Academician Xie Heping's deep-sea thermal insulation and pressure coring prospecting research team participated in the sea trials of the Warriors.
China Economic Herald, China Development Network News Ni Jun On September 23, the deep-sea sediments ( natural gas hydrate) thermal insulation and pressure-holding sampling independently developed by the Shenzhen University and Sichuan University teams led by Academician Xie Heping The equipment has been successfully tested at sea, and this is also the first time in the world to obtain an in-situ fidelity sample of deep-sea sediments (natural gas hydrates) with thermal insulation and pressure retention.
The national major scientific research instrument development project "Deep rock in-situ fidelity coring and fidelity test and analysis system" chaired by Academician Xie Heping has successfully developed a deep-sea sediment (natural gas hydrate) thermal insulation and pressure-holding sampler after several years of research. . On September 23, 2022, the deep-sea sediment (natural gas hydrate) thermal insulation and pressure-holding sampler was mounted on a 4,500-meter-level in my country under the "Deep-Sea Abyss Scientific Expedition and Equipment Sea Trial Shared Voyage" organized by the Hainan Deep Sea Technology Innovation Center. The manned submersible "Deep Sea Warrior" completed the set task in the 1370-meter water depth area of the South China Sea, and obtained deep-sea sediment ( natural gas hydrate ) samples with an in-situ pressure of 13.8 MPa and a temperature of 6.51 °C, breaking through the deep sea The technical problem of sediment (natural gas hydrate) pressure-holding sampling technology has overcome the world gap in deep-sea sediment (natural gas hydrate) thermal insulation sampling technology, and achieved a breakthrough in the acquisition of zero thermal insulation and pressure-holding sediment (natural gas hydrate) samples in the world.
Since 2018, the team of Academician Xie Heping has been devoted to the research of deep in-situ fidelity coring and fidelity testing technology and equipment. my country's first set of deep-sea sediment (natural gas hydrate) thermal insulation and pressure-holding sampling, in-situ fidelity displacement, and in-situ fidelity testing complete sets of equipment with intellectual property rights have formed a new principle and technology system for deep-sea material resource fidelity exploration, realizing deep-sea material resources fidelity exploration. Localization and autonomy of prospecting technology and equipment.
The successful deep-sea in-situ fidelity sampling marks that my country's deep-sea sediment (natural gas hydrate) thermal insulation and pressure-retaining coring technology has reached the world's leading level, providing technical equipment support for my country's deep-sea resource exploration and development and marine scientific exploration.
