Abstract

Summary

Traditional shear-wave splitting analysis mainly focuses on velocity anisotropy, which is poorly understood in detecting oil/water. The main objective of this project is to evaluate the ability to discriminate oil and water from shear-wave splitting (SWS) amplitude. Anisotropic-viscoelastic model was established from Luojia area in Shengli oil field, fast and slow shear-wave were recorded using HTI viscoelastic equation. Both ratio and subtraction differences of SWS show the relation between SWS amplitude and fluid type. A detailed cross analyses were given to evaluate oil-waver boundary using SWS amplitude differences. The connecting-well seismic profiles suggest the possible use of SWS amplitude to discriminate between oil and water in fractured reservoirs.
