Product Description
This Economical Wellbore Stabilizer Sulphonated Asphalt is a multi-functional organic drilling fluid additive designed to inhibit shale hydration, reduce dispersion, and control high-pressure high-temperature (HPHT) filtration loss in water-based and oil-based mud systems. Composed of a balanced blend of water-soluble and oil-soluble components, this dark brown powder readily dissolves in water and adsorbs onto shale crystal layers, effectively preventing hydration-induced dispersion and wellbore collapse. Its insoluble fractions act as a physical plugging agent, sealing micropores and fractures in the formation while improving filter cake quality. Additionally, this Economical Wellbore Stabilizer Sulphonated Asphalt enhances lubricity, reduces torque and drag, and minimizes fluid invasion into shale formations, making it ideal for high-temperature and high-pressure drilling applications.
Applications/Functions
Reduces HPHT fluid loss in water-based and oil-based drilling fluids;
Stabilizes shale formations by inhibiting hydration and dispersion;
Seals micropores and fractures to prevent wellbore collapse and fluid invasion;
Improves lubricity and reduces friction in deviated and horizontal wells;
Enhances filter cake quality and wellbore integrity.
Advantages
Functions as a multi-purpose additive: plugging, anti-collapse, lubrication, and inhibition;
Thermally stable up to 350°F (177°C), ensuring performance in high-temperature environments;
Forms a thin, tough, and low-permeability filter cake to strengthen the wellbore;
Compatible with other drilling fluid additives, including polymers and lubricants;
Cost-effective solution for complex drilling operations;
Exhibits excellent emulsification properties and environmental adaptability.
Typical Properties
Appearance: Dark brown to black free-flowing powder
Specific Gravity: 0.98
Recommended Treatment
A typical dosage range of 2–8 ppb is recommended, depending on well conditions and fluid system requirements. For severe shale instability or high-temperature environments, the dosage may be increased to 10 ppb. Add the Economical Wellbore Stabilizer Sulphonated Asphalt gradually during fluid mixing to ensure uniform dispersion and optimal performance.
Packaging & Storage
Packaging: 25 kg sacks, with an outer brown paper bag and an inner moisture-proof plastic liner.
Storage: Store in a ventilated, cool, and dry place to prevent moisture absorption and caking. Avoid exposure to rain or high humidity.
FAQ
Q: What is liquid asphalt also known as?
A: Bitumen, also known as "liquid asphalt cement" or simply "asphalt", a viscous form of petroleum mainly used as a binder in asphalt concrete.
Q: Is liquid asphalt good for waterproofing?
A: Liquid asphalt is widely used for waterproofing in construction due to its durability and versatility. It provides an effective barrier against water, protecting structures from potential damage.
