Abstract：We use seismic inversions provided by GeoEast on 3D seismic data in BD area, Erdos Basin for coal exploration and set up a prediction workflow for coal bed distribution and thickness. We perform post-stack BP neural network inversion based on genetic algorithm to predict coal bed distribution, and the pre-stack elastic parameter inversion to predict primary and shear wave velocity and then coal bed thickness. The prediction results coincide very well with well logs, and it can describe the coal distribution and coal bed thickness with other seismic information.
