SEISMIC RESPONSES TO PORE-HOLE RESERVOIR BY PHYSICAL MODELING

CAO Jun, HE Zhen-hua, HUANG De-ji, LI Qiongon, Chengdu University of Technology, China)  
According to physical modeling similarity theory, different materials and pore-hole density (physical) models were made. Seismic responses to pore-hole physical models made of different materials and pore-hole density and under different pressure and temperature conditions were measured using MTS(a rock Mechanics Test System). The authors analyse the influences of pore-hole density on seismic waves (attribute) parameters. Pore-hole density, pressure, temperature, material and fluid can apparently (influence) on seismic waves attributes such as velocity, amplitude, attenuation etc. But, seismic wave (dynamic) characteristics are more evident than its kinematical characteristics. Therefore, seismic amplitude and attenuation may be more effective than seismic velocity on the detection of the pore-hole characteristics of reservoir.
