摘要：

利用四川盆地100余口石油探井的地温资料,编制了地温梯度等值线图;并利用这些深井岩芯进行了岩石热导率的测定,获得各时代地层热导率数据58个;又选取在同一研究段既有可靠地温梯度资料又有岩芯热导率测试资料的6口深井进行了热流值计算。地温梯度及热流值均以川中为最高,向四周降低。

关键词: 四川盆地, 地温梯度, 岩石热导率, 大地热流值

Abstract:

The geothermal gradient contour chart of Sichuan Basia shows that geothermal gra-dient of Central Sichuan is 25 -30℃/kin±,and it decreases to 20℃/km in the western,northern and eastern parts of the basin.A profile showing the basin’s heat conductivity was made based on 58 data of heat conductivity measured from some deep well cores and the heat flow values of 6 deep wells were calculated as follows:D-87 well in Central Sichuan is 68.83mW/m2;D-100 well and D-96 well in Western Sichuan are 48.51mW/m2 and 52.27mW/m2;D-55 well and D-69 well in Northern Sichuan Basin is 48.03mW/m2 and 42.49mW/m2;D-82 well in Northeastern Sichuan Basin is 45.49mW/m2.The average value(50.83mW/m2)is lower than North Jiangsu,South Jiangsu and NorthChina Basin.
