木147断块加密调整可行性研究及效果评价

木 1 4 7断块近几年含水上升过快 ,井况变差 ,平面、层间、层内矛盾突出 ,产量逐年下滑。为了挖掘断块的潜力 ,1 998年在精细油藏研究和动态资料分析的基础上 ,探讨了断块油层水淹规律及剩余油分布规律 ;找出了剩余油分布的有利区块和层位 ;用多种油藏工程方法对断块加密调整可行性进行了论证 ,并在此基础上于 1 999年对区块实施加密调整 ,取得了较好的效果

Feasibility study and effect evaluation on infill adjustment in Mu 147 fault block.

In recent years, water cut increment is too rapid, borehole condition is turning bad, the contradictions of the areal, within one formation as well as between different layers are obvious and the production reduces year by year in Mu 147 fault block. In order to tap the potential in this fault block, waterout and remaining oil distribution is discussed on the basis of detailed reservoir study and performance data analysis in 1998. The favorable blocks and horizons of remaining oil distribution are found. After the feasibility of adjustment in the block is proved by many methods on reservoir engineering, the infill adjustment was performed in 1999 and got good effect.
