APPLICATION OF SURFACTANT COMPOSITIONS AND ALKALINE BUFFER SYSTEMS

In the development of physicochemical technologies, a clear trend has emerged toward endowing oil-displacing fluids with self-regulating properties, allowing them to maintain their functions in the reservoir for extended periods. One version of this trend has been realized, based on the concept of an oil-displacing fluid as a physicochemical system with negative feedback. These concepts formed the basis for the development of physicochemical principles for selecting surfactant compositions, taking into account the thermodynamic and kinetic parameters of the oil-rock-aqueous phase system, which influence oil displacement from a porous medium.在油气开发理化技术的发展进程中，一条清晰的趋势已然显现：为驱油流体赋予自调控性能，使其可在油藏中长期维持其作用效能。该趋势的一个分支已得以实现，其核心是将驱油流体视为具备负反馈特性的理化系统。上述概念为筛选表面活性剂配方的理化原则开发奠定了基础，该原则需综合考量油-岩-水相系统的热力学与动力学参数——此类参数会直接影响多孔介质内的驱油过程。
