Recently, the technical staff of the Heavy Oil Research Institute of Shengli Oilfield Petroleum Engineering Technology Research Institute implemented the new technology of carbon dioxide-assisted viscosity reduction combined flooding in Block 10-49 of Shangdian Oilfield
Thermal recovery is the mainstream process for heavy oil development in Shengli Oilfield, but for heavy oil reservoirs with sensitivity and high water cut after multiple rounds of huff and puff, the effect is not satisfactory
Block Shang 10-49 belongs to a water drive heavy oil reservoir.
