The basis function of the coinjection of Nitrogen and steam is increasing the displacement volume and supply the displacement energy on the basis of Nitrogen, the result of the numerical simulation showed that, after the coinjection of Nitrogen and steam (the optional aqueous Nitrogen ratio was 1: 20～1: 50), the theamal readius increased from 30m to 55m more or less, the recovery ratio increased by 5～10％. The production effect of the high cycles steam stimulation will be improved and the pattern infill will be avoided and the economic results will be improved. 4. The poor result of steamflood is another problem. On the basis of the analysis of the foamer mechanism in the propayation, movement and stabilization, this paper showed that the main meachanism of the increasing recovery of the Nitrogen foam and steamflood was the increasing displacement factor and oil displacement efficiency.

On the basis of same main components, comparison and analysis are performed on thermodynamic performance of HAT cycle, STIG (Steam-Injected Gas Turbine) cycle, gas-steam combined cycle and the relevant cycles with intercooling or reheat.

在主要部件相同的基础上，分析比较了HAT循环、注蒸汽燃气轮机循环、燃气—蒸汽联合循环以及各循环采用中冷或再热手段后相应循环的热力性能，确定了再热HAT循环高效率和中冷再热STIG循环高比功的优势，指出中冷手段对循环性能改善不大，回收中冷热量也不会收到好的效果，而再热手段对循环性能改善显著。

The steam acts upon the surface of the water in the receiver, which surface only being heated by the steam, it does not condense, but the steam gravitates or presses with an elastic quality like air, and still increasing its elasticity or spring, until it counterpoises, or rather exceeds, the weight of the column of water in the force pipe, which then it will necessarily drive up that pipe; the steam then takes some time to recover its power, but it will at last discharge the water out at the top of the pipe You may see on the outside of the receiver how the water goes out, as well as if it were transparent; for, so far as the steam is contained within the vessel, it is dry without, and so hot as scarcely to endure the least touch of the hand; but so far as the water is inside the vessel, it will be cold and wet on the outside, where any water has fallen on it; which cold and moisture vanish as fast as the steam takes the place of the water in its descent.

&&蒸汽行为后，水面在接收端，而只是表面被加热水蒸汽，它不浓密，但相互依赖蒸汽或印刷机具有弹性质量一样的空气，并仍在增加其弹性，或春天，直到它网，而超过重量栏水警队管道，然后它一定会推到管；蒸汽则需要一段时间来恢复其权力，但它会在最后排放水出顶管，你可以看到外面的接收机如何当然水，以及如果它的透明度；，目前为止由于蒸汽载船，它是未经干燥，所以作为热几乎要忍受至少触摸的手；但到目前为止，由于水内的船只，将寒冷和潮湿对外面，那里没有水落下；其中寒冷和水分消失快蒸汽需地方水在其后裔。

The statistics of oil field production indicates that the dryness fraction of the steam heat boiler export is about 75% at present .While the dryness fraction of steam of the steamed well mouth is only about 60%, which affects the effect of steam huff and puff and the economy of thermal production.

Melting point 3410 ℃, boiling point 560 ℃, relative density of 1935, F the external electronic structure of 5d46s2, in the chemical reaction time is very easy to lose 1-6 electronic, but also can get 1-2 electronic, so oxidation number of 0,± 1,± 2, 3, 4 , 5 and 6, with 6 price of the most stable compounds, such as WO3 does not dissolve in water, the air will form in the tungsten trioxide thin protective layer of tungsten, tungsten with fluorine at room temperature, chemical combination, red hot when there is no moisture and Bromine iodide together, red hot when you can and water reaction WO3, at room temperature reaction of tungsten with aqua regia, but the hot concentrated hydrochloric acid and sulfuric acid can only be played with its weak response, but molten nitrate, nitrite, too Hydrogen peroxide, sulfur steam, steam and other phosphorus can play intense reaction, high temperature can not be carbon, boron and silicon reaction of binary compounds, widely used in industrial tungsten steel and tungsten carbide, pure tungsten filament is used to the system, and X-ray tube Tube heating components, semiconductor components can be prepared tungsten silicide, tungsten industrial production is white or black tungsten ore tungsten ore refining.

熔点3410℃，沸点560℃，相对密度1935，F外围电子结构为5d46s2，在化学反应时很容易丢掉1—6个电子，也能得到1—2个电子，所以氧化数为0、±1、±2、＋3、＋4、＋5和＋6，以＋6价化合物最稳定，如WO3不溶于水，空气中的钨会形成薄层三氧化钨保护层，钨能与氟在室温下化合，红热并无潮气时能与溴、碘化合，红热时还能和水反应生成WO3，室温下钨可与王水反应，但热的浓盐酸和硫酸只能与其起微弱反应，但对熔融的硝酸盐、亚硝酸盐、过氧化氢、硫蒸汽、磷蒸汽等能起激烈反应，高温下不能与碳、硼和硅反应生成二元化合物，工业上广泛使用钨钢和碳化钨，纯钨用来制灯丝、电子管和X射线管的发热元件，硅化钨可制半导体元件，钨工业生产是将白钨矿石或黑钨矿石精炼。
