Article summary:

1. Gas migration in clay-based porous media is a complex process that involves dilatancy controlled gas flow, gas induced fracturing, and the development of gas preferential pathways.

2. Existing numerical models for simulating gas migration in claystone have limitations, such as not accounting for the saturated/unsaturated transition or assuming a single porosity model.

3. A coupled hydro-mechanical (HM) model based on double porosity poroelasticity is proposed in this paper to better simulate gas migration in argillaceous rocks. The model accounts for the HM behavior of both the matrix and fractures and is validated against laboratory experiments.

Article analysis:


1. 偏袒:文章只介绍了一种数学模型,并未探讨其他可能的模型或方法。这可能导致作者忽略了其他可能的解释和结果。

2. 片面报道:文章只关注了气体迁移对粘土岩的影响,但并未考虑其他因素对储存核废料的影响,例如地质构造、水文地质条件等。

3. 缺失考虑点:文章没有考虑气体迁移对环境和人类健康的潜在风险。如果气体泄漏到大气中,可能会对生态系统和人类健康造成危害。

4. 未探索反驳:文章没有探讨任何反驳或争议观点。这可能导致读者无法全面理解该领域的争议和不确定性。

5. 宣传内容:文章强调了核废料储存的必要性和安全性,但并未提及任何潜在问题或挑战。这可能会误导读者认为核废料储存是完全安全和可行的。
