Chemical Flooding Applied in the Shengli Oilfield
The original oil in place suitable for chemical flooding in the Shengli oilfield is 16.05 × 108 ton.Though the resource is abundant, the oil recovery is poor due to rigorous reservoir conditions, including high temperature, high salinity, high divalent-cation content, high oil viscosity and severe heterogeneity.In an effort to counteract the rigorous reservoir conditions, polymer flooding technologies for class Ⅰ and Ⅱ reservoirs has been improved, and surfactant/polymer flooding has been implemented industrially.Heterogeneous combination flooding and foam flooding technologies have made great breakthroughs.A series of chemical flooding technologies have been developed, and these methods play a significant role in maintaining oil production in mature fields.
