Abstract

Borehole instability is one of the most complex downhole problems in the drilling process. In order to study the micro-mechanism of inorganic salts on shale hydration, a micro-crystal structure model of Na-montmorillonite was established using the MS software. The shale hydration mechanism, mechanical strength change due to hydration and the inhibition mechanism of inorganic salts were studied by molecule dynamic simulation. The simulation results showed some basic microscopic property, and agreed with the experiment.
