Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0016] Such as figure 1 As shown, the first embodiment of the continuous two-way lifting oil well pump of the present invention includes an inner cavity 1 and an outer cavity 2, and the inner cavity is arranged inside the outer cavity, so that the oil well pump forms the inner space A1 of the inner cavity 1 and the inner cavity and the outer cavity The interlayer space A2 between, the top of the outer cavity 2 is connected with the oil pipe;

[0017] There is a top seal on the top of the inner chamber, and a piston 4 is arranged in the inner chamber 1. The piston 4 divides the inner space A1 into two parts, the upper space and the lower space. The sucker rod 9 passes through the top seal and connects with the piston 4. The sucker rod 9 seal with the top seal;

[0018] The bottom of the inner cavity and the outer cavity is provided with an end ...

Abstract

The invention discloses a continuous bidirectional-lifting oil well pump. The oil well pump comprises an inner cavity and an outer cavity, wherein an interlayer space located between the inner cavity and an outer cavity is formed in the inner space of the inner cavity; a top seal is arranged at the top of the inner cavity, a piston which divides the inner space into an upper space and a lower space is arranged in the inner cavity, and an oil pumping rod penetrates through the top seal and is connected with the piston; and end cover is arranged at the bottoms of the inner cavity and the outer cavity and is provided with a lower pump body oil inlet valve leading to the lower space, a lower pump body oil outlet valve leading to the interlayer space is arranged at the lower part of the side wall of the inner cavity, an upper pump body oil outlet valve leading to the interlayer space is arranged at the upper part of the side wall of the inner cavity, and an upper pump body oil inlet valve leading to the upper space is arranged at the upper part of the side wall of the outer cavity; and the lower pump body oil inlet valve, the lower pump body oil outlet valve, the upper pump body oil outlet valve and the upper pump body oil inlet valve are one-way valves. According to the continuous bidirectional-lifting oil well pump, oil can be pumped in an upstroke and a downstroke, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of petroleum mechanical exploitation, in particular to an oil pump used for oil recovery in an oil field. Background technique [0002] The oil well pump is used in the petroleum industry and is a kind of mechanical equipment that lifts petroleum from the ground to the surface, accounting for more than 90% of the total mechanical oil recovery. The mechanical conventional plunger reciprocating oil production pump currently used in the oil field can only pump oil through mechanical action such as the sucker rod on the ground, but the up and down strokes of the oil pumping are intermittent one-way lifting and oil discharge, which cannot realize continuous pumping during the reciprocating operation of the piston. Lifting out oil, the efficiency of surface machinery and underground oil well pump is lower than 50%, resulting in energy waste. Contents of the invention [0003] The technical problem to be solved ...
