Abstract：In recent years,the proved reserves of Mahu Sag in Junggar Basin are mostly from fan-delta conglomerate reservoirs.The three key issues in oil and gas exploration are fan body and its boundary identification,high-quality reservoir prediction,and strike-slip fracture identification.With integrated processing and interpretation tools provided by GeoEast System,the prestack high-fidelity noise suppression and multiple removal on logging and seismic data are mainly used to improve seismic data quality.On this basis,fan-bodies and its boundaries are determined with the "trinity" comprehensive seismic geological interpretation.Prestack and poststack inversions are used to predict reservoir development zones with good physical properties.Multi-attributes are used to identify strike-slip faults.After this processing,the apparent frequency of targets is increased by 10-15Hz.6 fan-bodies and their boundaries are identified rather than 4 from previous geological understanding.Based on our applications in Mahu Area,GeoEast System provides important technical supports for the conglomerate exploration,evaluation,and development,and makes remarkable achievements.
