摘要: 资源量巨大的天然气水合物越来越引起人们的重视。针对目前海洋天然气水合物储层的测井评价问题,介绍了海洋天然气水合物的晶格结构、物理性质、分布形式和形成条件,结合天然气水合物的物理性质和储层特征,分析了海洋天然气水合物的常规测井响应特征。根据大量文献调研,得出目前利用测井方法求取天然气水合物储层的孔隙度和饱和度等参数的主要方法,对南海神狐海域含天然气水合物储层的实例站位进行泥质含量、天然气水合物饱和度评价。提出实验室合成人工岩芯研究天然气水合物时,需考虑泥质的存在。通过总结海洋天然气水合物测井评价研究进展的调研成果,为今后大规模海洋天然气水合物的储量预测及勘探开发提供重要依据,对天然气水合物资源的有效开采具有重要现实意义。

Abstract: More and more attention has been paid to natural gas hydrates with huge resources. Aiming to slove the present problem of logging evaluation of marine gas hydrate reservoirs, this paper introduces the lattice structures, physical properties, distribution form and formation conditions. According to the physical properties and reservoir characteristics of natural gas hydrates, the logging response characteristics of natural gas hydrates are analyzed. Based on the literatures investigation, the main methods of calculating the porosity and saturation of natural gas hydrate reservoir by logging method are obtained, the shale content and saturation of the natural gas hydrate reservoir in Shenhu of South China Sea are evaluated. It is suggested that the existence of shale should be considered in the study of natural gas hydrates by synthetic artificial core in laboratory. By summarizing the research results of well logging evaluation of marine gas hydrate, this paper provides an important basis for future large-scale prediction of marine gas hydrate reserves and exploration and development, and has important practical significance for effective exploitation of natural gas hydrate resources.

Key words: natural gas hydrate, well logging response, literature review, porosity, saturation
