The Central West To Polymer Flooding Oil Well Group Different Injection Parameters Design Standards

Sa development zone since 2009 in the implementation of old oil fields in the second development project, the central western as the first implementation of secondary development project capacity building blocks, according to the ground, underground "the overall research, unified deployment, synchronized advancement, comprehensive, balanced and" the second development policy, formulate the development countermeasures. Deployed to tertiary oil recovery, oil, Portugal, the Portuguese "two series" three kinds of reservoir, high counter three sets of the infilled adjustment of reservoir development pattern, and compiled three sets of well pattern of reservoir engineering plan. Among them, the central west Portugal to tertiary oil reservoir engineering design of oil Wells 588 the total number of Wells, injection-production well spacing is 125 m, mining for the first time interval for Mr ? 10?? 10 second type reservoir.Central west to polymer flooding in the area of oil in the no.1,2,3,4, no. 312 and no.605, no.308 in the new injection in the new station, injection-production well spacing is 125 m.Midtown west to polymer flooding oil solution using indoor experiment and has to carry out the area of the east five second polymer injection block experience, take the whole optimization, the parameters of the molecular weight of personalized design, the injected alternating slug injection way of the displacement, the smallest scale personalized design injection parameter, maximize improve polymer flooding recovery efficiency.
