Abstract
The utility model discloses a deep well oil pump with a sealing ring and belongs to a tubular pump for the crude oil pumping in a well. At present, the deep well oil pump of each oil field in the well is primarily the tubular pump. Because the crude oil in the well contains the corrosion mass and sand, the life of the pump is shortened. In order to enhance the life of the deep well oil pump, the deep well oil pump with a sealing ring composed of a piston with the sealing ring and a pump working barrel is provided. The use method of the deep well oil pump with a sealing ring is the same as the use method of the tubular deep well oil pump. The deep well oil pump with a sealing ring is also applicable to each oil field. The utility model has the advantages of the long service life, the simple manufacturing technique, a short pump body, the economization of the steel, the convenient maintenance, etc.
Description
The utility model belongs to the tubing pump of down-hole oil extraction.
Existing tubing pump is made up of the pump work tube and the piston of belt material cover, the long 2.5-3.3 rice of pump, long 1.0 meters of piston.Owing to contain corrosion matter and sand in the crude oil of down-hole, to very big influence is arranged in application life of deep well oil pumping.
In order to prolong the application life of pump, make and existing scrap deep well oil pumping and can be fully utilized, the utility model proposes new technical scheme to deep well oil pumping.
The sealing ring type deep well oil pumping is by pump work tube (1), and lining (4) has piston (5), joint ring (2) and the O-ring seal compositions such as (3) of joint ring.The work tube length 1.5-2.0 rice of pump, piston is long to be 0.3-0.4 rice.2-6 tool joint ring at regular intervals is housed on the piston.The joint ring opening part can be " ' " type, also can be "
" type.In a groove, can place one or more joint rings.In order to leak between anti-stop ring and the groove, can in the gap, place elastic sealing ring, form all-sealed structure.The ring that is contained on the piston is dismountable, after the ring wearing and tearing, can change, and has so just prolonged application life.
The using method of sealing ring type deep well oil pumping is the same with general tubular type deep well oil pumping.When removing pump, piston can be by compressing the seating nipple of freely coming in and going out that cooperates of box cupling inclined-plane and the first lining chamfering.
The sealing ring type deep well oil pumping is compared with existing deep well oil pumping, and it is short to have a pump housing, saves steel, the manufacturing process tube just, advantages such as long service life.
