Synthetic seismograms were made using drilling, well logging data and seismic data to determine the top of the oil-bearing sandstones as a peak of strong amplitude reflection. Three-dimensional coherence analysis was used to explain the development and distribution of faults accurately. Accurately describe sand using bedding slices and 3D visualization techniques The logging data of the resistivity wave impedance inversion can improve the seismic resolution. On the basis of this, the horizontal variation of the morphology, thickness and physical properties of the single sand body is further described. Landing point, and at any time guide the horizontal well drilling, so that the first large-scale horizontal well drilling in the Bohai Sea was successful
