基于SC-Gassmann模型的纵横波速度预测
Waves velocity prediction based on self-consistent model
摘要
Abstract
In this paper, the Gassmann theory, Biot theory and elastic wave theory are combined to quantitatively analyze the relationship between the physical parameters of the rock and the seismic dynamic parameters.The physical parameters of rocks are extracted from the actual well logging data.Based on the self-consistent model, the log data is used to predict the wave velocity.The elastic properties of rock with fluid and the waves velocity are calculated through the rock physical model, which provides a basis for reservoir prediction and fluid identification in this paper.The predicted results obtained by this method are in agreement with the log data.This is consistent with the actual geological conditions, which proves that the method is reliable and effective.关键词
