Abstract
The utility model discloses an online sucker rod paraffin scraper of light maintenance operation has solved the sucker rod and has scraped the problem that wax needs manual operation and influences the environment. It is concrete including base, top cap, spring and paraffin scraper, the base bolt fastening on the cross flange of well head, base top bolted connection top cap, open in top cap and base axle center has sucker rod centralizer and festival hoop to pass the hole, the up end symmetry of base sets up two fixed ears, the paraffin scraper divide into controls two lamellas, and every lamella paraffin scraper articulates on fixed ear, and for ring cover portion, the below is slope portion above every lamella paraffin scraper, and the paraffin scraper overcoat has the spring, controls the paraffin scraper and passes through this spring staple bolt on the sucker rod to closing the back. The sucker rod shifts up, and the wax of paraffin scraper on with the pole is scraped and the pit shaft is advanced on the top, reaches and scrapes the wax purpose. Meet centralizer or when hoop festival on the pole, under the guide of paraffin scraper slope portion, the spring can be strutted by force to make centralizer and festival hoop pass through smoothly.
Description
Technical field
The utility model relates to the online paraffin removal tool of a kind of sucker rod used when field of oil field oil extraction carries out down-hole light maintenance job execution.
Background technology
All can have the long closing well of part, screw pump stem dropout well etc. when down-hole light maintenance operation every year, this part well is because the closed-in time is long, and cause a large amount of wax to condense in the wellbore, there will be severe whole pit shaft is most blocked, and cannot form well-flushing passage at all.Sucker rod can only be played by force during operation, at this moment whole sucker rod can overwork wax post, the wax post be attached on sucker rod can only scrape and fall to the ground by workman by hand, reclaim afterwards, the result done like this, on the one hand regenerant impurity is many, is made dirty on the other hand, have a strong impact on environment around well head by the sump oil, the sewage that land.
Summary of the invention
The purpose of this utility model is to provide the online rod scraper of a kind of light maintenance operation, the wax on sucker rod can be scraped and chip away and jacking pit shaft, do not need artificial scraping, also protect environment in the process that this paraffin scraper trips out at sucker rod.
For achieving the above object, the technical solution adopted in the utility model is: the online rod scraper of a kind of light maintenance operation, comprise pedestal, top cover, spring and paraffin scraper, described pedestal has upper and lower two horizontal end faces, lower level-end face is bolted to connection on the four-way flange of well head, upper level-end face bolt connects top cover, and top cover and pedestal axle center have oil pumping rod centering device and joint binds round through hole, and the upper surface of pedestal is also symmetrical arranged two fixing ears; Described paraffin scraper is divided into left and right two lobes, be ring sleeve portion above every lobe paraffin scraper, below is ramp, ramp is provided with connecting rod to downward-extension, connecting rod is by bolted splice on fixing ear, and ring sleeve portion and ramp joint arrange caulking groove, and left and right caulking groove is combined to form a cannelure, cannelure inner sleeve has spring, passes through this spring anchor ear after left and right paraffin scraper is involutory on sucker rod.
The beneficial effects of the utility model: use the application's paraffin scraper, when playing sucker rod operation, first paraffin scraper pedestal is arranged on well head four-way flange, sucker rod passes through from paraffin scraper center, under the action of the spring, two lobe paraffin cutting half hold sucker rod tightly, all the time along with sucker rod moves up, wax on sucker rod is scraped and is chipped away and jacking pit shaft by paraffin scraper, reaches paraffin cutting object.Again because paraffin scraper have employed the ramp structure with guiding function, adopt the spring mode of holding tightly simultaneously, when sucker rod go upward to external diameter become large centralizer or joint hoop time, spring can be strutted by force, thus centralizer and joint hoop are passed through smoothly.
Accompanying drawing explanation
Fig. 1 is the structural representation of the online rod scraper of light maintenance operation.
Fig. 2 is that centralizer is by view during paraffin scraper.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
Shown in Fig. 1 composition graphs 2: the online rod scraper of a kind of light maintenance operation, comprise pedestal 6, top cover 2, spring 3 and paraffin scraper 4, described pedestal 6 has upper and lower two horizontal end faces, lower level-end face is bolted to connection on the four-way flange of well head, upper level-end face bolt connects top cover 2, top cover 2 and pedestal 6 axle center have oil pumping rod centering device and joint hoop 5 passes hole, and the upper surface of pedestal 6 is also symmetrical arranged two fixing ears; Described paraffin scraper 4 is divided into left and right two lobes, be ring sleeve portion 41 above every lobe paraffin scraper, below is ramp 42, ramp 42 is provided with connecting rod to downward-extension, connecting rod is by bolted splice on fixing ear, and ring sleeve portion 41 and ramp 42 joint arrange caulking groove, and left and right caulking groove is combined to form a cannelure, cannelure inner sleeve has spring 3, passes through this spring 3 anchor ear after left and right paraffin scraper is involutory on sucker rod 1.
