" 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.

Tungsten market : Tungsten Market demand remained weak , with the looming cost ore prices , increased market inquiry thinly traded , but most will ship hold stocks at a loss is very low, and some even want to lower the average cost of low-cost procurement . Tungsten carbide market overall performance deserted , extremely light volume , few manufacturers received inquiry , and many more before production orders based on the market only a small turnover . Recent tungsten prices are expected to climb by this support and maintenance of stability .

Molybdenum market : This week domestic molybdenum products market generally stable , trading not active , manufacturers cautious. Due to sluggish trading businesses , and the new demand has not timely admission , the market outlook is expected to start generating business disagreements , sometimes cheap deal surfaced . However , many businesses choose to hold stocks in the pre sidelines . Molybdenum market or expected short-term maintenance of stability .

Tungsten concentrate downstream market continued weak demand , ample market supply , sluggish sentiment continued shrouded tungsten City . It is understood that the current market price closer and closer to 105,000 yuan / ton , the market reported high reduction of tungsten concentrate is expected to short-term market or weak stability maintenance, post- market price range or slightly high callback .

Despite the recent part of the business would like to take the opportunity to purchase low-cost tungsten concentrate , therefore inquiry has increased, but buyers are trying to lower prices , then hold stocks for the second half of the market also have certain expectations, cheap shipping will is not strong , the actual the deal less , buyers and sellers on price stalemate each other , resulting in spot transactions continue to be difficult .

This week the market's overall performance tungsten carbide deserted , extremely light volume , manufacturers received little inquiry , and many more before production orders based, only a small amount traded on the market. Analysis of tungsten concentrate raw material prices continue to believe now running low , tungsten demand is low , the manufacturer is not strong enthusiasm for production , short-term or tungsten market remains in the doldrums run .

It is understood that the current market price is slightly confusing, mainstream quotations concentrated in 266-268 yuan / kg , there are very price conscious individual manufacturers are relatively strong, still strong at 270 yuan / kg , the actual transaction is the main focus at 265 yuan / kg.

Recent Russian wolframite 50-55 % of the local tax rates remain at $ 295-305 / t degrees , the export price of 270 U.S. dollars / metric ton . Due to weak downstream demand , tungsten concentrate market turnover is not active , the business is not optimistic .

Russia, a monthly demand of 100-150 tons of tungsten concentrate consumption , traders said they received a current supplier wolframite 50-55 % of the tax price at $ 295-300 / t degrees, compared to the previous price without significant changes . Since they still hold some inventory , replenishment no intention in early April . "The current market wolframite 50-55 % of tax quoted at $ 295 / tonne , vendors refused to less than $ 295 / metric ton ship, " he said, adding that the current market supply , supply intense competition between providers , and the demand is not active , the latter price may be slightly lower number .

Another approximately 100 tons of tungsten concentrate on trading traders reflect recent manufacturer wolframite 50-55 % of the tax price at $ 295-305 / t degrees , the export price in $ 270 / ton degrees , relatively stable. He also said : April Scheelite Russian local market demand is not active , turnover is rare , tungsten concentrate prices or a downward trend ; and the export market is not very Tesco , only a few long single being performed , rarely successful conclusion of export transactions .

Tungsten market : tungsten smelter home very price conscious, but the actual turnover of more or less in the offer , and by weak demand dragged down , only a small amount of turnover . Sodium tungstate market performance light, tungsten concentrate difficult market turnover continued weakness in demand , volume was light, weak market stability maintenance , businesses generally considered short-term outlook is not optimistic, but constrained by high costs and funding constraints , mostly choose to watch the market . Tungsten scrap market limited supply, weak stability maintenance mainstream market , the market is expected to post or continue to slowly dropping .

Molybdenum market : the current rally has slowed domestic molybdenum products , because many businesses in order to complete the original process, and downstream buyers to buy more cautious attitude , a little to quell market trading fiery atmosphere . Lowering the cost of production is difficult , molybdenum and iron manufacturers offer continues to maintain solid . Steel trick late approaching, expected short-term business outlook is expected to remain optimistic side .

At present , the domestic prices of ammonium paratungstate market volatility is not today , downstream manufacturers demand the release of slow sellers to ship helpless speed slowed . Paratungstate mainstream market quotations concentrated in 17-17.2 yuan / ton , the actual transaction at 16.8-17.1 yuan / ton , basically unchanged from yesterday .

Recent inquiry fewer buyers and pushes prices lower, but the seller will not accept Inquiry basic low-cost , the two sides deadlocked . Manufacturers to maintain normal production rhythm , no clear cut, cut signs. Sodium tungstate market performance light, transaction difficulties , 96% sodium tungstate manufacturers offer more in the 130,000 yuan / ton in the vicinity , but the actual transaction , or slightly lower, at about 12.7-12.9 yuan / ton.
