摘要

以不饱和醇作引发剂利用双金属氰化物(DMC)催化加成共聚环氧丙烷、环氧乙烷，然后磺化中和成盐，研制出一种耐盐活性剂。该活性剂的耐受矿化度范围为2000～150000 mg8226;L-1。该活性剂不仅能把高矿化度水的表面张力从80.5 mN8226;m-1(30℃)降到37.1 mN8226;m-1(30℃)，而且即使水中的Ca2+、Mg2+浓度高达10000 mg8226;L-1时，其表面活性剂水溶液也是无色透明的，没有任何沉淀和絮状物。在某油田稠油水中矿化度高达150000 mg8226;L-1的稠油降黏实验中发现，该活性剂能使含水稠油黏度从85000 mPa8226;s(30℃)降到14 mPa8226;s(30℃)，并且还能使脱水后的原油本体黏度降低一半以上。

Abstract

Epoxyethylene and epoxypropylene were polymerized by double metal cyanide (DMC) with unsaturated alcohol as initiator.The obtained polyether was sulfonated

and neutralized to prepare a salt-resisting surfactant.The surfactant resisted water salinity in a range of 2000 mg8226;L-1 to 150000 mg8226;L-1.In addition

the surfactant exhibited significant effect on reducing the surface tension of high salinity water from 80.5 mN8226;m-1 to 37.1 mN8226;m-1 at 30℃.Moreover

even when the concentration of calcium or magnesium cations in the water reached 10000 mg8226;L-1

the surfactant solution remained colorless and transparent without deposition and flocculation.The experiment in oil field indicated that the salt-resisting surfactant reduced the viscosity of water-containing heavy oil from 85000 mPa8226;s to 14 mPa8226;s.After demulsification

the intrinsic viscosity of the dewatered crude oil decreased by half.
