【摘要】 根据松辽盆地深层火山岩的地质和地球物理特征,在精细层位标定和解释的基础上,总结不同火山岩体在常规地震剖面的多种反射特征,建立火山岩体的地震相识别模式,同时采用地震属性分析技术直接识别和预测火山岩体的位置及分布范围。在重点研究的5个断陷中,综合识别出新火山岩体49个,取得了良好的应用效果。更多还原

【Abstract】 This paper summarized the geologic and geophysical characteristics of volcanic rocks in Songliao Basin.On the base of fine horizon calibration and interpretation,the seismic identification pattern of volcanic rock bodies was established.Seismic attribute analysis technique was used to directly determine the location and scope of volcanic rock bodies.49 volcanic rock bodies were newly delineated in 5 fault depressions.更多还原
