| 摘 要： | 松辽盆地营城组火山岩广泛分布，构成数目众多、类型多样的火山机构，部分经后期构造变动埋藏于盆地深层并形成了大规模的火山岩储层.本文从多种地震技术手段中优选出常规地震剖面、构造趋势面和三维属性切片技术作为识别该区各类火山机构的方法，对徐家围子断陷营城组火山机构地震特征进行了系统分类.同时，结合徐家围子地区大量深层钻井资料分析，总结营城组5种火山机构类型与特征，并进一步研究了本区火山机构的分布规律及控制因素，发现区域大断裂控制着火山口和火山机构中心，火山口决定火山相带的展布，岩相控制火山岩的储层特征及空间分布.

| Abstract: | Volcanic rocks were extensively developed in Lower Cretaceous Yingcheng Formation of the Songliao Basin,forming numerous and multifarious edifices and volcanic structures,some of which were buried into deep basin by the tectonic changes of later period and then came into being a large-scale petroleum reservoirs.Among multifarious seismic technical means, the regular seismic profiles, tectonic trend surface and attribute slices were selected for distinguishing each type of volcanic edifices, and classified the edifices' seismic characteristics in Yingcheng Formation of the Xujiaweizi Fault-Depression.To synthesize the deep drilling data in the studied area,we summarized five types of edifices in Yingcheng Formation of the depression, and there were more studies on distributing regularities and controlling factors of edifices in the studied area.Generally, regional faults controlled the volcanic eruption, the vents and centers constrained distribution of the volcanic lithofacies belts, and then the lithofacies determined the characteristics and spatial spread of petroleum reservoirs. |
