Practical Adjustment of Stratum Series for S Oilfield

Abstract:

In S Development Area, the production targets of each well net went bad and had interleaved distributions with old well patterns. Meanwhile, polymer flooding well patterns made the conflict of cohesion and dynamic regulation outstanding. Especially, Bei block, first using infill drilling modification, however, had troubles in extra high water period, such as long section of perforation, obvious inconsistencies between formations and high water of layers, which brought difficulties to dynamically adjusting. We selected 1.30 km² west blocks in Bei block, made tests about sediment group restructuring to improve water flooding development effect, redistributed the series of strata and redistributed the flooding network according to the characteristics of development between the layers, combined comprehensive consideration with follow-up adjustment, such as primary network, injection production system and typed II reservoir the tertiary oil production, optimized the layers combination and well patterns arrangement, finally formed technical ideas of high water cut layers adjustment and well nets evolution.
