| 摘 要： | 利用塔北西部英买46井区取心井资料, 分别从粒度参数特征、概率累计曲线和离散图3个方面对巴西改组2套储层碎屑颗粒的粒度大小、分选性、水动力强弱等方面进行了特征分析对比和沉积环境推断。结果表明: 英买46井区块状砂岩碎屑颗粒粒度较粗, 分选为中等—较好, 具有远物源、较强水动力特征；薄砂层碎屑颗粒粒度粗—细粒,分选为差一较好, 水动力由强变弱；块状砂岩和薄砂层均以跳跃组分为主。通过与相关沉积环境的粒度特征及其反映的沉积物特点比较认为, 块状砂岩为辫状河三角洲水下分流河道沉积环境, 而薄砂层为辫状河三角洲前缘席状砂沉积环境。

| Abstract: | Using the data of the cores from the well Ym-46 area in the western part of Tabei (North Tarim Basin), the features of particle size, sorting, and hydrodynamic intensity, and so on were comparatively analyzed, and their sedimentary environment was deduced, for the clastic particles of two sets of reservoirs in the Baxigai Formation, respectively from the three aspects of the particle size parameter, the probability cumulative curves and the discrete figures. The results show that the particle size of the clastic particles of the block sandstone in the well Ym-46 area is coarse, sorted by medium-good, with far provenance and strong hydrodynamic characteristics. The particle size of the detrital particles of the thin sandstone layers is coarse-to-fine, sorted by poor-good, and the hydrodynamic force varied from strong to weak; massive sandstone and thin sandstone layers are mainly jumping components. Based on the comparison of the particle size characteristics of the related sedimentary environment and the characteristics of sediments reflected by the sedimentary environment, it is considered that the massive sandstone is underwater distributary channel sedimentary environment of a braided river delta, and the thin sand layers are sheet-sand sedimentary environment of braided river delta front. |
