典型的井口

油氣場典型的井口

在石油和天然氣場的開發領域,典型的井口設備是關鍵設備,可確保安全有效的石油和天然氣提取。以KQ78-105井口設備為例,該設備主要用於從超高壓力,高硫的油氣井中提取油氣和天然氣。它於2013年首次在塔里姆油田(Tarim Oilfield)上使用。它的衣架可以密封並懸掛管繩;聖誕樹主要通道中的剪切安全閥可以剪切鋼絲繩和裝甲電纜;其他閘閥和安全閥可以切斷並密封管道;末端節氣門閥用於控制和調整井口壓力和流動。
通常,氣體生產井口設備需要遵守API Spec 6A和GB/T22513-2013標準,並有權使用API字母組合。它們適合在不同的工作條件下提取各種定向井和水平井。油管頭的通用直孔設計有助於安裝各種規格的管吊架,並且可以設計完整的千斤頂螺絲組件,以固定反磨損套筒和衣架。直孔設計的45°肩膀具有較大的軸承能力。螺柱法蘭的側面插座配備了VR塞,可以替換側翼閥的壓力。可以通過切割現場的套管以適應密封裝置的高度來安裝底部的BT型或P型輔助密封機構,並且測試接頭和油脂注入接頭都採用金屬對金屬密封。

水井典型的井口

在每日供水方面,水井頭也具有典型的特徵。例如,在Quangang區發現的歌曲王朝“ Dajie Ancestral Well”有一個由7個垂直花崗岩條製成的井口,形成了一個不規則的Heptagon,高0.51米,從下到頂部略微逐漸變細。石帶的外側是平坦的,內側是粗糙的,在中國的井歷史中很少見到一個獨特的井口。

下水道井典型的井口

城市地下管道上的人孔頭也是代表。人孔可以分為排水器,供水人孔,電纜人孔,通信人孔,氣口孔等。它們的井口形狀通常是正方形的和圓形的。圓形的人孔主要使用,當管道直徑較大並且有許多分支管道時,使用方形人孔。在材料方面,有磚砌的人孔,塑料孔,混凝土人孔,鑄鐵人孔等。人孔蓋通常由灰色鑄鐵,延性鐵,鑄鋼,滾動鋼,聚合物等製成。封面的中心都帶有諸如“供水供應”,“污水”,“雨水”,“雨水”或“火力”的標記。
