水封性评价是地下水封石油洞库建设的关键科学问题。围绕地下石油洞库水封性评价,提出了地下水封石油洞库水封性评价的水文地质概念模型,总结了水封性评价中地下水、岩体性质与地质环境和洞库工程特征3个方面基础数据,分析了三者之间关系;分析了经验法、数值分析法和试验法三大类评价方法的特点和对应的适用范围,提出了评价方法“三适应”选用原则:评价方法与建设阶段、评价目标和参数要求相适应,提出了水封性评价流程,分析了不同评价阶段所应采用评价方法和重点的评价内容;以具体工程为背景,介绍了评价方法体系的应用情况,并着重介绍了经验法、裂隙网络法和现场试验法在水封性评价中的使用情况。研究成果对提高地下水封石油洞库水封性评价水平具有重要参考价值。
Seabed evaluation is a key scientific issue in the construction of underground caverns. Based on the evaluation of water seal of underground oil reservoir, this paper presents a conceptual model of hydrogeology for water seal evaluation of underground sealed oil reservoir, summarizes three aspects of groundwater, rock mass properties and geological environment and characteristics of underground reservoir in water seal evaluation Based on the analysis of the relationship between the three; analysis of the empirical method, numerical analysis and test method of the three major characteristics of the evaluation method and the corresponding scope of application of the evaluation method “three adapt ” selection principle: evaluation method In accordance with the construction stage, the evaluation objectives and the requirements of the parameters, a water seal evaluation process was proposed, and the evaluation contents of the evaluation methods and key points to be adopted in different evaluation stages were analyzed. Based on the concrete projects, the application of the evaluation method system was introduced , And emphatically introduced the use of experience method, fissure network method and field test method in water seal evaluation. The research results have important reference value for improving the water seal evaluation of underground oil sealed caverns.
