Title: Cold Production of Thin-bedded Heavy Oil Reservoir in Henan Oilfield
Abstract: Abstract The heavy oil reservoirs in Henan oilfield are mainly thin-bedded viscous and unconsolidated with viscous oil. Many of which are suitable for cold production. Lab experiments show that high permeability channels can be created in the reservoir when a large amount of sand is produced, and that the oil displacement efficiency is significantly improved in presence of dissolved gas. Field pilot shows that the fluid is produced in a foamy oil form with sand-cut of 2-20% (in volume) and oil production of 16-30t/d, which is over 10 and 5 times as much as that of conventional recovery and cyclic steam stimulation in the same reservoir respectively.
