摘要
为了分析天然气水合物形成与煤层的关系,通过野外地质钻探和研究成果分析,结合研究区DK12-13、DK8-19和DK4-24钻孔地质特征及天然气水合物的赋存特征对比研究,探讨了煤层对天然气水合物形成的气源作用、运移通道作用、储集层作用,得出三露天天然气水合物的形成在成因上与煤层关系密切。
In order to analyze the relationship between formation of natural gas hydrates and coal bed,through field geological drilling and results analysis,the functions of the gas source,migration pathway,reservoir stratum of coal bed on the formation of natural gas hydrates are discussed, combined with contrastive study of geological features and occurrence characteristics of natural gas hydrates in DK12- 13,DK8- 19 and DK4- 24 drilling in the study area. The results show that the formation of natural gas hydrates is genetically related to coal bed in Sanlutian.
