Additional oil recovery is obtained from a reservoir with a composition comprising at least a coupling solvent typically employed in waterborne coating compositions. Embodiments include recovering hydrocarbons using at least one coupling solvent, such as an oxygenated coupling solvent. The coupling solvent increases the mutual solubility with water at the injection temperature to facilitate the mixing and injection, particularly with an optional co-solvent. The coupling solvent helps mitigate formation plugging and improve performance when injected into a formation, as the solvent mixture moves from being miscible in the injection field water to being miscible in the reservoir oil, mobilizing the reservoir oil to increase oil recovery.
使用包含至少一种通常用于
水性涂料组合物中的偶联溶剂的组合物,可从储层中获得额外的石油采收率。具体做法包括使用至少一种偶联溶剂(如含氧偶联溶剂)回收碳氢化合物。偶联溶剂增加了在注入温度下与
水的互溶性,以促进混合和注入,特别是与可选的助溶剂一起。在注入地层时,偶联溶剂有助于减轻地层堵塞并提高性能,因为溶剂混合物从可混溶于注入油田的
水变为可混溶于储层油,从而调动储层油提高石油采收率。
