百口泉采油厂压裂返排液处理剂的室内筛选及效果评价

Laboratory Screening and Effect Evaluation of Fracturing Flowback Fluid Treatment Agent in Baikouquan Oil Production Plant

通过对百口泉采油厂压裂返排液进行水质化验分析,得出压裂返排液原样离子含量、水型。结合返排液的特性,通过室内实验进行室内药剂的筛选,主要实现破胶剂、复合混凝剂、加载絮凝载体、复合絮凝剂、缓释剂的筛选,总结出各药剂理想选型和最佳投加量,为百口泉采油厂周边地区或相似类型压裂返排液的处理提供试验依据。

Based on water quality analysis of fracturing flowback fluid in Baikouquan Oil Production Plant,the original ion content and water type of fracturing flowback fluid are obtained.Combined with the characteristics of backflow fluid,the laboratory tests are carried out to screen the agents,mainly including breaker,composite coagulant,loaded flocculant carrier,composite flocculant and slow-release agent.The ideal selection and optimal dosage of each agent are summarized,which provide the experimental basis for the treatment of fracturing backflow fluid around Baikouquan Oil Production Plant or similar types.
