Experimental study on the influencing factors and pore production law of CO2 huff-and-puff in tight sandstone reservoirs

Abstract In order to determine the influence of different factors on the CO2 huff-and-puff displacement effect, a CO2 huff-and-puff experiment was carried out with Chang 6 tight sandstone samples in Ordos Basin as the research object. Combined with nuclear magnetic resonance technology, the influenc...
