Abstract:Continued growth in energy demand, prevention and control of environmental pollution, and response to climate change require accelerated energy structure adjustment. Marine geological surveys are urgently required to provide new target areas for oil and gas exploration and development, which provide basic support for the commercial exploration and development of natural gas hydrates. China’s independently designed and built Marine Geology-10 Ship fills the gaps in our country’s small tonnage and large deep marine geological drilling ships, which enhances our marine geological survey capabilities, and marks China’s comprehensive marine geological survey capabilities are among the best in the world and provides valuable experience for the future ocean drilling. The drilling system of Marine Geology-10 Ship uses different coring tools for different strata, and successfully completed drilling A and B holes for coring work in a South China Sea region. In view of the risks of marine drilling operations, the countermeasures formulated by Marine Geology-10 Ship have ensured the normal drilling operations. Practice has proved that the drilling system of Marine Geology〖KG-*8〗-〖KG-*8〗〖KG*9〗10 Ship successfully completed the coring work of marine geological drilling.
