Abstract: A calculation system for predicting a proppant embedding depth based on a shale softening effect is provided, including a sampling test terminal, a scheduling module, a monitoring module, and a calculation module, wherein the scheduling module, the monitoring module, and the calculation module are connected in communication, and the monitoring module is connected to an external operating system through a wireless network, wherein the external operating system is configured to perform a hydraulic fracturing operation and receive a first control signal and/or a second control signal from the monitoring module. The sampling test terminal is configured to test the samples and obtain test data. The scheduling module is configured to determine a target construction parameter.

Abstract: The present disclosure relates to a calculation method for predicting a proppant embedding depth based on a shale softening effect, including determining a spontaneous imbibition depth-soaking time curve; determining a Young’s modulus-soaking time curve of core surfaces; establishing a proppant embedding model containing a softened layer by a finite element method; conducting a numerical simulation to obtain an embedding volume-soaking time curve; and obtaining a calculation formula for a proppant embedding volume considering a softening effect.
