The National Machine God to Refresh the Largest Drill Depth Record in China

Recently, by the National Machine Group China Geological Equipment Group Co., Ltd. (hereinafter referred to as the "Chinese loading company") developed the first domestic XD35DB-type AC variable frequency electric top-drive geological core drilling rig, in the Xiangshan area of Jiangxi Province, the implementation of the Chinese uranium mine 3000 meters scientific deep drilling project drilling depth exceeded 2000 meters, creating a domestic 150 mm rope diameter heart drilling depth record, reached the international advanced level of similar products. The implementation of the project is another successful cooperation between China National Aircraft Group and China Nuclear Group. This breakthrough in technology and engineering projects has expanded the prospecting space of uranium resources in China and laid the foundation for further expansion of uranium resources.

This sensational drilling industry's AC variable frequency electric top-driven core drilling rig, formerly known as the 2012 mid-pack company and China Nuclear Group jointly developed xD35DB geological core drilling rig, the equipment has also created Herculean war work. In 2013 in the "China's first scientific deep drilling project" in China to create a 2818.88 meters (122 mm diameter) drilling depth of domestic heart-to-heart drilling record, broke through the then 1200 meters of uranium ore prospecting depth, to fill the deep uranium mining in China to find the gap, shorten the gap between China and foreign uranium exploration.

Since then, the company has made an innovation and upgrade to the XD35DB top drive system, and loaded the XDZ40DB-type AC-variable-all-in-one direct drive top drive device developed by the National High-Tech Research and Development Program to achieve product upgrades. The upgraded XD35DB, which integrates electricity, liquid, gas and information technology, greatly improves the level of intelligence, digitization and automation of drilling equipment, fills the gap in the country, leads the development direction of deep drilling equipment, and finally sets a new record of 150 mm drilling depth in 2020.

In recent years, China's energy industry has shifted from high-speed growth to high-quality development stage. With the extension of the drilling depth of resources and energy exploration, the drilling construction time is long, the cost is high and the risk is high, which puts forward higher requirements for drilling equipment and drilling process. Around the application of large-depth geological equipment technology development, the company to the deep earth into the heart of the first heart, continue to make efforts in scientific and technological research and development.

The company took the lead in the "13th Five-Year Plan" national key research and development program topic "5000 meters geological core drilling rig key technology and equipment development", in accordance with the overall requirements of the project, around the whole process column automation operation of more than 90% of the goal, the tube column automation device research, and the core system - the top drive system for a new round of system upgrade. This research can improve the efficiency of operation, reduce the operational risk, avoid drilling accidents, and realize the stage leap of drilling rig automation process.

"Forging the director of the national machine, serve the country needs", the national machinery group party secretary, chairman Zhang Xiaolun in the research of the company stressed that in geological equipment to reduce dependence on foreign products, practice the responsibility and responsibility of the central enterprises, play a "national team" prominent role.

In the future, China Equipment Group will aim at national strategic requirements and industry needs, continue to "deep into the earth" on the road, to open up a new pace of high-quality development.
