Analysis and countermeasurement of seismic prediction in the Sulige Gas Field

Sulige Gas Field is a large but low pressure and low saturation gas field located in the Ordos Basin. The main reservoirs are of Late Paleozoic amalgamated fluvial channel sands. High-resolution 2-D seismic played a critical role in reservoir prediction and the discovery of gas fields. Data acquisition, quality, processing and interpretation in recent years are reanalyzed to improve the predictability of future work. To meet the ever increasing gas field development demand, it is suggested here to apply 3-D pre-stack seismic attributes analysis, well-logging, strata time-frame constraint, reservoir inversion and elastic wave inversion technology, 3-D VSP and 3-C seismic techniques in future work.
