Embodiment Construction
[0017] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0018] Such as figure 1 The one shown for measuring CO 2 The experimental device for the diffusion coefficient in the oil reservoir includes a constant temperature box 1, which has the functions of constant temperature, heat preservation and temperature record collection. The mineralized water tank 2, the crude oil tank 3, and the CO2 are vertically arranged in the constant temperature box 1. 2 Gas tank 6, gas chamber 4 and simulated oil reservoir chamber 5, the gas chamber 4 and oil reservoir chamber 5 are equal in volume; a first plunger pump 8, a second plunger pump 7, a CO 2 Gas cylinder 10 and vacuum pump 9.
[0019] The first plunger pump 8 is connect...
