Sâ…¡1-9 Two Kinds Of Oil Layer Polymer Flooding Technical Study

Transition zone in the eastern mountainous area of northern Mid-Saertu Saertu oil reservoir put into development in 1964, with the deepening of the development by water flooding, remaining oil distribution is complex, rising, interlayer contradiction between Wells,in view of the problems existing in the development, according to the actual circumstance of oil layer, tertiary oil recovery will be taken to improve oil displacement efficiency, enlarge sweep volume, improve the ultimate recovery oil layer. Portugal’s a group of major reservoir using 250 m five point area of well pattern, the end of tertiary oil recovery, stepped into the stage of subsequent water flooding, according to the requirements of the capacity to connect,will conduct sal figure reservoir tertiary reservoir engineering research.In this paper, based on Saertu figure reservoir to further improve oil recovery technology is optimized design. On the basis of fine reservoir description, the north east one-two band sal figure oil reservoir characteristics, oil reserves, the system research of the current well pattern,through a variety of relative plan selection, optimization of the series of strata combination,deployed sal figure reservoir eor development pattern, and predict the development indexes for polymer flooding.
