基于原位瞬态压力脉冲法原理及求解方法,研发了由数据采集控制系统、脉冲压力施加系统、测杆系统3部分组成的小尺度原位瞬态压力脉冲渗透性测试系统(已获国家发明专利[1])。该系统结构简单、易于控制、使用方便,可用于快速原位测量核废料地下处置、能源地下储存和深埋等地下工程中低渗透围岩的渗透率以及测试空间狭窄和岩体扰动要求严格的其他工程岩体渗透率。利用该系统实施了原位瞬态压力脉冲渗透率测量试验,试验结果验证了该系统的适用性、稳定性和准确性。
Based on the principle and solution method of in situ transient pressure pulse method, a small-scale in situ transient pressure pulse permeability test system composed of three parts of data acquisition control system, pulse pressure application system and spindle measurement system has been developed Patent [1]). The system is simple in structure, easy to control and easy to use. It can be used for rapid in-situ measurement of permeability of low-permeability surrounding rock in underground engineering such as underground nuclear waste disposal, underground energy storage and deep underground engineering, as well as strict test space and rock disturbance Other engineering rock mass permeability. The system was used to carry out in-situ transient pressure pulse permeability test, the test results verify the applicability, stability and accuracy of the system.
