Abstract
The invention discloses a kind of hydraulic pressure auto Isolator Well Head of good sealing effect, comprise: body, the cavity cooperatively interacted with oil pipe is provided with in described body, the lower end of body is provided with adpting flange, wire-carrying flange is connected with at the threaded upper ends of described body, the middle part of described body is provided with oil-in, in the inside of described body, upper skeleton and lower skeleton are provided with seal, described seal is arranged between upper skeleton and lower skeleton, at described upper skeleton be respectively arranged with the first sealing ring between lower skeleton and body, the second sealing ring is provided with between described wire-carrying flange lower end and the upper end of body.Advantage is: good sealing effect, and put in process at oil pipe and do not protect envelope, operating efficiency is high, and structure is simple, safe and reliable, ensures the job safety of high-pressure well.
Description
Technical field
The present invention relates to a kind of drilling equipment, particularly relate to a kind of hydraulic pressure auto Isolator Well Head.
Background technology
In oil drilling exploitation is produced, there will be a lot of high pressure wells and high pressure oil wells, because down-hole Operating Pressure has more risk, require higher to the sealing performance of equipment and personnel's construction safety.At present, put in process at oil pipe and guarantor's envelope is carried out to well head, affect operating efficiency.
Summary of the invention
Technical problem to be solved by this invention is: the hydraulic pressure auto Isolator Well Head providing a kind of good sealing effect.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: hydraulic pressure auto Isolator Well Head, comprise: body, the cavity cooperatively interacted with oil pipe is provided with in described body, the lower end of body is provided with adpting flange, wire-carrying flange is connected with at the threaded upper ends of described body, the middle part of described body is provided with oil-in, in the inside of described body, upper skeleton and lower skeleton are provided with seal, described seal is arranged between upper skeleton and lower skeleton, at described upper skeleton be respectively arranged with the first sealing ring between lower skeleton and body, the second sealing ring is provided with between described wire-carrying flange lower end and the upper end of body.
Advantage of the present invention is: above-mentioned hydraulic pressure auto Isolator Well Head, good sealing effect, and put in process at oil pipe and do not protect envelope, operating efficiency is high, and structure is simple, safe and reliable, ensures the job safety of high-pressure well.
