Embodiment Construction

[0010] The present invention will be further described below in conjunction with the embodiments: the chemical compound flooding and anti-scaling soft plunger oil well pump includes a pump barrel 5 and a plunger body 3, the plunger body 3 has a built-in center bracket 4, and the center bracket 4 with a long hole The inner layer 8 of the plunger body bushing, the outer layer 7 of the plunger body bushing and the sealing ring 6 are sequentially set on the outside. The sealing ring 6 is made of high hardness and wear-resistant carbon fiber nylon material, and the inner layer 7 of the plunger body bushing and the plunger The outer layer 8 of the body bushing is made of rubber material, and the plunger body 3 adopts the above-mentioned soft plunger design. Its function is to lift the liquid by relying on the pressure of the liquid column to expand and seal the pump barrel during the upstroke of the plunger body 3, and to lift the liquid during the downstroke. The shrinkage of the so...

Abstract

The invention discloses a chemical compound driving and antiscaling oil pump of soft plunger, which comprises a pump cylinder (5) and a plunger body (3). In the pump cylinder (5), the plunger body (3) is placed; in the plunger body (3), a central support (4) is placed. Out the central support (4) that is provided with a long strip-like hole, the inner layer of the liner for the plunger body (8), the outer layer of the liner for the plunger body (7), and a seal ring (6) are looped sequentially; the upper and lower end of the inner layer of the liner for the plunger body (8), the outer layer of the liner for the plunger body (7), and the seal ring (6) are provided with upper and lower lock nuts (10, 9); the central support (4) is threadedly connected with the upper and lower lock nuts (10, 9). The plunger oil pump can effectively prevent any pump blocking, prolong to the max. extent the time period between two maintenances, also improve the pump efficiency and reduce the production cost.

Description

Technical field: [0001] The invention relates to the technical field of chemical composite flooding, water flooding or polymer flooding oil production in oil fields, in particular to a chemical composite flooding anti-scaling soft plunger oil well pump. Background technique: [0002] As one of the important measures to enhance oil recovery, the chemical compound flooding technology has been applied in a larger scale year by year. At present, two lifting methods, pumping unit and screw pump, are mainly used in chemical compound flooding production wells. During the field test, the lifting equipment had a serious fouling problem, which brought serious adverse effects to the normal production of the oil well. For the plunger pump, the main manifestations are fouling on the outer surface and inner surface, increasing frictional resistance, and pump jamming in severe cases. During the peak scaling period, the average pump inspection cycle is only 10-30 days. The anti-scaling and...
