摘　　要：跃参1号区块奥陶系碳酸盐岩油藏埋深在6000m左右,具有较强的横向非均质性,储集空间类型主要为裂缝和孔洞。以碳酸盐岩地震储层学为指导,以碳酸盐岩地球物理响应特征为基础,综合运用地震振幅变化率、精细相干技术、趋势面分析技术、多属性叠合技术以及三维可视化技术,对区内碳酸盐岩储层进行了全面预测,并将本区碳酸盐岩划分为三个岩溶异常带。实钻效果显示跃参1号区块具良好的油气开发前景,证实了该套技术方法具有较高的实用性和预测精度。The depth of Ordovician carbonate reservoir in YC1 area is about 6000 m , which has strong lateral heterogeneity. The types of reservoir space are mainly cracks and holes. Based on carbonate seismic reservoir theory and carbonate geophysical response characteristics , by using the seismic amplitude variation , fine coherent technology , trend surface analysis technology , multiple attribute composite technology and 3D visualization technology , the YC1 area carbonate reservoir has been achieved comprehensive prediction.On the basis of this prediction , the YC1 area carbonate rock is divided into three karst abnormal band.Real drilling result shows that YC1 area with good prospects for oil and gas development.
