摘要

在充分使用露头、钻井和地震资料的基础上,根据地震反射波的反射形态、反射结构、连续性、振幅和频率等特征,在阿瓦提断陷及邻区寒武系—下奥陶统识别出多种地震相单元。通过对地震相进行岩相-沉积相解释,建立地震相与沉积相的响应关系,认为在寒武纪—早奥陶世时期,阿瓦提断陷主要发育斜坡,蒸发台地,开阔台地,泄湖等多种沉积相类型。在下奥陶统碳酸盐岩台地内识别出2个坡折带以及4个可能的礁滩相带。
Utilizing seismic stratigraphy,principles and methods of sedimentology,based on outcrop,well data and seismic data,a variety of seismic facies units of Cambrian Series-Lower Ordovician Series are identified according to reflection shapes,reflection configuration,continuity,amplitude and frequency of the seismic reflection in await downfaulted basin and vicinity.On the basis of response relationship of sedimentary facies and seismic facies by lithic facies and sedimentary facies are interpreted from seismic data.Slope,evaporative platform,open platform,lagoon with the others from cambrian period-Lower Ordovician are identified.At the same time,two slope-break zones and four reef flat facies zones of Lower Ordovician Series are identified in carbonate platform,it will have important directive significance to look for reef flat reservoir.
