java简写天然气储量管理系统

---

前言

简单的实现了对数据的增添、删除、根据不同要求的查找

一、要求

中国天然气资源主要分布在几个大的气区，如塔里木盆地、四川盆地、柴达木盆地和陕甘宁盆地等；各个气区由多个气田组成，如塔里木盆地由克拉 2 气田、迪那 2气田、克深气田等组成，四川盆地由普光气田、龙王庙组气藏、涪陵页岩气田、元坝气田等组成，柴达木盆地由涩北气田等组成，陕甘宁盆地由苏里格气田、靖边气田、大牛地气田组成。

请你设计一个简单的天然气储量管理系统，能够增删气田，能按气区浏览和查询气田数据，能分别按气藏类型或埋深类型汇总得到不同气区和中国的天然气储量

气田数据表格式如下所示：
气田名 气区 气藏类型 埋深类型 储量(亿方)
苏里格 陕甘宁盆地 常规气 中浅层气 5336.5

二、代码
