地下水封石油洞库水幕系统水力试验及水幕钻孔施工

水幕系统是地下水封储油库最为关键的部分,主要由水幕巷道、水幕孔、附加水幕孔、监测井和仪表井组成。水力试验成果是水幕系统评价的依据,而水幕孔的施工质量又是水力试验顺利和试验效果的保证。结合辽宁某地下水封洞库工程,阐明了水幕系统在施工期间的水文试验方法,分析了施工期间各水文试验的作用及其相关性;介绍了水幕钻孔施工技术。

Hydraulic Test of Water Curtain System for Underground Water-sealed Oil Storage Cavern and Water Curtain Drilling Construction

Water curtain system is the most critical part of underground water-sealed oil storage, which is composed mainly of water curtain channel, water curtain hole, additional water curtain holes, monitoring well and instrument well. The results of hydraulic test are the basis of the water curtain system apprising and the construction quality of water curtain hole is the guarantee of hydraulic test and the test results. According to the project of an underground water-sealed oil storage cavern in Liaoning, the paper explains the hydrological test method during the water curtain construction, analyzes the function and correlation of each hydrological test during the construction and introduces the construction technology of water curtain hole.
