油水井套管变形损坏的模糊评判

FUZZY DIAGNOSIS ABOUT CASING DEFORMATION IN OIL AND WATER WELL

    摘要
  • 摘要: 造成油水井套管损坏的原因很多,机理复杂,很难通过已知条件来判断井下套管的损坏情况,更无法对其进行预测。用模糊综合评判方法,在大量现场数据分析的基础上,应用模糊数学理论建立起套管变形损坏原因与结果之间的新型关系,可以利用生产现场的已知条件对套管变形损坏情况进行判断,也为预测套管寿命提供了一条新的途径。

     

    Abstract: There are a lot of causes of casing failure.It is difficult to diagnosis downhole damaged casing,neither to predict casing condition.This paper presented a fuzzy evaluating method to analyze casing condition.On the basis of large number of field data,the relation between causes of damage and casing failure was established which can predict casing condition using field condition and founding anew path to predict casing life.
