摘要

从Gassmann方程出发,对地震资料的特点以及含不同流体介质的物理特性分析,提出了一个高灵敏度流体识别因子,并在Hiltermann总结的3类砂岩模型基础上对比分析了不同流体识别因子对流体识别的灵敏度。结果表明,高灵敏度流体识别因子对流体的识别较其他的识别因子具有更高的灵敏度。
As the quick development of seismic exploration,it is important to detect the fluid in the stratum by using seismic data.A way to identify the fluid is to use fluid detection factors.Those factors consist of velocities of P-wave and S-wave,media density,such as P-wave and S-wave impedances,velocity ratio of P-wave and S-wave,Poisson's ratio.Based on Gassmann formula,the characters of seismic data and the physical characters of different fluid media were analyzed,a high sensitive fluid detection factor(σFIFP)was proposed.Taking a sandstone model of Hiltermann for example and analyzing the sensitivity of the new fluid detection factor and the traditional factors to different fluids.The result shows that factor(σFIFP)is more sensitive to fluid than others.
