Parameter determination method and device for isoparametric fracturing of shale oil and gas well

The invention relates to the technical field of petroleum fracturing engineering, and provides a method and device for determining parameters of shale oil and gas well isoparametric fracturing. The method comprises the steps that constant construction parameters of a target oil and gas well and comparison fracturing parameters corresponding to the target oil and gas well are obtained; generating target prepad fluid dosage, target sand-carrying fluid dosage, target displacing fluid dosage, target sand-carrying fluid viscosity, first target proppant equivalent concentration and second target proppant equivalent concentration according to the contrast fracturing parameters, and generating target fracturing parameters corresponding to the target oil and gas well in combination with constant construction parameters, the target sand-carrying fluid pump injection amount and the target displacing fluid pump injection amount of the target fracturing parameters in any construction section are the same and are kept unch
