Abstract
The invention discloses a controllable pressure-type sucker rod blowout preventer. The pressure-type sucker rod blowout preventer is safe in use, and comprises a sucker rod blowout preventer body, wherein a regulating valve communicated with the interior of the sucker rod blowout preventer body is arranged outside the sucker rod blowout preventer body; a regulating handle is arranged on the regulating valve; a pressure regulating outlet and a pressure gauge are arranged on the regulating valve. The pressure-type sucker rod blowout preventer has the advantages that pressure in a well can be clearly displayed, automatic pressure release is performed under excessive pressure, and well control risks can be reduced to ensure safer well control operation, and is simple in structure and convenient to use.
Description
Technical field
The present invention relates to a kind of oil exploration equipment, especially a kind of controlled pressure type blowout preventer for sucker rod.
Background technology
In petroleum natural gas exploration, if when having pressure in well, need well head is provided with blowout preventer for sucker rod, existing blowout preventer for sucker rod can only be closed well head, can not show the pressure in well, causes too high risk to well control operation.
Summary of the invention
Problem to be solved by this invention is: the controlled pressure type blowout preventer for sucker rod providing a kind of use safety.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: controlled pressure type blowout preventer for sucker rod, comprise: blowout preventer for sucker rod body, the control valve be connected with blowout preventer for sucker rod body interior is had in described blowout preventer for sucker rod body arranged outside, described control valve is provided with regulating handle, described control valve is provided with pressure regulation outlet and pressure meter.
Advantage of the present invention is: above-mentioned controlled pressure type blowout preventer for sucker rod, can know display borehole pressure, can automatically bleed off pressure during hypertonia, can reduce well control risk, make well control operation safer, and structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the controlled pressure type blowout preventer for sucker rod of the present invention
In figure: 1, blowout preventer for sucker rod body, 2, control valve, 3, regulating handle, 4, pressure regulation outlet, 5, pressure meter.
Detailed description of the invention
Particular content of the present invention is described in detail below in conjunction with the drawings and specific embodiments.
