摘　　要：在国内石油储层中,低渗致密油藏面临“注入难,开采难”的问题,常规三次采油方法难以驱出地层原油,从而提出了渗吸采油这一方法理论。在广泛调研的基础上,分析了渗吸采油的基本原理,并且归纳了三种不同渗吸驱油材料(表面活性剂、纳米流体、聚合物)在渗吸中的驱油原理和应用。In China’s oil reservoirs,low-permeability tight oilfields face the challenges of difficult injection and difficult extraction.Conventional tertiary recovery methods often struggle to displace the formation oil,leading to the theoretical development of capillary pressure oil recovery.This paper conducts extensive research and analysis on the basic principles of capillary pressure oil recovery,summarizing the oil recovery principles and applications of three different materials used in capillary pressure:surfactants,nanofluids,and polymers.
