| 摘 要： | 针对薄层砂体的地质和地震特征（单层厚度薄、岩性横向变化快），结合小波多分辨率分析理论和多方向分形分维理论，以预测薄层砂体的空间展布为目的，研究了不同尺度不同方向的分形分维计算方法来识别薄层砂体的纵横向边界，通过对比分析不同尺度不同方向的分形分维数，得到多尺度多方向的分形维数能更好地反映储层的空间展布，通过制怍地质模型，论证了方法的有效性和实用性，并将其应用到某油田，取得了较好的效果。

| Abstract: | Against the geological and seismic features of thin sandbody(thin single layer and sharp lateral variation of lithology), combined with wavelet multi-resolution analysis theory and multi-direction fractal dimension theory,aimed at predicting the space distribution of thin sandbody,this paper conducted research on variant resolution/direction fractal dimension calculation methods to identify longitudinal and lateral boundary of thin sandbody.Through comparing with variant resolution/direction fractal dimensi... |
