Application of cables for oil well exploration:

Exploration cables are dedicated cables for geophysical exploration operations. It is widely used in petroleum, hydropower, coal, metallurgy and engineering geology field operations to transmit signals; In addition, our company's exploration cables can also be used as special cables for geological drilling and exploration wells. It is mainly used to measure the top angle and azimuth angle of various geological boreholes in chemical engineering, hydropower, coal, petroleum, metallurgy, nuclear industry and other engineering departments, as well as the transmission of downhole logging signals.

Features

1. This product can adapt to working conditions such as complex terrain, high mobility, frequent sending and receiving, severe weather, and weak signal in field construction;

2. According to user requirements, special exploration cable series products with different numbers of channels, different spacings, different lengths, and different environmental requirements can be produced;

3. The special structure design of our company's exploration cable has high flexibility, bending resistance, good insulation performance and strong anti-interference performance. In addition, the product is also very resistant to wear, cold, oil, non-fading, discoloration, waterproof, tensile, and anti-aging;

4. Multi-core can choose small pitch pair twisting to effectively improve the crosstalk defense; In addition, the shielding structure of the cable covered with high-density mesh copper wire and tin-plated copper wire is dense, high conduction rate, and high response rate. To shield and filter interference with the largest absorption and fastest conduction to ensure the smallest interference of the transmitted signal;

5. Environmental protection standards, select high-quality raw materials to process exploration cables to ensure that all testing indicators of the cables meet the national environmental protection standards;

6. It is proved by users that its mechanical performance, electrical performance and waterproof performance can meet the requirements of field operations.

The structure of the cable

Conductor: multiple strands of finely stranded, soft, oxygen-free bare copper wire / tinned copper wire (the conductor material is optional)
Insulation: high-quality PE material insulation, with good electrical insulation and waterproof performance.
Color: core wire color identification, brown, black, blue, purple, pink, orange (core wire color can also be customized)
Inner shield: braided shield wrapped in aluminum foil Mylar and tinned copper mesh.
Filling: imported polyfluoro yarn (flame retardant and fire resistant).
Drain wire: (optional) The drain effect of the same specification as the conductor, which is convenient for the shielding processing of the wire harness.
Cable formation: Optimize the stranding pitch of the cable, and the multi-core can be twisted first and then optimized into the cable.
Shield: braided shield of bare copper wire or tinned copper mesh (optional)
Density: 85% or more
Sheath: Imported PUR sheath orange, green, black or gray.
