FAQs

Q1: What is a load bearing exploration cable used for?

Load bearing exploration cables are mainly used for oil & gas well logging, perforating, coring, and other downhole operations. They provide load bearing, power supply, signal transmission, and depth measurement functions.

Q2: What core types are available for load bearing exploration cables?

According to the number of cores, the cables are available in single-core, three-core, four-core, and seven-core structures to meet different downhole operation requirements.

Q3: What temperature range can load bearing exploration cables withstand?

Normal temperature cables usually operate from -30°C to 150°C, while high-temperature load bearing exploration cables can withstand temperatures from -50°C to 260°C.

Q4: What is the difference between ordinary and sulfur-resistant exploration cables?

Sulfur-resistant load bearing exploration cables are specially designed for corrosive oil & gas wells containing H₂S and other harsh media, offering enhanced corrosion resistance and longer service life.

Q5: Which standard do load bearing exploration cables comply with?

Load bearing exploration cables are manufactured according to SY/T 6600-2020, the oil and gas industry standard for load-bearing exploration cables.
