Simulation evaluation device and simulation evaluation method for high-temperature high-partial-pressure carbon dioxide oil reservoir fluid

According to the simulation evaluation device and method for the high-temperature and high-partial-pressure carbon dioxide oil reservoir fluid, the color change of evaluation liquid can be monitored through a light guide-in device, a window and high-temperature-resistant mixed indicating liquid. Meanwhile, a small amount of liquid in the kettle is discharged from a needle valve at a liquid outlet, and the corrosion rate is calculated according to the measured total iron ion concentration in the liquid and the volume of the liquid in the kettle, so that the corrosivity of the liquid to be measured is evaluated. According to the device and the evaluation method, the continuous multi-point measurement of the pH value change and the corrosivity of the formation fluid is realized, and the problems that hanging pieces are frequently replaced and continuous investigation in an evaluation period cannot be realized in the conventional method for evaluating the corrosivity are solved. The method can be applied to oil r
