摘要
通过研究战略选区项目基础地质与油气地质成果及已有资料,对西藏地区的石油、天然气资源的可能分布规律和勘探开发前景进行分析,认为西藏地区石油远景资源量121.26亿t,石油地质资源量69.61亿t,石油可采资源量14.00亿t。该项目通过技术攻关,总结出一套适合青藏高原二维地震勘探方法,建立了青藏高原地层物性柱,并分析了盆地主要物性界面,识别出三个明显的地质界面,确定了盆地结构和主要构造层的分布。研究表明,羌塘盆地具有形成大型油气田的资源潜力,羌塘以外海相盆地也具有一定油气勘探前景,伦坡拉含油气盆地群和可可西里含油气盆地群具有油气勘探前景。
Through basic geological data and some study about hydrocarbon resources in the project of strategic research,the oil gas resources and its distribution in Tibet are analyzed,and it is put forward that the prospective reserve of oil is about 121.26×108t,geologic reserve of oil is about 69.61×108t,recoverable reserve of oil is about 14.00×108t.Some methods of 2D seismic exploration are set especially for Qinghai-Tibet Plateau.Physical column of stratigraphic is set and analyzed.Three obvious geological interfaces are identified and some important structural layers are outlined.Through geological investigation,gravity-magnetic measuring and some other methods,it is thought that Qiangtang basin has good potentiality of giant oilgas field,and some other marine basins also have good exploration expectation,besides,Lunpola oil-bearing basin group and Hoh Xil oil-bearing basin group have as well.
