Analysis on the FRS^TM Fracture-Based Pre-Stack Seismic Azimuth Attributes of the Sand Bodies in Fuyang Oil Layer in Songliao Basin

Abstract:

The later-period structure of Fuyang oil layer is complex and its reservoir is mostly composed by the sand bodies of riverways. The oil and gas reservoir features obvious concealment, and also is difficult to identify. Therefore, in this study, the pre-stack seismic attributes of the sand bodies in riverways were identified using FRS^TM fracture software in the study area, and the study results of the pre-stack detection on anisotropy showed that the relationship between the anisotropic development zone and the sedimentary microfacies is close and also they are affected by the fracture system. After a comprehensive analysis, it can be judged that the reliability of the anisotropic development features with fully-contained fluid or better physical properties after a pre-stack anisotropy analysis is very high, can objectively reflect the space distribution characteristics of the anisotropic strength at the targeted reservoir, and can plays an obvious effect on the areas of the complex later structure, and thin and complex sand bodies, so that the needs of oil fields exploration and development can be fulfilled.
