摘要
基于叠前地震数据体中方位角和角道集的研究,从叠前开展油气储层各向异性分析和弹性波阻抗反演分析,为构造-岩性复合型油气藏储层尤其是碳酸盐岩储层的识别提供了一种全新的手段。以川东北宣汉地区飞仙关组碳酸盐岩油气藏储层为实例,开展了各向异性分析和弹性波阻抗反演,并对储层进行了综合评价研究。综合预测结果与钻探结果吻合,显示了该技术思路具有较好的应用前景。
Based on study on azimuth and angular trace assemblage in pre-stack seismic data body, hydrocarbon reservoir anisotropy analysis and elastic wave impedance inversion analysis are carried out from pre-stack, providing a thoroughly new approach to identification of structural-lithologic complex hydrocarbon reservoir, especially to carbonate reservoir. Taking the carbonate hydrocarbon reservoir in Feixianguan Formation in Xuanhan region in northeast Sichuan as an example, anisotropy analysis and elastic wave impedance inversion are carried out. Comprehensive evaluation study is also conducted to the reservoir. Comprehensive forecast result accords with the exploratory drilling result, showing a good application prospect of this technical concept.
