DEVICE AND METHOD FOR DIFFUSION OF ROCK AND DIFFUSION TESTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a diffusion testing device and a diffusion testing method of a rock using a rock testing piece easily formed.;SOLUTION: A diffusion testing device of a rock includes: a high concentration cell R1 incorporated with a solution containing a tracer in high concentration; a low concentration cell R2 incorporated with the solution containing the tracer in low concentration or the solution not containing the tracer; a rock testing piece 16 provided between the high concentration cell R1 and the low concentration cell R2; and a testing vessel 18 incorporated with these elements. A diffusion testing device 100 measures an effective diffusion coefficient of the rock. The testing vessel 18 is a bottomed and topped cylindrical vessel. The rock testing piece 16 is a cylindrical testing piece coaxially fixed in an inner part of this testing vessel 18. Either one of the regions among the cylindrical outside regions surrounded by the inside region of the rock testing piece 16 and the outer wall of the rock testing piece 16 and the inner wall of the testing vessel 18 is the high concentration cell R1 and the other region is the low concentration cell R2.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
