Abstract

Summary

The seismic response characteristics caused by fracture parameters are the basis for fracture prediction and further analysis of tight fractured reservoir, and must be given great weigh and analyzed precisely. We mainly analyzes the seismic responses of fractures on post-stack sections in different azumuths, and the fractures include fracture swarms and fractures zones with varied fracture densities. The size of fractured zones and fracture swarms we simulate here is from dozens of meters to hundreds of meters which is unusual in physical modeling. The conclusions are as follows: The fractured zones with obvious boundaries have strong response of string of beads on the blank geological background of the thick bed. Fracture swarms piercing through multi-layers have characteristics of scrambled reflection, energy attenuation, wider events, the distortion and fault of events, most of these characteristics are weak reflection, these characteristics are azimuthal.
