city natural gas reserves的意思|示意

But it is what is under the city that really sets it apart: massive reserves of natural gas.

但真正让这座城市与众不同的，是它地底下的东西：储量巨大的天然气。

Leakage, a serious problem, often occurs in the exhausted underground natural gas storage built around the city during its running period, which results in less actual reserves than that of account.

利用城市附近枯竭气藏建立的用于调峰的地下储气库，在运行过程中常发生渗漏，导致地下储气库的实际存气量低于帐面上的存气量。
