Ignoring the gravity and capillary pressure, the multi-functional coreless displacement system can measure the relative permeability of oil and water, the recovery of water flooding and the electrical parameters of rocks by using two test methods: steady flow and unsteady flow. The system uses a modular structure and is equipped with application testing software based on Windows environment to realize system control, automatic measurement, data acquisition, processing, calculation and result output. The practical application shows that the instrument has the advantages of simple operation, multiple test methods, comparability of measured data, good representativeness and high reliability.
