| 摘 要： | 由于塔里木盆地碳酸盐岩储层段地震资料低信噪比、低分辨率等因素的影响,造成了裂缝预测难度大,如何提高预测精度是长期以来的技术难题之一。以解释性处理的三维地震数据为平台,通过大量预测参数实验并结合钻井资料、构造地质分析,形成了提高碳酸盐岩储层小断裂及微裂缝预测精度的一套系统、有效的技术系列,根据勘探开发精度要求的不同,采用相干、曲率、蚂蚁体等属性进行单一的或综合的叠后裂缝预测。此技术系列在塔中碳酸盐岩储层勘探开发中有效地指导了高产井点的优选,尤其是水平井的钻探,应用效果明显。

| Abstract: | It is difficult to predict fractures in carbonate reservoirs of Tarim Basin, because of the low S/N ratio and low resolution of seismic data and other factors. How to improve prediction accuracy is one of the technical difficulties for a long term. On the basis of 3D seismic data for interpretative processing, though a large number of experiments and analysis about drilling data and tectonic geology, we developed systematic and efficient techniques for enhancing the prediction accuracy of small faults and micro fractures of carbonate reservoirs. According to different exploration and development accuracy requirements, we adopted such attributes of coherence, curvature, and ant tracking for single or comprehensive poststack fracture prediction. The systematic techniques effectively guided high-yield wells selection in Tazhong carbonate reservoir exploration and development, especially drilling exploration of horizontal wells. They were applied well. |
