由于高矿化度水含盐量大、表面张力高、腐蚀性强,一般表面活性剂在高矿化度的水中的活性极大降低,所以在海水中不能用一般表面活性剂作为洗涤剂使用.文献报道某些特殊功能的表面活性剂耐受矿化度范围是110000 mg·L~(-1)以下(碱土金属只能在2500 mg·L~(-1)以内).复合α-烯基高分子聚醚羧酸盐耐受碱金属盐高达150000 mg·L~(-1),其中,耐受碱土金属高达20000 mg·L~(-1)左右.用于海水洗涤具有优异的洗涤效果和防锈、防腐蚀效果;用在高矿化度稠油开采中,能把储层矿化度高达150000 mg·L~(-1)左右、碱土金属高达20000 mg·L~(-1)左右的黏度高达100000 mPa·s (50℃)以上的特稠油乳化降黏至50 mPa·s (50℃)以下.

As its activity falls in high salinity water, the usual surfactant cannot be used for washing because of much salt, and increased surface tension and corrosion.It was reported in literature that some special surfactant can resist salinity up to 110000 mg·L~(-1) (alkaline earth metals up to 2500 mg·L~(-1)).A compound α-olefine polyether carboxylate whose range of resisting salinity up to 150000 mg·L~(-1) (alkaline earth metals up to 20000 mg·L~(-1))was introduced.Its washing and anti-corrosion effect in sea water was excellent.In the production of high-salinity heavy oil, it can reduce the viscosity of oil with formation water salinity as high as 150000 mg·L~(-1) (alkaline earth metals up to 20000 mg·L~(-1))from 100000 mPa·s (50℃) to 50 mPa·s (50℃).
