驱出

Some properties of anionic Gemini surfactants were studied in this paper to obtain a good one to efficiently enhance oil recovery.

本文对合成的Gemini阴离子表面活性剂进行各种基本物化性能和应用性能的研究，希望可以从中筛选出性能较好的用于油田驱油提高原油的采收率。

Scaled criteria for steam flooding scaledmodels can be derived by inspectional analysis or dimensional analysis.

运用检查分析法或量纲分析法可推导出适合蒸汽驱比例模型研究的相似准则。

Due to the different salinity of injecting water, relations between formation resistivity and water saturation show nonsymmetrical shapes of "U","L" or "∽".

水驱过程中岩石电阻率 Rt 与含水饱和度 Sw 的关系随注入水矿化度与原始地层水的差别表现出不同的关系。

By the end of 2002, the Shengli oildom has developed 67 oilfields with 89.9 percent watercut and 76.3 percent of recoverable reserve. Furthermore, watercut of 19 oilfields including Shengtuo, Gudao, and Gudong and so on has exceeded 90 percent.

至2002年底，胜利油区已投入开发油田67个，平均综合含水89.9%，可采储量采出程度76.3%，其中胜坨、孤岛、孤东等19个油田综合含水大于90%，全油区常规水驱特高含水单元339个，动用地质储量15.2×10~8t，占油区动用储量的43.1%。

With it, you can mirror the CD directly into a CD-ROM drive, that is to say you can not release the image to your hard disk or CD-ROM can be re-creates the same as with the drive.

有了它，您就可以把光盘镜像直接变成壹个光盘盘符，也就是说您可以不用把镜像释放到硬盘或者再刻出光盘就可以当做光驱壹样用了。

Compare with conventional two-stage settling process, air sparged hydrocyclone has many advantages, such as high oil removal effi-ciency, short settle time; it has a good application prospect.

在过滤技术方面，针对亲油性滤料存在的再生性差、易污染等问题，开展了亲水性纤维球过滤三元复合驱采出污水研究。

In the high efficiency oil removal technology aspect, the theory study and application experiment of air sparged liquid-liquid hydrocyclone was carried out, enlightened by the air sparged solid-liquid hydrocyclone. Firstly, the strength and movement of dispersed phase was analyzed in theory, it was proved that the air bubble-oil drop polymer trend to move to the axes of hydrocyclone. Secondly, using CFD method, the characteristics of oil-air-water flow field were studied, including velocity distribution, pressure distribution, turbulent motion energy and its dissipation distribution. The characteristics and separation effect under different air injection methods were simulated. Thirdly, the separation ex-periment of air sparged liquid-liquid hydrocyclone was carried out at Lab. The major structure parameters of the hydrocyclone were optimized, the reasonable air injection method and performance parameters were determined through 4 groups of air injection experiments.

首先，对气携旋流场中分散相粒子的受力及运动进行了理论分析，证明了气泡与油滴形成的聚合体，更易于向轴心运动；其次，应用CFD方法，研究了油-气-水三相流场的速度分布、压力分布、湍动能及其耗散率分布特性，对不同注气方式的流场特性及分离效果进行了数值模拟；第三，开展了气携液-液旋流分离特性室内研究，优化了旋流器的主要结构参数，对四种注气方式的分离效率进行了对比，确定了合理的注气方式和操作参数；最后，在油田现场开展了处理聚驱采出污水工艺试验，确定了工艺运行参数，评价了处理效果。

Now the factory production, technical management of nearly 100 people, the annual output has reached 30 million and above, the main products are: sassafras oil, according to Ye oil, camphor oil, refined camphor powder, particularly since 2000, by Dian " Zhangmu town "exceptional natural resources, developed the" Evergreen card "pure natural anti-environmental safety of ants Fangzhu series of products, the product not only for all types of borers have killed a special role, but also to have termites Flooding killed function better.

厂内现在生产、技术管理人员近100人，年产值已达3000万以上，主要产品有：黄樟油、按叶油、樟脑油、精制樟脑粉等，特别是2000年以来，我们赁借&樟木之乡&这一得天独厚的自然资源，研制开发出&长荣牌&纯天然环保安全型灭蚁防蛀系列产品，该产品不仅对各类蛀虫有特别的灭杀作用，而且对白蚁有较好的驱杀功能。

If your CD-ROM drive does open, you should also use a spyware product to check your system.

如果你的光驱确实弹出的话，你还应使用一种间谍软件来检查你的系统。

Few days ago, my computer system went wrong. I asked one of my friends who know computer pretty well.He said that he needed to load a CD, but there was no I thought it was not convenient.Another example was that my brother likes to play BIOHAZARD 4

而且前端时间我的电脑系统出了问题，我问一个懂电脑的朋友，他说要装一个光盘进去，可是我的电脑没有光驱，我觉得还是有的时候不方面。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
