Method of Lithologic Trap Prediction and Its Application

Based on high-resolution seismic data,using well logging data, drilling data and seismic data, and using sedimentary micro-fa-cies.this paper establishes geological and seismic forward models for different kinds of sand bodies. And according to characteristics of seismic reflecting series, impedance from seismic inversion and other seismic attribute parameters, we determine the sand body variation and define its distribution in the study area. A set of lithologic trap identification technology for thin interbedded layers from this study is obtained. The good result from applying the method to real data from Gulong and Yingtai-Daan areas to the west of Daqing Pla-canticline is obtained.
