摘要
葡北三断块油田位于大庆长垣沉积体南部,由于砂体窄小、分布零散、层间、层内、平面非均质性严重,稳油控水难度很大。在储层精细描述和剩余油研究的基础上,组合实施油水井双向调剖、长胶筒细分调整以及注水井酸化等多项措施,使得开发指标得以好转,改善了油田开发效果。该套技术对水下窄小砂体油田高含水后期的开发具有一定借鉴意义。
Pubei Ⅲ fault block located at the south ofDaqing Changyuan deposition body, because the sandbody issmall and narrow, distributed scattered, interlayer, innerlayer and the plane anisotropism is serious, stabilizing oiloutput and controlling water content is very difficult. Basedon reservoir fine description and residual oil research, wecombined and implemented oil and water well bidirectionalprofile modification, long packer subdivide adjustment andwater injection well acidification and many other measures,which make the development target better, improved the oil-field development effect. This technology has providedreference for under water narrow and small sand body highwatery period development.
