Oil drilling Grade CMC

APPLICABLE TO FLUIDS(CMC)

CMC-Na PHYSICAL CHEMISTRY QUALITY INDEX

PERFORMANCE IN MUD

CMC can be used as water-soluble gel for frilling fluids, and can form aresian well liquor.

²     It has good water-loss controlling ability, especially PAC is highly effective drop filter-loss agent. Even added at low quantity, it can control water loss at very high level, but does not affect slurry`s other characteristics.

²     It can form high quality slurry cake which is strong and flexible.

²     It has good temperature resistance and superior anti-salt character. Under certain salt density, it can remain good water-loss capability and certain rheology,so the viscosity in salt solution is the same as in water, which is specially suitable for sea misering and deep well.

²     It effectively controls the rheology of slurry, with good non-Newtonian fluid performance.

Moreover, CMC can be used as well fixing liquor to prevent fluid entering terrane or crack, and also canbe used as pressing liquor to control the loss of fluid into oil well structure.
