Clastic rock reservoir sweet spot area prediction method and device, medium and electronic equipment

The embodiment of the invention discloses a clastic rock reservoir sweet spot area prediction method and device, a medium and electronic equipment. The method comprises the following steps: calculating seismic lithology sensitive factors according to intercept information, gradient information and a rotation angle of seismic data; determining a density factor according to pre-obtained rock core and rock debris analysis test data and earthquake rock physical data; calculating a fluid factor by using the intercept information, the gradient information, the density factor and a predetermined rock longitudinal and transverse wave velocity ratio coefficient and Poisson's ratio; processing the seismic lithology sensitive factor, the density factor and the fluid factor by using a preset seismic inversion technology to obtain a seismic lithology sensitive factor data volume, a density factor data volume and a fluid factor data volume; and predicting the dessert area of the clastic rock reservoir according to the seis
