【摘要】 火山岩储层识别和预测中最常用和有效的地震技术是正演模拟技术、地震属性分析技术、波阻抗反演技术和相干分析技术,并有各自的适用条件。对准噶尔盆地3个研究区的火山岩地震反射特征进行研究,建立准噶尔盆地4种火山岩地震相模式。通过准噶尔盆地火山岩油气藏的勘探实践,认为火山岩储层综合预测应该包含岩相预测、岩性预测、裂缝预测3个方面。更多还原

【Abstract】 Forward modeling,seismic attributes analysis,wave impedance inversion and coherence analysis are the most popular and useful techniques on identification and prediction of the volcanic rock reservoirs.Four patterns of volcanic rock seismic facies were built through the research on seismic reflection characters of volcanic rock reservoirs in three study areas of Junggar Basin.Combining with the exploration practices in Junggar Basin,a set of comprehensive exploration methods were summarized.It is pointed that volcanic rock reservoir interpretation should include facies prediction,lithology prediction and fracture forecast.更多还原
