geotermija vengrii. Measurements of a thermal stream

you are: geotermija vengrii

Measurement was made in verhneoligotsenovyh clay sandstones and in sandy mergeljah, blocking mesozoic karbonatnyj the base. The advanced method was applied to measurement of heat conductivity of clay adjournment. Boldizhar has come out with the assumption, that porous breeds can be modelled a combination of parallel cells and the cells connected in a series. By means of such model the heat conductivity factor in the water sated condition can be calculated on materials of measurement of heat conductivity in a dry condition and in a condition of saturation by oil. This method too is inconsistent. To bypass arising difficulties, definitions 8 and 9 have been executed in the chinks which have entered into more consolidated breeds. However definition 8 is unreliable for the reason, that the 150-metre interval of depth and that in this interval a temperature gradient very much izmenchiv has been investigated only. Definition 9 has been executed for the first time SHalatom. Recently this result has been counted taking into account more reliable data about temperature.

Measurements of a thermal stream have been executed on the Big Hungarian lowland. And again uncertainty of factor of heat conductivity has considerably affected accuracy of both received values of a thermal stream. Measurement has been made recently in attempt to overcome the difficulties connected with definition of heat conductivity of clay sedimentary breeds. The new device for heat conductivity measurement has been made. It is based on use of a method of the differentiated linear source. The flat gauge is produced from a heating thread and termistora, covered with both parties plastic plates. Samples of a core are cut on two parts, and between polovinkami the gauge is put. Measurement occupies from 20 till 100 seconds. It has been by practical consideration established, that contact thermal resistance of the water sated samples is insignificant also it it is possible to consider. If samples have lost a water part, them sate again (is better at low pressure). The technique is that, that the superficial thin layer of the sample should be completely sated only. Hence, saturation and measurement occupies all some minutes. It is supposed, that for such short interval of time in structure of clay deposits essential changes have not time to occur. The new device had been measured 25 samples sedimentary and two samples of crystal rocks from a chink 12. At definition of thermal resistance received by methods electric and nuclear karotazha data about change of the maintenance of clay with depth also have been considered. The size of a thermal stream received as a result 104 мВт/м2 is considered as more or less reliable as the established temperature was measured in a chink only.
