A laboratory analogue experiment platform with an artificial fracture was built to analyze the effect of slug interference tests on the evaluation of the hydraulic properties of fractured rocks. The response of an aquifer to a slug source well was analyzed using type-curve comparisons under the condition of different radial constant-water-head boundaries. The injecting-water, releasing-water, and pneumatic laboratory experiments of the slug interference tests were conducted in an artificial fracture. The relationship between the critical distance of the radial constant-water-head boundary and the dimensionless storage coefficient approximately followed a power function. The empirical formula provides an intuitive and effective reference criterion for considering the influence of the radial constant-water-head boundaries during field slug interference tests. When the radial constant-water-head boundary distances are less than the critical values, the boundary leads to an obvious increase in the recovery rate during the late response period, and the response peaks of the aquifer shift to an earlier time in the low-storage fractured rocks. The monitoring and analysis of the response in fractured rocks can improve the accuracy of the transmissivity and storage coefficient estimations, particularly when the slug interference tests are affected by the radial constant-water-head boundaries.

建立了带有人工裂缝的实验室模拟实验平台，以分析弹头干涉测试对裂缝岩的水力特性评估的影响。在不同的径向恒定水头边界条件下，通过类型曲线比较分析了含水层对段塞源井的响应。在一个人工裂缝中进行了段塞干扰试验的注水，放水和气动实验室实验。径向恒定水头边界的临界距离与无因次存储系数之间的关系近似遵循幂函数。该经验公式为在田field干扰测试期间考虑径向恒定水头边界的影响提供了直观有效的参考标准。当径向恒定水头边界距离小于临界值时，边界会导致响应后期的采收率明显增加，而含水层的响应峰值在低响应时移至较早的时间。储存破碎的岩石。监测和分析裂隙岩中的响应可以提高透射率和储层系数估计的准确性，特别是当弹头干涉试验受到径向恒定水头边界的影响时。边界导致响应后期，采收率明显增加，在低储层裂缝岩中，含水层响应峰值向较早时间偏移。监测和分析裂隙岩中的响应可以提高透射率和储层系数估计的准确性，特别是当弹头干涉试验受到径向恒定水头边界的影响时。边界导致响应后期，采收率明显增加，在低储层裂缝岩中，含水层响应峰值向较早时间偏移。监测和分析裂隙岩中的响应可以提高透射率和储层系数估计的准确性，特别是当弹头干涉试验受到径向恒定水头边界的影响时。
