Description
本实用新型涉及油田机械设备领域，具体涉及一种油田用套管头。The utility model relates to the field of oilfield mechanical equipment, in particular to a casing head for oil field.
油套管是开采石油和天然气所必须的石油专用管材，数百根油套管通过套管接头进行连接，形成长达数千米的管柱，承担开采石油和天然气的任务。油套管运送石油时，内部通常还是有部分空气，而空气中的氧气是石油燃烧的必要气体，氧气含量高低直接影响到石油运输的安全性。现有的油田用套管头无法监测内部的氧气含量，不能够给人们危险提醒，导致石油运输的安全性不够。The oil casing is the oil-specific pipe necessary for the exploitation of oil and natural gas. Hundreds of oil casings are connected through casing joints to form a column of several kilometers long, which is responsible for the exploitation of oil and natural gas. When oil casings transport oil, there is usually some air inside, and the oxygen in the air is the necessary gas for oil combustion. The high oxygen content directly affects the safety of oil transportation. Existing oilfield casing heads are unable to monitor the internal oxygen content and cannot give people a hazard warning, resulting in insufficient safety of oil transportation.
