Characterization of the Complex Glutenite Reservoir in Yan22 Block of Yanjia Oilfield
摘要
Abstract
The optimal fusion of multi-probability function and lithofacies modeling is used to identify the distribu-tion of complex glutenite reservoir in the upper member of Sha4 in Yan22 block and discuss its lateral and longitudi-nal distributions. Research indicates that 3 types of lithofacies can be identified through the glutenite reservoir log-ging data,including the high-quality glutenite reservoir,coarse conglomerate reservoir with medium-quality and mudstone as non-reservoir. There is a positive rhythm in the longitudinal direction of Sha4 upper member,where relatively low-quality reservoirs develop in the I,II and IV sandgroups.The Sandgroup III with best reservoir quali-ty includes 4 large-scale glutenite reservoirs,which are featured by"large integral thickness,small thickness of single layer,short lateral scale". This research could provide certain guidance to the characterization of glutenite reservoirs in Dongying Sag and other similar glutenite reservoirs.关键词
