摘要
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.
