摘要
从力学分析入手，建立了井壁稳定问题的力学模型。针对川东地区高陡构造地层的特点，应用钻井资料，测井资料以及岩心试验结果，分析了高陡构造地层倾角对井壁稳定的影响，并提出了该地区钻井液密度的设计方法。
A mechanical model for well bore stability is established based upon mechanical analysis. The effects of dipangle of high inclined formation on well bore stability are analyzed byusing drilling, logging data and laboratory test of core for high inclined formation of Eastern Sichuan Area. Drilling fluid density design method for the area is established.
