摘要

井壁稳定性问题一直是困扰钻井过程的重要问题。目前钻井中井壁不稳定的现象频频发生,加大了了钻井作业的施工困难,也使固井的质量下降。本文分析井壁稳定性的目的和意义,井壁失稳的原因、机理,提出了目前在钻井方面采用的井壁稳定性预测的主要方法:基于地震属性的井壁稳定性预测方法和利用测井资料的井壁稳定性预测方法。
Wellbore stability problem is always an important problem plaguing the drilling process. At present, the wellbore instability phenomenon in drilling occursfrequentlywhich increases the difficulties in construction of drilling operation, also makes the cementing quality decline. This paper analyzes the purpose and significance of wellbore stability, stability reasons,wellbore mechanism, then puts forward the main methods currently used in predicting wellbore stability during drilling:Prediction method of wellbore stability of seismic attributes based on and Prediction method of wellbore stability by using logging data.
