Application of a model-driven simultaneous prestack inversion of rock physical properties in ultra-deep Ordovician carbonate reservoirs in the Shunbei area

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