摘要
Seismic sub-volume coherence and image synthesis technology thinks 3-D seismic sub-volume data of any size as the basic computational unit.This technology characterizes the change of geophysical parameters between sub-volumes by multi-operator method.It achieves high-resolution and multi-information detection of the correlation among seismic attributes,dip and azimuth information and has the characteristic of the small ave-rage effect.Therefore it is more sensitive to weak variations of the seismic data.It increases apparent resolution of the volume by displaying synthetically coherence,dip and azimuth attributes and describes more clearly distribution of small faults or cracks and characterizes quantitatively the border of complex geological anomalous body.The thesis predicts effectively the distribution of the cracks of the buried hill reservoirs in Block A and the width of the meandering rivers in Block B by this technology.
