摘要
应用地震资料提取多种属性进行河道砂体预测,在目前的油气勘探中已得到越来越多的应用。它通过对地震数据进行复杂数学变换和计算而得出多种地震属性;通过对地震属性进行聚类分析,并结合平面、三维立体可视化,进行多方面综合分析研究。应用结果表明,地震属性预测砂体、油气效果良好。由此认为,借助多属性分析技术对河道砂体进行预测,可大大提高勘探精度,提高钻井成功率。
It has been increasingly used in oil and gas exploration to predict channel sands from various seismic attributes. These attributes may be derived from seismic data through complicated mathematical conversion and calculation. Comprehensive study has been conducted through cluster analysis of seismic attributes and plane and 3D visualization. Application result shows that it is a good way to predict sands, oil and gas by seismic attributes. Therefore, with the help of multi - attribute analysis technique to predict channel sands, exploration accuracy and drilling success ratio can be greatly improved.
