The reservoirs of Block Yan22 in Yanjia Oilfield are classic glutenite and it becomes the hard point for reservoir study to divide the depositional stage.Based on the fundamental principle and its geological meanings of wavelet transformation and the character/stics of glutenite researvoirs,the binary wavelet of dbn series are given preference to.Continuous wavelet analysis is carried out to neutron well logging data.Make use of core image data and wavelet parameter curves with different scale to accomplish comprehensive analysis and confirm the scale factor of wavelet transformation, and for the last step,to divide the depositional stage of glutenite bodies,and the well drilling and dynamic data indicate that the depositional stage division in this way is reliable.
