Abstract
The utility model relates to a self spin plunger anti-seizing oil pump used in sand generating wells and thermal production wells. The utility model is composed of a pump barrel upper joint 1, a pump barrel lower joint 12, a sucker rod joint 2, a pump barrel 3, a connecting rod 4, an upper spin joint 5, a lower spin joint 11, a sand scraping sleeve 6, a spiral body 7, a plunger 8, a traveling valve 9, a traveling valve cover 10, a standing valve 13, a standing valve cover 14 and a standing valve lower joint 15. The oil pump has the advantages of novel design and reasonable structure. The utility model which is utilized can effectively prevent a plunger from being seized by sand or glued by heat in oil wells, particularly generating sand wells and thermal production wells. Thereby, the utility model reduces the operating frequency of the oil wells, and decreases the oil production cost.
Description
The utility model relates to a kind of downhole pump that is used for sand output well, thermal production well.
Downhole pump is the visual plant that recovers the oil in the oil field.At present, the downhole pump structure of field by using is varied, and have different characteristics and function separately, but component owing to do not rotate, strike-off in its structure composition, thereby plunger do not have rotation anti-sticking function, can not adapt to the working condition of sand output well, thermal production well, the time have plunger sand card or heat seal fault to take place, make oil well operation number of times increase, the oil recovery cost of production improves.
The purpose of this utility model is to provide a kind of plunger to have rotation anti-sticking function, can effectively prevent the spinning plunger anti-sticking oil well pump that plunger sand card, heat seal fault take place.
The utility model is to realize like this.This kind oil well pump is made up of pump barrel and rotary plunger; Swivel joint and sand scraping sleeve are equipped with in the plunger upper end, and lower swivel is equipped with in the lower end, and the plunger mesopore is equipped with heliconid; Last swivel head goes out oil groove along circumferentially being evenly equipped with 3--5 left-handed spiral, and left-handed ribbon spiral body is housed in lower swivel and the plunger hole, ring sand scraping sleeve closed at both ends, and the centre has skewed slot.Because swivel joint, heliconid and sand scraping sleeve have been installed on plunger, make plunger in oil pumping process, produce at random right rotation campaign, thereby can prolong oil well pump working life, prevent the generation of sand card and heat seal fault effectively, reach and reduce oil well operation number of times, reduce the purpose of oil recovery cost of production.
The utility model modern design, rational in infrastructure, utilize it can particularly in sand output well, thermal production well, effectively prevent the generation of plunger sand card, heat seal fault, thereby reduce oil well operation number of times at pumping well, reduce cost for oil production, be suitable for and apply.
Accompanying drawing is a general structure schematic representation of the present utility model.
Below in conjunction with accompanying drawing enforcement of the present utility model is further specified.
As shown in the figure, the utility model is made up of the upper and lower joint 1,12 of pump barrel, rod connector 2, pump barrel 3, connecting rod 4, upper and lower swivel joint 5,11, sand scraping sleeve 6, heliconid 7, plunger 8, traveling valve 9, the valve bonnet 10 that moves about, standing valve 13, standing valve cover 14, standing valve lower contact 15, its structure, the assembling feature as follows: pump barrel 3 upper and lower ends are respectively by pump barrel upper connection 1 and the lower contact 12 of being threaded, the standing valve cover 14 of dress standing valve 13 in pump barrel lower contact 12 lower ends are connected to by screw thread, valve bonnet 14 is by being connected to standing valve lower contact 15 under the screw thread; Pump barrel 3 internal upper parts are provided with rod connector 2, and it is connected to connecting rod 4 with screw thread down, are set with swivel joint 5 and sand scraping sleeve 6 outside the connecting rod 4, and last swivel joint 5 lower ends are connected with plunger 8 upper ends with screw thread, and sand scraping sleeve 6 places plunger 8 upper ends; Be provided with heliconid 7 in plunger 8 mesopores, the lower end links to each other with the valve bonnet 10 that moves about by screw thread, is provided with traveling valve 9 in the valve bonnet 10, and the lower swivel 11 of heliconid 7 is housed in the lower end has with the screw thread tipping.Wherein, last swivel joint 5 is a hollow cylindrical body, and its periphery top goes out oil groove along circumferentially being evenly equipped with 3--5 left-handed spirality, and the middle part is to be attached thereto logical straight trough, lower end band outside thread.Sand scraping sleeve 6 is ring, and it is closed at both ends up and down, and the centre is evenly equipped with 12--16 skewed slot.Heliconid 7 is provided with the heliconid of left-handed structure ribbon spiral for the surface.
