The Study On The Change Regularity Of Development Indexes Of Second Type Reservoir With Polymer Flooding In Lamadian Oil Field

In 2003, Daqing oil field begin to polymer flooding in the second type reservoir,By the end of 2013,the number of the polymer flooding block of the second layers has reached24,oil-bearing area of 197.24 km2,geological reserves of 242.57 million tons,Oil and water Wells is a total of 8946,increased 20.7735 million tons of oil production.Although polymer flooding technology gradually become mature,the problem of polymer flooding development index prediction has been troubling us.The difference between second and main layer decided there would be a big different in polymer drive performance,therefore,Research on polymer flooding development index prediction methods was carried out by us。Based on geological characteristics of second type reservoir and polymer flooding,studied and analyzed the dynamic development indexes of three polymer blocks of second type reservoir of Lamadian oil field in Daqing, get the variation of injection pressure, inject and development differential pressure, water content, liquid production and other development index in the in polymer flooding, implemented the prediction of development indexes of second type reservoir with polymer flooding, provides theoretical basis and technical support for development the second type reservoir with polymer flooding in Daqing oil field.
