displacement ton
1.A unit for measuring the displacement of ships, equal to35 cubic feet, and supposed to equal the volume taken by a long ton of seawater.
2.Actually, Polymer flooding is the most favorable one of EOR technologies in Daqing oil field resulted from successes in both technique and economy through pilot, industrial and business tests because of oil production of 120-150t of a ton of polymer or that of 10%-12%OOIP of oil recovery. The HPAM displacement mechanism is thought traditionally as to increase brine viscosity, to improve mobility control ratio, to decrease brine permeability so as to improve sweep efficiency but displacement efficiency.
