ON THE GEOTHERMAL CONDITIONS OF STRUCTURAL UNITS FOR ROMANIAN HYDROCARBONS
(Abstract)
Having 3070 pressure measurements in stabilized conditions and about 170 measurements
in unstabilized conditions, the authors of the present paper drew up maps
of the geothermal gradient at several levels, among which that located at
1000 m depth under the sea level is enclosed.
According to the available data, the geothermal gradient varies on the Romanian
territory between 1.5° and 7.1°C/100 m. The highest values are found
within the Pannonian Depression and the western part of the Moesian Platform,
while the smallest values are present in the Eastern half of the Moesian Platform.
The regional distribution of temperatures within the sedimentary deposits depends
on two main factors: the position of the metamorphosed basement, therefore
the thickness of sedimentary formations, and the existence or absence of some
deep tectonic disturbances.
