地震反演技术在泌阳凹陷储层预测中的应用

Seismic Inversion Technique in Miyang Depression Reservoir Prediction

介绍了储层预测的基本原理和应用实例,应用JASON综合储层预测软件,将地震、地质、测井有机结合起来,互相补充、互相验证,对泌阳凹陷核桃园组地层进行了InverTrace、Invermode反演及岩性指示模拟,针对砂岩、泥岩和白云岩的波阻抗、孔隙度等属性进行统计和分析,预测了砂岩及白云岩的展布特征,并推测出有利的成藏区带。

First,basic theories and application examples of reservoir prediction have been introduced.Seismic survey,geologic survey and log are integrated,and complement and verify each other with JASON prediction software.InverTrace and Invermode inversion and lithology indication simulation have been done for Taoyuan formation in Miyang depression,wave impedance and porosity of sandstone,mudstone and dolomite have been calculated and analyzed.Finally,distribution of sandstone and dolomite and favorable area for reservoir formation are predicated.
