Kryva I. Lithomagnetic complex’s of oil-and-gas-bearing Paleozoic sediments at the north-west part of the Dnipro-Donetsk cover.

Object of study - the Paleozoic sediments at the north-west part of the Dnipro-Donetsk cover; subject of study - investigation of the magnetic susceptibility of the Paleozoic sediments at the Dnipro-Donetsk cover; aim – determination of the magnetic susceptibility oil and gas barring Paleozoic sediments at the north-west part of DDC; methods : experimental measurements; analyzes of the magnetic susceptibility of the rocks data; lithological, facial, paleontological, petrographic investigations; Practical aspects: investigations of the magnetic susceptibility give more information about petrophysics properties of the rocks. On the base of magnetic susceptibility the vertical dismembered of the layer was done and according to this parameter we can separate the lithomagnetic complex, which are basically coincide to the statographycs values. Scientific novelty: On the base of magnetic susceptibility the vertical dismembered of the layer was done and according to this parameter we can separate the lithomagnetic complex, which are basically coincide to the statographycs values. By the magnetic susceptibility values Paleozoic complex of the north-west part of Dnipro-Donetsk cover can be divided to the several lithomagnetic complexes: Devonian, lover Tournaisian, upper Tournaisian, lover Visean, upper Visean and Serpukhovian. Determined lithomagnetics complex can be recognized lateral as in the frame of one deposit and also by the line, which is crossing the South border zone, Central and Northern border zone. Differentiation of the one type sediments by the magnetic susceptibility in the frame of gas and oil complexes of Paleozoic in the north-east part of Dnipro-Donetsk cover is caused by the hydrocarbon availability. It is recommended to use the knowledge about the magnetic susceptibility in the complex with other geological and geophysical methods for the computation of the correlation and ritmostographic in oil and gas prospectings.
