Abstract

Commercial hydrocarbon accumulations in carbonate deposits are not usually controlled by a structural factor. Forming reservoir rocks here is often associated with the secondary processes (solution, leaching, compaction) that is responsible for the reasonably complicated structure of interstitial space of carbonate rocks (particularly in saline environment) and the insignificant change of capacity properties in transferring from non-reservoir to reservoir (sometimes percent fractions). For recognizing such fine effects, it is necessary to pass gradually from petrophysical parameters determined on well logging data, core, testing to the attributes of a seismic signal (amplitudes, energy and others). Such a procedure is carried out by the way of successive constructing the petrophysical, geoacoustic and seismic-geological models. In the case of absence of density measuring in wells, necessary for geoacoustic modeling, it is calculated on the parameters of a petrophysical model. Practical examples for concrete fields of Eastern Siberia are given
