Oil Drilling Mud Primary Emulsifying Agent With Resistance To High Temperature

Primary Emulsifier | Secondary Emulsifier For Oil Drilling With Resistance To High Temperature

Primary Emulsifier | Secondary Emulsifier , Oil-based drilling fluid is the drilling fluid with oil as the continuous phase. Compared with oil-based drilling fluid and water-based drilling fluid, the oil-based drilling fluid has many advantages, such as resistance to high temperature, resistance to salt and calcium invasion, good for borehole wall stability, good lubricity and less damage to oil and gas layers.Oil-based drilling fluid is the drilling fluid with oil as the continuous phase.

CPMUL-P and CPMUL-S serves as a primary emulsifier in oil-base mud systems. It is formulated to give good emulsification, improved thermal stability of the invert emulsion, and enhanced high-temperature, high-pressure (HTHP) filtration control. Through comprehensive tests in a number of oil-base mud formulations with various base oils, mud densities, oil/water ratios and hot-rolling temperatures, it proves that at working temperature up to 149oC (300oF), CPMUL-P can maintain high ES (electrical stability), low HTHP filtrate and desired rheological property

CPMUL-P comprises of modified amidoamine, oxidized fatty acids and low-toxic organic solvent.
