Summary: | The invention belongs to the technical field of oil and gas resource exploitation and relates to a device and a method for evaluating affinity of a carbon dioxide-philic proppant to a carbon dioxide-based fracturing fluid. The device comprises a carbon dioxide pressurization system, a carbon dioxide-based fracturing fluid preparation system, a carbon dioxide-philic proppant repeated sedimentation system and a data acquisition and control system. According to the device, a carbon dioxide-based fracturing fluid system with corresponding performance can be constructed according to experimental requirements, repeated settling velocity of the carbon dioxide-philic propping agent in the carbon dioxide-based fracturing fluid is measured, and affinity of different types of carbon dioxide-philic propping agents and the carbon dioxide-based fracturing fluid with different characteristics is preliminarily represented; on the basis, the change relation of the repeated settling velocity along with the contact time of the |
