河北省观测的高压自流热水井大都分布在冀中拗陷,观测水层为岩溶裂隙水。形成本区高压自流热水的基本条件有以下五个方面: 1.本区古岩溶非常发育,构成了深部热水的理想储存场所; 2.基底和壳层断裂发育,新构造运动的影响甚为明显,有利于深部热水的循环; 3.本区是新生代的强烈沉降区,也是上地 Most of the high-pressure hot-water wells observed in Hebei Province are located in the Jizhong depression, and the observed water layer is karst fissure water. The basic conditions for forming the high-pressure gravity hot water in this area are as follows: 1. The ancient karstification in this area is very well developed and constitutes an ideal storage place for deep hot water. 2. The rupture of basement and shell and the influence of neotectonics Is obvious, is conducive to deep hot water cycle; 3. This area is a strong Cenozoic subsidence area, but also on the ground
