摘要:

辽河盆地是一个中、新生代断陷盆地,具有“三凹三凸”的构造格局.依据 1 2口系统测温井数据和 47块岩石热导率测试结果,计算了东部凹陷 1 2个高质量的大地热流数据.东部凹陷地温梯度变化于 10~ 50℃/km之间,岩石热导率变化于 0.819~ 2.914W /m·K之间,平均 1.667W/m·K,热流值变化于 45.7~ 70.0×10-3W/m2 之间,平均为56.1(±6.98)×10-3W/m2.热流分布的格局是古潜山带和斜坡带高于洼陷区.

Abstract:

The Liaohe Basin is a Meso-Cenozoic faulting-depression basin, characterized by tectonic framewo rk of “three subdepressions and three uplift s”.Based on temperature measurements in 12 w ells and thermal conductivity determinations of 47 rock samples, 12 heat flow values w ere calculated for the Eastern Subdepression.The geo thermal g radient ranges f rom 10 ℃/ Km to 50 ℃/Km.The rock thermal conduct ivity ranges f rom 0.819 W/m·k to 2.914 W/m·k.Ranging f rom 45.7 mW/m2 to 70.0 mW/m2, the mean of these 12 heat flow values exhibi ts 56.1 ±6.98 mW/m2.The heat f low in the uplif t and ramp is g reater than that in the sag.

Key words: Borehole geothermal g radient, Thermal conductivity, Heat f low, Eastern subdepression of Liaohe Basin
