摘要
厚覆盖区地下地质模型所依靠的数据主要是地震和测井资料,但地震数据反映范围广而分辨率低,测井数据则分辨率高而反映范围小,如何有效地将两者组合利用,克服各自不足是论证的重点,说明了用数据树的形式组织所有井与地震地质等数据,并能同时生成和编辑多口井的合成地震记录,来确定不同井的深时关系,为把不同域的地震数据和测井数据融合显示建立基础,提供了实时修改子波的频率和相位来做合成记录的功能,也有反射系数与子波的分布褶积等最新的方法,以慢镜头的形式说明合成记录的形成过程。这些功能的应用,给用户确定正确的地下速度场提供了先进的手段,为地质模型建立提供了先进的方法。
The data of geological model in heavy overburden areas was dependant on seismic data and well logging data. Seismic data was characteristic of wide reflecting range and low resolution, well logging data was characteristic of high resolution and small reflecting range. The focal points of demonstration for the, paper were to combine the seismic data and well logging data effectively. In a form of data tree, the explanation organized the well logging and seismic data, generated and edited the synthetic notes of the wells to determine the when and deep relationship of different wells, set foundations for the integration and display of seisrric data and well logging data in different domains, provide foundation for making synthetic notes of modification of frequency and phase for real time wavelet that would be proved to be an advanced method for geological model building.
