PAC&CMC for Oil Drilling

PAC & CMC is used in oil drilling fluids, cementing fluids and fracturing fluids. It is mainly used as a tackifier, fluid loss reducer and rheology control agent in drilling fluids; it is used to control fluid viscosity, suspend heavy objects and prevent fluid loss in cementing fluid; it is mainly used to carry filling in fracturing fluid. Objects, prevent fluid loss.

1. Application of  CMC in fresh water, seawater and saturated brine:

* It has uniform substitution molecules, low dosage and high pulping rate.

* Good salt and alkali resistance, strong antibacterial performance and easy to use.

* The fluid loss and viscosity-increasing effect are obvious.

* Rheology control and suspension ability.

2. Application of  CMC in drilling fluid:

* Protect the drill bit and increase the drilling speed.

* In low-solids and solid-free drilling fluids, the fluid loss can be significantly reduced and the thickness of the cake can be reduced.

* It has a good inhibitory effect on shale hydration.

3. Application of  CMC in cementing fluid:

* It can better protect the well wall and prevent fluid from entering the pores and cracks.

* It can better control fluid viscosity, heavy material suspension and prevent fluid loss.

4. Application of CMC in fracturing fluid:

* CMC products are used in fracturing fluids to efficiently carry "fillers" into the fractures of oil wells and establish permeate channels for effective fluid control.

* Enter the oil well structure to reduce fluid loss and reduce pressure drop.

* Ultra-high viscosity products can also replace guar gum, reducing production costs.
