“…As shown in Figure 1, the Shuntoguele Low Uplift is connected to the Tabei Uplift in the north, the Tazhong Uplift in the south, the Manjiaer Depression in the east, and the Awati Depression in the west, and it extends to the Shunnan Slope of the Guchengxu Uplift in the southeast (Liu et al, 2020;Lu et al, 2020;Li, 2022;Li et al, 2022). The study area comprises the dotted white box of Figure 1, covering 405 km 2 , and is magnified in the lower right inset.…”

Synchronous prestack inversion technology has been widely used to predict the fluid and lithological properties of reservoirs. Its prediction accuracy depends on the seismic data quality. Ultra-deep carbonate reservoirs in the Shunbei area of the Tarim Basin were used as research objects. Based on the shear wave (S-wave) prediction method, petrophysical logging analysis was carried out to select the physical property-sensitive elastic parameters. A physical property indicator with porosity as the target curve was constructed to quantitatively characterize the differences in physical properties in this area. The signal-to-noise ratio (SNR) and resolution of the dataset were improved by preprocessing the seismic and logging data. P- and S-wave impedances and densities obtained from prestack synchronous inversion, which integrate the physical property indicator model. Spatial distribution and transverse variation of the physical parameters of the Ordovician carbonate reservoirs are described. The planar distribution of reservoirs can be effectively predicted.
