碱/表面活性剂/聚合物三元复合驱是既可以提高油层波及体积又能提高驱油效率的三次采油方法,表活剂的主要作用是降低待捕集的原油与驱油流体之间界面张力。而影响表活剂界面张力的因素很多,本文从测定方法及仪器的影响进行研究,通过一系列的室内实验,确定各项因素对界面张力测定的影响大小,并给出最佳参考的仪器参数及测定方法。
Alkaline / Surfactant / Polymer ASP flooding is a tertiary recovery method that can both increase reservoir volume and improve flooding efficiency. The primary role of surfactant is to reduce the interface between the crude oil to be trapped and the displacer fluid tension. However, there are many factors that affect the interfacial tension of surfactant. In this paper, the influence of measuring methods and instruments is studied. Through a series of laboratory experiments, the influences of various factors on interfacial tension determination are determined, and the best reference instrument parameters And determination method.
