Enhanced Oil Recovery of K Oilfield in Kazakhstan by Micro-unit Development Technology

摘要

K oilfield in Kazakhstan is a medium-high permeability sandstone reservoir which underwent 34 years of waterflood development and went into a later high water cut stage in current,intrabeded and interformational heterogeneity is strong,and the distribution rule of remaining oil is very complex.Though a considerable scale of reserves,there is a big difficult for the stable production and increasing production,and the development clue is urgently in need of transformation.
