低渗透油藏存在吸水能力差、高压欠注等问题。分析了纳米增注技术的应用现状与机理,认为其在疏通注水水流等方面效果显著,并能起到降压增注的作用,使高压欠注井能够满足配足要求,最终达到提高油田采收率的目的。 Low permeability reservoirs have poor water absorption, high pressure under-injection and other issues. The application status and mechanism of nano-injection technology are analyzed. It is considered that it has significant effect on water injection and flow diversion, and can play the role of anti-injection and anti-injection. The high pressure underfilled well can meet the requirements and finally improve the oil recovery The purpose of yield.
