摘要
Abstract
Since carbonate reservoir are pores,crack development and complicated structures to realize homogeneous sandstone reservoir characteristics with the acoustic responses is not applicable to this carbonate reservoir.We choose the different development degree carbonate rocks holes samples of Longwangmiao group,Sichuan basin to measure the same rock samples under different confining pressures and water saturations at vertical and horizontal wave velocity.On the basis of test data,we study vertical and horizontal wave velocity,and vertical and horizontal wave velocity ratio and acoustic attenuation characteristics changing with the water saturations under the condition of different confining pressures,and explained the internal mechanism of the change rule.The research of carbonate rocks acoustic wave propagation characteristics under different confining pressures and water saturations provides a theoretical basis for gas layer recognition and gas saturation and the porosity evaluation and prediction in carbonate reservoir by acoustic logging data,it is significance to the formation underground engineering stability study and reservoir evaluation.关键词
