摘要:

为查明南海北部琼东南盆地生物成因和热成因天然气的资源潜力及其对天然气水合物成藏的贡献,根据琼东南海域天然气水合物调查区典型二维地震剖面,构建了该区的地质模型,并结合区域内岩性、地热和地球化学等参数对其进行了天然气水合物成藏的数值模拟。结果表明:琼东南盆地具备天然气水合物成藏的稳定域范围,稳定域厚度介于220~340m之间;生物气和热解气的资源潜力巨大,满足天然气水合物形成的气源条件;运移条件优越,有利于天然气水合物的聚集成藏。最后根据气体来源及其运移特征讨论了该区域天然气水合物成藏的地质模式。

Abstract:

To further investigate the resource potential of biogenic and thermogenic gases and its contribution to natural gas hydrate in the Qiongdongnan Basin,two typical sections in Qiongdongnan gas hydrate exploration area were chosen to build the geological model.In combination with physical,thermal and geochemical data,the process of gas hydrate accumulation was simulated by basin modeling computer programs.The results show that there is gas hydrate stability zone with thickness of 220-340m in the Qiongdongnan Basin; biogenic gas and thermogenic gas are abundant,which could be the resource for hydrate accumulation; migration pathways of gas in the basin are favorable for hydrate formation.Finally,the hydrate accumulation geological models in the basin were discussed according to gas resource and its migration characteristics.

Key words: Gas hydrate, Qiongdongnan Basin, Accumulation model, Biogenic gas, Thermogenic gas
