【摘要】 原油破乳剂是国内外油田矿场所必需的化学药剂,可在针对性的破乳剂性能选择上一直缺乏系统的理论支持。由于原油组成的复杂性,加上影响形成乳化原油的因素众多,给原油破乳剂的研究工作带来许多困难。本文从原油乳状液的形成机理入手,分析了乳状液的稳定性原因、破乳机理、破乳剂分子结构性能、物化性能与破乳效果,提出了优秀的原油破乳剂所应具备的性能。更多还原

【Abstract】 Demulsifying agent is a kind of necessaries on oil gathering fields.Since the chemical composition of crude oil is complicated and many other factors affect the emulsion process,it is difficult to choose exact demulsifying agent for exact oil.This article starts with mechanism of crude oil emulsion,analyzes stability reasons,break theory,molecular structure and emulsion breaking performance,finally summaries the potential characters of excellent demulsifying agents.更多还原
