活动中，与会各方共同签订了《党建共建协议书》。各党支部书记、支委就各自党支部工作开展情况、党建与生产经营工作融合情况等进行深入交流，确定了“创新主导、资源整合、互利共赢、共同提高”为共建方向。各方就东沽能源运行部地热井回灌能力建设、地热资源高效开发利用技术创新、实现环保与经营工作双赢、加快形成新质生产力等方面工作进行充分研讨。

技术创新方面，地热回灌技术研究所党支部详细介绍了在东沽某回灌井开展的井下分层多参数监测回灌的运行情况。该项试验可以精确识别热储内回灌流体运移特征及回灌流体走向，获取回灌渗流通道数据，明确砂岩热储各分层的回灌能力，建立砂岩储层回灌主渗流层位优选标准，为解决相关技术难题，确保地热能绿色高效利用提供了支撑。

During the event, the participants jointly signed the Agreement on Party Building. Party branch secretaries and party committees conducted in-depth exchanges on the work development of their respective party branches, the integration of party building and production and management work, and determined the direction of "innovation leadership, resource integration, mutual benefit and win-win, and common improvement". All parties have fully discussed the construction of geothermal well recharge capacity of Donggu Energy Operation Department, technical innovation of efficient development and utilization of geothermal resources, win-win situation of environmental protection and management, and accelerating the formation of new quality productivity.

In terms of technological innovation, the Party branch of the Institute of Geothermal Recharge Technology introduced in detail the operation of the underground stratified multi-parameter monitoring recharge carried out in a recharge well in Donggu. The experiment can accurately identify the migration characteristics and direction of the recharge fluid in the heat storage, obtain the data of the recharge percolation channel, clarify the recharge capacity of each layer of the sandstone heat storage, and establish the optimal criteria for the main percolation layer of the sandstone reservoir, which provides support for solving relevant technical problems and ensuring the green and efficient utilization of geothermal energy.
