Intelligent Cable-Embedded Coiled Pipes
The intelligent cable-embedded coiled pipe series includes four products: cable-embedded oil production coiled pipes, cable-embedded water injection coiled pipes, cable-embedded heating coiled pipe, and cable-embedded water production coiled pipes. All of these products, embedded with signal or power transmission cables in the pipe body, use get and transmit data to the data analysis control center through sensors, such as downhole pressure, temperature, fluid level, pump unit operating parameters, wellhead pressure, temperature and flow parameters. The analysis and processing results are sent through the expert system to relevant terminals for real-time monitoring and management. Therefore, the intelligent well site injection, production and transportation are important part to serve as the basic module of the smart oilfield.
It is characterized high strength, corrosion resistance, light weight, low friction resistance, good flexibility, long service life, and good customization, easily construction, intelligent, and low accident rate.
It has obviously advantage such as high strength, corrosion resistance, light weight, low surface friction coefficient, good flexibility, long service life, and good customization, as well as easily construction and intelligence, low accident rate.
High strength: the burst pressure over 120MPa, the collaspe over 30MPa, and the tensile broken force over 400KNs and the higher specification can be designed according to the requirement;
Corrosion resistance: It can bear strong acids and alkalis, suitable for various corrosive environments, especially fluid containing H2S and CO2;
Temperature resistance and heat isolation: The long term operating temperature is ≥85°C, and the comprehensive thermal conductivity coefficient is 0.42W/(m·K), which can reduce the thickness of the insulation layer or even without the insulation layer;
Light weight: It is only half of the steel pipe weight at the same diameter and pressure level;
Low surface friction coefficient: The equivalent roughness is only 0.0015mm , not easy to form scale or wax, 16% higher than the steel pipe flow at the same diameter, and the smooth inner surface can save power consumption;
Good flexibility: The pipe elastic deformation range is 3% , which can compensate the stress caused by pressure and temperature. It can be repeated coiling and de-coiling, and has good adaptability to different condition ;
Long service life: The pipes have passed the 10,000-hours long-term hydrostatic test according to ASTM D2992, and the service life is at least 20 years.
Good customization: Customers can provide the requirement and we design the customersized product, such as heating pipes, anti-wax pipes, anti-scale pipes to improve the transportation efficiency and lower the maintenance cost;
Easily construction: The maximum length of a single pipe is over 2,000 meters, the continous pipe is easily to construction;
Intelligence: The embedded signal cables and sensors or optical fibers can transfer data to the management personal in real time through the communication module, making it possible to control parameters of the downhole liquid level, temperature and submersible pump at any time, and use the mega data platform combined with the internet to construction the smart oilfield;
Low accident rate: Cables, optical fibers and other sensing units are embedded in the pipes, and the pipe lift and down can be finished within one day by using special operation equipment , which greatly improves operational efficiency while reducing cable collisions, cable abrasion and other accidents.
