Description
Technical field
The utility model belongs to the device of oil well, is a kind of wellhead assembly preventing grease aerial drainage to ground, tool
Body is a kind of well head drainage blowdown apparatus.
Background technology
Well oil pipe is gone out from well and is put to ground in workover treatment by oil field.It is unable to draining in downhole oil tubing string
When（Bleeder or bleeder are not installed and cannot be opened in tubing string lower part）, rise on wellhead assembly oil pipe with its under
After coupler detaching, rises to come out from dismounting place aerial drainage to the grease in the oil pipe on wellhead assembly, be sprayed onto around well head
With operating worker, cause wellhead assembly and operation field by oily wastewater pollution, one side operating worker can be sprayed shallow by grease, make
Health is severely damaged, is not easy to job execution, on the other hand also creates pollution environment.
Invention content
The purpose of this utility model is a kind of well head drainage blowdown apparatus of design, and when bringing it about the above problem, fluid can
To flow to specified position, overcome the problems, such as above-mentioned, avoids causing operating worker from spraying shallow and wellhead assembly, operation by grease
Scene is by oily wastewater pollution.
What the purpose of this utility model was realized in：Including supporting rod, collecting bag, support snap-gauge, upper oil pipe, cover board,
Box cupling, pipe elevator, blow-off pipe, lower oil pipe, blowout preventer, upper oil pipe, box cupling, lower oil pipe are sequentially connected across blowout preventer, oil pipe
Elevator blocks box cupling, and the weight of oil pipe, box cupling, lower oil pipe is made to be transferred on blowout preventer, upper oil pipe easy to disassemble and box cupling it
Between connection screw thread, support snap-gauge is semicircle ring structure, two pieces of support card boards at the undergauge on blowout preventer top after two pieces of branch
Support snap-gauge links into an integrated entity into disc, keeps support snap-gauge stiff, several supporting rods is installed on support snap-gauge, several
Collecting bag is placed in the space that supporting rod surrounds, and sewage draining exit is opened up on the inner wall of collecting bag, blowdown is installed outside the sewage draining exit
Cover board is installed in the upper end of pipe, supporting rod, and cover board is semicircle ring structure, is disc after two cover plates semicircular ring folding structures, receives
Collection bag be made of flexible material, collecting bag cover the lower part of oil pipe, box cupling, lower oil pipe top, dismantle the lower part of oil pipe
After the connection screw thread of box cupling, the fluid in upper oil pipe is flowed out through the sewage draining exit to be connect away by blow-off pipe.
The utility model has the beneficial effects that：The utility model has found supporting point on blowout preventer, enables all parts
It is installed on operation wellhead, after dismantling the lower part of oil pipe and the connection screw thread of box cupling, the fluid in upper oil pipe is through the row
The outflow of dirty mouth is connect away by blow-off pipe, and therefore, the utility model can reach purpose of design, overcome presently, there are the problem of, can be with
It avoids that operating worker is caused to spray shallow and wellhead assembly, operation field by oily wastewater pollution by grease.
Description of the drawings
Fig. 1 is the installation diagram of the utility model.
Specific implementation mode
