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%.

Currently, Tahe Oilfield simplify a large group of well structure made ​​of three open wells, such wells type II opened up long naked eye 4500-4800m, in the current drilling cycle is extremely tense situation, two open drilling speed appears particularly important, some of this work area well team using a non- standard carbide drill ( 5 " ,5 -1/ 2" ) for drilling , to increase displacement to meet the needs of the upper strata drilling .

In addition , there is the old well sidetrack section 7 "casing to the wellhead window wells, such wells if full well section using 3-1/2" drill , carbide drill for tensile strength is not a small test, furthermore , small water displacement of small eyes , high pressure pumps , pressure on the ground pipeline is relatively large , it can not meet the needs of carrying sand mine , the introduction of such wells 4 " non-standard drill can be good to alleviate the above mentioned problems .

Are non-standard double shoulder drill pipe drill flood the eye , increase when compared with a conventional drill and the inner diameter of the reduced outer diameter of the joint , thereby reducing the pressure loss and the circulating loop inside the pneumatic drill carbide consumption , larger the water capacity of the eye to improve the efficiency and pumping the drill string , increasing the capacity of the drill string from a variety of cable equipment . Also double step design makes makes more uniform stress distribution at both ends buckle can share the load , reducing the stress concentration at the junction ; improved fatigue resistance , thus prolonging life.

In such drilling site is being used to understand (TK347, TH9211-1, S41-1C2, TH12177CH), such use carbide drill team at the well in good condition . At present, because of the limited number of non-standard drill pipe , can not meet the needs of all wells team .
