地下水封石洞油库设置水幕系统必要性研究

Necessity of Water Curtain for Water-sealed Underground Oil Storage Cavern

水幕系统是地下水封石洞油库(简称"地下水封洞库")的重要组成部分,它的设置与否将直接影响到地下水封洞库的水封效果。因为水幕系统施工难度大,工期长,工程量大,所以业界对于地下水封石洞油库是否有必要设置水幕没有形成一致意见。结合国内外地下水封石洞油库的工程经验,根据在建某洞库的水文地质及工程地质条件,运用ABAQUS软件进行计算,客观地阐述了设置水幕系统的必要性,可为以后地下水封石洞油库的规划和建设提供可靠的决策支持。

Water curtain system,as an important part of underground water-sealed oil storage cavern,directly affects the effect of water seal.As water curtain system is difficult to construct with long duration and large work load,there＇ s no consensus yet on the necessity of water curtain.According to experiences of underground watersealed oil storage cavern in China and abroad,we expounded the necessity of water curtain system by using ABAQUS calculation software in consideration of the hydrological and engineering geological condition of an oil cavern under construction.This research provides support for the decision-making of planning and construction of underground water-sealed oil storage cavern.
