Abstract

Abstract: The analysis of an actual field case study indi-cates that the improvement of cementing quality is a systematic engineering. Factors such as proper slurry
design, adjusting rheological parameters of mud and slurry, selecting flow regime of displacement mud,central casing, maintaining balance between forma-tion pressure and slurry column pressure, and regu-larity of hole shape are all needed to be carefully tak-en into consideration when planning a cementing job in order to enhance the displacement efficiency of mud by slurry, prevent channeling and obtain excel-lent zone sealing.

Key words: Cementing, Quality, Factor, Pressure bal-ance, Sealing, Case study
