摘要：

以多孔介质弹性力学理论为基础,以渗流力学理论为纽带,建立泥页岩地层井壁稳定的力学与化学耦合分析模型. 利用该力化耦合模型,可以分析钻井液活度、膜效率等因素对坍塌压力的影响规律,因此可以优选钻井液体系. 为泥页岩井壁稳定研究提供一定的理论依据.

关键词: 膜效率;孔隙压力;力化耦合模型;泥页岩

Abstract:

Based on the poroelasticity theory and seepage mechanics, the wellbore stability model coupled mechanicschemical effect for shale formation was put forth. Rules about activity of drilling fluids and membrane efficiency affecting on wellbore collapse pressure were obtained by the model, which could offer the theoretical basis for research on wellbore stability.

Key words: membrane efficiency； pore pressure； model coupled mechanics and chemistry； shale formation
