石油工程专业英语-油藏管理技术重点句子reservoirmanagement内容摘要：

能够顶起液柱而使油井自喷。 如果不够大的话，就必须利用人工举升的方法。 17. Natural gas dissolved in oil will e out of solution and form bubbles, which expand as the fluid pressure is reduced. 溶解在原油中的天然气将从溶液中跑出来并形成气泡，这些气泡随流体压力降低而增大。 18. Secondary recovery in solutiongas drive reservoir involves the injection of gas or water to replace produce volumes and thus maintain reservoir pressure. 在溶解气驱油藏中，二次采油涉及到了注水或注气，目的是补充减少的体积并维持油藏压力。 19. The larger the gas cap volume relative to the oil volume, the lower will be the pressure loss in the gas cap for a given amount of oil production. 当产出一定原油时，相对于原油体积而言，气顶的 体积越大，气顶的压力损失越小。 20. Gas or water injection can be utilized to maintain pressure in a gascap drive reservoir, just as it is practiced in a sotutiongas drive reservoir. 随着注水或注气在溶解气驱油藏中的应用，为了维持油藏压力，它也慢慢的运用在气顶驱油藏中。 21. Often it is difficult to determine exactly how much each mechanism contributes to the overall recovery. 通常很难准确确定每种机理对采收率所起的作用。 22. As a relationship between pressure drop and volume changes, the material balance equation is very valuable because it enables one to make an estimate of the original volume of hydrocarbons basedonthe pressureproduction performance. 随着压力降与体积的关系，物质平衡方程式是非常重要的。 基于压力 产量曲线，人们能预测碳水化合物的地质储量。 23. If the reservoir hydrocarbon position is such that the accumulation exists as a gas at reservoir conditions, production of such a gas reservoir is usually a matter of simple gas expansion, sometimes assisted by water influx. Recovery is generally very good, particularly if the bottomhole flowing pressure can be reduced to a minimum, by lowering the backpressure at the wellhead with pressors. In such cases, recovery can be as high as 85% to 90%. 如果储集层的碳氢化合物是包含气体存在，在开发含气油藏时气体膨胀，有时还有水的参与。 采收率在井底流压被降低很小时、在井口回压被压缩机控制的很低时有很大值，在一些情况下，采收率可以高达 85%— 90%。 24. The methods differ in the nature of the fluids used and the physical changes they bring about in the reservoir, but water usually plays a part inhelping to displace the oil. 在以存在的和储层中发生变化的自然流体的研究方法不同，但是水在驱替油时扮演重要的角色。 25. The mobility of any fluid in a porous medium such as reservoir rock is directly proportioned to its velocity or flow and is equal to the effective permeability to that fluid divided by the fluid viscosity. 在例如储层岩石的多孔介质中任何流体的流变形都和它的速率、流态有关，并且按照流体的粘度不同而划分。 26. The mobility ratio is defined as the mobility of the displacing phase in the portion of the reservoir contacted by the injected fluid, divided by the mobility of the displaced case of water displacing oil (waterflooding)。 流度比是有注入流体的储层中取代相流体流动能力所占的比例，在注入水的情况如下面公式。 2。
