The 2012 China Mineral Resources Report, which comprehensively reflects comprehensive information on China's annual mineral resource reserves, exploration, development, markets, and mineral resources management policies, shows that in 2011, the Ministry of Land and Resources Management focused on ore-breaking strategic actions and conducted in-depth exploration of geology. Prospecting new mechanisms, strengthening geological surveys and mineral exploration, improving and standardizing the mining rights market, and making great progress in the exploration and development of mineral resources and their management. The "Report" was first published in bilingual form and will be released at the China International Mining Conference.
The "Report" disclosed that China's investment in mineral exploration has maintained growth, and major progress has been made in the exploration of coal, petroleum, natural gas, iron, copper, tungsten, molybdenum and gold. The investment in exploration in 2011 was 111.82 billion yuan, an increase of 9.2% year-on-year. Among them, the investment in oil and gas exploration was 67.47 billion yuan, an increase of 9.4% year-on-year; the investment in non-oil and gas exploration was 44.35 billion yuan, an increase of 9% year-on-year. Petroleum has added 1.3 billion tons of proven geological reserves and 722.5 billion cubic meters of natural gas. Coal has newly identified 749 million tons of resource reserves, 718 tons of gold ore, and 5.8 million tons of molybdenum. By the end of 2011, the recoverable reserves of petroleum surplus technology was 3.24 billion tons, and natural gas was 4.02 trillion cubic meters; the coal identified 1.38 trillion tons of resource reserves, 74.39 billion tons of iron ore, 86.12 million tons of copper ore, and 3.87 billion tons of bauxite. Gold 7,419 tons.
The output of mineral products such as coal, crude steel, and cement ranks first in the world, and the supply capacity of domestic mineral products continues to increase. In 2011, the country’s primary energy production was 3.18 billion tons of standard coal, a year-on-year increase of 7%, and the energy self-sufficiency rate was 91.4%. Raw coal output reached 3.52 billion tons, an increase of 8.7%; crude oil 204 million tons, an increase of 0.3%; natural gas 103.06 billion cubic meters, an increase of 8.7%; iron ore 1.33 billion tons, an increase of 27.2%; crude steel 680 million tons, an increase of 7.3% .
Foreign trade in mineral products is active, and some big minerals are highly dependent on foreign countries. In 2011, the mineral trade volume was USD 957.1 billion, an increase of 34.3% year-on-year. Imports of major shortages of minerals such as petroleum, iron, and copper continued to grow, and foreign dependence remained high. Among them, oil accounted for 56.7%, iron ore 56.4%, copper 71.4%, potash 51.5%, and aluminum 61.5%.
Strengthen the conservation and comprehensive utilization of mineral resources and develop green mining. The central government has rewarded 704 mining companies for their outstanding achievement in the conservation and comprehensive utilization of mineral resources, and has established 408 demonstration projects in the field of comprehensive utilization of mineral resources. The first batch of 40 comprehensive utilization demonstration bases were deployed and deployed. The Ministry of Land and Resources commended 98 excellent enterprises for the conservation and comprehensive utilization of mineral resources, and selected and introduced to the society 62 advanced technologies involving the selection and comprehensive utilization of oil and gas, coal, metals and non-metals. To promote the development of green mining, two batches of 220 units have been selected and pilot construction work has started.
The level of basic geological surveys has been continuously improved, providing excellent services for economic and social development.
In the key metallogenic belt, major geological problem areas, important economic areas and major engineering construction areas, vigorously carry out regional geological surveys. The country has completed a total of 1.25 million regional geological surveys of 5.67 million square kilometers, accounting for 59.0% of the land area of ​​the land. 1 : 50,000 regional geological surveys 2.37 million square kilometers, accounting for 24.7% of land area of ​​the land. For the first time, the National Geological Archives has released more than 1,600 digital maps of the public scale in the public scale to the public, further strengthening socialized services.
In-depth assessment of mineral resource potential, and further clarify the resources of the family. The focus is on mineral prospects in 19 key metallogenic belts such as the Tianshan-Beishan, Altai, Qilian, Bangonghu-Nujiang, Daxinganling and middle and lower reaches of the Yangtze River. Completely completed the assessment of the resource potential of 13 minerals including coal, uranium, iron, copper, aluminum, lead, zinc, tungsten, antimony, gold, rare earth, potassium, and phosphorus. The evaluation of copper resource potential indicates that the estimated resources for the 500 meters to shallow areas in the country are 192 million tons, 1,000 meters to 274 million tons, and 2,000 meters to 306 million tons. The petroleum geological resources in Northeast China amounted to 22.5 billion tons and natural gas was 4.55 trillion cubic meters. The geological resources potential and recoverable resource potential of China's onshore shale gas are 134 trillion cubic meters and 25 trillion cubic meters respectively.
The order of mineral exploration and development is continuously regulated, and the management of mineral resources is further improved. We promoted key link reforms and institutional innovations, launched trials for the examination and approval of management reforms for coal mining rights, and promoted pilot reforms of mining land use in Pingguo Bauxite Mine, Shanxi Pingshuo Open-pit Coal Mine, Inner Mongolia Erdos Open-pit Coal Mine and Yunnan Phosphate Open-pit Phosphorus Mine. The “Project of Innovation in the Geological Theory of the Qinghai-Tibet Plateau and Major Breakthroughs in the Prospecting Project†won the National Special Prize for Scientific and Technological Progress, with significant social and economic benefits, and the ability to support science and technology has been continuously enhanced. The continuous improvement of China's mineral resources management capabilities and the prosperity of the mining industry have not only effectively supported the stable development of China's economy, but also contributed to the continued development of the global mining industry.
Product Description
Brief Introductions of Reaming Shells
Reaming shell is used to couple the drill bit with the core barrel. It is suitable for use on all conventional and wireline core barrel. This product is mainly designed to ream the hole to the standard diameter. It can keep the stability of the core barrel. When the old bit is replaced by the new one, reaming shell can also provide sufficient clearance for the new bit. It can also help to resist the abrasion of the core barrel. This type of diamond tool is physically longer than the standard type. So for the compensation of the difference in reaming shell length, an appropriate inner tube extension is necessary to be used.
Ranging from broken and abrasive to consolidated and non-abrasive formations, reaming shells are all suitable to use.
Features of Reaming Shells
1) Acts as a stabilizer for drill bit.
2) Be set with natural or synthetic diamond.
Our reaming shells enjoy the best quality and most special design in the industry. With several different types, we try our best to satisfy any of your requirements.
