| 中文摘要: |
| 苏北盆地含有丰富的地热资源,由于上覆巨厚的松散沉积层,深部地质构造、地热条件不确定性较强,找矿难度巨大。为合理、经济地开发江苏月亮湾地区深部地热资源,在系统分析月亮湾地区地热地质背景的基础上,选定八滩—小街断裂(F5)附近为重点开发区段,通过开展3条CSAMT剖面测量,经成果解译选定地热钻井井位1处。地热钻井验证结果显示,该井出水量为2171.28 m3/d,水温50.5℃,实际出水深度主要在1200～2919 m,与CSAMT解译成果相吻合,证实了CSAMT的有效性,为具有类似地热地质背景条件的其他城市及其周边寻找地热资源提供了可借鉴的勘查手段。 |
| 英文摘要: |
| The Subei Basin is rich in geothermal resources, which is difficult to find because of the uncertainty of deep geological structure and geothermal conditions due to the huge thickness of loose sediments overlying it.In order to rationally and economically develop the deep geothermal resources in the in Yueliangwan bay area of jiangsu province, on the basis of systematic analysis of the geothermal geological background in Yueliangwan area, the area near Batan-Xiaojie fault (F5) is selected as the key development section, and one geothermal well site is selected through three CSAMT profile surveys. The geothermal drilling verification results show that the water output of the well is 2171.28 m3/d, the water temperature is 50.5 ℃, and the actual water output depth is mainly 1200-2919 m, which is consistent with the interpretation results of CSAMT, which confirms the effectiveness of CSAMT. It provides a useful exploration method for other cities with similar geothermal geological background conditions to search for geothermal resources. |
