摘　　要：从地质和工程方面分析了塔河油田S100井三叠系、石炭系地层钻井过程中井眼易失稳的原因,给出了其钻井液及工程技术措施。现场应用结果表明,该井井眼稳定,井径扩大率很小,有效地解决了井眼失稳问题。This paper analyzes causes of sloughing during drilling through Triassic and Carboniferous systems of well S100 in Tahe Oilfield proceed from geology and engineering aspects and presents the corresponding muds and engineering measures. The wellbore is effectively protected from sloughing with small enlargement rate because of applying these techniques.
