Geophysical Exploration Of Geothermal Resources In The Suizhong Area Of Liaoning Provice

Geohermal as a valuable renewable clean energy,its application prospect is very broad.Historically,we applied geothermal for production and life,it not only can be use to generate electricity,heating,also can be used for medical treatment,etc.Suizhong area is very rich in geothermal resources.It can accelerate the economic development of the area if we exploit geothermal resources fully.But how to exploit these potential resources efficiently is a problem need to solve.Due to the geothermal resources are usually stored in a complex fracture intersection development zone.So this article do geothermal geophysical exploration research in two measurement area in suizhong(yanjia vally and yongan),and combined with the geological stratigraphic characterisstics of measuring area to analyze.and deuce the heat reservoir fracture structure distribution preliminary and respectively.Lay a foundation for the further research and the exploitation and utilization of geothermal resources.The results of this paper as following:(1) Find out suizhong area belongs to volcanic basin geothermal type composite geothermal heat conduction convection,heat distribution controlled by lithology and geological structure.Is a deep fault belt fissure water and its heat source is associated with deep basic magma source,through the basin deep fault belt continuously supply heat up.(2) By doing the controlled source audio-frequency magnetotelluric method of geophysical exploration research in Yanjia vally and yongan area. preliminary concluded that there is a deep geothermal storage structure zone in the surveyed area Structure width is about40 m to 80 m,the direction is northwest,tend to southwest. Provide a favorable target areas for geothermal resource development in this region.(3) Yongan area measurement combined with gravity,magnetic method and controlled source magnetotelluric comprehensive geophysical prospecting method,it is concluded that there are six fault zone as the integrated integrated interpretation, but F1 is a large and the main part of water spaces and water cycle fracture in this area.(4) In order to verify and develop the geothermal resources of Yongan area,survey the location of well in this aream,survey the location of well in this area,decided the location of well and drilling depth lay the foundation for subsequrnt exploration and research.(5) Combine with Suizhong area structure and two test area to deduce geothermal structure,preliminarly conclude that the geothermal structure of mearsue area is a secondary fracture zone of Mingshui fracture. Fracture zone and fracture zone in enrichment and migration of the underground the underground hot water is very well.
