filtering technology to process seismic data can not only improve the recognizability of faults on the profile and identify small and micro faults,but also extract coherence volume attributes to finely depict small and micro faults,analyze the distribution range of fractures,and guide volcanic naturalgas exploration.
