Tight oil exploitation physical simulation test method

The invention relates to the technical field of petroleum exploitation, and in particular to a tight oil exploitation physical simulation test method. The method includes the following steps: (1) testing porosity and permeability of a rock core; (2) applying confining pressure to the rock core; (3) injecting a fluid body to the rock core so as to the inner pressure of the rock core to reach formation pressure; (4) supplementing the fluid body; (5) conducting linear reduction of system inner pressure so as to enable the fluid in the rock core to flow out continuously, and recording volume of the fluid body that flows out; (6) conducting a blank test; (7) and drawing the volume of the fluid body and system pressure, and obtaining an exploitation curve. The method of the invention realizes the physical simulation in the course of the tight oil exploitation, and has excellent repetition at each test point, small errors, and produces a test result that has a strong contrast to onsite production effects of the tigh
