塔里木盆地三叠－侏罗系储层主要是各类三角洲的分流河道、水下分流河道、河口坝、三角洲前缘席状砂及河道砂、滨浅湖砂坝等沉积环境的砂体。地震地质层位标定及合成记录分析的结果表明：三角洲前缘沉积表现为强振幅连续平行相（Ａ相）反射；辫状三角洲（夹扇二角洲）前缘、滨浅湖、曲流河沉积表现为弱振幅不连续发散相（Ｂ相）反射。在此基础上分析全区地震反射特征，‘可预测沉积环境和有利储层的展布：在塔里木盆地东部湖盆的北部（ＹＭ１井至ＬＮ１井附近地区），三叠系辫状三角洲前缘沉积较厚，该区以东的Ｂ地震相等时差的高值区代表了滨浅湖砂坝沉积厚度较大的区块，是良好储层的分布区；在塔里木盆地南部，分布有多块等时差高值区，表明这些区块的砂体沉积厚度较大，是勘探的有利区域。
The Triassic-Jurassic reservoirs in the Tarim Basin are mainly sand bodies of sedimentary environment such as distributary channel, underwater distributary channel, estuarine dam, delta front sand and channel sand, and shore-shallow lacustrine sand bar in all kinds of delta. Seismic stratigraphic calibration and synthetic records show that the deposition of the delta front is characterized by a strong amplitude of continuous parallel phase (A-phase) reflection, the front of the braided delta (fan-delta), shallow foreshore and meandering river Sediment showed weak amplitude discontinuous divergent phase (B phase) reflection. On this basis, the seismic reflection characteristics of the whole area are analyzed, and the prediction of sedimentary environment and distribution of favorable reservoirs can be predicted. In the northern part of the eastern lake basin from YM1 to the vicinity of LN1 well, the Triassic braided delta front Thick deposits, and the high value area of the equal time difference of the B earthquake to the east of the area represents a block with a relatively large sedimentary thickness of the shore-shallow lacustrine sand bar, which is a good reservoir distribution area. In the southern part of the Tarim Basin, there are multiple The high value of time zone indicates that the sand bodies of these blocks are relatively thick, which is a favorable area for exploration.
