AI Technical Summary
Existing technologies have low accuracy in paleogeographic reconstruction of reef-shoal carbonate rock strata, and direct analysis using conventional methods is prone to yielding erroneous results.
By acquiring basic data on reef-shoal facies carbonate rock strata, the top and bottom surfaces of the target layer are determined, a seismic facies model is established, the location of bioherms is identified, the current reef facies depth trend surface is fitted, the top and bottom surfaces are corrected, the compaction coefficient is determined, the stratum thickness and depth are obtained, and a paleogeographic reconstruction map is generated.
This method enables quantitative paleogeomorphological reconstruction of reef-shoal facies carbonate rock strata, improving the accuracy of the reconstruction and guiding the prediction of the distribution and development patterns of favorable reef-shoal facies reservoirs.
