Abstract

The utility model relates to a horizontal fixed valve used for a down-hole pump in the oil industry. The utility model has the technical scheme that the horizontal fixed valve mainly comprises a body, a valve seat and a valve, wherein the valve seat, the valve and a track are arranged in an inner cavity of the body, and the valve is mounted in the track, and the valve seat is mounted below the valve; magnetic steel is mounted in the valve seat, and the valve horizontally moves along the track and moves to be sealed by liquid force and the magnetic force of the magnetic steel in resetting. The utility model has the advantages that the down-hole pump can be mounted in any position of a well with the designed depth because the valve can horizontally move along the track. The utility model is particularly suitable for a hydraulic pump in rodless pumps, can obviously reduce the production cost, can increase the yield of crude oil, and can improve the whole benefits of crude oil development.

Description

The horizontal fixed valve

One, technical field:

The utility model relates to a kind of exploitation corollary apparatus of petroleum industry, the horizontal fixed valve that particularly a kind of oil field down-hole pump is used.

Two, background technology:

Existing oil field down-hole pump standing valve mainly is made of valve, valve seat, and valve can only be in movement in vertical direction, by the gravity sealing of valve.Progress along with present drilling technology, in the Development and Production of big gradient oil well and horizontal well, owing to above standing valve can only can only be installed in down-hole pump more than the inclination section in the reason of movement in vertical direction, have a strong impact on oil well output, reduce the overall efficiency of oil extraction.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of horizontal fixed valve that can move in the track of design rule is provided, and down-hole pump can be installed to any position of design well depth.

Its technical scheme is: mainly be made up of body, valve seat and valve, chamber body is provided with valve seat and valve, chamber body is equipped with track, dress valve in the track, valve is the dress valve seat down, dress magnet steel in the valve seat, and described valve moves along track cross level, when resetting, by the magnetic force and the sealing of fluid power and magnet steel.

Wherein, the track inner chamber is provided with a plurality of orbital planes and a plurality of flow channel for liquids, and orbital plane supports the valve orbital motion.

The beneficial effects of the utility model are: because valve can carry out horizontal movement along track, so down-hole pump can be installed to any position of design well depth, be specially adapted to the hydraulic pump in the rodless pump, it can obviously reduce producing cost, increase crude output, improve the overall efficiency of oil extraction.

Four, description of drawings:

Accompanying drawing 1 is a sectional view of the present utility model;

Accompanying drawing 2 is A-A sectional views of the present utility model.

Five, the specific embodiment:

In conjunction with the accompanying

drawings

1 and 2, the utility model will be further described: its technical scheme is: mainly be made up of body 1, valve seat 3 and valve 4, chamber body is provided with valve seat and valve, body 1 inner chamber is equipped with track 2, dress valve 4 in the track, and valve is dress valve seat 3 down, dress magnet steel 5 in the valve seat 3, described valve moves along track cross level, when resetting, by the magnetic force and the sealing of fluid power and magnet steel 5.

Wherein, described track 2 inner chambers are provided with a plurality of orbital planes 6 and a plurality of flow channel for liquids 7, are illustrated in figure 2 as four orbital planes and four flow channel for liquids are formed at interval, and wherein, orbital plane supports valve 4 orbital motions.

The utility model is installed in below the pump, and when down-hole pump aspirated, valve left valve seat, but can only move in the track of rule.When valve resets, under the double acting of fluid power and magnetic force, reset and seal along track.Oil recovery is adopted the utility model with down-hole pump, down-hole pump can be installed to any position of design well depth, is specially adapted to the hydraulic pump in the rodless pump.It can obviously reduce producing cost, increases crude output, improves the overall efficiency of oil extraction.
