| 摘 要： | 为了获得无测井或岩心资料地区天然气水合物赋存海域未固结成岩地层的体积密度,对ODP164、ODP204、IODP311航次实际钻探资料进行了分析,统计了体积密度、孔隙度、颗粒密度的分布情况及其相互关系.分析结果表明,水合物赋存的未固结成岩地层孔隙度很高,一般大于40％,在此范围内体积密度主要受到孔隙度制约,而对骨架颗粒...

| Abstract: | The bulk density of unconsolidated bottom sediments is critical to gas hydrate resource assessment.The study of this paper is to find a way to estimate the bulk density of unconsolidated sea-bottom sediments bearing gas hydrate,when there is no well logging or core data available.Core dada including bulk density,porosity and grain density from ODP164,ODP204 and IODP311 were used in this study.And the distribution of these physical properties and relationship among them were analyzed.Results demonstrate that... |
