摘要
天然气储量与石油当量的传统换算关系是将1000m3天然气换算成1t石油当量,由此计算的石油当量值误差相当大。根据天然气组分性质采用密度换算法和气液体积系数换算法进行油气当量换算,既避免了体积与质量两种不同单位之间直接换算导致的误差,又避免了气态与液态两种不同状态之间直接换算引起的误差,使油气当量换算结果准确可靠。
The traditional conversion relationship between gas reserves and oil equivalent is that 1000m3 gas is equivalent to 1t oil. There is a very great error in the calculated result of oil equivalent with this traditionalmethod.According to the properties of the component of the natural gas,the density conversion method andvolumetric coefficient conversion method of oil and gas have been used in this paper.With these two methods,not only the error which is caused by direct conversion between two different units of mass and volume canbe avoided, but also the error which is caused by direct conversion between two different states of gas andliquid can be avoided.The principle conversion of oil and gas equivalent is more reasonable and the calculation results are more reliable with these two methods.
