摘　　要：用物理实验方法来确定井壁稳定性即井壁缩径可能性。在岩心加持器中装入经过实验室处理过的岩样,通过对其同时加围压和轴压,测量一段时间间隔不同压力下的岩样的内径的变化,来确定实际地层中水平井井壁的缩小程度。同时也为完井提供一定的参考。Horizontal well borehole stability is discussed by experiments in the paper. A rock sample is drilled and saturated with brine, then installed into a core holder. A confining pressure is exerted on the core holder,at the same time,the inner diameter of core sample is measured under different pressure condition so as to establish the shrink extent of horizontal well borehole in actual formation. this reaserch offers some reference of well completion.

关 键 词：力学稳定性 缩径 完井
