三元复合驱化学剂泄漏特征污染物的分析

Characteristic pollutants for chemicals leak of Alkali-Surfactant-Polymer compound flooding

随着三元复合驱(ASP)采油技术的推广应用,三元注入介质在运输、配制、存储、注入过程中发生泄漏的事故增多,对环境造成污染。文中通过检测大庆油田ASP中化学剂组成、含量以及ASP注入液和采出液的化学成分,根据国内外现有的标准和环境评价方法,确定出ASP对环境影响的主要特征污染物,为制定ASP发生意外泄漏后的治理预案打下基础。

With the extended application of Alkali-surfactant-polymer(ASP) compound flooding technology in oil production,leak accidents of ASP injection medium increased during transportation,preparation,storage and injection which caused pollution to environment.In this paper,according to the existing domestic and overseas environmental standards and evaluation methods,the main environment-influencing characteristic pollutants in ASP are identified by detecting the chemical compositions and contents of ASP chemicals as well as the chemical constituents of the injection liquid and flooding-produced liquid in Daqing Oilfield,and paved a foundation for making treatment plans for accidental leak of ASP.
