摘要
Abstract
Gas reservoirs of the Middle Permian Maokou Formation,Longnvsi-Hechuan area,Sichuan Basin,have achieved signifi-cant exploration discoveries,making them the best domain for the future breakthrough across trillions of cubic meters.There majorly developed dolomite reservoirs of intra-platform shoal facies in this formation,which extend along the edge of paleo-uplift with large-scale resources and great exploration prospects.However,Maokou reservoirs exhibit complex spatial distribution and poor physi-cal properties due to deep burial depth and various karstification,resulting in difficult fine interpretation of interlayers,ambiguous seismic-response characteristics,and challenges in reservoir prediction.For purpose of reservoir prediction and description on key parameters to support the exploration and development in this area,both ancient landform and favorable facies of the Maokou Forma-tion were predicted by using the technology of"structural interpretation with high precision and ancient-landform characterization"and based on interlayer interpretation.Additionally,through inversion of facies-controlled dolomite reservoirs,the spatial distribution of reservoirs was determined to facilitate the delineation of favorable intra-platform shoal zones in this Maokou Formation.Results show that the technology of facies-controlled thin dolomite reservoir prediction may effectively reflect the spatial distribution,laying a foundation for predicting the dolomite reservoirs to support well deployment and exploration and development practices in central Sichuan Basin.关键词
