n: A kind of invert emulsion mud that the chemical potential of drilling fluid is equal to the chemical potential of water in the drilled formation. The salinit in the water phase is usually equal to salinit in the shale water. It can prevent shale permeatin

n: A kind of anionic surface active agent. Used for the component part of emulsifier of invert emulsion mud and pipe lax.

n: see oil-in-water emulsion mud.

n: a kind of negative ion surfactant ,mainly used as emulsifier of invert emulsion mud

n: refer tohigh-filter-loss inverted emulsion mud

n: a kind of invert oil mud whose filter loss is 8-12ml under high temperature and pressure and whose content of liquid phase and colloid is low

invert emulsion mud.

n: also called water-in-oil emulsion mud,oil is continual external phase and water is dispersed phase.

water-in-oil emulsion muds. There may be as much as 50% brine in the liquid.

n: an invert emulsion is a water-in-oil emulsion where fresh or salt water is the dispersed phase and diesel, crude or some other oil is the continuous phase and increase the viscosity and oil reduces the viscosity.
