The invention relates to a high-resolution exploration method for high-porosity clastic rock sedimentary pile based on transverse wave velocity in geophysical exploration. The method adopts the following steps: the longitudinal wave velocity and the transverse wave velocity of a logged well are intersected with the natural gamma-logging curve of the logged well; the high natural gamma value section and the low natural gamma value section are determined; straight lines are distributed at the intersection point of the high natural gamma value section and the low natural gamma value section, and according to the intercept and the gradient of the straight lines and the intersection points and the inclination angles between the straight lines and the coordinate axis, the relational expression between the longitudinal wave velocity and the transverse wave velocity of the sandstone section and the relational expression between the longitudinal wave velocity and the transverse wave velocity of the mudstone section are obtained; the transverse wave velocity of the high and the low natural gamma value sections is calculated, and the initial model of the longitudinal wave velocity and the initial model of the transverse wave velocity of the seismic working area are built; and wave impedance inversion is performed to the seismic working area by using the initial model of the longitudinal wave velocity and the initial model of the transverse wave velocity and by adopting a conventional method, so as to obtain the ratio of the longitudinal wave velocity to the transverse wave velocity of the seismic working area and to divide the lithologic characters.
