The invention discloses a method for dynamically monitoring the state of a natural fracture under true triaxial hydraulic fracturing and related equipment, relates to the field of fracture slippage and opening monitoring, and mainly aims to solve the problem that the change rule of the fracture along with various experimental parameters in the experimental process cannot be monitored in real time in the prior art. The method comprises the steps that dynamic parameters of a sample under the hydraulic fracturing condition are obtained based on a monitoring system, and the sample is a tight reservoir simulation sample with fracture characteristics; and determining the crack opening and the crack slippage of the sample based on the dynamic parameters of the sample fed back by the monitoring system. The method is used for the dynamic monitoring process of the natural fracture state under true triaxial hydraulic fracturing.

The invention provides a natural fracture dynamic monitoring method under true triaxial hydraulic fracturing and related equipment. The method comprises the steps that on the basis of a hydraulic pressure test, dynamic parameters of a natural fracture sample under true triaxial hydraulic fracturing are obtained through an optical fiber sensor, and the sample comprises a shaft; and based on the dynamic parameters, crack slippage of the sample and deformation quantity of the shaft are determined. The influence of parameters such as natural fracture types, fracturing fluid displacement and fracture intersection angles on the deformation quantity of the shaft can be studied, so that quantitative evaluation is achieved, and technical support is provided for fracturing horizon optimization and fracturing construction site parameter optimization design. And meanwhile, the method has certain engineering significance for promoting the horizontal shaft damage prevention theory and technology and ...
