国家“973”项目“羌塘盆地演化与油气资源远景”课题对羌塘盆地进行了深入研究,在比隆错—昂达尔错发现了古油藏带,证实羌塘盆地存在大规模油气聚集和成藏过程。国土资源部“青藏高原重点沉积盆地油气资源潜力分析”项目等,对西藏主要海相盆地油气地质条件作了进一步研究,已初步证实西藏羌塘盆地具有较好的油气资源潜力。本文以2011羌塘盆地毕洛错地区天然气水合物1:5万区块地质调查为依托,以实测盆地露头剖面观测为
The national “973 ” project “Qiangtang Basin evolution and the prospect of oil and gas resources ” conducted an in-depth study of the Qiangtang basin, and discovered the paleo-oil reservoir zone in the Billucan-Ondal fault, confirming the existence of large Scale hydrocarbon accumulation and accumulation process. Ministry of Land and Resources “Project of Potential Analysis of Hydrocarbon Resources in the Key Sedimentary Basins of the Qinghai-Tibet Plateau ” and so on. The geological conditions of oil and gas in the major marine basins in Tibet have been further studied. It has been tentatively confirmed that the Qiangtang Basin in Tibet has good potential for oil and gas resources. Based on the geological survey of 1: 50,000 zone of natural gas hydrate in the Bioluo area in the Qiangtang Basin in 2011, the present study measured the outcrop profile of the basin as
