针对江汉盐湖盆地潜江组地层砂岩薄且横向变化大等特点,结合高分辨率三维地震资料,运用三维可视化与地震相分析技术,预测了广北河道砂体的展布特征。从广北河道砂体实际勘探效果着手,分析了三维可视化技术与地震相分析技术运用过程中取得成功的经验及解释陷阱。
In view of the characteristics of thin sandstone and large lateral variation of sandstones in Qianjiang Formation in Jianghan Salt Lake Basin, combined with high-resolution 3D seismic data, the distribution characteristics of sand bodies in the Guangbei River channel are predicted by 3D visualization and seismic facies analysis. Beginning with the actual exploration results of the Guangbei River sand body, the successful experience and explanation pitfalls in the application of 3D visualization technology and seismic facies analysis technology are analyzed.
