摘要
分析了D2-20大位移井固井中存在的技术难点,给出了所采取的工艺技术措施,包括套管摩阻计算分析、提高顶替效率和水泥浆体系的优选等,该井固井的成功(固井质量为优),为今后同类型井固井提供了借鉴。
This paper analyzes the key technical points lying in the D220 ERW cementing operation and gives the used technological measures, including calculation of casing friction, improvement of displacement efficiency and optimum selection of cementing slurries. The successful cementing job of this well gives the references for later cementing jobs.
