A study on the seepage characteristics and laws of nano-micron pore throat in a low permeable reservoir matrix is of great significance for promoting high efficacy of low permeable reservoirs. Threshold pressure gradient (TPG) is an essential factor to reflect the seepage law. Here. variation laws of TPG and its influencing factors of low reservoir fluid are analyzed systematically th... https://parisnaturalfoodes.shop/product-category/incense-patchouli/
