环境自适应油田化学材料

Environmentally Self-Adaptive Oilfield Chemicals:A Literature Review

历经半个多世纪的发展,油田化学剂已成为油气开采不可或缺的关键材料,但低渗、高温、高盐等苛刻油气环境也给聚合物、表面活性剂等有机类油田化学材料的研发提出了新的挑战,传统的"被动抵抗"研究思路已难以完全满足要求。本文提出了性能可随环境条件变化而自发调节的"环境自适应油田化学材料"的新思路,并立足作者自己的工作,介绍了渗透率自适应聚合物、温度自适应聚合物及表面活性剂、盐度自适应聚合物、CO_2自适应黏弹性表活剂、pH自适应黏弹性表活剂的原理、性能和潜在应用。最后,展望了环境自适应油田化学材料在油气开采中的发展方向。图16参82。

After more than half a century's development,the oilfield chemical chemicals have become an indispensable materials for oil and gas production.However,the harsh oil and gas environment such as low permeability,high temperature and high salinity also poses new challenges to the research and development of organic oilfield chemical materials such as polymers and surfactants.The traditional"passive resistance"strategy cannot fully meet the requirements.In this paper,a new idea of"environmentally self-adaptive oilfield chemical materials"was proposed.Based on the author's own work,the principle,performance and potential of permeability adaptive polymer,temperature-adaptive polymer and surfactant,salinity-adaptive polymer,CO2-adaptive viscoelastic surfactant and pH adaptive viscoelastic surfactant were introduced on principle,properties and potential applications.Finally,the future trend of environmentally adaptive materials used in oil and gas production was prospected.
