摘要为了获取北京市西集地区深部地热资源和浸部含水层间是否存在水力联系，选取研究区内的两眼地热井(西集-1 并和京通一2并）通行损水试验，并同时选取两眼地热井周边的14眼凉水并通行水位监测。试验结果表明，在对两眼地热并进行抽水试验时，周边14眼凉水并的水住未发生明显降低，暗示了深部地热水与浸部含水层并不存在水力联系。区内发育了巨厚的古近系和新近系，其岩性以混岩和粉一细砂常为主，是有效的隔水层，隔绝了深部地热水与浅部第四系凉水的水力联系。

Abstract: In order to obtain the hydraulics links between the deep geothermal resources and shallow aquifers in Xiji area, Beijing, we chose 2 geothermal wells (Xijing-1 well and Jingtong-2 well) to carry out pumping test in the studying area, and meanwhile monitor the water levels of 14 cold water wells nearby the two geothermal wells. The test results showed that there were no obvious descends of water level in the 14 cold water wells when the two geothermal wells were conducted the pumping test, implying no obvious hydraulics links existed between the deep geothermal water and shallow groundwater. The reason might be related to be the huge thick Palaeogene and Neogene Systems in the studying area which were dominated by mudstone and silt-fine sandstone. So the Palaeogene and Neogene Systems could serve as the effective water-resisting layers and cut off the hydraulics links between the deep geothermal water and the shallow Quatermary cold water

0引言
地热能是一种新型的能源和资源，同时也是绿色环保能源（卢予北等，2005）。近年来，随着大基金项目：北京市东南地区地热资源开发利用调查及评价：
气污染的加剧，对新能源尤其是清洁能源的需求和利用正在不断加大。而以深层地热能为代表的可再生清洁能源的开发利用是缓解大气污染的最有效手段之一。目前，对地热资源的开发和利用也相对比
