摘要:
根据质量平衡原理和Avogadro(阿伏伽德罗)定律,经理论推导得到了利用称重吸附仪测试的数据计算页岩气等温累积吸附量的方法。理论分析和实例应用表明,等温累积吸附量与压力之间是一条带峰值的曲线,峰值为等温饱和累积吸附量,峰位为累积饱和吸附压力,峰值之前的曲线符合陈氏的等温累积吸附量方程。本文还提出了确定饱和吸附压力和等温累积饱和吸附量的交会法,并通过应用实例验证了本文方法的正确有效性。
Abstract:
According to the principle of mass balance and Avogadro's law, the method of calculating the isothermal cumulative adsorption capacity of shale gas was theoretically derived by using the test data of the weighing adsorption instrument. Theoretical analysis and case applications show that the relationship between isothermal cumulative adsorption capacity and pressure is a curve with peak value; the peak value is the isothermal saturated cumulative adsorption capacity; the peak position is the cumulative saturated adsorption pressure, and the curve prior to the peak is consistent with the Chen's isothermal cumulative adsorption capacity equation. This paper also proposes an intersection method for determining the saturated adsorption pressure and the isothermal cumulative saturated adsorption capacity, and the correctness and effectiveness of the proposed method were validated by the field application cases.
