Tungsten is extremely scarce and irreplaceable strategic resource , but also the national economy and national defense irreplaceable foundation of modern materials and strategic resources , manufacturing tungsten carbide known as "dental industry ," Carbide widely in the areas of military, aerospace, machinery processing , metallurgy, oil drilling , mining tools, electronic communications, construction , etc., is the key material tungsten lighting , electronics and other industries. In these applications, has not yet found a direct substitute for tungsten.

Currently, only the world's total proven reserves of tungsten 2.898 million tons , is extremely scarce resources , more than 20 kinds of the world's known tungsten minerals , industrial value only scheelite and wolframite are two, wolframite are quality tungsten ore, scheelite are refractory ores . China 's tungsten resources abundant , accounting for nearly 70% of the world 's proven reserves of tungsten mineral resources , ranking first in the world .

2010-2013 , equivalent to the amount of tungsten concentrate production increased year by year , and reached its highest level in 2013 , tungsten concentrate production was 138,000 tons .

Through the analysis of primary tungsten and "Twelfth Five Year Plan" according to the analysis of waste tungsten tungsten industry, we assume that the future of native producers of tungsten in tungsten concentrate production quota increase of 1% per year , the 2017 Chinese tungsten concentrate equivalent to the amount of production will reach 143,600 tons .

2014-2017 Chinese tungsten ore market analysis research has been mentioned in the report , domestic demand for tungsten basically showing steady growth in the state . Although the impact of the financial crisis is not over , the European sovereign debt crisis is still spreading and so the constraint of global economic development, but the trend of global economic growth will continue, tungsten demand will continue to grow in 2015 , total global demand may up to 83000t, with an average annual growth rate of 4%.

According to Chinese customs statistics data analysis , in February 2014 Chinese exports to 1,022 tons of tungsten tungsten ( including mixtures ) , a decrease of 31.78% , mainly due to the impact of the Chinese New Year holiday . The first two months of 2538 tons of tungsten exports , an increase of 5.14% . It is understood from the export enterprises, foreign purchases of normal , is still maintaining some of the old customers purchase , purchases have not increased significantly. It is difficult to judge overseas demand has improved, but it does show a growth momentum. January to March is expected to export 4280 tons of tungsten , an increase of 2.5%.

Tungsten can be seen from the number of major export products , APT, tungsten carbide metatungstate and export volume grew , mainly because of improved environmental standards abroad . January-February exports APT477 tons , an increase of 115.92% ; export metatungstate 409 tons , an increase of 304% ; WC 325 tons , an increase of 10.1 %. Tungsten oxide exports still down 1-2 February exports 487 tons of yellow tungsten oxide , down 7.74% ; export 294 tons of tungsten blue oxide , down 3.61 percent .

Judging from tungsten imports , in February 2014 imports 288 tons of tungsten , 1-2 months of imports 695 tons , down 33 % compared to the same period in 2013 . Scheelite tungsten products are mainly imported , accounting for more than 90% of total imports . By weak domestic demand and the impact of oversupply , the first two months of tungsten imports dropped significantly. January to March is expected to import 1,190 tons of tungsten , down 22.3% .

2014 January-February imports 516 tons of tungsten concentrates , which imports 433 tons of tungsten concentrate in Fujian Province , accounting for 84 % of total imports ; Liaoning imported 26 tons , accounting for 5 % of total imports . Guangdong is imported in previous years, the main areas of tungsten concentrate , from January to February this year, almost no imports. Chinese tungsten concentrate imported mainly from Russia, Canada , Rwanda , Bolivia and Vietnam .

" Well past the gas-liquid ratio is very high so that we headache, gas into the pump , not only affects the pump efficiency , and may form a ' air lock ', completely unable to produce oil . " Peng Zhenhua technicians engaged in research of mechanical oil , high anti-gas liquid ratio well that he and his team from the beginning to the start of the research project . "We have developed a new pump with carbide material, the parts are optimized connection , strength and stability is absolutely reliable, down to a depth of 3500-4000 m . "The new confidence of employees Cao Chang added .

For conventional pump can not exhaust tube defects, the researchers initially hoped to increase the local pump barrel diameter to form an effective exhaust space with well fluids to facilitate the timely replacement of gas and timely discharge. After checking through stress analysis and strength , the idea was quickly rejected. Considering the single pump barrel after expanding strength and stability will deteriorate , it was thought at the pump barrel "bridge " , which is equivalent to a single layer of the pump barrel collar locator formed by double pump barrel .

" This ' bridge ' is not our way original, Tahe biggest problem is a deep pumping, the pump must be accepted at any point in this innovative test. " Another major anti- double pump designer Zhang Park said.

Single cylinder through the " bridge " to the double cylinder , the inner cylinder after special processing , there is a partial enlarged diameter cavity formed by the gas-liquid replacement is a chamber , which is anti- double the core of the air pump .

When this special tube pump , with the vertical movement of the plunger , the plunger and the lower portion of the continuous gas liquid piston displacement occurs in the upper portion of the tubing , a lower degree of filling of the plunger is improved , thereby promoting the oil open the valve , which can effectively prevent " air lock " to increase the pumping wells pump efficiency and production time .

It is reported that anti- double pump has AT9-14H, S41-6H and TK515 wells in Tahe Oilfield field test conducted after the test pump efficiency up to 86.8% on average , a single well daily gas production reached 1 Articles , significantly lower than the gas-liquid , currently the longest effective exhaust time reached two months.
