摘　　要：番禺油田位于珠江口盆地珠I坳陷恩平凹陷西侧边缘,含油构造内发育多条断层,固井漏失风险大。固井通过单级双封、漂浮下套管、井眼清洁、断层防漏等一系列技术措施,有效降低了钻井和固井过程中的漏失,确保固井质量,满足后续生产要求。Panyu oilfield was located on the west margin of in Zhu I Depression of Enping Sag in Pearl River Mouth Basin.The redeveloped many faults in the oil-bearing structures,where the risk of ce-menting leakage was high.Cementing by single stage double seal,floating casing,hole cleaning,leakage prevention in faults and a series of technical measures are used for effectively reducing the leakage in the process of drilling and cementing,ensuring the cementing quality to meet the follow-up production requirements.
