Feasibility Study on Development of Low Permeability Reservoirs in Xianhe Oilfield with Short Well Spacing

Large producer - injection spacing, poor control of waterflooding and low oil recovery are the main factors influencing the development of Xianhe low permeability reservoir in Shengli oilfield. Based on analysis of the relation between well spacing density and control degree of water-flooding and oil recovery, a rational well spacing density is presented for development of Xianhe low permeability reservoir.
