Practice and Theory of Restructuring Water Flooding Series in Sabei Oilfield

Abstract:

In Sabei Development Area, with the developments of oilfield infill wells, the production targets of each set of well nets went bad and had interleaved distributions with old well patterns. At the same time, polymer flooding well patterns made the conflict of cohesion and dynamic regulation outstanding. Especially, Beierdong, which was the earliest block using infill drilling modification, got the good development effect at beginning, however, with the progress of oilfield development, there were some troubles in the development period with extra high water, such as long section of perforation, obvious inconsistencies between formations and high water of layers, which brought difficulties to dynamically adjusting. To fully exploit the remaining oil potential, this paper selected 1.30 km2 west blocks in Beierdong, made tests about sediment group restructuring to improve water flooding development effect, redistribute the series of strata and redistribute 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 type 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.
