摘要
在我国石油工业,一次、二次采油对原油的采取率仅约40%。由于石油是不可再生资源,所以为了不造成浪费就不得不进行三次采油,而石油磺酸盐则是三次采油过程中常用的驱油剂,其制备工艺因选择的磺化剂不同而不同,作者则主要对以三氧化硫磺化制备石油磺酸盐的工艺和现在常用石油磺酸盐组成分析方法进行了综述与简要分析。
The utilization rate of the crude oil is only about 40 percent after the first and second exploi- tation for the oil industry in China. Owing to petroleum is a non-renewable resource,the crude oil has to be exploited again. Petroleum sulfonate is generally used in the third exploitation process as an oil displacement agent. The production ways of petroleum sulfonate vary from the different sulfonating a- gents. The paper reviewed those preparations of petroleum sulfonate by using sulfur trioxide and those analytical methods for its composition,and analyzed briefly their advantages and disadvantages.
