塔里木盆地顺北地区断溶体地震反射特征与识别
|
摘要
断溶体为塔里木盆地奥陶系一种重要的碳酸盐岩储集体,是油气勘探开发的重要目标之一。根据断溶体形成机理,结合实际岩石物理参数,设计断溶体正演模型,通过正演模拟得到断溶体地震反射特征。正演结果表明,断溶体以大型走滑断裂为核心,形成"花束"状地震反射;大型走滑断裂处同相轴"错断",断溶体缝洞型储层表现为单个"串珠"状反射或强、弱"串珠"反射群等特征。正演模拟结果与实际地震资料吻合较好,证明了设计的断溶体模型较为可靠,可以指导地震剖面上断溶体的识别。
The fault-karst reservoir is a kind of the Ordovician carbonate reservoirs in the Tarim Basin,which is also one of the important targets for the hydrocarbon exploration and development.According to the formation mechanism of fault-karst reservoir combined with real petrophysical parameters,a seismic model of faultkarst reservoir is built,and seismic reflection characteristics of fault-karst reservoir are obtained with seismic forward modeling.The seismic modeling results show that the fault-karst reservoir is centered on large-scale strike-slip faults,forming a bouquet-like seismic reflection.The large-scale strike-slip faults show faultedfracture on seismic events.Fault-karst fracture-cavity reservoirs show single bead-like reflection,strong or weak bead-like reflection groups.The seismic modeling results agree well with seismic data,which proves that the built fault-karst reservoir model is reliable and can help the identification of fault-karst reservoirs on seismic sections.
