摘　　要：Biot理论将地下储层模拟为Biot介质 ,将储层参数与地震波传播有机的结合起来 ,更接近于地下的真实描述。基于Biot理论的储层参数处理为我们提供了更丰富的储层信息。以往利用地震资料求取储层参数 ,通常存在一些不足之处 ,如求取低频分量时 ,在有井的情况下 ,以井与井之间的低频分量的内插是一个难题 ,简单的线性内插只有在地层产状平缓变化时才能取得较好的效果。本次研究所采用的Biot方法 ,充分考虑了地震波在固液双相介质条件下传播的特殊性质 ,并对实际探区的有效厚度参数进行了预测 ,取得了令人满意的效果。以该方法在永乐油田东块储层地震方法研究中的成功应用 。According to Biot theory, the underground reservoir is simulated as Biot media. The reservoir parameters are combined with the propagation of seismic wave to be further like the real description under ground. The reservoir parameters processing based on Biot theory provides more abundant reservoir information for us. The former method of using seismic data to extract reservoir parameters usually exits some disadvantages. For example, when extracting low frequency component the interpolation of low frequency component between wells under the existence of wells is one difficult problem met by us. The better results of simple linear interpolation can be got only when the stratigraphic attitude changes flatly. The Biot method studied in this paper fully considered the special propagation features of seismic wave in liquid and solid two phased media. This method is applied to predict the effective thickness parameter of the exploration area and the results are satisfactory. This paper discusses the theory and the practice results of using Biot method to predict reservoir parameters based on the success application of this method in Dongkuai reservoir of Yongle oil field.
