wholesale Polyanionic Cellulose

Suitable for freshwater, brine, saturated brine, and seawater drilling fluid systems. In drilling fluids, it acts as a viscosifier, flow controller, and filter reducer, exhibiting strong suspending ability. It stabilizes the wellbore and prevents mud outflow. In completion fluids, it controls fluid viscosity, suspends heavy objects, carries filler, and prevents fluid loss. It can also replace guar gum in fracturing fluids.
 

Product Characteristics and Applications of Polyanionic Cellulose Drilling Polymer

1. Applications in Oil Drilling Fluids

1.1 Non-dispersed Systems
Polyanionic cellulose powder has strong slag-carrying capacity, inhibiting clay dispersion, reducing clay discharge rate, stabilizing the wellbore, and effectively improving drilling speed.

1.2 Dispersed Systems
Good suspension ability significantly increases particle stability; ideal for preparing high-density drilling fluids and adjusting drilling fluid rheology; forms dense, high-quality mud cake in drilling fluids. PAC effectively reduces fluid loss and free water.

1.3 Calcium-Treated Drilling Fluids
Good anti-calcium ability prevents excessive flocculation of clay particles caused by calcium ions, keeping the drilling fluid in a flocculated state, maintaining stable solids content and rheological properties, thus giving the drilling fluid good and stable performance.

1.4 Brine Drilling Fluid, Seawater Drilling Fluid, Saturated Brine Drilling Fluid
Polyanionic cellulose exhibits low sensitivity to salts and strong resistance to salts, calcium, and magnesium, making it suitable as a rheology modifier. It rapidly adjusts drilling fluid rheology under low-dosage conditions. Simultaneously, it quickly removes drill cuttings, maintains a low solids content, and improves drilling speed. When used as a filter cake, it forms a dense mud cake; because the filtrate filtered from the cake is very similar to the original formation water, it causes less damage to oil and gas reservoirs.

1.5 Potassium-Based Drilling Fluid
Petroleum-grade PAC exhibits low sensitivity to potassium, calcium, and magnesium salts; it rapidly and efficiently adjusts drilling fluid rheology. Besides its excellent filtration loss reduction effect, it also has the ability to clean drill cuttings and drill bits, showing significant effectiveness against drill bits prone to formation clogging.

1.6 Polymer Drilling Fluid
Petroleum drilling grade polyanionic cellulose (PAC) has good compatibility with other polymers, strong suspending power, and can quickly and efficiently remove drill cuttings, keeping the drilling fluid with low solids and low clay dispersion. It is also an excellent filtration reducer.

1.7 Low Solids Drilling Fluid
It quickly and efficiently adjusts the rheology of the drilling fluid, has excellent suspending power, removes drill cuttings promptly and effectively, maintains low solids content, improves drilling rate, stabilizes the wellbore, and has a good filtration reduction effect.

1.8 Environmentally Friendly Drilling Fluid
PAC powder is environmentally friendly, non-toxic, harmless, odorless, and biodegradable, and does not easily decompose during use. Due to its low maintenance cost, the health and safety of construction personnel are guaranteed. It meets the needs of various complex geological conditions and is harmless to agricultural production.
 

2. Applications in Completion Fluids

2.1 Improves the fluidity of cementing fluids, ensuring suitable initial adhesion, low filtration loss, and protecting the wellbore while preventing cementing fluid from flowing into pores and fractures.

2.2 Filler Fluids
Adjusts the fluid's fluidity, thixotropy, and suspended solids. Due to its excellent salt resistance (especially against monovalent metal ions), this product is particularly effective in filler fluids used in clean brine environments.

2.3 Fracturing Fluids
Rapidly increases the viscosity of fracturing fluids, carrying proppant into oil well fractures, creating permeability channels, rapidly reducing filtration loss, and quickly increasing formation pressure to achieve pressure transmission. Leaves no residue, is harmless to the base material, and can replace guar gum.
