| 摘要: |
| 对河北辛集井进行了50~200m深度内的井水温梯度测试，结果表明测试深度内存在3处负梯度段（50~60m处、90~110m处、130~140m处）。在50~60m深度处的水温负梯度位置，发现了清晰的水温固体潮，其相位与水位固体潮相反。根据该井的综合钻井资料、水文地质条件分析认为水温负梯度可能与井管外低温含水层热交换有关，并讨论了负梯度处的水温固体潮特征。 |

| Abstract: |
| Water temperature gradient in Xinji well has been tested from 50m to 200m deep,and the results show that there are 3 negative gradient sections(50-60m,90-110m,130-140m)in the test depth. The clear water temperature tide,whose phase is in contrast to the water level tide,has been found in 50m to 60m depth position in the water temperature negative gradient. According to the well drilling data and hydrogeological conditions,water temperature negative gradient may be associated with the cold water layer in the same depth around the well. Characteristics of the water temperature tide in the negative gradient have been discussed. |
