| 摘 要： | 位于青藏高原腹地的羌塘盆地是经历了多期构造改造的改造型盆地。通过对盆地地层暴露程度、变质作用．火山-岩浆活动和构造变形强度综合研究，将羌塘盆地划分为弱构造改造区、中等强改造区和强改造区3种改造类型。在此基础上，结合生、储、盖层特征、保存条件、构造条件和地表油气显示，采用多重信息叠合法将羌塘盆地划分为油气有利区、较有利区、较差区和不利区，其中吐坡错-确旦错-半岛湖地区、白滩湖-波涛湖地区、比洛错东-土门地区和长梁山-黑尖山地区为盆地油气有利远景区。 |

| Abstract: | The Qiangtang Basin in the hinterland of the Qinghai-Xizang Plateau is interpreted as a reworked basin which has undergone multiple phases of tectonic reworking.The integration of outcrops,metamorphism,volcanism and magmatism,and structural deformation of the strata in the basin permits the division of the basin into three provinces: slightly reworked area;moderately reworked area and highly reworked area.In addition,the combination of source rocks,reservoir rocks,cap rocks,preservation,structural conditions and oil and gas shows in intergration with multiple information results in the delineation of the basin as the favourable area,raletively favourable area,poor area and unfavourable area for hydrocarbon accumulation.The Tupoco-(Quedanco)-Bandaohu,Baitanhu-Botaohu,East Biluoco-Tumain and Changliangshan-Heijianshan zones are(considered) as favourable areas for hydrocarbon accumulation in the Qiangtang Basin. |
| Keywords: | tectonic reworking oil and gas potential Qiangtang Basin Qinghai-Xizang Plateau |
