研究表明羌塘盆地在油气资源的许多方面可与中东特提斯油气集聚区相类比,因而成为中国油气资源战略选区的首选目标之一。羌塘盆地的构造部位相当于中东特提斯构造域的北亚带和中亚带,羌塘盆地晚古生代是一个被动大陆边缘盆地,中生代是一个复合式前陆盆地,新生代叠置成为第三纪走滑断陷盆地;羌塘盆地内发育有极为良好的生储盖组合,生油岩主要为三叠系—侏罗系的泥岩、灰岩和油页岩,烃源层处于成熟 过成熟阶段,生油高峰期为晚侏罗世—古近纪,局部发现厚达70余米的油页岩,初步估计油气资源总量为50亿吨左右;盆地内发育有孔渗极佳的碎屑岩、白云岩以及生物礁(滩)岩等储集层,其次生孔隙的形成期与烃岩的生油高峰期一致;盆地内发育泥岩、泥灰岩和石膏等多套盖层,累计厚度可达3000多米,尤其是发育中东油田最好的石膏储层,累计厚度达177m,其中,仅中侏罗统布曲组最大单层厚度达93m;盆地内发育数十个形态好、保存完整的大中型背斜和穹隆圈闭构造,它们均定型于侏罗纪末期,为油气运移和圈闭创造了良好的条件;盆地内共发现油气显示190余处,其中包括5处液态油苗,数处见厚达数厘米的板状沥青,并发现面积约10km2的古油气藏一个;藏北高原的抬升属整体的均一抬升,剥蚀强度不大,岩浆活动广泛,但除盆地东南部外,规模小,对油? Research shows that the Qiangtang Basin is comparable to the Tethys area in the Middle East in many aspects of oil and gas resources and therefore has become one of the preferred targets for the strategic selection of oil and gas resources in China. The tectonic parts of the Qiangtang basin correspond to the northern and middle-subtropical belts of the Tethys tectonics in the Middle East. The Late Paleozoic in the Qiangtang basin is a passive continental margin basin, and the Mesozoic is a composite foreland basin. The Cenozoic overburden became the Triassic strike-slip rift basins; well-developed reservoir-cap assemblages are developed in the Qiangtang basin. The source rocks are mainly Triassic-Jurassic mudstone, limestone and oil shale. The source rocks are mature At the mature stage, the peak of oil generation is late Jurassic-Paleogene, with oil shale thickly found up to 70 meters thick. The preliminary estimation of total oil and gas resources is about 5 billion tons; Clastic rocks, dolomites and reef (beach) rocks and other reservoirs. The formation of secondary pores coincides with the peak period of oil generation of hydrocarbon rocks. Many sets of cap rocks, such as mudstone, marl and gypsum, The accumulated thickness can reach more than 3000 meters, especially the best gypsum reservoir in Middle East Oilfield. The accumulated thickness is up to 177m. Among them, only the largest monolayer in the Middle Jurassic Buqu Formation is 93m thick. Dozens of well- Large, medium-sized anticlinal and dome traps have been preserved, all of which are stereotyped in the Jurassic In the end of Jiage, favorable conditions have been created for the migration and trapping of oil and gas. More than 190 oil and gas discoveries have been found in the basin, including 5 liquid oil seedlings and a few centimeters of thick plate bitumen at several sites. A 10 km2 paleo-oil and gas reservoir. The uplifts in the northern Tibet plateau are generally uplifted uniformly with little denudation strength and extensive magmatic activity. However, except for the southeastern part of the basin,
