Description
Technical field
The utility model relates to the blowout control device of petroleum industry actuating oil-pumping unit, especially a kind of sucker rod hanging combination is robbed
Spray apparatus can occur to rob dress in time when overflow during actuating oil-pumping unit, prevent gas blowout accident.
Background technique
Oil well insert pump actuating oil-pumping unit in operation process is important flow chart, takes out when in actuating oil-pumping unit or well
When beam hanger column lower part is with eccentric abrasion prevention device, centralizer or major diameter tool, because tool diameter is greater than wellhead flange minimum diameter,
It can just be removed after well up flange must be unloaded.The well especially having needs to install blowout preventer because of rod parting, after playing oil pipe
Recur sucker rod.When overflow occurs for actuating oil-pumping unit after being mounted with blowout preventer, at present generally using rod connector and oil pumping
It after bar connection, is sitting in above well mouth hanger, lays down lift portion and close blowout preventer；Alternatively directly sucker rod is thrown away
Enter in well, closes blowout preventer.First method is because rod connector can not be connect with well mouth hanger, when borehole pressure is larger
When, sucker rod can be sprayed ground in the short time and caused the accident.Sucker rod is directly thrown away the way in well, wink by another kind
Between gravity be easy to pounding well oil pipe into tripping, bring is the fishing that increasingly complex and bigger cost is paid.
Summary of the invention
The purpose of this utility model provides a kind of sucker rod hanging combination and robs aiming at the deficiencies in the prior art
Spray apparatus can quickly be connect with underground sucker rod and well mouth hanger, prevent the generation of gas blowout accident, protect environment, be reduced
Production cost.
The technical solution of the utility model is: a kind of sucker rod hanging combination blowout control device includes blowout hookup, blowout prevention dress
It sets and is connect by tubing coupling and connecting short section with sucker rod hanging connector；Sucker rod hanging connector be equipped with sucker rod connecting pin and
Blowout hookup connecting pin is hung at least provided with a well head on the ontology between blowout hookup connecting pin and sucker rod connecting pin
Device linkage section.
Compared with prior art, the remarkable result of the utility model is: during actuating oil-pumping unit, when generation overflow
Or when blowout, quickly the present apparatus can be connect with sucker rod in well, at well mouth hanger, be hung using suitable well head
Device linkage section and well mouth hanger screw thread prevent sucker rod from spraying ground to button is connected.Since during robbing spray, this is practical new
The sucker rod hanging connector of type, which connect with well mouth hanger, reuses half envelope blowout preventer is in clamping connection pipe nipple, utilizes cock
Valve controls well head overflow, when overflow occurring in well or when blowout, can quick closing well, effectively prevent the generation of gas blowout accident.This
Tool is easy to use, securely and reliably, can effectively prevent the generation of gas blowout accident, avoid sucker rod throw away well without resistance to selection.
It significantly reduces worker's labor intensity and reduces production cost, protect environment, there is good using effect.
