摘要

吸附是页岩气的主要赋存形式之一,页岩吸附气量的测试及评价对页岩气藏储量评估和生产开发具有重要意义。本文基于体积法测试气体吸附量的基本原理,推导了页岩气超临界吸附实验数据校正方法,通过对比校正前后吸附量偏差,深入分析了页岩气超临界等温吸附曲线特征。
        Adsorption is one of the major occurrence modes for shale gas.Testing and evaluations of absorptive shale gas amount are crucial for reserve estimation and development of shale gas.The correction methods for shale gas supercritical adsorption is derived in this paper on the basis of volumetric method for testing adsorptive volumes.The characteristics of isothermal adsorption curves for supercritical shale gas is analyzed as well by comparing the deviation of adsorption quantity before and after correction.
