| 砂岩热储是我国地热开发的主要对象，具有分布范围广、开采潜力大的优势，但回灌困难、开发过程中易衰减等问题制约了可持续开发。黄骅坳陷地质条件、研究程度及开发利用在我国砂岩热储分布区具有一定的代表性，以往研究将砂岩热储视为整体开展单井及区域回灌能力评价和回灌影响因素分析，未考虑其垂向非均质性导致的回灌能力差异，难以确定优势回灌层段。本文基于黄骅坳陷2眼馆陶组地热井井下分层监测回灌试验数据，按照馆陶组热储垂向3段划分原则，以总回灌量、单位砂层厚度回灌量为判断指标，系统分析回灌能力垂向分布规律。结果表明，馆陶组Ⅰ段为优势回灌层段，回灌能力呈现馆陶组Ⅰ段>Ⅱ段>Ⅲ段的特征。本次研究成果成功应用于出现衰减的BT06地热井中，通过在馆陶组Ⅰ段和Ⅱ段进行射孔作业，回灌能力由10 m3/h提升至62.3 m3/h，验证了研究成果的可靠性，这为沉积盆地砂岩热储的高效开发及可持续利用提供了技术支撑。 |

| The sandstone geothermal reservoirs are the primary target for geothermal development in China, which is characterized by extensive distribution and substantial potential. However, challenges such as difficult reinjection and easy attenuation constrain their sustainable exploitation. The geological conditions, research maturity, and application scenarios of the sandstone geothermal reservoirs in the Huanghua Depression are representative of sandstone geothermal reservoirs across China. However, traditional research has treated the geothermal reservoir as a homogeneous whole when conducting single-well and regional reinjection capacity assessments and analyses of reinjection-influencing factors, failing to account for variations in reinjection capacity due to vertical heterogeneity, which makes it difficult to identify the optimal reinjection intervals. This study uses reinjection test data from downhole stratigraphic monitoring of two geothermal wells in the Guantao Formation in the Huanghua Depression. Following the conventional practice of dividing the Guantao Formation reservoir into three vertical sections and using the total reinjection volume and the reinjection volume per unit sandstone thickness as core evaluation indicators, the study systematically analyzes the vertical distribution patterns of reinjection capacity. The results indicate that the Guantao I section is the dominant reinjection section, with reinjection capacity following the pattern Guantao I > Guantao II > Guantao III. The research findings have been successfully applied to the BT06 geothermal well, which has experienced a production decline. By performing perforation operations in the Guantao Formation I and II, the injection capacity was increased from 10 m3/h to 62.3 m3/h, confirming the reliability of the research results. This provides technical support for the efficient development and sustainable utilization of sandstone geothermal reservoirs in sedimentary basins. |
