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 1 0～ 5 0℃/km之间 ,岩石热导率变化于 0 81 9～ 2 91 4W /m·K之间 ,平均 1 667W/m·K ,热流值变化于 45 7～ 70 0× 1 0 - 3W/m2 之间 ,平均为5 6 1 (± 6 98)× 1 0 - 3W/m2 .热流分布的格局是古潜山带和斜坡带高于洼陷区 .
Liaohe Basin is a Mesozoic-Cenozoic fault basin with “three-concave and three-convex” tectonic framework.According to 12 well-system temperature well data and 47 rock thermal conductivity test results, 1 2 high The geothermal gradient of the eastern depression varies from 10 to 50 ℃ / km, and the thermal conductivity of the rocks varies from 0 81 9 to 2 91 4 W / m · K with an average of 1 667 W / m · K , The value of heat flow varied from 45 7 to 70 0 × 10 3 W / m 2 with an average of 5 6 1 (± 6 98) × 10 3 W / m 2 .The pattern of heat flow distribution was between the buried hill and the slope Above the depression area.
