Description
Technical field
This utility model relates to a kind of offshore oil production equipment, particularly to a kind of offshore oil production scraping scale prevention device.
Background technology
Oil field is for a long time during oil, owing to stratum oil complexity causes oil pick-up tube and the fouling of sucker rod, wax deposition, corrosion, badly influence oil recovery efficiency, the way the most always continuing to use aqueous chemical auxiliary agent solves the fouling of oil well, wax deposition, the problem of corrosion, this way difficulty of construction is big, and manpower and materials consume many, largely add cost for oil production, therefore, many unfavorable factors are brought to oil field production.
China application publication number CN 103132950 A, Patent No. 201110381301.X, disclose a kind of oil well paraffin prevention scale prevention device, central canal, by screw thread jointing and pipe box cupling respectively, is provided with core pipe, is cased with wax-proof anti-scaling chemical block core on core pipe in central canal, fastening lid and pallet it is respectively arranged with at core pipe two ends, realize wax control scale removal by wax-proof anti-scaling chemical block core, the pollution of crude oil during scale removal, can be caused, affect the effect of extraction oil.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, it is provided that a kind of offshore oil production scraping scale prevention device, has simple in construction, it is easy to operation, the feature that wax removal is effective, greatly reduces hand labor intensity simultaneously.
Its technical scheme is: include top connection, lower contact, central canal, antiscale scraper, rotate righting head, connected by central canal between top connection and lower contact, antiscale scraper is fixed by rotating righting head in the inside of described central canal, described antiscale scraper includes scraping shell, coil tension spring, taper protective head, scraping blade, valve rod, fixed cover, the top of scraping shell connects valve rod by fixed cover, the bottom of scraping shell connects taper protective head, the inside of described scraping shell is provided with coil tension spring, one end of described coil tension spring is connected to the bottom of scraping shell, the other end of coil tension spring connects fixed cover, the outer wall of described scraping shell is provided with scraping blade.
Above-mentioned scraping blade is tapered blade, improves the effect of scraping scale removal.
The beneficial effects of the utility model are: have simple in construction, easily operated, the feature that wax removal is effective, greatly reduce hand labor intensity simultaneously, the scale problems within central canal can effectively be removed by antiscale scraper, realizing effectively removing wax dirt, coil tension spring drives scraping shell to move up and down the effective scale removal realized center inside pipe wall.
