【摘要】 南二、三区西块面积井网1964年投产,1990年进行了一次加密调整,2000年进行了二次加密调整。区块加密调整后,增加了可采储量,薄差油层的动用状况得到改善,取得了较好的油田开发效果。随着开采时间的延长,近些年来尽管通过注采系统调整及注水综合调整等手段恢复地层压力,但目前区块地层压力水平仍然比较低,是萨南油田主要的低压区块。针对区块地层压力较低的实际情况,为合理恢复地层压力,改善区块开发效果,在南二、三区西块面积井网开辟一个低压区块综合治理试验区,通过精细地质解剖,分析落实区块低压成因和存在问题,结合区块开发实际,开展南二、三区西块低压区块综合治理。通过精细地质解剖,分析落实区块低压成因,综合评价注采适应性以及地层压力系统,通过油水井补孔、井网综合利用及注水方案调整等综合手段来恢复地层压力,探索区块合理注采比与地层压力恢复速度,以达到改善区块开发效果的目的。更多还原

【Abstract】 South two or three block area, West production well network in 1964, 1990, conducted an infilling, in 2000 a secondary infilling. Block cipher adjustments, an increase of recoverable reserves, the use of thin and poor reservoir conditions improved, oil field development has achieved good results. With the exploitation of time, in recent years despite the adoption of adjustment and water injection systems integrated adjustment means to restore reservoir pressure, but the level of block is still relatively low formation pressure is low Sanan major oil block. Formation pressure for the lower block the actual situation in a reasonable recovery for the formation pressure, improve the effect of block development in the South two or three block area, West to open a low-voltage block Well comprehensive test area, dissected by fine geological analysis implementation of the block causes and problems of low pressure, combined with block development of practical, South-II, III Block, West Block comprehensive low.Through detailed geologic anatomy, causes of the implementation of low-voltage block, adaptation and evaluation of formation pressure injection system, make holes through the oil wells, water injection well network utilization and comprehensive means of adjustment programs to restore the formation pressure, and explore reasonable injection block mining recovery rate than the formation pressure and to achieve the purpose of improving the effect of block development.更多还原
