Bentonite for HDD Drilling

Thixotropy is a major advantage of organic clay bentonite. It means that the colloidal solution will become thin when stirred, that is, it will become thickening and the shear rate will increase when it is still when the shear force is reduced. For example, good thixotropy in drilling mud is a manifestation of the performance of organic bentonite.

When at rest, the hydroxyl groups in the bentonite structure produce hydrogen bonds, resulting in a homogeneous colloid with a certain viscosity.

When stirring in the presence of external shear force, the hydrogen bond is broken, the viscosity is reduced, so the bentonite solution in suspension when stirring as a very fluid solution; stop applying stirring will arrange itself into a three-dimensional mesh structure of the gel, and does not occur in the settlement of stratification and water separation.

when stirring again with external force, the gel can be broken quickly, and restore fluidity. For a large concentration of montmorillonite aqueous dispersion, as long as there is flocculation, there is thixotropy.

Adhesive properties,

It refers to the high viscosity in the colloidal suspension of bentonite, which is the frictional force between colloidal flowing solid particles and between solid particles and liquid.
Bentonite is mixed with water to form a substance with good adhesion, mainly because it is multifaceted. Bentonite has clear water, small particles, and its surface charge is relatively diverse, and the particles are also relatively irregular. Hydroxyl groups form hydrogen bonds with water .

Good Dispersity is also a feature of high expansive bentonite. At the same time, clay particles are relatively stable when gathered together under general conditions, and they have relatively good strength, gel strength. These characteristics are all organic bentonite, which can be used for drilling in oil fields.

At the same time, this kind of commission expands in water and requires sufficient time. Only with sufficient time can it stabilize. So its viscosity also increases for longer periods of time.

Plasticity.
Regarding the good plasticity of bentonite, we have rarely mentioned it. Its plasticity water content is much higher than that of kaolin and general minerals, and the required force for its formation is smaller than that of other clays.

The stress-strain values in bentonite vary with the type of montmorillonite exchange cation .The plasticity of sodium based bentonite is relatively high, and its adhesion is also strong.

The above excellent characteristics of bentonite encourage us to choose it. From them, we choose high-quality high-end bentonite to produce organic bentonite, so that all aspects of its performance can be fully reflected.
