Experimental study on water saturation effect on coal sample permeability under different effective stresses

Abstract: During the drainage and production of coalbed methane (CBM) wells, the Constant changes in stress and water saturation of reservoir restricts the dynamic change of the reservoir permeability. By carrying out stress sensitivity experiments with different water saturations in coal, the correlation between permeability and the coupling of effective stress and water saturation was analyzed. The water saturation sensitivity and stress sensitivity of reservoir were evaluated by the stress sensitivity index (S), perm… Show more

“…Scholars have conducted extensive research on the stress sensitivity characteristics of low-permeability tight reservoirs and their impact on gas well productivity [16][17][18][19][20]. As the water saturation of the reservoir gradually increases, the stress sensitivity of tight reservoirs becomes more significant [21][22][23][24]. If there is bound water in the rock pores, it will have a certain impact on the strength of argillaceous reservoirs.…”
