Beschreibung
Zusammenfassung:	The invention relates to a drilling layer position identification method. The method comprises the following steps: obtaining derived parameters of a middle layer position point of a standard well and gamma-ray energy spectrum logging parameters of the standard well; calculating an error rate absolute value of the derived parameter of the sample well and the derived parameter of the standard well, and comparing the error rate absolute value with a preset value A; calculating an error rate absolute value of the gamma-ray energy spectrum logging parameter of the sample well and the gamma-ray energy spectrum logging parameter of the standard well, and comparing the error rate absolute value with a preset value B; the total number of the gamma-ray spectrum logging parameters and the derivation parameters is at least 14, when the absolute values of the error rates of at least 11 parameters of the gamma-ray spectrum logging parameters and the derivation parameters are all lower than 20%, it is affirmed that the hor
