Application of the Frequency Information of Seismic Data in Predicting Sandstone Reservoirs
地震数据体的频率信息在岩性预测中的应用——以松辽盆地孤店地区泉四段为例

Reservoir geological information can be predicted effectively by abundant geophysical information in seismic data, which include amplitude, frequency, phase, wave, etc. Based on the fine frequency spectrum analysis and the test of filter scan, this paper studies the sensitivity of different frequency signals and different strata thickness and establishes the correlation between drilling lithology and the tune amplitude of different frequencies. Through adjusting different frequency times and processing the frequency spectrum of seismic data, the efficiency frequency can be used to predict lithology effectively in seismic inversion and attributes analysis. By this method, the main oil reservoirs of different layers of the Quan 4 member were successfully predicted and analyzed in the Gudian area.
