Ma Xuejun, Li Zongjie. Fine seismic imaging technology for fractured-vuggy carbonate reservoirs in the Tahe oilfield[J]. 2008, 29(6): 764-768.DOI: 10.11743/ogg20080609.
A fine seismic imaging technology tailored to fit the characteristics of the fractured-vuggy carbonate reservoirs in the Tahe oilfield is developed.It consists of a series of techniques
including noise elimination
sur-face consistency processing
wavelet consistency processing
velocity analysis
3D DMO stacking
cascade migra-tion to image
and etc.It has been proven that a delicate combination of these techniques can yield fine images of the top erosional surface and inner karst of the Ordovician
thus improving oil well yield and providing technical support for a steady and fast development of the Tahe oilfield.
