The invention relates a three-dimensional simulation test device for oil extraction by injecting multielement hot fluid. The device consists of a multielement injection system, a model system, a data acquisition process and control system, and a production system, wherein a model body is fixed in a hyperbaric chamber; and the hyperbaric chamber is connected with the multielement injection system,the data acquisition process and control system, and the production system. As medium can be replaced by separately or simultaneously injecting the multielement hot fluid, and gases are taken as ambient pressure packing medium for the model, the work intensity during the processes of charging and discharging the ambient pressure packing medium is greatly lowered; and as the stimulated reservoir pressure reaches 20 MPa, and the simulated reservoir temperature reaches 350 DEG C, the real-time data acquisition and processing can be realized at the channel temperature of 460 DEG C and under the channel pressure of 50 MPa, and the data acquisition channel can be enlarged. The three-dimensional simulation test device for the oil extraction by injecting the multielement hot fluid has the advantages of fully-automated control of test processes, namely injection, extraction and strata pressure/temperature simulation, online three-dimensional graphic visual analysis and processing of test data,automatic collection of extraction liquid, and oil-water centrifugal separation.
