Experimental device for simulating heavy oil nitrogen injection assisted steam huff and puff

The invention provides an experimental device for simulating thickened oil nitrogen injection assisted steam huff and puff. The experimental device comprises a reaction kettle, the reaction kettle is provided with a reaction cavity, a first inlet-outlet and a second inlet-outlet, and the first inlet-outlet and the second inlet-outlet are both communicated with the reaction cavity; the steam generator is communicated with the reaction cavity through the first inlet and outlet so as to inject steam into the reaction cavity; the nitrogen storage device is communicated with the reaction cavity through the first inlet and outlet so as to inject nitrogen into the reaction cavity; the component analysis device is communicated with the reaction cavity through the second inlet and outlet, and the component analysis device is used for testing and analyzing components of gas and/or liquid in the reaction cavity. According to the technical scheme, the experimental device for simulating the thickened oil nitrogen injectio
