Technical field
The utility model relates to a kind of wellhead equipment being applied in oil extraction in oil field field.
Background technology
It is the normal work to do of current shaft mouth operation that oil well paraffinication and scale removal are processed.Wherein oil well paraffinication generally has following rule: heavy oil wells is more serious than thin oil well wax deposition; The well wax deposition yield poorly, wellhead temperature being low is serious, and well water wax deposition lower than 2% time is serious, and moisture to exceed 60% wax deposition not serious; Tube inner wall is coarse, is not easy wax deposition; Working system changes, and the wax deposition degree of depth also can change; While dwindling oil nozzle, on wax deposition point, move, while beaming up, wax deposition point moves down.Because the situation of wax deposition is not identical, on oil field, have at present a variety ofly at the paraffin removal equipment of use, there are electrical heating paraffin removal, electromagnetism paraffin removal and insulation paraffin removal.But, because the situation of oil well can often change, cause these paraffin removal equipment to have to often be changed at well head, each replacing all can cause the waste of time and manpower, affects the production efficiency of oil well.
Summary of the invention
In order to solve the technical problem of mentioning in background technology, the utility model provides a kind of oil well paraffin prevention viscosity-falling unit, this kind of anti-wax viscosity reduction apparatus only needs once mounting at well head, just can be set to according to the needs of different oil wells hot water circuit insulation, electromagnetism paraffin removal state, versatility is stronger, and, through once adjusting Inside coil after dismounting, can change electrical heating de-waxing apparatus into, there is the effect of one-object-many-purposes.
The technical solution of the utility model is: this kind of oil well paraffin prevention viscosity-falling unit, comprise the well head header with top connection and lower contact, its unique distinction is: described device also comprises a urceolus, the upper/lower terminal of urceolus is the identical upper connection mouth of pipe and the lower connection mouth of pipe of undergauge connecting external diameter respectively, the upper connection mouth of pipe and the lower connection mouth of pipe pass through bolt-locking with well head header respectively, and on well head header and the corresponding position of the upper connection mouth of pipe and the lower connection mouth of pipe has the screwed hole passing through for described bolt; There is an annular shoulder connecting as one with described well head header at 2/3rds places in the well head header part that is positioned at urceolus, on the inwall of urceolus, be connected with an annular gear edge corresponding to described annular shoulder position integrated, annular gear along and annular shoulder between form a torus gap; Have respectively at the upper and lower end face place of urceolus and can, by the circulating hot water entrance of valve gauge tap and circulating hot water outlet, have some liquid circulation via holes on annular gear edge, in described liquid circulation via hole, the two-way valve of on off state can be manually adjusted in installation.
Described device also comprises a columnar coil winding skeleton, the internal diameter of coil winding skeleton is greater than the external diameter of well head header, the upper end of coil winding skeleton is plugged in the cannelure that urceolus upper surface inwall opens, the lower end of coil winding skeleton is plugged in the torus gap forming between annular gear edge and annular shoulder after sealing ring sealing, the outer coil being wound around by wire coiling of coil winding skeleton; Two lead wiring terminal through insulation, encapsulation process are drawn in the upper surface that passes urceolus.
The utlity model has following beneficial effect: in the time of oil well is high in the content of wax, viscosity is high, moisture rank is low or time between well-flushings is short and strata pressure is on the low side situation, by wiring terminal, the coil in device is accessed in outside alternating current loop, in header, can generate an electromagnetic field, cutting magnetic line in the time having crude oil flow in pipe, the brilliant surfactant of wax in crude oil becomes polar surfaces, be unfavorable for the further deposition of wax molecule, cannot form netted, thereby play the object of wax-proof viscosity reducing.When oil well is during in thin oil well state or low yield state, stop using electromagnetism paraffin removal, and open annular gear along upper two-way valve, by circulating hot water entrance and the hot recirculated water of circulating hot water outlet access, can realize by water circulation and be incubated and increase temperature in pipe, realize the object that reduces wax deposition.This kind of anti-wax viscosity reduction apparatus has versatility, only need to purchase a kind of equipment is arranged on well head, just can be set to according to the needs of different oil wells hot water circuit insulation, electromagnetism paraffin removal or adjust Inside coil after once dismantling, change electrical heating de-waxing apparatus into, there is the effect of one-object-many-purposes, can save the acquisition expenses of equipment and realize switching fast.
