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 .

Tungsten market : weaken the mainstream market today tungsten , tungsten scrap business mentality gradually confused , pessimistic market outlook is expected to partial operation less active . Although some manufacturers aimed at very price and offer strong, but still none the actual transaction . Market turnover of more low, especially raw tungsten concentrate and paratungstate decline more obvious because it is difficult to even lower offer to ship the material this week tungsten or no improvement in the city , continuing a steady weak to run.

Molybdenum market : current domestic product molybdenum price gains more fierce , more molybdenum concentrate , molybdenum, iron and other businesses to improve the product outside offer . In addition , the European molybdenum commodity prices remain on the very trend of demand in good condition. Post-market trend is unknown, downstream buyers waiting to see more, so much the actual high turnover phenomenon . Short-term molybdenum market is expected to run on the strong side .

According to Jiangxi Provincial Price Monitoring Authority to identify price monitoring : March , Ganzhou high yttrium oxide ( REE) , yttrium europium compounds ( RE ) retail price of 210,000 yuan per ton , respectively, and 20 million were flat year on year respectively. fell 16.00 percent , 13.04 percent ; Ganzhou retail price of 118,000 yuan per ton tungsten concentrate , fell 1.66 percent , down 3.28 percent .

Tungsten concentrate prices continue dropping close to cost price , coupled with lower powder sluggish demand for ammonium paratungstate , ammonium paratungstate factory orders are leading this week paratungstate sharp decline in prices , the current cash has fallen below 170,000 mark, and turnover continued to light, is expected to post the risk of price or still dropping . It is understood that the current APT cash transaction price and more concentrated in the 168,000 yuan / ton in the vicinity , mostly in acceptance transaction price between 17-17.2 yuan / ton, quoted Foreign manufacturers in order to compare prices very strong, concentrated in the 17.3-17.5 Million / tons.

Meanwhile, the market performance of sodium tungstate quiet transaction difficulties , the overall market demand is not strong, which is mainly due to sluggish downstream demand and lower raw material market . However , manufacturers now offer almost flat areas , because it is difficult to even offer lower shipping . It is understood that the current mainstream market quotations are 132,000 yuan / ton in the vicinity , but the actual turnover of more has fallen below 130,000 mark. Businesses operating enthusiasm is not strong, the market waiting to see atmosphere thick .
