摘要：On the basis of high-resolution seismic data, a high-frequency framework was established for the H12 well area. Combined with drilling analysis and sedimentary facies research, we analyzed favorable lithological development areas. Interpretation of subdivision layers in favorable lithological development areas, optimization of target sand bodies, and multi-attribute analysis techniques, we accurately describe the distribution of lithological bodies. By using spectral decomposition technology to perform insider characterization of lithological bodies, and combine with actual drilling to predict the distribution of effective reservoirs, we have summarized a set of effective methods for identifying such lithological traps.
