【摘要】 吉林省长春市西北部地热资源勘探的目的在于了解勘查区地质构造,了解可供开发利用的地热资源可能赋存区域。采用二维地震反射波方法勘查,主要解释了T2反射波和T5反射波。T2反射波相当于白垩系泉头组一段底界面反射波,T5反射波相当于中生界侏罗系基底反射波。结果表明,勘查区总体为一走向近北东向的复式单斜构造,倾向北西。区域性壳断裂F1断层是勘查区内最大断层,其次是F8和F9断层长期活动。使地壳内部的余热向上传导,由F8和F9断层构成的东南地堑带是勘查区内最有利的热储构造带,F6断层以南是最佳热储构造位置。白垩系泉头组一段为勘查区内主要热储层。更多还原

【Abstract】 The aim of geothermal resource exploration in northwestern Changchun City area, Jilin Province is to find out geological structures in exploration area and possible hosting area of geothermal resources can be exploited and used. The 2D seismic reflection method can mainly interpret T2 and T5 reflections. The T2 reflection has reflected Cretaceous Quantou Formation first member bottom boundary, while the T5 Jurassic basement. As a whole, the area is a near NE compound monocline, dip NW. Regional crustal fault F1 is the largest fault in the area, then long term activating F8 and F9. They made remaining heat in crust conducting upward. The southeastern graben belt formed by F8 and F9 is the optimistic geothermal reservoir structure belt, to the south of fault F6 is the best geothermal reservoir structure locality.更多还原
