Parameter Design And Optimization Of Polymer Injection In G-N Oilfield

According to the requirements of G-N oilfield "twelfth five-year" development planning, exploring the oil field in determining phase to improve oil recovery technology is the core of the stable work. Neogene reservoir G-N oilfield production accounts for about 50% of the oil field production, now entering high water cut st age, need to change the structure of displacement, improve the develop ment effect, continue to m aintain the im portance of shallow reservoir producing oil in oil field yield components. As mature tertiary oil recovery technology, polymer flooding has been widely industrial application in daqing oilfield, shengli oilfield, provides the G-N oilfield eor t echnology can draw lessons from experience. Considering the tertiary complex fault block reservoir in G-N oilfield of the actual situation of promoting tertiary oil recove ry technology of polym er flooding should be on the prem ise of fully demonstrated the necessary pilot test, the necessary technology and experience, expand, polymer flooding for the future industrial ap plication provides tech nical reserves. The preferred good reservoir conditions, rich resources foundation of B district as the pilot test area.The purpose of this test is through the well pattern adjustment, interval recombination, screening with polymer flooding agent, plugging combination, optimize injection slug, work out suitable for high light north reservoir geologic characteristic of the polym er flooding technology, slow down production decline and im prove the development ef fect, improve recovery factor.By polymer flooding pilot test, to explore the upper tertiary m iddle and bottom water reservoir with complicated fault block si de to im prove oil recovery technology for determining development phase, for G-N oil field production and provide technical reserves.
