| 摘 要： | 岩石物理学研究中Gassmann方程被广泛应用于预测岩石中的地震波速度,由于输入的基质矿物体积模量参数不准确,极大的影响预测结果的可靠性,特别是复杂基质矿物组合的碳酸盐岩储层。因此本文结合Russell流体因子和Gassmann-Boit-Geertsma方程计算式,通过引入干岩石骨架泊松比,提出了一种基质矿物体积模量提取方法,能够自适应反演岩石基质矿物等效体积模量,提高流体影响预测的可靠性,通过实际资料流体替换验证,该方法的预测结果是可靠的,并且计算效率高、适应性强。

| Abstract: | Gassmann's equations are commonly used for predicting seismic wave velocity in rock physics research.However the input matrix mineral bulk modulus parameters are not accurate,which greatly influences the prediction reliability.In this paper,combining the Russell fluid factor with the Gassman-Biot-Geertsma equation and introducing the dry-rock Poisson's ratio,we propose an effective matrix mineral bulk modulus extraction method.This method can adaptively invert the equivalent matrix mineral bulk modulus to a... |
