Polyanionic cellulose commercial uses

Usage: Drilling fluid

Features: The mud fluid formulated with petroleum drilling grade polyanionic cellulose (PAC-HV, PAC-LV) has good water loss reduction, inhibition, high temperature resistance and salt resistance.

Slurry making in fresh water, 4% salt water and saturated salt water; when the dosage is 35-40% of traditional CMC, its viscosity improvement and fluid loss reduction capabilities are similar in fresh water drilling fluids, and in 4% salt water and saturated salt water drilling fluids The medium is the best, that is, it has stronger resistance to salt gypsum and is used in oil drilling, especially suitable for deep wells, high temperature wells, salt water wells and offshore oil drilling.

■Suitable for any mud from fresh water to saturated salt water;

■Pulping, the pulping volume of PAC can reach 2-3 times that of ordinary CMC;

■Low-viscosity PAC can effectively reduce filtration loss, while high-viscosity PAC has a high pulping capacity and has an obvious effect on reducing filtration and water loss;

■Mud fluid can inhibit the dispersion and expansion of clay and shale in high-salt media, thereby controlling wellbore pollution and delaying the hydration, expansion and dispersion time of clay;

■Has good protective colloid ability;

■PAC can be used in many complex formations such as salt, paste layer, high temperature, etc., as well as in difficult drilling conditions such as oceans and deserts. It is ideal for PAC to be used as inhibitors and water loss reducing agents in drilling fluids. The mud fluid prepared by PAC can Suppresses the dispersion and expansion of clay and shale in high-salt media, thereby controlling wellbore pollution. Among the workover fluids, the workover fluid prepared by PAC has a low solid phase, which will not block the permeability of the production layer due to solids and will not damage the production layer; it also has low water loss, which reduces the amount of water entering the production layer. The incoming water will form a water ballast phenomenon due to emulsion blockage. Workover fluid formulated with PAC provides advantages that other workover fluids do not have:

■Protect production floors from destructive damage;

■It has the portability to clean the wellbore, and the workload of maintaining the wellbore is reduced;

■It has the ability to resist the penetration of water and sediment, and rarely foams;

■It can be stored or transferred from well to well, which is better than ordinary mud workover fluid. The fracturing fluid prepared with PAC can withstand 2% KCI solution (must be added when preparing the fracturing fluid) and has good solubility. It is easy to use and can be prepared on site. It has a fast gel-forming speed and strong sand-carrying ability. When used in formations with low permeability pressure, the fracturing effect is more effective.
