摘要
Geo-statistical inversion method based on stochastic modeling techniques has high vertical resolution prediction results,but its results show high randomness.Therefore,reliability evaluation of the inversion results is very important.By using geo-statistics method and through setting up different inversion parameters,the authors compared the inversion results and,in combination with geological regularity,selected the optimal inversion parameters to predict thin bedded alternation sand body of SII and SIII reservoir group in the development zone of northern Saertu oil field and analyzed the reliability of the inversion results qualitatively and quantitatively based on forward modeling.The results show that rational sampling rate of initial framework,reasonable well density of inversion,and variogram parameters in accord with geological conditions constitute necessary conditions for efficient inversion work and reliable inversion results.
