Embodiment 1
[0035] A method for determining the movable fluid space of a rock core, comprising the following steps,
[0036] 1) Drill core pillars with a diameter of 2.5cm and a length of not less than 3.0cm, cut the core section flat, and measure the porosity and gas permeability of the core after oil washing according to the requirements of GB / T 29172-2012 rate and pore volume Vp;
[0037] 2) Test the movable space of the core water: the core to be tested is evacuated and saturated with water and aged for more than 24 hours, and then loaded into the test process to test the movable space Vw of the core water;
[0038] 3) Test the movable space of the core oil: the core to be tested is evacuated and saturated with oil and aged for more than 24 hours, and then loaded into the test process to test the movable space Vo of the core oil;
[0039] 4) Calculate the movable water and oil saturation of the core respectively through the movable space Vw of the core water and the movable space Vo ...
Embodiment 2
[0043]On the basis of Example 1, the device used in the device for determining the movable fluid space of the rock core described in the present invention at least includes a high-pressure displacement pump 1, a simulated water container 2, a simulated oil container 3, a pressure gauge 5, and a core clamp Holder 7, oil-water separator 8 and ring pressure pump 9, the inlets of the simulated water container 2 and the simulated oil container 3 are connected to the high-pressure displacement pump 1, and the outlets of the simulated water container 2 and the simulated oil container 3 pass through The multi-way valve seat 6 is connected with the rock core holder 7, the pressure gauge 5 is installed on the multi-way valve seat 6, the ring pressure pump 9 is connected on the rock core holder 7, and the outlet of the rock core holder 7 is connected There is an oil-water separator 8. The inlet and outlet ends of the simulated water container 2 are respectively connected with a simulated...
