Abstract

The original oil in place suitable for chemical flooding in Shengli oilfield is 1.6 billion 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 technology has made great breakthroughs. A unique series of chemical flooding technologies has been developed and played a significant role in maintaining oil production in mature fields.
