摘要
尼日尔三角洲地区存在多个泥底辟和泥火山,在地震剖面上形成反射模糊区,泥火山对油气田储集层具有破坏作用。应用地震综合解释、海底地形图、时间切片和相干体切片等技术,总结了尼日尔三角洲泥底辟和泥火山的地震反射特征、形成机理以及对油气成藏的影响,为油田的储量评价奠定了基础。
There are a lot of mud diapirs and mud volcanoes in Niger delta,which appear in fuzzy zones in seismic section.The mud volcanoes are of destructive effect on the reservoir exploitation.Based on seismic stratigraphy,seismic interpretation,ocean floor relief map,time slice and coherent body slice,this paper summarizes the seismic response features,formation mechanism of mud diapers and mud volcanoes in Niger delta and their influences on hydrocarbon accumulation,which are significant to reserves evaluation in oil field.
