Claim 8:
9. A consolidation and reconstruction simulation experiment evaluation method of a gas hydrate formation, using the consolidation and reconstruction simulation experiment system according to claim 2, comprising the following steps: S1: filling the cavity body with a material; and uniformly applying a layer of petroleum jelly on the pre-embedded pipe; delivering a lifting liquid by the lifting pump from the lifting liquid injection port to the lifting channel, and allowing the lifting liquid to enter the lifting liquid space through the lifting channel, such that the pre-embedded pipe is lifted; S2: after the pre-embedded pipe is lifted, delivering a consolidation liquid by the consolidation pump from the consolidation liquid injection port to the consolidation channel of the central oil pipe, and allowing the consolidation liquid to flow into the cavity body through the one-way valve to realize the cementing of the material in the cavity body;
S3: after the cementing is completed, delivering a fracturing liquid by the fracturing pump from the fracturing liquid injection port to the fracturing channel, and under an action of the sealing member, allowing the fracturing liquid to enter the cavity body through the perforations to realize the fracturing of the material in the cavity body; and
S4: after the fracturing is completed, conducting a corresponding hydrate test through the measurement points.
