摘要
首先讨论了函数映射的数学模型, 然后介绍了基于函数映射模型的地层波阻抗参数估计方法。本方法充分利用了地震资料的横向连续性和测井资料的纵向高分辨率特性, 求取高分辨率的地层波阻抗参数, 为研究储层的岩性变化、估算储层参数、进行油藏描述提供重要的依据。通过实际数据试算, 表明该方法是可行的、有效的。
Abstract
The mathematical model of function mapping is discussed at first in this paper. Astratigraphic impedance parameter cotimation method based on the function mapping model is thenintroduced. This method combines the lateral continuity of seismic data with the vertical highresolution nature of well log data to produce high-resolution stratigraphic impedance parameters,which provides scientific basis for reservoir distribution study and oilfield exploration,development and production. Actual data trial computation shows that the method is feasible andeffective.
