Method and device for determining elasticity modulus of clay, electronic equipment and medium

The invention discloses a clay elastic modulus determination method and device, electronic equipment and a medium. The method comprises the following steps: determining a main mineral, and calculating the mixed modulus of a mineral matrix and the bulk modulus and density of a mixed fluid; performing fluid replacement on the mineral matrix mixed modulus to enable the rock to be in a water saturation state, calculating rock impedance through logging data under water saturation, and intersecting the rock impedance with the total porosity; simulating a bulk modulus and a shear modulus of the rock through a contact cementation model, and establishing a porosity-impedance cross plot; projecting the reservoir logging data points and the mudstone layer section data points into the porosity-impedance cross plot; and projecting the data points of the target layer section into the porosity-impedance cross plot, and determining the elastic modulus value of the clay of the layer section. The method can solve the problem o
