塔中顺西地区碳酸盐岩储层响应特征及识别预测方法研究

塔中顺西地区碳酸盐岩储层具有横向非均质性强、埋深大、地震资料分辨率低、成像精度不高等特点,临区碳酸盐岩储层预测技术方法借鉴效果不明显.针对本区储层发育特征,分析储层地震和属性响应特征,探索敏感属性融合技术划分有利储层发育带的方法,综合评价划带结果与实钻井具有较好的吻合性,取得了一定的应用效果.

The Response Characteristics of Carbonate Reservoirs and Identification and Prediction Methods in Shunxi Area of Tazhong

The carbonate reservoirs of Tazhong Shunxi area have characteristics with strong lateral heterogeneity and deeply buried. In addition, the resolution of seismic data is low and imaging accuracy is not high in this district. For these reasons, the application effect in Shunxi with carbonate reservoir prediction technique and method of pro- visional regional is not obvious. The result summarizes seismic and attributes response characteristics of carbonate reservoir, and investigates the method to divide favorable zone of carbonate reservoir combined with sensitive attrib- ute fusion. The predicted results are basically consistent with the actual data. It has some reference value in reser- voir prediction of this and other similar background reservoir prediction.
