摘要

页岩作为一种常见的二氧化碳储层，受到广泛的研究。其中一个主题是页岩中超临界二氧化碳注入的突破现象，其性质仍有待充分了解。本文研究了一种可能用于解释突破行为的两相流模型。模型考虑了毛细效应和地质力学，确定了影响模型的参数。

Explaining breakthrough behaviour in shale rock: influence of capillary effects and geomechanics

Shale rock, being a common caprock for carbon dioxide reservoirs, is subject to extensive research. One of the topics is breakthrough phenomena during injection of supercritical carbon dioxide in shale, the nature of which is still to be fully understood. In the present paper, a two-phase flow model, which may possibly be used to explain the breakthrough behaviour is examined. Capillary effects and geomechanics are included in the model, and influential model parameters are determined.
