CAS NO:471-34 Calcium Carbonate Superfine Powder Calcium Carbonate

Ultrapure calcium carbonate is produced via physical crushing or chemical synthesis using calcium carbonate as the raw material. It appears as a white powder, featuring non-toxic, odorless, and water-insoluble properties, with strong chemical stability. The particles can penetrate into fractures of various sizes, forming a barrier structure through filling to effectively prevent drilling fluid loss.

Targeted Treatment for Fluid Loss Issues

Micro-fracture and High-Permeability Formation Loss：Leveraging the strong dispersibility of ultra-fine particles to fill formation pores and reduce permeability. For example, in sandstone formations, 1-5μm calcium carbonate particles can quickly plug 0.5-20μm pore channels.

Macro-fracture and Karst Cavity Loss：Compound with coarse-grained materials (such as walnut shells, mica flakes) to form a multi-layer plugging structure of "coarse-grain bridging + fine-particle filling", suitable for severe fluid loss scenarios with a loss rate exceeding 10m³/h.

Drilling Fluid Performance Adjustment

As an inert solid additive, ultra-fine calcium carbonate can moderately increase the viscosity and yield point of drilling fluids to assist in maintaining wellbore stability, while exerting no significant impact on fluid rheology. It is highly suitable for complex well types like directional wells and horizontal wells.
