地热盖层中井温梯度与地温梯度的关系及应用

Relationship and Application of Well Temperature Gradient and Ground Temperature Gradient in Geothermal Covering

摘要:

在曲阜市地热地质普查中发现了井温梯度与地温梯度的关系,从理论与实际勘探工作中充分说明和验证了地热盖层地温与井温梯度差的客观存在规律。井温梯度同比于地温梯度,井温梯度与地温梯度存在一固定差值,地温梯度与井温梯度之差为2.6℃/hm。

Abstract:

Relationship between well temperature gradient and ground temperature gradient was found in geothermal geology survey of Qufu city. Occruing rule of ground temperature and well temperature gradient in geothermal covering is introduced in this paper. That is, comparing well temperature gradient with ground temperature gradient, there is a fixed deficit, and the dificit is 2.6℃/hm.
