Constrained sparse spike inversion and application
The sparse impulse impedance inversion does not depend on any model but on the characteristics of original data, and can be used to predict the reservoir lithology and spreading regularity more accurately in such places where the exploration level is low, and has some guiding significance in further exploring and developing oil fields and lowers the risk of exploration. In this paper, the fundamental principles and the following key points in inversion were introduced: log standardization, wavelet extraction, inversion parameter choose and so on, and inversed impedance of ED clasolite reservoirs in J27 oilfield using this method and obtained the absolute wave impedance. The development belts of sand bodies as well as lithologic traps were located, and good inversion result was obtained.
