摘　　要：渤海湾BZ19-6油田井深通常为4000多米,井底温度高、气层发育、地层压力体系多、且窗口密度窄,给固井作业提出了较大挑战。通过优化水泥浆性能和固井工艺,已钻井的固井质量优良率较高。本文中所采用的技术措施,可为同类井的固井作业提供借鉴。The well depth of BZ19-6 oilfield in Bohai Bay is usually more than 4000 meters,with high bottom hole temperature,developed gas reservoir,many formation pressure systems and narrow window density,which poses great challenges to cementing operation.By optimizing the performance of cement slurry and cementing technology,the excellent rate of cementing quality of drilled wells is very high.The technical measures adopted in this paper can provide reference for cementing operation of similar wells.
