Oil is vital to modern society, not only one of the most important energy sources, but also a variety of daily necessities, chemical raw material sources. “Black Gold” is enough to prove its importance, and CMC and PAC(Polyanionic Cellulose) does play an important role in oil exploitation.
In the drilling processing, oil company need to configure the good mud to ensure the normal operation of drilling rig, which requires a proper viscosity, specific gravity, water loss and some other indicators. At the same time, these indicators have their own requirements to meet different regions, different depths and different mud types. Adding CMC or PAC can help to adjust these indicators, reduce the water loss, and improve work efficiency.
CMC or PAC added to mud can help to reduce water loss by creating a thin but hard, low-permeability filter cake on the drill hole wall. It also allows the rig to get a low enough initial shear force to let trapped gas out of the mud and quickly throw away debris. Mud with CMC or PAC is stable and can effectively reduce water loss even at temperatures above 150℃. In addition to this, CMC and PAC as good stabilizers can help prolong the stable life of drilling mud, and also resist the damage of mud and bit which is caused by various soluble salts.
In oil drilling field, sodium CMC and PAC can be used in drilling fluid, fixing fluid and fracturing fluid. In drilling fluid, it works as viscosifier, filtration reducer and rheology controller; In fixing fluid, it is used to control fluid viscosity, suspend heavy objects and avoid fluid loss; In fracturing fluid, it is used to carry stuffing and avoid fluid loss.
SINOCMC can supply quality CMC and PAC for oil drilling and mining, welcome to inquire if any demand or interest.
