When it comes to armored well logging cables, the first thing that comes to mind is their robust construction and versatility. These cables are not just any ordinary wires; they are engineered to withstand the harshest conditions, making them the go-to choice for industries that demand reliability and durability. Let's dive into the fascinating world of these cables and explore what makes them so special.
The armored well logging cable is a versatile solution for a wide range of industries. Its robust construction and high-performance materials make it ideal for oil and gas exploration, mining, and geothermal energy production. The cable's ability to withstand extreme temperatures and harsh environments makes it a reliable choice for deep-sea exploration and arctic drilling.
In addition to its physical and electrical properties, the cable is also available in various shielding options, including total shielding and split-phase shielding plus total shielding. This allows users to select the optimal shielding configuration for their specific application, ensuring maximum protection against electromagnetic interference (EMI).
The insulation of these cables is made from modified polypropylene (PP), a material known for its high resistance to heat and chemical corrosion. This insulation ensures that the cable can operate efficiently even in extreme temperatures, ranging from -30°C to 150°C. For those who need even more resilience, there are high-temperature variants that can withstand temperatures up to 260°C. This makes the cable suitable for a wide range of applications, from oil drilling to geothermal exploration.
The steel wire armor is what truly sets these cables apart. The armor is designed to provide maximum protection against physical damage, ensuring that the cable can withstand the rigors of harsh environments. The armor is typically composed of two layers: an inner layer made of 18×0.47 mm steel wires and an outer layer made of 18×0.64 mm steel wires. This dual-layer design not only enhances the cable's mechanical strength but also provides additional protection against corrosion and abrasion.
The physical properties of these cables are equally impressive. The cable diameter ranges from 4.70 mm to 13.20 mm, depending on the number of conductors and the specific application. The cable weight in air is approximately 85 kg/km, making it lightweight yet sturdy. The cable breaking strength is an impressive 13 kN, ensuring that it can handle heavy loads without snapping.
When it comes to mechanical performance, the minimum bending diameter is 260 mm, which means the cable can be easily maneuvered in tight spaces. The cable stretch coefficient is 4.78 m/km/5kN, indicating that the cable can elongate without losing its structural integrity. This is particularly important in applications where the cable is subjected to constant tension.
The electrical performance of these cables is nothing short of remarkable. The voltage rating is 200 VDC, making it suitable for low-voltage applications. The insulation resistance is 500 MΩ·km, ensuring that the cable can maintain high electrical integrity even in humid or corrosive environments. The typical DC resistance at 20°C is 84.3 Ω/km, which is low enough to ensure efficient power transmission.
The capacitance at 1 kHz is 190 pf/m, which is ideal for high-frequency signal transmission. This makes the cable suitable for applications that require precise data transmission, such as seismic surveys and well logging.
For applications in corrosive environments, such as hydrogen sulfide (H2S) rich areas, the cable is available in anti-corrosion variants. These cables are designed to resist chemical corrosion, ensuring long-term reliability even in the most challenging conditions. The ordinary steel armor is also available for less corrosive environments, providing a cost-effective solution without compromising on performance.
