Application of Seismic Reservoir Prediction Technology to Su-54 Block in the West of Sulige Gasfield
【Abstract】 The eighth member of Upper Paleozoic Lower Permian Xiashihezi formation in Su-54 block is the main gas reservoir of the block, and it belongs to sandstone lithologic gas reservoir. The reservoir is tight and severely heterogeneous. Effective reservoirs are thin and their distribution is dispersed. The gas-rich regions in the studied area are not understood and therefore there are difficulties in the development of the reservoir. For this reason, the reservoir thickness, the effective reservoir thickness and the gas-bearing feature of the main target segments are predicted using AVO hydrocarbons detection and pre-stack parameter inversion, and the gas-rich regions are optimized based on the comprehensive evaluation of the reservoir. 54 development wells are arranged according to the seismic reservoir prediction results. The proportion of Ⅰ + Ⅱ type wells in development phase is higher than in exploration phase,and a good development result is achieved. The development practices in Su-54 block show that the use of seismic reservoir prediction technique is very effective and is worth drawing in the development of similar gas reservoirs.
