ERROR ANALYSIS OF TRANSIENT METHOD FOR ROCK PERMEABILITY MEASUREMENT

ABSTRACT
In this paper, the permeability of sandstone, mudstone, gangue, and limestone under the condition of initial elastic deformation is obtained by transient method test. Mercury intrusion test is carried out on the four kinds of rock samples to obtain the initial permeability of the rock samples. The results show that the magnitude of permeability obtained by mercury intrusion test and transient method test is completely consistent. The measurement error is analyzed. The relative error of permeability in this paper is less than 6.0%. It can be showed that the use of transient method to measure the permeability of rock samples is reasonable and reliable.
