在Vp/Vs物性异常变化趋势分析的基础上,探索出了一种利用新的流体指示因子Rp-Rs预测储层含油气异常的新方法。实际应用效果表明,该方法可基本消除岩性异常对油气检测的影响,突出含油气异常。
Based on the analysis of the trend of Vp / Vs physical anomalies, a new method for predicting hydrocarbon anomalies in reservoirs using a new fluid indicator Rp-Rs was explored. The practical application results show that this method can basically eliminate the influence of lithologic anomalies on hydrocarbon detection and highlight the anomalies of oil and gas.
