摘 要: 介绍一种向出水层注脱气原油的堵水工艺,主要是创造性地应用了油、气藏相对渗透率理论,探索出一种具有堵水施工简单、堵水剂可就地取材和堵水成本低等优点的能提高油田采收率的新工艺。设计了地面施工工艺、井桶注采管柱等,提出了当油井含水高时,向油井注入脱气原油,并采用同一管柱采油一体化注采工艺。该工艺可以解放中低渗透油层的生产能力,降低油田产水,提高油田的最终采收率。
关 键 词: 采矿工程;堵水;相对渗透率;采收率

Abstract: This paper introduces a water plugging process injecting degassed oil into water yielding layer, which creatively applies oil and gas reservoir relative permeability theory. This approach is characterized by simple water-plugging constructions, easy access to water-plugging agents, and low water-plugging cost. This paper introduces a ground construction technique, injection-production pipe in the oil well and an integral injection-production technology that injecting degassed oil in the oil well when the water cut of the oil well is tall and producing oil by the same pipe line, During the mid-and-late oil developing period, this approach is adopted in water plugging and plays a great role in liberating the productivity of the mid-and-low permeability oil layer, decreasing water production in oil fields, and enhancing the final oil recovery in oil fields.
Key words: mining engineering; water plugging; relative permeability; oil recovery
