【簡答題】翻譯：For an oil reservoir, as pressure decreases with production, a value is reached at which a portion of the liquid vaporizes to produce a gas phase that then exists in equilibrium with liquid.

答案：

對于一個油藏，當(dāng)油藏壓力隨生產(chǎn)下降時，將出現(xiàn)一個部分液體蒸發(fā)形成氣相，并以此處于氣液平衡狀態(tài)的壓力值。

【簡答題】翻譯：The production rate of free gas at reservoir conditions is therefore the product of the difference (R - Rs) times the surface production rate of oil times the gas formation volume factorBg.

答案：

油藏自由氣產(chǎn)量等于(R-Rs)以油的地面產(chǎn)量和Bg之積。

【簡答題】翻譯：Their solubility is due to the elevated pressure and temperature existing underground.

答案：

溶解度取決于當(dāng)前層的溫度和壓力。
