For characterizing the alkaline dissolution of montmorillonite, this paper applies Nitrogen Adsorption-Based large specific surface area (SSA) Measurement to measure the changing SSA, pore volume, and pore size, and to draw the adsorption/desorption curve of montmorillonite at different sodium hydroxide concentrations. It also determines the optimal experiment conditions like concentration (0.05mol/L) and charging/reaction time (3h) of sodium hydroxide solution which are suitable for oilfield development. According to the experiment, the dissolution characteristics of montmorillonite reflected by parameters acquired through Nitrogen Adsorption-Based SSA Measurement are consistent with the conclusion drawn from the changing pH value and ion (e.g. Si<sup>4+</sup>) concentration of the solution before and after the reaction. |
