塔里木盆地北部三叠系为一套辫状三角洲(夹扇三角洲)-湖泊沉积体系、南部为正常三角洲-湖泊沉积体系;而侏罗系为宽浅湖盆中的河流-滨钱湖沉积体系。塔里木盆地三叠-侏罗系储集体类型包括辫状三角洲砂岩体、扇三角洲砂岩体、三角洲砂岩体、河流砂岩体和滨浅湖砂岩体等。辫状三角洲砂岩体或扇三角洲砂岩体分布在北部陡坡,厚度向南增大;三角洲砂岩体分布在盆地南部,厚度向拗陷边缘减小;滨浅湖砂岩体和河流砂岩体则分布在环湖中心及盆地边缘。
The Triassic in the northern part of the Tarim Basin is a braided delta (fan-delta) - lacustrine sedimentary system with normal delta-lacustrine sedimentary system in the southern part of the Tarim Basin. The Jurassic system is a river-shore Qianhu sedimentary system in the broad-shallow lake basin. Triassic-Jurassic reservoir types in the Tarim Basin include braided delta sandstone bodies, fan deltaic sandstone bodies, deltaic sandstone bodies, river sand bodies and shore-shallow lake sandstone bodies. Braided deltaic sandstone bodies or fan deltaic sandstone bodies are distributed on the northern steep slope with an increasing thickness to the south. The deltaic sandstone bodies are distributed in the southern part of the basin and the thickness decreases toward the margin of the depression. The shallow sandstone bodies and river sandstone bodies distribute in the ring Lake center and basin edge.
