低渗透油藏CO2驱SF6微量气体示踪实验研究
摘要
Abstract
The CO2 flooding technology is an effective method for enhanced oil recovery (EOR). Well-to-well tracer test is one important means to achieve the in-depth understanding on the characteristics of the displacement process for CO2 flooding. In this paper, the laboratory study of the SF6 gas tracer test in CO2 flooding is carried out for the natural low permeability core. The micro-size amount SF6 tracer injection method named as "Put in at atmospheric pressure and high-pressure injection" is originally designed, but also the gas chromatography detection method for SF6 tracer is established on the basis of high-sensitivity thermal conductivity detector. The results show that the SF6 tracer delivery process has the advantages of simplicity, controllable dosage strengths and tracer detection method also exhibit the advantages of simplicity, fast detection speed, high sensitivity and good precision.关键词
