Abstract:
An experimental method for indoor real-time dynamic monitoring of a hydraulic fracture width, comprising the steps of: test piece preparation: assembling a prefabricating mold and fixing a fiber grating therein; mounting a simulated wellbore in the prefabricating mold, pouring agitated cement mortar into the prefabricating mold, and the cement mortar is solidified to form a test piece; mounting the test piece into a confining pressure chamber of a true triaxial hydraulic fracturing simulation device, connecting a liquid injection line to the true triaxial hydraulic fracturing simulation device, and connecting the fiber grating to a modem that is connected to a computer; hydraulic fracture width monitoring test: injecting liquid into the confining pressure chamber of the true triaxial hydraulic fracturing simulation device through the liquid injection line to apply three-direction confining pressures to the test piece, injecting liquid into the simulated wellbore, and starting the fiber grating and the modem to dynamically monitor the hydraulic fracture width in the test piece; and when a hydraulic fracture inside the test piece reaches an outer surface of the test piece, ending the test.

Claim (Index 6):
The experimental method for indoor real-time dynamic monitoring of a hydraulic fracture width according to  claim 1 , wherein in the step c), during application of the three-direction confining pressures to the test piece in three directions, a minimum main stress is applied to the test piece in a length direction of an intermediate section of the fiber grating, while an intermediate main stress and a maximum main stress are applied to the test piece in the other two directions perpendicular to the intermediate section; during a fracturing test, a hydraulic fracture inside the test piece is extended in a direction perpendicular to the intermediate section of the fiber grating; wherein the minimum main stress, the intermediate main stress, and the maximum main stress are increased sequentially.
