两种常用表面活性剂在砂岩表面吸附特性的分子模拟
Molecular simulation of absorption properties of two commonly used surfactants on sandstone
摘要
Abstract
Two surfactants widely used in oilfield-SDBS(sodium dcdecyl benzene sulfonate) and sodium stearate being taken as research objectives,and silica as rock,the multi-crystal cell models of two surfactants are established using Materials Studio( MS)soft-ware. The dynamic molecular simulation results show that,the molecules of SDBS more easily gather than those of sodium stearate, which makes its CMC (critical micelle concentration) lower; SDBS more quickly reaches to stable temperature,its final temperature is high-er ; SDBS more slowly reaches to stable energy, and its final energy is lower. The results can provide reference for the selection of oilfield surfactants and the development of new high-performance surfactants.关键词
