... accumulation in the tight glutenite reservoir (TGR) of the Lower Triassic Baikouquan Formation (T 1 b ) in the Mahu Sag is whether the oil can be laterally charged into the TRs. To analyze the lateral migration distances of oil in TRs and predict the favorable accumulation areas for oil, we have carried out...
