松辽盆地林甸地区地温场特征

Geotemperature Field Characterastics In Lindian Region of Songliao Basin

林甸地区是松辽盆地内热水井分布最集中的地区．为了弄清林甸地区地热源的形成机制，采用盆地模拟方法计算出大地热流值，划分出大地热流值分布高值区，总结出地温分布的主要影响因素．研究区内林甸构造具有高大地热流值、高地层温度和高地温梯度等热源特征．莫霍面、居里面埋藏相对较浅，深大断裂做为沟通深部热源与上部热储的通道，巨大的花岗岩地体。

Geothermal water can be applied widely to heating, bathing, health care, planting and breeding industries. Thermal source is a key element in the geothermal system. In order to ascertain the forming mechanism in Lindian region, we applied basin simulation method to calculate the earth heat flow high value area and sum up effect factors of high value geotemperature distribution. There is a characteristic of earth heat flow value and high geotemperature in Lindian structure.Effect factors of geotemperature are that Moho and Curie are buried shallower,deep faults connects thermal source to thermal reservior,there is a huge granite body underground.
