Bentonite for mud
Category
- Product Description
-
RD mud bentonite is a functional mineral material made from natural bentonite as raw material, after selection, purification, and special process modification. Its core mineral component is montmorillonite (content ≥85%). The unique layered crystal structure of montmorillonite gives the product excellent water absorption and expansion, colloidal suspension, and thixotropy, making it an indispensable mud treatment agent in drilling, geological exploration, and pile foundation construction.
Performance Advantages
● High Slurry Rate
After absorbing water, this product can quickly disperse to form a uniform and stable colloidal slurry. 1 ton of product can prepare 8-12 cubic meters of qualified drilling fluid, which is much higher than ordinary bentonite, greatly reducing the unit cost.
● Low Filtrate Loss
The montmorillonite molecular layer can form a dense mud cake on the well wall, significantly reducing the filtrate loss of the drilling fluid to the formation, protecting the well wall stability, and preventing well collapse and leakage accidents.
● Excellent Salt and Pollution Resistance
After special salt-resistant modification treatment, it can maintain the stability of the mud even in saline aquifers or complex geological conditions, suitable for various drilling environments such as freshwater, saltwater, and gypsum salt layers.
● Controllable Thixotropy
When stationary, the mud viscosity increases to form a gel, preventing solid phase sedimentation; when stirred, the viscosity decreases rapidly, facilitating pumping, balancing the contradiction between "suspension" and "flow".
Application Areas
● Oil and Gas Drilling: Used in the preparation of drilling fluids for oil and gas wells, protecting oil and gas layers, and improving drilling efficiency.
● Geological Exploration: In hydrogeological and engineering geological drilling, stabilizing the borehole wall and carrying core samples.
● Pile Foundation Construction: In bored pile and diaphragm wall construction, preventing borehole collapse and improving concrete pouring conditions.
● Trenchless Engineering: In horizontal directional drilling and pipe jacking, lubricating drilling tools and stabilizing boreholes.Product Index
