The invention relates to a
diagenesis simulation experimental apparatus and method. The
diagenesis simulation experimental apparatus comprises a
rock core clamping mechanism, a heating mechanism, a gas
porosity and permeability measurement process, a
liquid injection and liquid permeability test process, an automatic continuous outlet-fluid metering and sampling mechanism, a burden pressure boost control mechanism, a fluid
physical property detection mechanism and a
data acquisition-calculation and
automatic control mechanism, wherein, the inlet and outlet of the
rock core clamping mechanism are respectively connected with the gas
porosity and permeability measurement process and the
liquid injection and liquid permeability test process; the heating mechanism is sheathed at the periphery of the
rock core clamping mechanism, and the burden
pressure injection port of the rock core clamping mechanism is connected with the burden pressure boost control mechanism; the outlet of the
liquid injection and liquid permeability test process is connected on the automatic continuous outlet-fluid metering and sampling mechanism; the fluid
physical property detection mechanism detects a fluid sample of the automatic continuous outlet-fluid metering and sampling mechanism; and the
data acquisition-calculation and
automatic control mechanism acquires, records, stores and calculates temperature, pressure and flow rate in an experiment and meanwhile controls operation of the corresponding
solenoid valve and the automatic continuous outlet-fluid metering and sampling mechanism according to the experimental status.
