Abstract
The modified Contact Cement Theory (CCT) is applied to predict the acoustic velocities of heavy oil sand in this paper. The existence of contact thickness in the heavy oil sand reduces its moduli and acoustic velocities, which is ignored in the original CCT. To take into account this effect, the modified CCT is adopted in this paper and its approximation is obtained to simplify its application. Using this approximation, the acoustic velocities of the heavy oil sand in Xinjiang Oil Field are predicted. The results show that without considering the effects of contact thickness, the acoustic velocities will be largely overestimated. By using the modified CCT, the influence of contact thickness is considered and the accuracy for the acoustic velocities prediction of heavy oil sand improves greatly.
