表面活性剂在油田中的应用

Applications of Surfactant in Oil Field

综述了表面活性剂在油田中的应用。在钻井中 ,表面活性剂用作起泡剂、乳化剂、页岩抑制剂、润滑剂等 ;在采油中 ,表面活性剂用作驱油剂、培水剂、酸化添加剂、压裂添加剂、防蜡剂、乳化降粘剂、解堵剂等 ;在原油集输中 ,表面活性剂用作破乳剂、消泡剂、除油剂、防垢剂、缓蚀剂、杀菌剂等。同时介绍了油田用表面活性剂的发展趋势。

Applications of surfactant in oil field have been reviewed.Surfactants used in drilling include foamer,emulsitter,shale inhibitor,lubricant etc.Surfactants used in oil production include oil displacement agent,water shutoff agent,additives used in acidizing and fracturing,viscosity reducer by emulsification deplugging agent etc.Surfactants used in gathering transportation,include demulsifier,defoamer,deoiler,scale inhibitor,corrosion inhibitor,bactericide etc.The developing tendencies of surfactants used in oil field have been also introduced in this paper.
