Continuous Tubing Equipments

Our high-performance ‌Coiled Tubing Equipment‌‌ is engineered for critical oil & gas well interventions, delivering ‌15,000-psi pressure integrity‌ and ‌automated depth control‌ via safety-rated PLC systems. It solves the pain points of operational inefficiency and frequent maintenance in conventional workover methods, providing bulk purchasers with ‌40% faster deployment‌, ‌30% reduced downtime‌, and ‌API 5ST-compliant reusable tubing strings‌ for sustained cost efficiency.

Coiled Tubing Equipment refers to a series of professional downhole operation equipment specially developed for oil & gas exploration and development. It integrates coiled tubing, injection head, winch, control system and safety protection devices. This equipment, widely used in well completion, workover, fracturing, acidizing and other oilfield operations, can meet the high-standard and efficient operation requirements of oilfield enterprises and project parties.

As a professional manufacturer of Coiled Tubing Equipment, we focus on creating efficient, safe and durable downhole operation solutions for global purchasers. We adhere to the EEAT principle to ensure that every set of equipment meets international industry standards and user actual needs. Our Coiled Tubing Equipment adopts high-strength alloy steel and anti-corrosion materials, which are carefully selected through strict raw material screening procedures. Each batch of materials must undergo tensile strength, pressure resistance, corrosion resistance and other 10 professional tests, with a qualified rate of 100%. This ensures the stability and service life of the equipment under high-pressure, harsh downhole environments.

From the perspective of product features (F), our Coiled Tubing Equipment adopts a modular integrated design, featuring a high-efficiency hydraulic injection head and intelligent PLC control system, with an injection speed of 0.5–5 m/min and a maximum working pressure of 105 MPa. This design effectively avoids the low efficiency and high failure rate problems that often occur in traditional downhole operations.

1. Coiled tubing well completion‌ is deployed in horizontal, directional, and vertical wells for critical operations including:

• Production tubing installation
• Wellbore cleanout prior to completion
• Open-hole gravel packing for sand control

The ‌continuous spooled tubing system‌ performs these tasks in a single trip without pipe connections, reducing completion time by 40% and eliminating 90% of contamination risks associated with conventional methods. This technology is indispensable for deep and ultra-deep wells with complex conditions (e.g., high-pressure/high-temperature reservoirs) where traditional pipe handling becomes impractical. Engineered to ‌API SPEC 5ST standards‌, it ensures completion integrity while maximizing operational efficiency .

2. ‌Coiled tubing operations‌ are extensively deployed in well intervention tasks, including ‌sand washing, scale removal, wax cleaning, and fishing operations‌ for oil & gas wells. The ‌flexibility and continuous spooling capability‌ of coiled tubing enables it to navigate through deviated wellbore sections while minimizing wall damage. This technology efficiently resolves well blockages and equipment failures, reducing workover costs by up to ‌30%‌ and extending well service life through ‌reduced formation damage‌ and ‌API RP 5C7-compliant procedures‌.

3. Coiled Tubing Hydraulic Fracturing & Acidizing‌
Utilizing continuous spooled tubing for pinpoint fluid delivery in low-permeability reservoirs (≤1 mD), this technology enables:

• Precision staged stimulation‌ via real-time downhole tool manipulation
• Dynamic diversion control‌ for uniform fluid distribution across heterogeneous zones
• Zero-kill fluid operations‌ preserving reservoir pressure (API RP 5C7 compliant)

Compared to jointed-pipe methods, coiled tubing achieves:
✓ ‌30% higher placement accuracy‌ in lateral wells (>3,000m MD)
✓ ‌45% reduction in fluid loss‌ through controlled injection rates
✓ ‌2.7x production uplift‌ in tight gas formations (measured after 180-day flowback)

4. Optimized Technical Description: Coiled Tubing-Conveyed Well Testing & Logging‌

‌API-Compliant Real-Time Reservoir Characterization‌
Our coiled tubing systems integrate with downhole tools to perform precision reservoir evaluation under live-well conditions. The continuous spooled tubing provides:

• Stable tool conveyance‌ to target depths ≤8,000 m TVD with ≤0.5° deviation
• Real-time fiber-optic telemetry‌ for simultaneous acquisition of pressure/temperature/gamma ray data (per ‌API RP 5C7 §9‌)
• Dynamic fluid sampling‌ at 20+ zones per run with zero formation damage
