| 摘 要： | 在明确小平岛地质背景的基础上,分析地热地质条件并判断地热资源类型,结合已有两眼井S1、S2数据资料,采用热储法对其地热资源进行潜力评估。结果表明,大连市小平岛地区为深层传导型地热资源,该区桥头组及长岭子组上部为良好地热盖层,长岭子组下部及南关岭组上部(2 100~3 300 m)为该区热储层,热储体面积为7.3 km2。单井涌水量可达600~800 m3/d,水温可达50℃~60℃,地热资源量约为4.88×1011kcal,折合标准煤为6.97×107t,可开采的地热资源量约为7.32×1010kcal。

| Abstract: | Based on the analysis of the geological background of Xiaoping Island， the authors analyzed the ge- othermal geological conditions and determined the type of geothermal resources，combined with existing wells data． Thermal energy storage method was used to assess its potential for geothermal resources，and the results showed that the geothermal resources was deep geothermal resource type in Dalian Xiaoping Island area． The Qiaotou Formation and upper Changlingzi Formation were geothermal well cover， and lower Changlingzi Formation and upper Nanguan- ling Formation (2 100 ～3 300 m) were geothermal reservoir，which reservoir body is 7. 3 km 2 in area． Single well water can reach 600 ～800 m 3 /d，with water temperature of 50℃ ～60℃，and the geothermal resource quantity can reach about 4. 88 ×1011 kcal，equivalent to standard coal of 6. 97 ×107 t． Thus the exploitable geothermal resources can be about 7. 32 ×1010 kcal in quantity． |
