Abstract
The utility model discloses a cleaner for a water well of an oil field, comprising a connecting shaft, a bearing seat, a main body, a connecting sleeve, a cone and a choke plug which are all sequentially connected. The utility model is characterized in that a helical wiper-blade groove and a pollution discharge groove are arranged on the main body and the cone, a wiper-blade and a spring which is positioned under the wiper-blade are fixed in the wiper-blade groove, and a water outlet is arranged in the pollution discharge groove. The utility model has the advantages of simple structure, convenient usage and perfect effect of scale removal.
Description
One, technical field: the utility model relates to a kind of oil field downhole tool, particularly a kind of oil field well descaler.
Two, background technology: at present; the oil field well is after using certain hour; the phenomenon that fouling usually can occur; cause tester and power tool can not descend underground work,, can only stop to produce and clear up owing to there is not special apparatus for eliminating sludge; time needs one or two months; so not only delay manufacturing schedule, and increased running cost greatly, caused very big economic loss.
Three, summary of the invention: the purpose of this utility model just is to provide a kind of can remove the device of fouling fast---oil field well descaler.Technical solution of the present utility model is: described descaler mainly is formed by connecting in turn by connecting axle, bearing support, main body, adapter sleeve, cone and plug, on main body and cone, offer spiral helicine film trap and the dirt discharge groove scraped, in scraping film trap, be fixed with scraping blade and place spring below the scraping blade, in dirt discharge groove, offer weep hole; Offer sewage draining exit on plug, scrape film trap and dirt discharge groove on main body and the cone are and distribute alternately.The utility model is simple in structure, and modern design is easy to use, and scale removal is quick, effective, only needs to finish in one hour, and that can guarantee to produce normally carries out, and greatly reduces maintenance cost, has avoided unnecessary economic loss.
Four, description of drawings: Fig. 1 is a main TV structure schematic diagram of the present utility model;
Fig. 2 is A among Fig. 1-A generalized section.
Five, the specific embodiment: described descaler is mainly by connecting axle 1, bearing support 2, main body 3, adapter sleeve 4, cone 5 and plug 6 are formed by connecting in turn, bearing 13 is housed in bearing support 2, bearing support 2, main body 3, adapter sleeve 4,6 of cone 5 and plugs all adopt and are threaded and install jackscrew additional, offer sewage draining exit 12 on the plug 6, the effect of plug 6 is to reduce resistance, help penetrating layer of scale, what offer respectively on main body 3 that shape in the shape of a spiral distributes scrapes film trap 7 and dirt discharge groove 8 each three, what offer also on the cone 5 that shape in the shape of a spiral distributes scrapes film trap 7 and dirt discharge groove 8 each three, and scrape film trap 7 and dirt discharge groove 8 on main body 3 and the cone 5 are and distribute alternately.In scraping film trap 7, be fixed with scraping blade 9 and place spring 10 below the scraping blade 9, in dirt discharge groove 8, offer two weep holes 11.Scraping blade 9 mainly works to scrape dirt, and the effect of dirt discharge groove 8 and weep hole 11 is to impact dirt and the discharge that scraping blade scrapes.The upper end of connecting axle 1 is processed with screw thread, be used for being connected with the instrument or the instrument on top, the utility model in use, need be connected down the lower end of the tester or the power tool of down-hole, running into the tube wall incrustation place is automatic desludging, production is normally carried out, avoided the economic loss of bringing because of shut-down.
