Abstract:

Ordovician carbonate dissolved cave reservoirs are widely developed in the district 6-7of Tahe Oilfield. The P-wave impedance is low whether or not there are fluids within cave reservoir, so P-impedance acquired frompost-stack inversion is not enough to identify the filled materials effectively. Pre-stack simultaneous inversion can be used to obtain S-wave information except P-wave information outside, and the combination of P-wave and S-wave information is in favor of distinguishing fluid. Pre-stack simultaneous inversion is applied in the district 6-7 of Tahe Oilfield. Multiple elastic parameters are acquired, including P-wave impedance, S-wave impedance and v p /v s . Based on rock physic analysis, cross-plots of P-wave impedance and vp/vs were used to distinguish oil-bearing reservoir and predict the fluid distribution. The fit rate between prediction results and actual drilling data is 72.7%, which indicates the pre-stack simultaneousinversionispractical andreliable.
