摘要: 将化工中的可动吸附模型[1]应用于气藏工程中,建立考虑吸附的原始地质储量的理论模型。首先对化工中分子筛上的单组分吸附实验数据进行了拟合,在此基础上对双组份吸附的实验数据进行了预测,通过和实验数据的对比分析,验证了本模型的可靠性;然后采用Clark[2]在砂岩及砂岩-粘土多孔介质中测得的单组分吸附实验数据和单组分吸附延伸扩展方法,获得了其它单组分的吸附扩展实验数据和基础吸附参数,应用此参数分别对实际的天然气和凝析气在不同多孔介质中的吸附进行了计算。通过计算说明不同介质及不同体系组成的气藏在原始条件下考虑
吸附对常规地质储量产生的影响程度。

Abstract: This paper raises a theoretical model, which considers the effect of adsorption on reserves in place. The Movable Adsorption Model in chemical industry is adopted to calculate the adsorption of gas in gas reservoirs. At first, we simulate the single component adsorptive experiment data so as to gain some basic parameters and apply the experimental data of a two components system to exam the adsorptive model. Then we gain the fundamental parameters on the basis of simulating the real single component adsorptive experiment data or the spread theory of adsorption of single component in more actual porous media by Clark, a actual multi Component natural gas
system and a gas condense system are calculated respectively as examples. At the end, we give the tendency and extent of the effection reserves in place under different formation conditions such as systems, porous media and others.

Key words: Absorption, Gas reservoir, Reserve
