立陡状金属矿随机介质地震正演模拟研究

地震勘探对于陡倾角地层探测效果通常不好,但有很多金属矿成高陡或立陡产状.金属矿成层性不好,岩性变化大,矿体内部具有一定的随机特征.针对这个特点,建立一个垂直和水平构造的矿体模型,在均匀介质模型的基础上加入随机参数形成随机介质模型.经过对方差大小的试验,发现当矿体方差远大于围岩方差时,矿体的反射和绕射非常明显.所以在符合...

The study of random media seismic forward modeling of steep metal ore

The seismic exploration effect is usually bad for the detection of steep formation, but many metal ores are steep slope attitude. The deposit strata is not layered, lithology changes largely, and the inner of orebody appears some random characteristics. For this feature, we set up a vertical and horizontal structure of the orebody model, based on the homogeneous medium model by adding random parameters. After many experiments of the variance, it is discovered that the orebody's reflection and diffraction ar...
