China's load-bearing probe cable "dives" into the 10,000-metre deep sea
2018-03-30
By international cooperation, the development of oil and gas exploration with 10,000 metres of load-bearing detection cable, has been successfully "submerged" to the 10,000-metre deep sea. The technology fills the technical gap in China in the 10,000-metre detection depth, breaking the foreign technology monopoly on the armouring of ultra-long load-bearing detection cables, the cost is also lower than the imported products by about 20%.
The scientific community of the ocean depth of more than 6,000 metres of the region known as the "abyss", with far more than the ground's enormous pressure, 10,000 metres under the sea, the unit square metre area will be subjected to more than 10,000 tons of pressure. Seawater has a very strong corrosive, in such deep water "work" of any equipment, need to be extremely strong pressure corrosion resistance and tough performance. At present, in the field of marine engineering and oil exploration, for load bearing probe cable armour with steel wire strength, toughness and corrosion resistance and other requirements are increasingly high. In the past, the technology of ultra-long load bearing probe cable armouring, in the hands of the United States.
Ltd. is a national key high-tech enterprise and "science and technology small giant enterprise" with more than 40 years of cable production history. Since 2014, the company began the offshore engineering and oil and gas exploration load-bearing probe cable armouring with steel wire project research and development, and with the use of micro-nanometer scale (50-100nm) bainite structure, with Nb microalloying grain refinement, slowing down the decarburisation of the heat treatment process, the success of the development of ultra-high-strength (2,260MPa), high-toughness cable armouring Steel wire, to meet the requirements of complex logging conditions, to achieve load-bearing probe cable and carrying exploration robot (carrying Cobalt-60) in the ultra-deep wells in the vertical section and the horizontal section of the operational safety.
The reporter learnt that, because the load-bearing probe cable is operated under repeated tension winding conditions, the service life of the product in the past was only 100 wells, that is, it can only be used about 100 times at sea. And Huaneng load-bearing detection cable, the service life increased to 120 wells, reducing the cost of oil exploration. At the same time, it makes China's deep well or deep sea detection ability reach or even break through 10,000 metres, increasing the exploration space for ocean engineering and oil and gas exploration. The achievement won the International Cooperation Award of Jiangsu Province.
At present, load-bearing detection cable has been in this year, will achieve high strength, high toughness, corrosion resistance oil and gas exploration load-bearing detection cable armoured steel wire localisation, to meet China's oil and gas 10,000 meters deep sea exploration needs.
