Overview

      High temperature and high pressure shale dilatometer can simulate downhole formation temperature and pressure condition and detect the hydration expansion law of mud shale samples, evaluate the inhibiting ability of the related treating agent, select the suitable treated types or proportion of treating agent for drilling. It has important reference guide of studying of the stability of borehole wall, adopting scientific and economic treatment decisions, and the research and production about the inhibitory agents.
