The variation of low permeability formation's permeability due to explosive fracturing treatments is studied and a basis to realize and evaluate the effect of the explosive fracturing treatments by contrasting and analyzing the test results of the samples' permeability before and after the explosion experiment is provided. The test result shows that the permeability of those samples increases significantly due to the explosive fracture treatments; the permeability increases as the distance to the explosion center grows at first, then decreases and at last keeps a constant value, which is also much bigger than the initial permeability value.
