Resarch and Application of Injection－production Pressure System Adjustment in Block Wei 10

In view of the problems such as serious plane and in－terlayer inhomogeneity large difference of waterflooding status under－injection at high injection pressure and lacking of energy several measures are applied including fine reservoir characterizationuse of dense well spacing in microstructures and reinterpretation of log data and reservoir numerical modeling． The injection－production system is optimized development index improved and waterflooding control and producing reserves enlarged．
