Description

Product Description:
In the process of drilling production and production oil, gas and water wells, polyanionic cellulose (PAC) used as additives for drilling fluids performs two functions - creates a filter layer at the walls of the well to minimize water loss and controls the rheology of liquid systems.
Both water and organic solvents can serve as the basis for drilling fluids, but today's environmental protection requirements and technological features of well drilling processes determine the use of water-based drilling fluids in most cases. Since PAC is a water-soluble polymer, it is used in drilling fluids as an additive that improves the performance of pulps. In contrast to CMC, PAC is more effective in unsaturated solutions.

In addition to the two main functions mentioned, the PAC performs the following functions:
● due to its film-forming properties, it slows down the erosion of the well walls, preventing it from falling asleep
● Improves the cooling and lubricating properties of drilling fluids
● Helps maintain the thermal and biological stability of drilling fluids
● PAC is a biodegradable, environmentally friendly, non-toxic additive to drilling fluids that controls the rheological properties and improves their performance characteristics for more successful performance of their functions.
Modern drilling fluids are increasingly facing more stringent environmental controls. CMC and PAC are water-soluble polymers derived from cellulose. They are eco-friendly, fully biodegradable and non-toxic. Therefore, they can be used all over the world without restrictions.
