    摘要:

    通过岩心、测井、录井、分析化验等资料,对南图尔盖盆地NN油田中侏罗统DOSHAN组沉积相进行研究,首次在南图尔盖盆地阿雷斯库姆坳陷侏罗系Doshan组(J2ds)中发现一套冲积扇入湖形成的扇三角洲相沉积体,进一步可识别出3个亚相和6个微相,其中水下分流河道和碎屑流微相最为发育。沉积演化规律:随着湖平面缓慢上升,东北及东南两大物源区逐渐向后退却,扇三角洲平原亚相面积逐渐减小,代之以扇三角洲前缘亚相为主。扇三角洲前缘碎屑流及水下分流河道延伸距离亦逐渐变短。扇三角洲前缘中的水下分流河道及河口砂坝砂体物性最好,是最有利的油气储集体,前扇三角洲暗色泥岩可作为重要的烃源岩和盖层。

    Abstract:

    Abstract: By systematic investigation on the sedimentary phase through core sample observations, sedimentary structures, sedimentary sequences, analytical chemical tests, well logging, well testing and study of the regional tectonic background, we first found a delta fan phase in the A Lei Si Ku Mu depression of the Tu Er Gai Basin in the Doshan Group of Jurassic System. We can identify three sub-phases including delta plain, delta front and prodelta as well six microfacies including clastic flow, submerged distributary channel, tributary bay, mouth bar, distal bar and prodelta mud. Among them, submerged distributary and clastic flow micofacies were well developed.It’s a series evolution of Sedimentary that with the lake level rise slowly, Southeast and northeast two major source areas gradually retreat, the fan delta plain subfacies area is gradually reduced,and replaced by the fan delta front subfacies. We know that the fan delta front of underwater distributary channel and mouth bar sand body is the most favorable oil and gas reservoirs, and also front fan delta dark mudstone can be used as an important hydrocarbon source rock and caprock.
