問答題

【簡答題】翻譯：The fluids of a petroleum reservoir are generally gas, oil, and water in varying proportions. Each phase can differ widely in composition and properties. Gas and oil, either as separate fluids or in mixtures, change their state or phase as reservoir pressure changes.

答案：油層中的流體是天然氣、石油和水各占不同的比例。在不同的狀態(tài)下它們的性質(zhì)和組成是不同的。氣和油既可以是分開的流體，也可以...

【簡答題】翻譯：Since the volume factors and the solution gas-oil ratio are determined from laboratory measurements on samples of reservoir fluid at reservoir temperature and various pressures, these parameters are effective substitutes for detailed phase equilibrium data in most production calculations. However, these parameters are unknown at the time that exploration well tests are run, and hence they are estimated from correlation charts.

答案：因為體積系數(shù)和溶解油氣比的測定是實驗室采集地層溫度下和不同壓力下的地層流體樣品來測定的，因此這些參數(shù)在很多產(chǎn)量計算中可以...

【簡答題】翻譯：A porous medium has a permeability of one darcy when a single phase fluid of one centipoise viscosity that completely fills the voids of the medium, will flow through it under conditions of viscous flow at a rate of one cubic centimeter per second per square centimeter cross sectional area under a pressure or equivalent hydraulic gradient of one atmosphere per centimeter.

答案：當粘度為1厘泊的單相流體被完全充滿-多孔介質(zhì)的孔隙時，在粘滯性流體以1立方厘米每秒或每平方厘米的相當于每厘米一個大氣壓的...
