文摘

Migration in unsaturated unconventional gas reservoir samples was monitored by NMR. The aqueous phase volume in samples was kept constant in the migration. New parameters were extracted from T2 spectrum to characterize the migration. Migration from lager pore to smaller pores was observed and characterized. Characters and factor of migration in different samples were compared and analyzed.
