摘要：针对吉林油田低渗高温高盐的特点，开发出适合该类型油藏含有羟基、酰胺基的磺酸盐耐温耐盐型起泡
剂-YUDP。考察了起泡剂浓度、溶液矿化度、温度、pH、钙镁离子总含量、残余油饱和度对起泡剂起泡能力、
稳泡能力以及油水界面张力的影响。结果表明，YUDP 耐温（75 ℃）、耐盐（总离子质量浓度 31037.9 mg/L）、
耐碱（pH=10）、耐钙镁离子（总质量浓度 60 mg/L）、耐残余油（原油质量分数 15%）。实验表明，YUDP 在高

Abstract: Aiming at the characteristics of low permeability high temperature and high concentration of salt
in Jilin Oilfield, a temperature and salt resistant foaming agent YUDP suitable for this type of reservoir
containing hydroxyl and amide groups was developed. The effects of foaming agent concentration, solution
mineralization degree, temperature, pH, total content of calcium and magnesium ions, and residual oil
saturation on the foaming ability of foaming agent, foam stability and oil-water interfacial tension were
investigated. The results showed that YUDP had excellent temperature resistance (75 ℃), salt tolerance
(31037.9 mg/L), alkali resistance (pH=10), calcium and magnesium ion resistance (60 mg/L) and residual
oil (15% crude oil mass fraction). In addition, YUDP could maintain the oil-water interfacial tension at
–2
1×10 mN/m orders of magnitude in the high temperature and high concentration of salt environment,
which met the requirement of low interfacial tension flooding. When the mass fraction of YUDP was 0.4%,
the foaming volume was up to 250 mL, the half-life was 25.7 min, the foam strength reached 4187.75 mL·min,
–2
and the oil-water interfacial tension was 2.61×10 mN/m, all of them reached the requirements of low
interfacial tension foam flooding in Jilin Oilfield.
