CT digital core-based microscopic displacement experiment system and microscopic displacement experiment method

摘要

A CT digital core-based microscopic displacement experiment system comprises a core gripper (4) and a microscopic displacement device. The core gripper (4) comprises an inlet end (4-1), an outlet end (4-2), a core area, and a housing. The housing is made of a polyetheretherketone (PEEK) material. The microscopic displacement device comprises an oil-phase intermediate container (2) and an aqueous-phase intermediate container (3) that are parallel, and comprises an advection pump (1) used for driving the oil-phase intermediate container (2) and the aqueous-phase intermediate container (3). Liquid discharge ends of the oil-phase intermediate container (2) and the aqueous-phase intermediate container (3) are each connected to the inlet end (4-1) of the core gripper (4). The core gripper (4) pressurizes a core gripped in the core gripper (4) by means of a hand pump (5). The outlet end (4-2) of the core gripper (4) is provided with a measurement bottle (7). The system is applicable to a small-capacity and small-scale microscopic displacement experiment, and the comprised technical device has a higher operation precision and a higher measurement precision compared with a conventional displacement experiment device.
