Device and method for testing surface hydration inhibition of drilling fluid

Abstract

A device for testing surface hydration inhibition of drilling fluid includes a reaction vessel, which is provided with a nylon filter cloth, a first fixing frame, and a second fixing frame inside. An end of the nylon filter cloth is detachably connected to the first fixing frame, and the other end of the nylon filter cloth is detachably connected to the second fixing frame. The first fixing frame is detachably connected to an inner wall of a top portion of the reaction vessel, and the second fixing frame is detachably connected to an inner wall of a bottom portion of the reaction vessel. After testing, the basal spacing of the sodium montmorillonite determined by XRD reflects the surface hydration inhibition performance of the drilling fluid. The device is suitable for testing the surface hydration inhibition of various water-based drilling fluids, providing substantial support for the development of drilling fluid technology.
