Approximate steady state correction of simple well temperature curve：with LYL mine field as an example
摘要
Abstract
With LYL mine field as an example, through collecting the geothermal and meteorological data in adjacent area, in combination with simple temperature measurement and approximate steady state temperature measurement, the parameters were determined in the zone of constant temperature and at the neutral point in the mine field. Firstly approximate steady temperature measurement of 3 boreholes was applied to set up the model of well temperature recovery curves, then the model was used to conduct correction of bottom temperature of the boreholes of different types for simple temperature measurement, finally from the temperature at the constant temperature point and the neutral point as well the corrected recovery temperature at the borehole bottom, the fitting equation of the correction curve for simple temperature measurement was deduced, based on the equation, the temperature measurement results of all boreholes for simple temperature measurement were corrected, the temperature of coal seam floor and the geothermal gradient of all boreholes were calculated, thus providing the first-hand data for the study of the geothermal distribution in the mine field.关键词
