典型的井口

油气场典型的井口

在石油和天然气场的开发领域,典型的井口设备是关键设备,可确保安全有效的石油和天然气提取。以KQ78-105井口设备为例,该设备主要用于从超高压力,高硫的油气井中提取油气和天然气。它于2013年首次在塔里姆油田(Tarim Oilfield)上使用。它的衣架可以密封并悬挂管绳;圣诞树主要通道中的剪切安全阀可以剪切钢丝绳和装甲电缆;其他闸阀和安全阀可以切断并密封管道;末端节气门阀用于控制和调整井口压力和流动。
通常,气体生产井口设备需要遵守API Spec 6A和GB/T22513-2013标准,并有权使用API字母组合。它们适合在不同的工作条件下提取各种定向井和水平井。油管头的通用直孔设计有助于安装各种规格的管吊架,并且可以设计完整的千斤顶螺丝组件,以固定反磨损套筒和衣架。直孔设计的45°肩膀具有较大的轴承能力。螺柱法兰的侧面插座配备了VR塞,可以替换侧翼阀的压力。可以通过切割现场的套管以适应密封装置的高度来安装底部的BT型或P型辅助密封机构,并且测试接头和油脂注入接头都采用金属对金属密封。

水井典型的井口

在每日供水方面,水井头也具有典型的特征。例如,在Quangang区发现的歌曲王朝“ Dajie Ancestral Well”有一个由7个垂直花岗岩条制成的井口,形成了一个不规则的Heptagon,高0.51米,从下到顶部略微逐渐变细。石带的外侧是平坦的,内侧是粗糙的,在中国的井历史中很少见到一个独特的井口。

下水道井典型的井口

城市地下管道上的人孔头也是代表。人孔可以分为排水器,供水人孔,电缆人孔,通信人孔,气口孔等。它们的井口形状通常是正方形的和圆形的。圆形的人孔主要使用,当管道直径较大并且有许多分支管道时,使用方形人孔。在材料方面,有砖砌的人孔,塑料孔,混凝土人孔,铸铁人孔等。人孔盖通常由灰色铸铁,延性铁,铸钢,滚动钢,聚合物等制成。封面的中心都带有诸如“供水供应”,“污水”,“雨水”,“雨水”或“火力”的标记。
