Abstract

SYNTHETIC GEOPHYSICAL PROFILE OF MESOZOIC FORMATIONS IN BORE HOLE JARONOWICE

Summary

The present author proposes to apply a method of elaborating materials obtained from drilling geophysics. The example presented in the paper is based on the geophysical picture of the Mesozoic formations pierced through by bore hole Jaronowice IG-l. On the basis of both geological data and geophysical profile, geophysical complexes have been distinguished, for which an ample geophysical-characteristic has been given. This characteristic comprises the following properties of rocks: radiometrical (dIg, dIng), thermal (G, z), electrica1 (Rn, Rt, R, l) and mechanical (d/dn) properties. The geophysical picture of the formations considered is helpful in lithostratigraphical, seismical and geoelectrical elaborations, as well as in qualitative interpretation of reservoir rock features, and in correlation of physical properties between two bore holes. Fig. 1 (see Polish text) presents both the stratigraphy and the diagrams that demonstrate some physical properties of the geophysical complexes distinguished in the Mesozoic formations pierced by bore hole Jaronowice IG-I.
