Ebola是纤丝病毒科家族伊波拉病毒种群的一个病毒组以及它们导致的伊波拉出血性高烧的常用术语。此病毒是以伊波拉河命名的,在那里爆发了首度伊波拉出血性高烧。这些病毒以细长的纤丝为标志,并且有类似于同样隶属于纤丝病毒科家族并且具备同样的疾病特征的绿猴病毒的形态。自从发现以来,伊波拉病毒已经导致多起死亡。

伊波拉病毒首次于1976年在扎伊尔和苏丹的伊波拉出血性高烧的爆发中露面。扎伊尔爆发的伊波拉种群具备人类致病菌的最高死亡率,大约为90%。随后在苏丹爆发的伊波拉种群具备约为50%死亡率。此病毒被认为是通过和一个感染了的动物饲养主接触传染给人类的。随后此病毒通过与被感染的人的血液和体液接触,以及受污染的医疗设备例如针头的接触而传染给其他人。这两种传染机制在临床和非临床情况下发生。因为其高死亡率,及死亡速度,发生了感染的遥远地区的潜在的广泛扩散几率被认为是很低的。

伊波拉被认为是动物生理学病毒,目前它正破坏着中非猩猩种群的数量。在2005年后期,三种狐蝠被认为是自然寄主,或此病毒的携带者。

伊波拉出血性高烧可能是致命的,并带有一系列的症状,包括高烧,呕吐,腹泻,大面积疼痛或抑郁,有时候是内外部的流血。死亡率极高,从50%到89%,取决于病毒类型。死亡原因通常是器官衰竭。

伊波拉可能是致命的,目前还没有公认的疫苗或治疗,它被定义为生物研究安全性4级物质,同时被疾病中心定义为生物恐怖主义物质。它可能在生物战争中被武器化。 伊波拉的作为生物战争物质的有效性来自于它的高死亡率和感染级别:一次典型的在小村落或医院里的爆发,会感染整个人口,接着从寄主体内脱出,在到达更广泛的社区前灭绝。值得注意的是,没有一种导致人类疾病的伊波拉病毒被认为是可以通过空气传播的---只有Reston(以其发现地弗吉尼亚州的城市Reston命名,在那里,此病毒起初被认为是绿猴病毒)被认为是可以通过空气传播的。

 

译文:Ebola


Ebola is the common term for a group of belonging to genus Ebolavirus, family , and for the disease that they cause, Ebola . The virus is named after the ,where the first recognized outbreak of Ebola hemorrhagic feveroccurred. The viruses are characterized by long filaments, and have ashape similar to that of the , also in the family Filoviridae, and possessing similar disease symptoms. Since its discovery, Ebolavirus has been responsible for a number of deaths.

Ebolavirus first came to light in 1976 in outbreaks of Ebola hemorrhagic fever in and . The strain of Ebola that broke out in Zaire has one of the highest of any human pathogenic virus, roughly 90%. The strain that broke out later in Sudan has a case fatality rate of around 50%. The virus is believed to be transmitted to humans via contact with an infected animal .The virus is then transmitted to other people that come into contactwith blood and bodily fluids of the infected person, and by humancontact with contaminated medical equipment such as needles. Both ofthese infectious mechanisms will occur in clinical ()and non-clinical situations. Due to the high fatality rate, therapidity of demise, and the often remote areas where infections occur,the potential for widespread outbreaks is considered low.

Ebola is believed to be a virus, as it is currently devastating the populations of in . As of late 2005, three species of have been identified as carrying the virus but not showing diseasesymptoms, and they are now believed to be the natural host species, orreservoir, of the virus.

Ebola hemorrhagic fever is potentially lethal and encompasses a range of symptoms including , , , generalized pain or malaise, and sometimes and . are extremely high, with the human case-fatality rate ranging from 50–89%, depending on viral subtype. The cause of death is usually due to or .

Ebola is potentially lethal, and, since no approved or treatment is available, it is classified as a agent, as well as a agent by the . It has the potential to be weaponized for use in .Its effectiveness as a biological-warfare agent is compromised by itsextreme deadliness and its level of contagion: A typical outbreakspreads through a small village or hospital, infects the entirepopulation, and then runs out of potential hosts, dying out beforereaching the wider community. It is also significant to note that noneof the strains of Ebola known to cause disease in humans has been foundto be airborne—only the strain known as Ebola Reston (after the city of where it was first identified in Green Monkeys) is believed to be airborne.

摘要 在溶解气驱气藏中,选择恰当的油管尺寸是主要扩大经济储量开采的途径。对具有较宽泄油边界的多产层气藏完井的井,油管尺寸的选择变得十分复杂。本文给出了一种利用节点分析和气体举升技术确定最优油管尺寸的方法。在分析了340口气井的基础数据后,并把这些数据用来确定这种方法的可用性和建立模型。这个模型给出了气藏废弃压力(Pab),渗透率厚度,油管尺寸和流动井口压力的关系。这个模型表明,在高渗透率厚度(Pab)完井时,油管尺寸对气藏废弃压力影响很小,实际现场数据证实了模型预测的结果。

  研究结果表明,7口井的油管尺寸从2 换成3 ,产能增加50MMCFD,实际结果与预测很相近,并且表明使用此方法很有精确性。

介绍 VICO有四个主要产气区,平均生产106BSCFD。这些区域包括超过300个唯一的拥有小于1md到大于1500md的气藏。在440口井中的大部分井采用双层完井,他们的区域是5000~14000英尺,sanga-sanga区块有三种系统压力,高(950Psi),中(375Psi),低(150Psi),具有代表性的,在高压力系统中有一新的完井,在衰竭之前,从中压力系统降到低压力系统。

  油管尺寸选择是完井设计中的重要因素,它会影响井动态和最终储量的开发率。我们希望在最大流速下生产而不影响储量的开发速度。增加油管尺寸通常会增加流速,可是问题是油管尺寸是如何影响储层的采收率的。在优化油管尺寸选择时要求有油管选择的导向。这个导向同样也被储油量控制和计划所要求的。

理论背景 选择油管尺寸最重要的因素是确定井何时加载和死井。确定影响加载的因素的研究已经有很多年了。卸载井的最小流速决定于油管的尺寸,流体区域和油管流动压力。两种
