Analysis on the Applicability of the Post-Stack Seismic Attribute Recognition Method in the Sand Bodies of the River-Way of Fuyang Oil Layer

Abstract:

The later-period structure of Fuyang oil layer is very complex, and the reservoir mainly consists of river-way sand. The form of the reservoir is narrow and distributed differently, so it is very hard to identify. To accurately predict sand bodies, the sand bodies in the river way are comparatively studied using multiple post-stack seismic attributes, and finally a conclusion is made as follows: the reservoir interpretation technology based on frequency possesses a high spatial resolution and can test the spectrum lateral variation caused by different deposits, and then the plane distributions of the river-way and other deposits are described using equifrequent slices, and the combination characteristics of different deposit rhythmic layers are quantitatively analyzed, and also the thickness change of the river-way can be quantitatively analyzed under the ideal condition. Meanwhile, spectrum imaging is implemented using the tuning frequency of the different thickness of the sand bodies, and the reservoir is identified through the spatial changes of amplitude energy, facies values, and frequency attenuation attributes under the different chosen frequency, so that the spatial discontinuity of the deposits is effectively described. Therefore, it can meet the exploration and development needs of the oil field to a certain extent.
