凝析气藏工业气流量计算方法

国土资源部颁发的《DZ/T 0217-2005 石油天然气储量计算规范》给出了我国东部地区气藏不同埋藏深度下估算的工业气流标准,但该标准没有考虑气藏储渗条件的影响,也没有明显体现凝析油成分对工业气流的影响,不适合凝析气藏的对照使用。根据投入产出平衡原理,提出了凝析气藏工业气流计算模型,以我国西部凝析气藏为例,根据目前各项参数测算了相应的工业气流,绘制了工业气流图版。提出的方法也适用于含硫化氢等其他复杂成分气藏工业气流的计算。

Estimation Method for Industrial Gas Flow Rate of Condensate Gas Reservoir

The Regulation of Petroleum Reserves Estimation (DZ/T 0217-2005) published by the Ministry of Land and Resources, PRC,gives the estimation value of the industrial flow rate of exploration wells with different depths in eastern China without explicitly considering the contents of condensate oil and different reservoirs permeability. This regulation is not suitable for condensate gas reservoirs as a guide. Based on the principle of balance between input and output, a estimation model for industrial gas flow rate of condensate gas reservoir is proposed. Taking condensate gas reservoirs in western China as examples, the related industrial gas flow rates are estimated by using available parameters, and the corresponding charts are plotted. This method could also be suitable for complex gas reservoirs with other components such as H 2 S, etc.
