Based on a kind of orthogonal complete functions in L2[0,1], another one (called V-system) which has equivalence relation with U-system is created. It is a kind of new and effective mathematical tool on signal multi-resolution analysis. Besides that V-system keeps the favorable properties of U-system and can accurately reconstruct geometry information which expressed in piecewise polynomials by finite sum of functions in V-system, it has more special properties, such as simple construction, abundant levels, convenience of application, quick calculation, local support, and so on. V-system is the generalization of Haar orthogonal functions, and to be a class of wavelet base. It has a good future for some applications in the fields of wavelet analysis and signal processing.

Geophysical characteristics of Ordovician carbonate rock were studied using drilling data. Impedance is affected mostly by material properties and reservoirs types, to a negligibly extent by lithology and flow. Compact layers and minor\|fracture reservoirs of Ordovician carbonate rock have characteristics of high density, high velocity and high impedance, and the prediction of minor fractures reservoir is difficult by the general seismic ways. Big fractures and fractured\|vuggy and vuggy and cavity reservoirs of Ordovician carbonate rock have characteristics of minor density and low velocity and low impedance in central Tarim basin, which obviously different from the surrounding rock and produce obvious characteristics in seismic data, so reservoirs can be predicted by applying general seismic data.
