应用地震属性技术预测A地区储层

Prediction of reservoirs in A region with seismic attribute technique.

随着地震属性技术的不断发展 ,地震属性技术在储层预测工作中发挥着越来越大的作用。地震属性技术对储层的预测主要是利用储层物性和充填在其中的流体性质的空间变化 ,造成地震反射速度、振幅、频率等一系列基于几何的、运动学的、动力学的地震属性的变化。通过分析属性参数的纵横向变化 ,从而确定储层的分布范围和储层特性。主要以A地区为例 ,根据该地区含气储层具有的低速、低密度的特征 ,结合地球物理模型研究结果 ,综合利用多种地震属性技术 ,预测该区有利含气储层 ,取得了较好的效果。

With its progress, the seismic attribute technique is now playing more and more important role in the reservoir prediction. The prediction of reservoirs with seismic attribute technique is based on the fact that the spatial variations of reservoir petrophysics and properties of the infilled fluids can give rise to the variations of geometric, kinematic, and dynamic attributes such as velocity, amplitude, and frequency. The range and properties of a reservoir can be determined by analyzing the vertical and lateral variations of seismic attributes. By combining the available research results on geophysical models with different seismic attributes, the author has successfully predicted several favorable gas-bearing reservoirs in A region.
