Fracture-cavity carbonate rock model, method for manufacturing same and application of fracture-cavity carbonate rock model
The invention discloses a fracture-cavity carbonate rock model, a method for manufacturing the same and application of the fracture-cavity carbonate rock model. The fracture-cavity carbonate rock model comprises aggregate, cavity simulation components and rock mass fracture simulation components. The aggregate comprises cement, quartz sand, barite powder and water, and a weight ratio of the cement to the quartz sand to the barite powder to the water is (2-3):(1.5-2.5):(0.5-1):(0.4-1); the cavity simulation components are distributed in the aggregate; the rock mass fracture simulation components are distributed in the aggregate. The method includes filling a mold with the aggregate, the cavity simulation components and the rock mass fracture simulation components according to distribution laws; allowing the mold to stand still to sufficiently carry out physical and chemical reaction on the aggregate; detaching the mold to obtain the fracture-cavity carbonate rock model. The model can be applied to corresponding acoustic and mechanical characteristic tests and experiments on fracture-cavity carbonate rock mass. The fracture-cavity carbonate rock model, the method and the application have the advantages that test errors due to uneven stress in loading procedures can be prevented when the fracture-cavity carbonate rock model is used for the corresponding acoustic and mechanical characteristic tests and experiments on the fracture-cavity carbonate rock mass, and accordingly the accuracy of experiment and test result analysis can be improved.
