随江汉油田采出液含水量不断升高,现场破乳剂FT1023已不能满足采油需求。将亲水性多羟基聚缩水甘油醚(HPG)或其酸酐改性产物与疏水性低聚六氟环氧丙烷聚合物(HFPO)氟化,制得两性型树枝状大分子破乳剂(HPRf系列:HPRf1、HPRf2、HPRf3、HPR... 随江汉油田采出液含水量不断升高,现场破乳剂FT1023已不能满足采油需求。将亲水性多羟基聚缩水甘油醚(HPG)或其酸酐改性产物与疏水性低聚六氟环氧丙烷聚合物(HFPO)氟化,制得两性型树枝状大分子破乳剂(HPRf系列:HPRf1、HPRf2、HPRf3、HPRf4)。表征测试结果表明,将疏水性HFPO引入HP系列末端可有效提升大分子的破乳效果,其中HPRf2对江汉油田采出液破乳效果最好,破乳性能优于FT1023,最宜使用条件为:使用温度65℃,用量75 mg/L,破乳150 min基本脱水完全,脱出水含油量低于20 mg/L,可直接用作三次采油回注水。研究表明破乳剂HPRf2能满足江汉油田采油需求。 展开更多

Alzheimer's disease(AD)is a clinically common degenerative disease of the central nervous system with a complex pathogenesis,which seriously endangers the physical and mental health of the elderly.In recent years,a large number of studies have shown that the intestinal flora can regulate the central nervous system through the brain-gut axis,thereby participating in the occurrence and development of AD.AD belongs to the category of"dementia"and"forgetfulness"in traditional Chinese medicine.It is caused by internal injury of seven emotions,old age and chronic illness,which can cause insufficient blood,deficiency of kidney essence,and blockage of phlegm and blood.To use,treat more from the heart,liver and kidney.We believe that phlegm turbidity blocking the orifice is the key to the pathogenesis of AD.It should be treated from the spleen,and according to the characteristics of the pathogenesis,the method of warming the spleen and dredging the collaterals and resuscitation is proposed to prevent AD.This article takes the intestinal flora as the starting point to discuss the research progress of treating AD from the spleen. 展开更多
