三次采油用表面活性剂原料的生产和技术进展

Manufacture and technical advances in surfactant raw material for EOR

现有的烷基苯生产中,符合生产三次采油用表面活性剂的烷基苯原料产量有限,难以满足三元复合驱大规模工业化推广的要求。综述了目前国内外烷基苯和高碳烯烃的生产和研究发展概况,介绍了国外工业上生产高碳烯烃所用的Gulf法、Ethyl法、SHOP法和Linde法等,指出这些工艺虽然比较成熟,可以用于生产符合三次采油用烷基苯的原料C14-18烯烃产品,但是生产的烯烃都存在一定的碳数分布规律,因此需要自主研发新型的生产方法或工艺。

The outputs of alkylbenzene for EOR material in the present production are too small to satisfy the requirement of large-scale ASP industrial application. The general situation of national and international manufacture and research progress in alkylbenzene and higher-carbon olefin are reviewed. The processes abroad for higher-carbon olefin include Gulf, Ethyl, SHOP, and Linde ones, which can produce C14- 18 olefin. However, these existent processes are more or less confined to the carbon number distribution principle. Thus, the R＆D of novel production method and process out of their own efforts is absolutely needed to prepare the C14- 18 olefin.
