Permeability detection device and method

The invention discloses a permeability detection device and method, and belongs to the technical field of petroleum drilling. According to the permeability detection device, a control module is connected with a test cabin module, and a measurement and analysis module is connected with the test cabin module and the control module; a reservoir rock core is stored in the test cabin module; the test cabin module rotates the reservoir rock core, and the control module controls environmental parameters of the test cabin module; and in the process that the control module injects a liquid into the test cabin module, the measurement and analysis module transmits an optical signal to the test cabin module, the optical signal is received by the measurement and analysis module after passing through the test cabin module, and the measurement and analysis module detects the permeability of the reservoir rock core according to the received optical signal. The provided device for detecting the permeability of the reservoir r
