[0026] The present invention will be described in further detail below.
[0027] The present invention provides a method for dividing sedimentary strata. Using the reflection coefficient calculation method in the principle of seismic exploration, the seismic reflection coefficient curve is fitted from the logging curve, and the sedimentary strata are divided according to the characteristics of the reflection coefficient at different positions in the seismic reflection coefficient curve. The seismic reflection coefficient is the response characteristic of the developed sedimentary strata itself, and the judgment basis of the stratum division is based on the reflection coefficient, which is more real and accurate than artificial division. At the same time, due to the high vertical resolution of well logging curves, the anomalous features of the fitted seismic reflection coefficient curves can intuitively reflect the lithological changes of sedimentary strata, which can make up f...
