Product Advantages

1.Superior Material & Versatile Specifications:

Available in multiple high-quality steel grades (J55, N80, L80, P110) and outer diameters (2 3/8", 2 7/8", 3 1/2", 4 1/2", 5 1/2"), ensuring compatibility with diverse wellbore designs and structural strength requirements.

2.Enhanced Wear Resistance:

Features a robust tungsten plating (over 30μm thickness, 450-550HV hardness) with flexible plating options (internal plating or internal & external plating), forming a durable protective layer to minimize wear and extend service life.

3.Reliable Connection Performance:

Compatible with EUE, NUE standard threads, and special thread designs, ensuring secure, leak-proof connections with downhole tools for stable operation.

4.Exceptional Corrosion Resistance:

Core technical strength lies in its ability to resist harsh corrosive media, including chloride ions, hydrogen sulfide, and carbon dioxide, making it ideal for harsh downhole environments.

5.Broad Application Range:

Suitable for conventional scenarios (oil wells, water wells, gas wells) and excels in complex, demanding conditions such as geothermal wells, thermal recovery wells, and highly corrosive wells, offering versatile solutions for various energy extraction projects.

 

Product Application

Oil Wells:

Provides stable structural support and sealing performance in conventional oil extraction operations. Its high-strength steel grades (J55, N80, etc.) and secure thread connections (EUE, NUE, special threads) ensure durability under typical downhole pressures and mechanical stresses.

Water Wells:

Withstands the long-term contact with groundwater and mineral-rich fluids. The tungsten plating (≥30μm thickness) resists wear from sediment flow, maintaining integrity for extended service in water extraction or injection systems.

Gas Wells:

Performs reliably in gas extraction environments, where tight sealing is critical. Its resistance to hydrogen sulfide and carbon dioxide-common in gas reservoirs-prevents corrosion-induced leaks, ensuring safe and efficient gas production.

Geothermal Wells:

Thrives in high-temperature, mineral-laden geothermal environments. The plating's hardness (450-550HV) and heat-resistant base materials withstand thermal cycling and abrasion from hot brines, extending operational lifespans.

Thermal Recovery Wells:

Adapts to the extreme conditions of thermal oil recovery (e.g., steam injection). Its anti-wear plating resists erosion from high-velocity steam and hot fluids, while corrosion resistance mitigates damage from heated corrosive agents.

Highly Corrosive Wells:

Ideal for wells with aggressive media such as chloride-rich brines, sour gas (H₂S), or CO₂-rich environments. The specialized plating and material composition form a barrier against corrosive attack, reducing maintenance needs and downtime.

FAQ

1.What makes this tungsten-plated oil casing different from conventional casing?

This casing stands out due to its specialized tungsten plating (≥30μm thickness, 450-550HV hardness), which enhances wear resistance and provides exceptional protection against corrosive media like chloride ions, H₂S, and CO₂. Unlike conventional casing, it excels in harsh environments (e.g., geothermal wells, high-corrosion wells) while maintaining structural strength via high-grade steels (J55, N80, etc.).

2.Which steel grade should I choose for my project?

The choice depends on your well's pressure, temperature, and mechanical stress requirements:
J55/N80: Suitable for conventional oil/gas wells with moderate pressure.
L80: Ideal for wells with higher temperature stability needs.
P110: Recommended for high-pressure, high-stress environments (e.g., deep gas wells).

3.Is internal plating sufficient, or should I opt for internal & external plating?

Internal plating works for scenarios where internal wear/corrosion (e.g., fluid flow, sediment) is the primary concern. For wells with external corrosion risks (e.g., contact with corrosive formation fluids), internal & external plating provides full protection.

4.What thread type is best for my downhole tools?

EUE/NUE threads: Compatible with standard downhole equipment in most conventional wells.
Special threads: Recommended for high-pressure, high-temperature (HPHT) wells or projects requiring enhanced sealing to prevent leaks.

5.How long does the casing typically last in corrosive environments?

Thanks to its anti-corrosion plating and high-grade steel, service life is significantly extended compared to unplated casing. In highly corrosive wells (e.g., with H₂S/CO₂), it can last 2-3 times longer than conventional options, reducing replacement frequency.

6.Is the product compliant with international standards?

Yes, our casing meets API (American Petroleum Institute) standards for material strength, thread precision, and performance. It undergoes rigorous testing (pressure, corrosion resistance, hardness) to ensure compliance.
