摘要
天然气水合物作为一种新型的非常规能源具有较大的资源潜力。天然气水合物储层的有效绝对渗透率常被选为天然气水合物降压开采效果评价的关键指标,指标大小需要在现场进行测试加以确定。首先对国内外典型地区天然气水合物储层有效绝对渗透率的现场测试实例进行梳理,然后介绍了地层测试和核磁共振测井等现场测试方法,最后总结了目前水合物储层有效渗透率现场测试仍存在的主要问题并给出未来的研究建议,期望为天然气水合物储层现场测试技术的发展提供参考。
Natural gas hydrates have been widely treated as a potential energy.The effective absolute permeabil-ity of gas hydrate reservoirs is a crucial parameter reflecting the productivity,and it needs to be tested in the field.Advances in field testing of the effective absolute permeability of gas hydrate reservoirs in the world were re-viewed.In addition,field-testing methods including wireline formation test and nuclear magnetic resonance log-ging were introduced,and challenges in on-site testing were addressed.Finally,suggestions were given to devel-op new field testing methods for future studies.
