Abstract:

The tight sandstone reservoir is developed in the eighth member of Shihezi Formation in Su Xblock of Sulige Gas Field. The reservoir has the characteristics of lowporosity, lowpermeability, lowabundance and strong heterogeneity. It has complex overlapping pattern of sand bodies, complex gas and water relationship and non-uniformair-water interface between gas and water-bearing sands. Howto apply seismic technology to predict favorable gas-bearing areas becomes one of the main problems in this block. Based on comprehensive analysis of reservoir geologic features and geophysical characteristics, this paper explored the “two step inversion” technology for predicting favorable gas-bearing areas. Firstly using frequency division inversion method to predict sand body enrichment area, and then using wave impedance inversion to predict gas-bearing properties of the sand, and finally combining the two methods to predict favorable gasbearing areas of the eighth member of Shihezi Formation in Su X block. The practical application indicates that this method reduces the multiple solutions and improves the accuracy of prediction, and can be used to predict favorable gas bearing area effectively.
