河南省永城市顺河西矿区地温分布规律研究

对永城市顺河西矿区内2个近似稳态测温和44个简易测温数据进行分析，并结合矿区地质资料，通过数据拟合，建立数据模型，反映了矿区内似稳态测温钻孔孔底温度增量ΔT与钻机静井时间t的关系.根据数据模型校正了简易测温钻孔的孔底温度，通过数据拟合发现矿区埋深与温度之间的线性关系.在此基础上，从横向上和纵向上分析了顺河西矿区的地温分布规律，为下一步矿山开发提供参考依据.

GEOTHERMAL DISTRIBUTION RULE OF SHUNHEXI OREFIELD IN YONGCHENG CITY,HENAN PROVINCE

The paper analyzes the data for approximate steady state temperature measurements of 2 boreholes and simple temperature measurements of 44 boreholes in Shunhexi orefield of Yongcheng City, and establishes data model through data fitting combined with the geological information of orefield to reflect the relationship between temperature increment at the bottom of approximate steady state boreholes and static well time. The bottom temperature of simple temperature measurement borehole is corrected according to the data model, and the linear relationship between buried depth and temperature is found through data fitting. On this basis, the horizontal and vertical distribution law of geothermal temperature in the study area is analyzed for reference of further mining development.
