摘要
沈67块油藏由于受地层压实作用的影响,地层出砂严重,导致油水井管柱损坏严重,区块油水井开井率低,按目前井网难以达到预期的开发效果。针对油藏的开发特点,抓住有利调整时机,及时制订油藏二次开发方案,通过加密井网、重新划分层系、合理优化注采方案,较大幅度地提高油藏最终采收率。
As affected by formation compaction,reservoirs in Block Shen67 have serious problems of sand production and pipe string failure.The ratio of active wells is low.It is hard to attain anticipated development result with present pattern.Secondary development plan has been formulated according to reservoir development performance at proper time.Infilled well patterns,re-division of strata,injection-production strategy optimization are measures for improving ultimate recovery.
