Abstract

Reservoirs are multiphase medium composed by the matrixs of solid, pore and the fluid in the pore. The properties of the pore should not be overlooked in oil and gas exploration. In orderto analyze the influence of pore shape on AVO response, two sets of sand shale model are selected to classify the pores by the pore shape. The equivalent modulus of rock is obtained by using Kuster- Toksoz formula, and then Biot- Gassmann equation is applied for fluid substitution to obtain the equivalent modulus of saturated rock. Finally the reflection coefficient obtained by Aki- Richards formula is used to carry out the AVO forward modeling. The result shows that the pore shape has significant effects on AVO response, and the influence onAVOresponse of different types of fluid-saturated rocks is similar.

Key words： carbonate rock; seismic reservoir; reservoir prediction technique
