1. Product Overview
HTFT is an anti-collapse and plugging material specifically engineered for high-temperature water-based drilling fluid systems. Composed of fibrous materials, rigid ions, and deformable cementing materials, it is available in a series of products tailored to meet various temperature resistance requirements. HTFT appears as a black, free-flowing powder.
2.Functions and Characteristics
Cold Water Dispersibility: Effectively inhibits shale hydration expansion.
Cementation & Plugging: Contributes to wellbore stability with excellent cementation and plugging properties.
Lubrication: Prevents sticking and bit locking due to its good lubrication performance.
Rheological Properties: Maintains good mud rheological properties without increasing viscosity.
Temperature Customization: Offers customizable products based on specific temperature resistance needs.
Primary Functions
High-Temperature Stabilization
Prevents wellbore instability caused by high temperatures.
Fracture Sealing
- Seals fractures and micro-fractures within the wellbore.
Clay Hydration Inhibition
- Reduces the risk of shale hydration and resultant wellbore collapse.
Drilling Efficiency Enhancement
- Improves drilling efficiency by reducing torque and drag.
