| description | The invention provides a rock core measuring device and a rock core measuring method, and the rock core measuring device comprises a piston arranged in a rock core cylinder; the channel is formed in the piston and penetrates through the length direction of the piston; and the blocking piece is used for being arranged on the piston, and under the condition that the blocking piece is arranged on the piston, the channel is blocked by the blocking piece. According to the rock core measuring device, through the arrangement of the piston and the plugging piece, a rock core is firstly arranged in the rock core barrel, then the rock core barrel is filled with gel, and the piston is driven by displacement fluid to move towards the side where the rock core is located, so that the gel can permeate into the rock core; the core displacement pressure can be obtained based on the permeation amount of the gel and the conveying pressure of the displacement fluid. In the gel permeation process, the displacement fluid does not |
