中文摘要：
在总结前人对泥岩盖层评价指标的基础上，通过对中国南方海相碳酸盐岩地区泥岩样品的常规物性参数的分析，认为用常规参数很难对盖层的封盖性能作出有效的判识。在此基础上，通过分析比表面积和突破压力与盖层封盖性能的关系，提出了以此表耐积与突破压力2个参数共同建立盖层评价模板。该指标的建立可以对盖层的封盖性能做出较为客观的评价。
英文摘要：
Based on summaries of previous analyses of evaluation standard of mudstone caprocks, it was analyzed in this paper the conventional physical parameters of mudstone samples from marine carbonate area in South China. It was concluded that the conventional physical parameters could not accurately evaluate the seal capability of mudstone caproeks. A new template to evaluate seal capability combining specific surface area and breakthrough pressure was proposed, providing relatively objective evaluation for seal capability of caprocks.
