开采

For low permeability reservoir, waterflood development is the most popular method. In waterflooding, the quality of water injection not only has influence on the efficiency of the process system but also on the index and result of oilfield development.

对于低渗透油藏，目前普遍采用的是注水开采的方式，在注水开发中，注入水水质的好坏不仅影响注水工艺系统的效率，同时要影响油藏的开发指标及开发效果。

By analyzing typical examples, waterflood development effect is affected by such factors as reservoir parameters, fluid properties and development scheme.

通过实例计算，研究了低渗透油藏中储层参数、流体特性以及开采方式等因素对注水开发效果的影响。

A waterflood can recover anything from 5-50% of the remaining oil in place that would not have been produced using primary recovery alone.

不知道中国政府怎么想的？居然想在墨西哥湾开采石油，刺激美国。胳膊没有那么粗，跟美国起什么哄？

Fingering often occurs in waterflood development low permeability reservoir because of non-Darcy flow, which is weakened with formation dip increasing.

结果表明，由于非达西渗流的影响，注水开发时容易发生指进现象，而地层倾角的增大可以削弱指进；地层原油粘度的增大会增强开采难度，而地层渗透性能的改善会使油井产能提高。

We also analyze the particular characters that a well-formed distributed data mining system should have in its architecture.

随后分析了分布式数据开采系统的体系结构应该具有的特点。

The introduction of the Newman Hub will mean that the company's Mt Whaleback iron ore operation will be equipped to mine, crush and screen the ore at site rather than those processes taking place in Port Hedland before the product is shipped from Port Hedland.

纽曼采矿中心的成立意味着公司在鲸背山的铁矿开采可以集现场采矿、粉碎和筛选于一体，而不用在产品从黑德兰港启运之前就进行这些工序。

Article 31 Coal production shall be carried out within the approved limits of mining areas according to law.

第三十一条煤炭生产应当依法在批准的开采范围内进行

Sure, why not … Everything goes in the wondrously twisted world of 70's exploitation, right?

当然，为什么不。。。一切都在wondrously扭曲世界70的开采，对不对？

They have been used in many traditional industries,such as leather-making,oil drilling and wood adhesive for years.

多年来它们一直用于许多传统工业领域如制革、石油开采和木材胶粘剂的生产。

President Hu rejected accusations that China was exploiting Zambian labour and resources."China is happy to have Zambia as a good friend, good partner and a good brother," he said, adding that the relationship between the two countries "represents a new type of strategic partnership" in Africa.

主席对"中国正在开采赞比亚的劳动力资源和矿产资源而自肥"进行了批驳，他说"中国很高兴能拥有赞比亚这样一个好朋友，一个好伙伴，一个好兄弟"他还说"我们二国之间的关系在非洲是一种新型战略伙伴关系"。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
