摘要：
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. © 2018, Editorial Department OIL GEOPHYSICAL PROSPECTING.
