死油探测是油田注水中后期和强化采油期间决定是否应用下一步工艺技术的关键步骤,当从技术的角度确定是否继续注水或堵塞漏失层以解决高水浸问题时,必须清楚项目的总体经济状况,它决定了大多数方案的采用与否,不仅仅是考虑技术上的适用性。运用本文阐述的死油带探测工艺,通过应用喇曼光谱学可以精确地找到油藏中死油带或漏失层,这些层位的数量和深度可用于进一步设计注水或强化采油方案。由于可以使用微生物提高采收率的油藏很少,且没有商业方面的佐证,本文侧重于应用同样的工艺来直接探测石油,作为设计强化采油工艺的一个经济的辅助手段。该技术适用于各种井下条件和区域,在不久的将来必将成为具有商业应用价值的首选。
Dead-oil detection is a key step in deciding whether to apply the next process technology during late-stage and late-stage oilfield waterflooding. When determining whether to continue waterflooding or plugging the lost-bed to solve the high-level flooding problem from a technical point of view, it is important to understand the project’s overall economy It determines the adoption of most programs, not just technical applicability. Using the dead-zone detection technique described in this paper, the presence of dead zones or leaking zones in reservoirs can be precisely identified by applying Raman spectroscopy. These levels and depths can be used to further design waterflooding or enhanced oil recovery options. Since there are few reservoirs that can use micro-organisms to enhance oil recovery and there is no commercial evidence, this paper focuses on the direct detection of petroleum using the same process as an economic aid for designing enhanced oil recovery processes. The technology is suitable for a variety of downhole conditions and areas and will be the first choice of commercial value in the near future.
