Background technology
At present, in the oil field development intermediary and later stages,, owing to higher salt content is arranged and have hydrogen sulfide in the well liquid, the corrosion of sleeve pipe is aggravated day by day simultaneously because well liquid water content increases year by year and the continuous of well wellbore sleeve pipe wears out.These ferromagnetic materials are with from the fine sand coagulation on stratum together, form a kind of in well liquid the black oil-sand of free settling not.Restart in pressure break or the like oil well operation process and after termination of pumping a period of time when perhaps certain reason causes oil well liquid level unstable, the entering oil well pump that this oil-sand will comparatively be concentrated not only causes the holddown accident, and can aggravate the wearing and tearing of oil well pump.Chinese patent ZL99208178.5 discloses a kind of oil well with magnetic filter sand device, is a kind of pump installation that protects that is installed under the oil well pump, can adsorb the oil-sand coagulum effectively; Stop it to get into the pump housing, the wearing and tearing that alleviate pump prolong pump detection period; Prevent the holddown accident, thereby protect oil well pump effectively.
The utility model content
The purpose of the utility model is: antirust down-hole string of a kind of rod-pumped well and roofbolt are provided, utilize the magnetic sand filter, stop sand to get in the oil well pump, the wearing and tearing that alleviate pump solve the part well wellbore because iron rust causes the problem of holddown.
The technical scheme that the utility model adopts is: antirust down-hole string of rod-pumped well and roofbolt, comprise down-hole string and down-hole rod string, and down-hole string and down-hole rod string are lowered in the oil well, it is characterized in that:
Down-hole string mainly is made up of with magnetic sand filter, last tail pipe, standing valve, plunger displacement pump and oil pipe plug, time tail pipe, screen casing, middle tail pipe, oil well.The upper end of plug connects tail pipe down, and the upper end of following tail pipe connects screen casing, tail pipe during the upper end of screen casing connects; The upper end of middle tail pipe connects oil well and uses the magnetic sand filter; Oil well connects upward tail pipe with the upper end of magnetic sand filter, and the upper end of last tail pipe connects standing valve, and the upper end of standing valve connects plunger displacement pump; The upper end of plunger displacement pump connects oil pipe, and oil pipe is connected to well head.
The down-hole sucker rod mainly is made up of last sucker rod, middle sucker rod and lower sucker rod, and oil pump plunger piston is arranged in plunger displacement pump, and the lower end of lower sucker rod is connected the upper end of oil pump plunger piston; Sucker rod during the upper end of lower sucker rod connects; The upper end of middle sucker rod connects goes up sucker rod; Last sucker rod is connected to well head.
The external diameter of the plug in antirust down-hole string of rod-pumped well and the roofbolt is 88.9mm; The external diameter of following tail pipe, middle tail pipe, screen casing and last tail pipe is 73mm; Oil well uses the external diameter of magnetic sand filter to be 114mm, and the external diameter of plunger displacement pump is 32～56mm, and the external diameter of oil pipe is 73mm.Oil well is produced by the sharp moral magnetizer of North China oil factory with the magnetic sand filter.
The beneficial effect of the utility model: antirust down-hole string of the utility model rod-pumped well and roofbolt, utilize magnetic sand filter absorption shaft bottom magnetic bits, the wearing and tearing that can alleviate pump prolong the pump detection period twice; And can prevent that the holddown accident from taking place.
