固井水泥环对套管承载能力的影响规律

INFLUENCING TENDENCIES OF CEMENT SHEATH ON CASING RETAINING CAPACITY

    摘要
  • 摘要: 固井质量的好坏直接影响油水井的使用寿命。通过采用计算机辅助工程(CAE)方法,研究了水泥环缺损、水泥环不居中以及水泥环的性质对套管承载能力的影响规律,提出了固井质量差导致套管损坏的基本机理。

     

    Abstract: Cementing quality influences the oil well life directly, and by applying CAE (computer-aided engineering) technology, the influencing tendencies of cement sheath quality (damages, un-centralizing and characteristics of it) on casing retaining capacity are studied. The basic mechanism of casing damage due to poor cementing quality is also presented.
