casing head

基本解釋

Through several year's research, a new type of casing head in view of the problems encountered in preceding stress cementing in thermal production well.
針對(duì)稠油熱采井預(yù)應(yīng)力固井中存在的問題，研制了一種適用于稠油熱采井預(yù)應(yīng)力固井的新型套管頭。
The liquid hydrocarbon recovered from casing head gas by adsorption, compression, or refrigeration. Casing head gas is the gas recovered at the surface from an oil well.
通過吸附作用、壓縮作用或冷卻作用，從套管頭氣回收到的液態(tài)烴，為一種汽油。套管頭氣是從地面上的一口油井所采到的氣體。

This article presented the research on matching technology of casing head and gas-producing wellhead for guaranteeing the safety of drilling and production test operation.
由于套管頭和采氣井口油管頭牽涉到鉆井和試油作業(yè)中的井口組合，為保證鉆井和試油作業(yè)時(shí)配套使用的安全，要進(jìn)行配套技術(shù)研究。

And so all you're left with is the little casing head, and usually a water collection tank at the top.
