【摘要】：地下水封能源洞库是目前我国石油战略储备基地的重要工程建筑。水幕巷道的水幕钻孔布置是保障和检验洞库本身水封气密性的关键工程措施,其对应的水幕效率试验则是水封能源洞库中核心水文地质试验。目前,水幕钻孔的布置及水幕效率试验主要参考国外公司的工程经验,操作流程为初始阶段等间距布置的多阶段线性工作过程,耗费时间较长。为进行优化,依托烟台某商业储备库工程项目,从子库区裂隙统计入手,利用数值模拟软件Fracman建立了研究区离散裂隙网络,并通过立方定律求其渗透系数张量;分析了渗透系数张量特征,对水幕效率试验中的低水幕效率岩体进行了预判,并与实际试验结果进行了对比,根据一致性较好的模拟结果提出了基于离散裂隙网络模型的初始阶段不等间距的水幕钻孔布设及水幕效率试验思路。
[Abstract]:The underground water seal reservoir is the important engineering building of our country's petroleum strategic reserve base at present. The water curtain borehole layout of the water curtain tunnel is the key engineering measure to guarantee and inspect the airtight property of the water seal itself. Its corresponding water curtain efficiency test is the core water text geological test in the water seal energy cave. The water curtain efficiency test mainly refer to the engineering experience of the foreign companies. The operation process is a multi stage linear working process of the initial stage, which takes a long time. In order to optimize, relying on a commercial reserve bank project in Yantai, starting with the fracture statistics of the sub reservoir area, the discrete crack in the study area is established by using the numerical simulation software Fracman. Through the cubic law, the permeability coefficient tensor is obtained by the cubic law. The permeability coefficient tensor characteristics are analyzed and the low water curtain efficiency rock mass in the water curtain efficiency test is prejudged. The comparison is made with the actual test results, and the unequal spacing of the initial stage based on the discrete fracture network model is proposed. The design of water curtain drilling and water curtain efficiency test.
