摘要
随着地震勘探的不断发展,利用得到的地震资料来对储层中的流体进行识别,是一项重要储层预测内容。利用流体识别因子来实现对流体的识别是重要方法之一。首先对常用的现有的流体识别因子进行分析,然后从Gassmann公式出发,对地震资料的特点以及含不同流体介质的物理特性进行分析,提出了一个高灵敏度流体识别因子,最后以含气砂岩和含水砂岩为例,分析了不同流体识别因子的灵敏度。分析结果表明,高灵敏度流体识别因子对流体的识别较其他的流体识别因子有较高的灵敏度。
As the development of seismic exploration,it's very important to identify the fluid in the stratum by using seismic data.One of the most important ways to identify the fluid was to use fluid identification.The existed fluid identifying factor was analyzed first,based on Gassmann formula,the characters of seismic data and the physical characters of different fluid media were analyzed,a high sensitive fluid identifying factor was proposed.At last,by taking a sandstone containing water for example,it analyzes the sensitivity of the different fluid identifing factors.The result shows that the fluid identifying factors in this paper are more sensitive than others.
