The Technologic Research and Application of Frequency-Divided Inversion in SL Oilfield

Abstract:

Differing from the current inversion methods, the frequency-divided inversion is depend on well logging and seismic data, using the methods of support vector computer to study the amplitude response in different detective frequencies (amplitude versus frequency, simply called AVF), taking AVF as independent information of inversion and creating the non-linear mapping relationship between wave impedance curves of logging data and seismic waveform, fully using the information of low, medium and high frequencies in seismic data to reduce the inversion uncertainty and get a higher resolution result. Frequency-divided inversion is also a high resolution seismic inversion method which no needs wavelet extraction and prior model.
