Plant-based gum for oilfield geological drilling fluids

Composition: Made from various wild plants through slicing, drying, crushing, and winnowing.

Characteristics: Appears as a light yellow free-flowing powder, forming a highly viscoelastic fluid upon contact with water.

Main Properties:

Water Solubility: Plant gum is insoluble in any organic solvents such as ethanol, glycerol, or formamide; water is the solvent for plant gum. Viscosity: Plant gum swells and hydrates upon contact with water to form a high-viscosity sol. Its viscosity increases significantly with higher powder concentration. Plant gum solution is a non-Newtonian fluid, with viscosity decreasing as shear rate increases. Salt Tolerance: Due to its non-ionic nature, plant gum solution is generally unaffected by anions or cations and does not undergo salting-out. Gel Formation: Hydrated plant gum can cross-link with various chemical reagents such as borax and dichromate to form a non-Newtonian water-based gel with certain viscoelasticity. The viscosity of this gel is tens to hundreds of times higher than that of the gum solution.

Quality Indicators:

Main Applications:

① Exhibits excellent rheological properties, contributing to wellbore stability and effective drill cuttings transport, significantly improving drilling speed and reducing drill tool wear.

② Provides effective plugging for fractured formations, sandstone layers, and other permeable strata.

③ Forms a protective film on rock samples during coring, resulting in higher core recovery rates.

④ This product is purely natural, biodegradable, and environmentally friendly.
