Study on surfactant flooding in low-permeability reservoirs of subnormal pressure
摘要
Abstract
Surfactant flooding is available in low‐permeability reservoirs ,but the study in these fields of subnormal pressure are rarely .This paper uses numerical simulation method to study the effects of key parameters on performance of surfactant flooding .The results show capillary number is the most sensitivity factor in normal pressure reservoirs ,and it decides the select and the research of surfactant .It also determines the effect of surfactant flooding . But in reservoirs of subnormal pressure ,the injection concentration is the most sensitivity factor ,other parameters like adsorption and viscosity affect the oil recovery are similar to that in reservoirs of normal pressure .This study can provide key references for surfactant flooding in low‐permeability reservoirs of subnormal pressure .关键词
