摘要
目前我国地下水封洞库开发现状形势严峻,在洞库储油过程中,输油、抽油和注水等作业都会诱发岩体微破裂,微震监测技术正逐渐在地下水封洞库的稳定性和安全性评价方面显示出特有的优势。通过分析微地震活动性事件来描述洞库岩体裂缝的二次活动性信息,可以判定洞库岩体的损伤程度及安全状态,进而揭示洞库岩体的变形机制。以中国石油锦州地下水封洞库工程为例,介绍了微震监测技术在地下水封石油洞库中的应用,从而为未来地下水封储油洞库的运营管理提供思路。
The development of underground water-sealed caverns stays in a grim situation in China, since microfractures are induced at rock mass in caverns by oil transportation, oil pumping and water injection during the operation of oil storage in the caverns. Accordingly, the microseism monitoring technology is gradually presenting its unique advantages in evaluating the stability and safety of underground water-sealed caverns. Based on the analysis of micro-seismic activity events, the secondary activity of the fractures are described and the damage degree and safety status of the rock mass are diagnosed, so that the deformation mechanism of the rock mass is revealed. This paper presents the application of microseism monitoring technology in Jinzhou underground water-sealed oil storage cavern of Petro China, in order to provide the reference for the development and management of future underground water-sealed oil storage caverns.
