Embodiment Construction
[0034] Such as Figure 1-Figure 3 As shown, a method for analyzing the opening field and seepage conditions of rock fractures under different pressures, the method includes the following steps:
[0035] Step 1: Select the required type of rock and split the rock to obtain a split sample 1;
[0036] Step 2: Cut the split sample 1 into a rectangular parallelepiped sample of appropriate size according to the crack direction;
[0037] Step 3: Separate the cuboid sample by extension cracks and divide it into two rock samples, which are marked as sample A and sample B;
[0038] Step 4: Drop the filler (liquid silica gel) on the fracture surface 9 of the sample A, combine the sample A and the sample B into the whole rectangular sample 8, and mark the relative position of the combination to record (the relative position The record should be along the direction perpendicular to the fracture surface) to ensure that the relative position does not change when it is combined for multiple times;
