Product Overview

CAS 1318-93-0 Montmorillonite Nanoclay is natural layered silicate mineral with nanostructured lamellar texture.

Once hydrated in water-based drilling mud, the stacked silicate layers separate and build a stable colloidal network. It efficiently raises mud viscosity and yield point, strengthens cuttings suspension and transportation capability. Meanwhile, it forms compact filter cake on borehole wall to reduce filtration loss, stabilize wellbore formation and prevent collapse. This nanoclay maintains steady rheological properties under variable temperature and pressure downhole environment. It acts as a high-performance viscosifier and essential functional additive for oilfield water-based drilling fluid systems.

Product Properties

The product is light beige fine powder with complete layered crystal structure. It hydrates rapidly in aqueous medium to form uniform colloidal dispersion. Able to form thin, dense and low-permeability filter cake. Good compatibility with common drilling fluid additives such as fluid loss agents, inhibitors and weighting materials. It retains stable rheology within the operating temperature range of conventional water-based drilling mud. Low harmful soluble salt content minimizes adverse impacts on drilling fluid system.

Core Advantages

Fast hydration speed. Quickly build viscosity after mixing into water-based mud.

Excellent viscosifying & shear thinning performance. Improve cuttings transport while lowering circulation resistance.

Effective fluid loss control. Generate tight filter cake to reduce water invasion into formations.

Outstanding wellbore stabilizing capacity. Restrain shale hydration and borehole collapse.

Good compatibility. Can be compounded with various drilling fluid treatment agents.

Cost-efficient additive. Achieve desired mud rheology at moderate addition dosage.

Main Applications

Montmorillonite Nanoclay works as viscosifier for oilfield drilling mud. Typical application scenarios:

Onshore & offshore water-based drilling fluids, horizontal well drilling mud, shale formation drilling systems, workover & completion fluids, trenchless horizontal directional drilling slurry, geothermal well drilling mud.

Usage Guidance

Slowly add montmorillonite nanoclay into circulating water under continuous agitation to avoid agglomeration.

Fully stir for adequate hydration before introducing other drilling additives.

Adjust addition dosage according to target viscosity, generally 2%–6% of total mud weight.

Conduct laboratory rheology test to optimize formula before on-site deployment.

For high-temperature deep well operation, match with suitable high-temperature stabilizer as required.

Packing & Storage

Standard package: 25kg kraft paper bag with inner PE waterproof liner. Samples are available upon request.

Seal packages tightly to prevent moisture absorption. Store in cool, dry and ventilated warehouse. Avoid rain soaking and long-term sunlight exposure. Prevent severe extrusion during transportation to avoid powder caking.
