摘要
针对张巨河油田地震综合解释中断层识别难、优势储层预测难的特点,利用构造导向滤波后的数据体提取相干属性,识别断层发育特征,准确刻画了断层形态;精细标定储层,沿层提取多种属性,通过优选建立对优势储层敏感的属性集;再利用模式识别的方法预测了优势储层分布范围。钻探结果与储层预测的吻合率达到80%以上。
The fault identification and dominant reservoir prediction in Zhangjuhe Oilfield are quite difficult in the seismic comprehensive interpretation.In order to accurately characterize faults,a coherent volume is extracted from datasets processed by structure-oriented filtering.Reservoirs are finely depicted and calibrated.After multi-attribute extraction along the horizon,the attributes sensitive to dominant reservoirs are proposed.Finally,the distribution of dominant reservoirs is predicted by the pattern recognition.Accorcling to the drilling results,the successful ratio of our prediction is above 80%.
