Discussion on optimal normalization of geophysical logging in reservoir study;

Joint application of wavelet transform and Walsh transform for automatic segmentation of well logs;

Applications of well logs to the division of stratigraphic base-level cycles;

A study on the method for the division of sequence stratigraphy automatically using well logs;

Intersection recognition of well logging curve based on discrete hopfield neural network;

Making the synthesis contrast of the well logging curve to the coal field or the exploration area by using rock coal seam geophysics characteristics and well logging curve natural horizon markers are often used in the coal field geologic report which have an important guiding meaning for the future of coal mine production.

By using well logging curves,this paper analyses the relationship among strata information and all genetic signs as well as hydrodynamic factors in relevant sedimentary environment,studying well-logging facies,sedimentary microfacies,and the distribution and development of their reservoir sandbody.
