Claim 1:
2. The fast forward method for gamma-ray logging of highly-deviated and horizontal wells according to claim 1, wherein step S1 comprises the following steps:
S11: enabling a formation gamma-ray received by the detector to be equivalent to a formation gamma-ray intensity in a spherical space from an effective detection radius r0 of the gamma detector to obtain a gamma-ray flux of the formation received by the detector; and
S12: in an effective detection radius r0 space of the gamma detector, obtaining a gamma-ray contribution coefficient of a formation at a distance of z from the center of the detector along a well axis under the condition of the straight well.
