变压差岩心渗透率测试实验检测数据

变压差岩心渗透率测试实验检测数据委托江苏珂地仪器有限公司进行岩心放入实验装置模拟地热回灌情况。将取样岩心切割处理成25*50mm及25*80mm的岩样用于热储砂岩岩石损伤实验装置进行实验数据采集。加工处理方式为：（1）对岩心加载围压后使用不同的间隔增加岩心两端的压差，观察不同情况下岩心的渗透率规律，并观察出水中是否有出砂现象产生。（2）为了观察岩心进行一次实验后再进行水驱实验的渗透率变化。（3）对实验前后部分岩心的渗透率进行测量。实验完成了变压差岩心渗透率测试实验，江苏珂地仪器有限公司方提供检测报告用于探究雄安新区地热尾水回灌模拟方面相关研究。Jiangsu Kedi Instrument Co., Ltd. was commissioned to handle core placement and experimental setup for simulating geothermal reinjection scenarios for the variable differential pressure core permeability test experiment. The collected core samples were cut into specimens of 25×50 mm and 25×80 mm for experimental data collection using the thermal reservoir sandstone rock damage experimental apparatus. The experimental processing procedures are as follows: (1) After applying confining pressure to the cores, differential pressures at both ends were adjusted with different incremental steps. The permeability variation laws of the cores under various conditions were observed, and the presence of sand production in the effluent was detected. (2) The changes in core permeability after an initial experiment followed by a water flooding test were observed. (3) The permeability of some core samples was measured before and after the experiment. After completing the variable differential pressure core permeability test experiment, Jiangsu Kedi Instrument Co., Ltd. provided the test report for relevant research on geothermal tailwater reinjection simulation in Xiong'an New Area.
