| 摘 要： | 利用LUMisizer LS610稳定性分析仪研究了胜利油田纯梁原油乳状液的稳定性和液滴直径的变化规律，考察了不同结构破乳剂对乳状液稳定性的影响。结果表明，在离心力的作用下，大液滴沉降得更快，导致靠近样品池底部位置的透光率偏高，大液滴较多。直链的非离子破乳剂BP01吸附能力较强，在低质量分数时即表现出高效的破乳能力；支链非离子破乳剂PA05由于其特殊的支链结构，吸附能力较弱，对乳状液的破坏能力略弱于BP01；阳离子破乳剂HY01在离心力场中对乳状液稳定性的影响不明显。

| Abstract: | The emulsion stability of Shengli oilfield Chunliang crude oil and variation of droplet diameter were investigated by using LUMisizer in different conditions. At the same time, the influence of demulsifiers with different structures on the stability of emulsion was also explored. The results showed that the droplets with large diameter settled faster, which resulted in the higher transmission and larger droplet at the bottom of sample cell. The linear demulsifier BP01 had effective ability to destroy the crude emulsion at low mass fractions because of its strong adsorption at oil water interface. On the stability of crude emulsion the demulsifiers PA05 with branched structure had weaker effect than BP01, while cationic reversed phase demulsifiers HY01 had little effect in centrifugal force field. |
