Embodiment 2
[0069] According to another embodiment of the true triaxial sand fracturing test method of the present invention, the true triaxial sand fracturing test machine used is the same as that of the first embodiment, the test procedure is the same as that of the first embodiment, and the test parameters are different . In this example, the total volume of the pre-fracturing fluid, sand-carrying fracturing fluid and replacement fracturing fluid injected into the downhole core is 800ml, of which the pre-fracturing fluid, sand-carrying fracturing fluid and replacement fracturing fluid The fluids are 40%, 50% and 10% of the total volume respectively, that is, the injected pre-fracturing fluid is 320ml, the sand-carrying fracturing fluid is 400ml, and the replacement fracturing fluid is 80ml.
Embodiment 3
[0071] According to another embodiment of the true triaxial sand fracturing test method of the present invention, the true triaxial sand fracturing test machine used is the same as that of the first embodiment, the test procedure is the same as that of the first embodiment, and the test parameters are different . In this example, the total volume of the pre-fracturing fluid, sand-carrying fracturing fluid and replacement fracturing fluid injected into the downhole core is 600ml, of which the pre-fracturing fluid, sand-carrying fracturing fluid and replacement fracturing fluid The fluids are 40%, 50% and 10% of the total volume respectively, that is, the injected pre-fracturing fluid is 240ml, the sand-carrying fracturing fluid is 300ml, and the replacement fracturing fluid is 60ml.
