摘要

The intersaliferous complex of the Pripiat basin was deposited during a rift stage that occurred at Hercynian cycle. Reef formations are locally present within this complex, proof that the basin had undergone significant variations of tectonic regime during sedimentation processes. The natural reservoirs rocks of this complex consist essentially of biogenic, bioclastic limestones and dolomites which had suffered important diagenetics transformations. The vertical succession of these reservoirs rocks point up the existence of cycles quantified by the mathematical methods of autocorrelation and spectral analysis. The application of appointed mathematical methods for interpretation of neutron gamma logs of natural reservoirs intervals allowed the structuring of studied oil fields in linear hydrodynamic blocks proved by the water injections made with intention to maintain reservoirs pressure during fields’ exploitation.
