Standard definitions of a thermal stream. The given definitions of a thermal stream in territory of Hungary which have been measured by the standard ways. From walls shtrekov were numerous samples lejasovyh mergelej and sandstones are taken. Their heat conductivity is measured by a method of the divided core. Temperature rhzmerjalas in a face of one or two deep chinks drilled in walls shtrekov. Was considered, that the temperature measured thus is close to temperature of rocks in a natural condition. Other two values of a thermal stream in mountains Mechek have been defined in the chinks drilled in the Perm sandstones and conglomerates. Definition has high accuracy (an error less than 10%) and will well be co-ordinated with definition which is based only on the several samples taken within a small interval on depth.

Measurements with 5 on 9 are executed within the central Hungarian ridge, i.e. In mesozoic karbonatnom a complex or over it Measurement 5 (Nadlendel) clearly shows all difficulties which it is necessary to face at definition of thermal streams in Hungary. Hundreds deep petroprospecting chinks on craft Nadlendel have allowed to learn well local geological and geothermal conditions. Strongly shattered mesozoic complex, karbonatnye breeds and mergeli, is blocked by thickness neogenovyh - chetvertichnyh adjournment by capacity about 2000 m. From two next chinks 12 samples of sedimentary breeds have been selected: nizhnepannonskie and miotsenovye mergeli and sandstones. As the natural condition of the clay adjournment sated with water will be broken, in situ it is impossible to measure their heat conductivity by a method of the divided core. In Nadlendele all samples were measured in a dry condition. Four samples of sandstone have been still measured and in the water sated condition. On this basis the relation of heat conductivity in dry and in a damp condition has been calculated. The assumption has been made, that the same relation is suitable and for clay deposits. However SHtegena has called into question correctness of this assumption. Besides, it has specified, that two mentioned chinks are in a zone of local indignation of a temperature field which is presumably connected with hydrothermal circulation. Nevertheless, in Nadlendele it is impossible to consider definition of a thermal stream unreliable. Fortunately, the reasons of various errors counterbalanced each other, therefore the size 84 мВт/м2 is quite satisfactory. This conclusion proves to be true the definition 6 which done nearby and have given size of a thermal stream 92 мВт/м2. Last value has been defined in gidrotermalno nz indignant mesozoic karbonatnom a complex on depth of 3100-5100 m.
