Self-expansion packer wellbore simulation test device

The utility model discloses a self-expansion packer wellbore simulation test device, which comprises a wellbore hole simulator and a self-expansion packer. The inner wall of the wellbore hole simulator is adhered to a circle of cement layer, and the self-expansion packer is arranged inside the cement layer; and the wellbore wall of the wellbore hole simulator is provided with a heating system, and the wellbore hole simulator is provided with a liquid intake and discharge system which is connected with an impacting system used for impacting the self-expansion packer. The test device provided by the utility model can be used for simulating underground irregular wellbores and parameters of oil deposit temperature, pressure and the like, objectively reflecting the expansion property and pressure difference resistance of the self-expansion packer, thereby providing theoretical data support for the design improvement and field tests of the self-expansion packer.
