Abstract

Abstract:

The tight sandstone reservoirs in Xujiahe Formation in Sichuan are rich in oil and gas, but highly heterogeneous. The tight sandstone fractured reservoirs of Xujiahe Formation in Western Sichuan Depression are characterized by heterogeneity. Combining with the actual situation and based on rock physics analysis, the relationship between reservoir characteristic parameters and anisotropy parameters is deduced, and the anisotropic elastic impedance inversion workflow of tight sandstone reservoirs is carried out. Based on the proposed fracture parameter inversion method, the model and the actual work field data are tested, respectively. The results show that the proposed approach has great robustness, the inversion results are in good agreement with the well-log, and the estimated anisotropy parameters can accurately show the location of fractured reservoirs and achieve effective description of the fracture characteristics of tight sandstone reservoirs.

Key words: tight sandstone, reservoir fracture, anisotropy, elastic impedance inversion
