Reasonable Bottom-Hole Pressure Analysis of Polymer Flooding Response Wells in Bohai S Oilfield
摘要
Abstract
Reservoir engineering and numerical simulation are used to research the reasonable bottom-hole pressure boundaries of oil wells during polymer flooding in Bohai S Oilfield. A formula to calculate the reasonable bottom-hole pressure boundaries of polymer flooding response wells is derived and verified by field data.Research indicates that the reasonable bottom-hole pressure boundary of polymer flooding response wells in inverted nine-spot pattern is mainly dependent on formation pressure,bottom-hole pressure during waterflooding,polymer injection timing and water-cut. A better polymer flooding performance can be gained for the well with bottom-hole pressure within reasonable pressure boundary.This research could provide a theoretical reference for the enhancement and populari-zation of polymer flooding.关键词
