塔里木盆地轮南地区三叠系非均质薄砂岩储层预测
Prediction of heterogeneous,thin Triassic sandstone reservoirs in the Lunnan area,Tarim Basin
摘要
Abstract
The Triassic strata in the Lunnan area of the Tarim Basin represent a continental deltaic sedimentary system,with sedimenta-ry subfacies including deltaic plain,deltaic front,and prodelta.The rapid phase transition of reservoirs and the high-frequency sand-mudstone alternating deposition create thin,highly heterogeneous reservoirs,rendering high-precision reservoir prediction extremely chal-lenging.Under the guidance of sedimentary petrology and seismic sequence stratigraphy,this study conducted comprehensive seismic and geological research.Then,based on isochronous sequence interpretation,as well as seismic facies analytical results,this study estab-lished a lithofacies model.By constraining the pre-stack geostatistical inversion process,this study determined the spatial distribution of sand bodies.The practical application demonstrates that the proposed method enhances the vertical resolution of heterogeneous,thin res-ervoirs while significantly reducing lateral uncertainty.The predicted results align with actual drilling and production performance data and thus can provide valuable support for the efficient exploitation of hydrocarbon reservoirs.关键词
