钻井废水和酸化压裂作业废水处理技术研究进展

Progress in Treatments of Drilling, Acidizing and Hydrofracturing Wastewaters in China

对近 15年来国内石油天然气工业应用和 (或 )研究钻井废水、酸化、压裂废水处理技术的情况作了综述。对钻井废水处理的讨论较多 ,包括废水组成和特点 ,处理工艺技术 ,处理药剂 ,处理工艺装置 ,现有处理技术的不足及发展建议。有关酸化 (盐酸酸化 )废水和压裂 (水基聚合物冻胶压裂 )废水处理的论述较少 ,分别包括废水组成和特点 ,处理技术研究现状及发展建议。表 4参 36。

The progress in treatments of driling, acidizing and hydrofracturing wastewaters in domestic oil and gas industry in recent 15 years is reviewed. To drilling wastewater treatments relatively more informations and discussions are given and cover wastewater composition and characteristics, treating technologies and chemical and other agents, technologic apparatus, disadvantages of present technologies, and comments for further development. As to acidizing (with HCl acid) and hydrofraturing (with aqueous polymer gel) wastewaters, limited informations and discussions cover wastewater composition and characteristics, present status of researches on treating technologies and comments on their further development.
