地下水封洞库选址探索与研究
摘要:地下水封洞库是近年来国内兴起的一种新的储油方式。选择合适的库址对该工程是非常重要的环节。本文拟对照烟台万华地下水封LPG 洞库的选址勘察,结合洞库现已开挖阶段的地质条件,为国内其他洞库的选址提出可行的具体参考方案,并对目前洞库选址方法进行评价,并提出建议。

Abstract: the underground cavern in China in recent years is the rise of a new storage mode. Select the appropriate storage location for the project is a very important link. This paper is intended to control Yantai Wanhua underground LPG cavern sitting investigation, combined with the tunnel excavation is now stage of the geological conditions, the other depot location presents feasible specific reference scheme, and the depot location methods for evaluation, and puts forward some suggestions.

1、地下水封洞库的储油原理
地下水封洞库处于稳定的地下水位线以下一定的深度(5m为宜) ,通过人工在地下岩石中开挖出一定容积的洞室,利用稳定地下水的水封作用密封储存在洞室内的石油。洞室开挖前,地下水通过节理裂隙等渗透到岩层的深部并完全充满岩层空隙。当储油洞库开挖形成后,周围岩石中的裂隙水就向被挖空的洞室流动,并充满洞室。在洞室中注入油品后,油品周围会存在一定的压力差,因而在任一油面上,水压力都大于油压力,使油品不能从裂隙中漏走。同时利用油比水轻,以及油水不能混合的性质,流入洞内的水则沿洞壁汇集到洞底部形成水垫层,可由水泵抽出,原理示意图如(图1) 。
