摘要低渗透性的裂隙岩体是地下水封石油洞库建库的最佳选址区，裂隙网络模拟技术是研究离散裂隙渗流的有效手段。以黄岛地下水封洞库库区渗透性研究为出发点，在地表裂隙调查与钻孔裂隙统计的基础上，运用离散裂隙模拟软件DFN对洞库区进行三维裂隙网络模拟，得出模拟区导水系数分布图以及ZK13钻孔连通性分布图，通过将模拟结果与野外试验结果对比，认为模拟结果合理可信。实例分析表明，模拟结果能较为深刻地揭示裂隙水渗流的本质，可为后续的洞库水封效果及涌水量评价提供参考。

Abstract：Low permeability fractured rock is the best choice for the construction of water sealed underground oil tank. Three-dimensional fracture network simulation is an effective technical means of clarifying the essence of fracture distribution characteristics and seepage of fracture water rules for the underground project. The latest software discrete fracture network(DFN) is used to analyze the permeability of Huangdao water sealed underground oil tank based on the statistical work of field surface cracks and drilling image fracture results. Transmissibility distribution and connected compartmentalization of ZK13 are simulated in the model and the results are conceived to be reasonable and reliable through the comparison with the field test results. The example shows that the simulation results can deeply reveal the nature of fissure water seepage and could provide reference for the subsequent evaluation of water sealed effect and water inflow quantity.
