摘要:

黏弹性表面活性剂(VES)凭借蠕虫状胶束的可逆组装,兼具增黏、黏弹性、可逆剪切、遇烃自破胶等特性,已成为油气开采工作液的重要组分。本文系统梳理了VES在油气开采主要作业环节的应用现状。清洁压裂液依靠胶束缠结网络悬浮支撑剂,破胶彻底、残渣极少,纳米粒子改性可进一步提升其耐温耐盐与滤失控制能力;自转向酸利用酸-岩反应就地增黏,实现高渗层暂堵与低渗层改造;砾石充填与连续油管作业则受益于其低摩阻、层流携砂和剪切可逆恢复特性。在化学驱与CO2驱油领域,VES兼具流度控制与界面活性,CO2响应型体系还可原位胶凝以抑制气窜、增强咸水层封存。总体而言,VES在低压低渗、煤层气等残渣敏感储层中优势突出,但耐温抗盐上限、阳离子体系乳化倾向及药剂成本仍制约其规模化替代。未来应通过纳米复合、多重非共价作用与无机盐诱导组装等途径提升综合性能,并推进绿色化与低成本制备。

Abstract:

Viscoelastic surfactants (VES) combine viscosity enhancement, unique viscoelasticity, reversible shearing and hydrocarbon-sensitivity, and have thus become key components of oil and gas working fluids. This review summarizes the mechanism, formulation and practical applications or potentials of VES in upstream oil industry. In clean fracturing fluids, entangled micellar networks suspend proppants while leaving minimal residue; nanoparticle modification further improves thermal and salt tolerance and fluid-loss control. Self-diverting acids exploit acid-rock reaction to thicken in situ, temporarily plugging high-permeability zones and diverting subsequent acid to low-permeability layers. Gravel packing and coiled-tubing operations benefit from low friction, laminar-flow sand transport and reversible shear recovery. In chemical flooding and CO2 flooding, VES provides both mobility control and interfacial activity, and CO2-responsive systems can gel in situ to mitigate gas channeling and enhance saline-aquifer sequestration. VES shows clear advantages in residue-sensitive reservoirs such as low-pressure low-permeability and coalbed methane formations, yet temperature and salinity limits, the emulsification tendency of cationic species and reagent cost still constrain large-scale substitution of polymers. Future work should enhance performance through nanocomposites, multiple non-covalent interactions and salt-induced assembly, while advancing green and low-cost preparation.

Key words: viscoelastic surfactant, wormlike micelles, oil and gas production, clean fracturing fluids, self-diverting acid
