CMC & PAC can be used as fluid loss reducer or viscosifier in
drilling fluids. The function of CMC is to reduce the fluid loss as much
as possible through forming low permeability, flexible, thin and
compact filtration cake on borehole wall. Used as thickening agent,
suspension agent and plugging agent.
Our PAC-HV/LV (oil
drilling grade) and CMC-HV/LV are advantageous because of their small
dosage, high yield, anti-bacterial, good salt tolerance properties and
convenient to use, reduction of fluid loss, and improvement of
viscosity, flowing control and strong suspending
capability, environmental friendly, non-toxic, harmless and
odorless, and good liquidity, convenient to construction.
1. Excellent temperature resistant and salt resistant properties.
capability of carrying crumbs, restraining the dispersion of the clay,
reducing the speed of pulp yield by clay, stabilizing the well wall and
effectively increasing the drilling rate.
3. Easily disperse in water based drilling fluid. CMC & PAC can be used in fresh water to saline water drilling fluids.
4. Less residue. Can prevent fluid flow into pores and cracks.
fracturing agent, CMC & PAC can provide good sand suspension
effect, apparently reduce fluid loss and thin filtration cake. Have
strong inhibition effect of shale water.
6. Good suspending
capability, containing more solid phases, greatly increasing the
stability of granule, best for configuring the high density drilling
fluids, and adjusting the rheology of drilling fluid, forming the
compact high quality mud cake in the drilling fluids. It has the good
function of reducing the fluids loss and free water.
compatibility with other polymer, strong suspending power, cleaning
drilling crumbs fast and efficiently, making the drilling fluids stay
into low solid phase and low dispersion of clay, and it is also the good
filtration reducer. Adjusting the rheology of drilling fluids fast and
efficiently, excellent suspending power, cleaning drilling crumbs
promptly and efficiently, maintaining the low solid content, enhancing
the speed of the drilling rate, stabilizing the well wall, and
possessing the good effect in filtration reducer.
