YH地区碳酸盐岩储层预测方法研究及应用

Research and application of carbonate reservoir prediction method in YH area

针对YH地区碳酸盐岩裂缝储层埋藏深、岩性复杂、地震响应不明显、非均质性强的特点,文章综合应用叠前地震资料裂缝预测、地震属性分析、阻抗变化率反演技术对YH地区碳酸盐岩储层进行了综合预测,同时总结出了一套适合于本地区的储层预测方法,该方法避免了常规储层预测在碳酸盐岩地区模型化过重的缺陷,提高了储层预测的精度。

The carbonate reservoirs in YH area are characterized by deep burial depth, complex lithology, unobvious seismic response and strong anisotropy. The techniques of fracture prediction, seismic attribute analysis and impedance inversion are applied to predict the carbonate reservoir. A set of reservoir prediction method suitable for this area is put forward, which could improve the precision of reservoir prediction.
