塔中地区碳酸盐岩储层综合预测技术分析

Prediction technique of carbonate reservoir in Tazhong area

以碳酸盐岩地震储层学的理论方法为指导,针对碳酸盐岩储层横向变化快、非均质性强、成藏条件复杂等特点,并以碳酸盐岩储层地球物理响应特征为基础,在实际应用中形成了古地貌恢复、地震属性综合分析、三维地震相干体分析、频谱分解、叠前和叠后裂缝预测、岩石物理分析、三维可视化等一套针对碳酸盐岩储层的综合预测技术。该技术有效地指导了塔里木盆地碳酸盐岩油气藏的勘探,大力推动了碳酸盐岩地震储层学的深入发展,且在实际应用中取得了良好效果。

Carbonate reservoir is characterized by rapid lateral variation, strong heterogeneity and complex accumulation conditions. Under the guidance of the theory of carbonate seismic reservoir, and based on the geophysical response characteristics of carbonate reservoir, a set of comprehensive prediction techniques for carbonate reservoir is formed, such as paleogeomorphology recovery, seismic attributes analysis, 3D seismic coherence cube analysis, spectral decomposition, pre-stack and post-stack fracture prediction, rock physics analysis and 3D visualization. These techniques guide the exploration of carbonate reservoir in Tarim Basin and promote the development of carbonate seismic reservoir, and good result is achieved in the practical application.
