摘　　要：在大位移井、大斜度井、水平井和深井钻井中 ,或者在狗腿严重度较大的井段 ,或者在技术套管下入后的长裸眼钻井过程中 ,常常出现套管磨损问题。由此而诱发的套管抗挤强度和抗内压强度降低问题制约了油井的后续完井测试作业的顺利进行 ,影响了油井寿命 ,严重时还会导致某段油井报废和整口油井报废。国内外学者研究了许多措施来减缓套管磨损问题。通过对这些措施的原理进行研究 ,为油田作业选用和科学研究提供借鉴。敷焊耐磨带的效果明显 ,操作方便 ,是深井钻井。For the extended well, high angle drilling, horizontal drilling and deep well drilling, or in the well section of large dogleg severity, or the long open hole, casing wear often happens. As a result, the collapse resistance and the bursting pressure of the worn casing will decrease, which will affect the well completion, well test, and oil well life, and sometimes gives rise to the abandonment of a well section or the whole well. Hence, the scholars at home and abroad have obtained some measures to abate the casing wear. In this paper, the principle of theses measures was studied, which will help the oil field to select or the researcher to study. Because of the good effect and convenience of the hardbanding, it is a good method to use in the oil field.
