摘要
从岩石物理测试和数值模拟出发,塔东碳酸盐岩研究区优质储层和频率息息相关,利用射线域Zoeppritz方程,将频率因素引入AVO分析中,用频变AVO方法分析速度频散异常特征,从而预测优质含气白云岩储层。在塔东地区碳酸盐岩气藏的含气性检测中,取得了良好的应用效果。
In this paper,the high-quality reservoirs in the study area with closely relations to the frequency are observed based on petrophysical tests and numerical simulation.Using the ray domain Zoeppritz equation frequency factors are introduced into AVO analysis.The frequency-dependent AVO method is used to analyze the abnormal characteristics of velocity dispersion,and then to predict the high-quality gas-bearing dolomite reservoirs.Good application results have been obtained in the detection of gas content of carbonate rock gas reservoir in Tadong region.
