摘要
The target sandstone layers of Dongying Formation in eastern slope area of Chengdao Oilfield can not be distinguished because the thickness of sandstone reservoir is thin,the velocity difference between sands and mudstone is small,the quality of seismic data is poor and the difficulty of reservoir description is great.From the basic principle of wavelet frequency division processing,the feasibility of technique for improving the resolution of seismic data is elaborated.The reservoir distribution space and law of Dongying Formation in eastern slope area are inverted,described and predicted by the wavelet frequency division processing and logging constrained inversion.The application results show that the main frequency is increased,the band of frequency is further widened,the quality of seismic data is obviously improved and the identification of thin layer is strengthened by the wavelet frequency division processing.On this basis,the features of reservoir distribution and reserves scale are delineated with logging constrained inversion technique.Furthermore,the difficulties of reservoir prediction are effectively solved,which can provide a reliable basis for further exploration and development of Dongying Formation in eastern slope area.
