Abstract

The utility model discloses a bailing device applicable to an oil well. The bailing device comprises an inner pipe, wherein a sleeve is arranged at the lower end of the inner pipe; an upper baffle ring and a lower baffle ring are arranged at the two ends of the sleeve; a clamping head is arranged at the upper end of the inner pipe; a neck is formed at the lower end of the clamping head; an annular inner groove is formed in the inner pipe; an annular support seat is arranged at the bottom end of the inner groove; a spring pressing cap is arranged on the support seat; a support block is connected to the upper end of the spring pressing cap; a sliding plate is arranged in the support block; the sliding plate is connected with an inner groove wall; a liquid inlet is further formed on the inner groove wall; a pressure release joint is arranged at the lower end of the clamping head; a through groove end is formed at the lower end of the pressure release joint; a pressure release ball is arranged at the through groove end; an operating hole is further formed on the inner pipe. The bailing device applicable to the oil well disclosed by the utility model is simple in structure, convenient to use, functional in pressure release and pressure compensation, is capable of preventing bailing overload in operation, and is low in putting resistance so that time for a tool to go into the well can be saved.

Description

A kind of oil well bailing device
Technical field
The utility model relates to field mining equipment, relates in particular to a kind of oil well bailing device.
Background technology
Oil field has can not blowing, again can not be with the pumping unit low production capacity oil well of oil pumping continuously, although can only get down-hole fluid, the water conservancy project tool object that can fulfil assignment by being interrupted bailing method, but efficiency is lower, each bailing oil column is lower, consumable accessory consumption is larger, instrumental function is perfect not, also has certain risk in construction, requires improvement technology more.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of oil well bailing device, reasonable in design, has decompression function, can prevent the bailing overload in operation, has improved tar productivity.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of oil well bailing device, comprise inner tube, the lower end of described inner tube is provided with sleeve, sleeve two ends are provided with upper baffle ring and lower baffle ring, there is phase dop the upper end of described inner tube, the lower end of phase dop is provided with draw-in groove, described inner tube inside is provided with annular inside groove, the bottom of described inside groove is provided with annular brace seat, described supporting seat is provided with spring pressure cap, the upper end of spring pressure cap is connected with tray, in described tray, be provided with sliding panel, described sliding panel is connected with internal groove side wall, on described internal groove side wall, be also provided with inlet opening.
As preferably, the lower end of described phase dop is provided with relief fittings, and the lower end of described relief fittings is provided with groove end, and described groove end is provided with pressure release ball.
As preferably, in described inner tube, be also provided with handle hole, described handle hole is provided with stop screw.
As preferably, described lower baffle ring is provided with field joint, and described field joint is provided with screw thread.
The beneficial effects of the utility model are:
Adopt a kind of oil well bailing device of the utility model, simple in structure, easy to use, there is decompression function, can prevent the bailing overload in operation, there is pressure compensation, transfer resistance little, saving instrument enters the well time.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of oil well of the utility model bailing device.
Mark in figure: 1-inner tube, 2-sleeve, 3-upper baffle ring, 4-lower baffle ring, 5-phase dop, 6-draw-in groove, 7-inside groove, 8-supporting seat, 9-spring pressure cap, 10-tray, 11-sliding panel, 12-inlet opening, 13-relief fittings, the saturating groove end of 14-, 15-pressure release ball, 16-handle hole, 17-stop screw, 18-field joint.
Detailed description of the invention
As shown in Figure 1, a kind of oil well bailing device, comprise inner tube 1, the lower end of described inner tube 1 is provided with sleeve 2, sleeve 2 two ends are provided with upper baffle ring 3 and lower baffle ring 4, there is phase dop 5 upper end of described inner tube 1, the lower end of phase dop 5 is provided with draw-in groove 6, described inner tube 1 inside is provided with annular inside groove 7, the bottom of described inside groove 7 is provided with annular brace seat 8, described supporting seat 8 is provided with spring pressure cap 9, the upper end of spring pressure cap 9 is connected with tray 10, in described tray 10, be provided with sliding panel 11, described sliding panel 11 is connected with internal groove side wall, on described internal groove side wall, be also provided with inlet opening 12, the lower end of described phase dop 5 is provided with relief fittings 13, the lower end of described relief fittings 13 is provided with groove end 14, described groove end 14 is provided with pressure release ball 15, in described inner tube 1, be also provided with handle hole 16, described handle hole 16 is provided with stop screw 17, described lower baffle ring is provided with field joint 18, described field joint is provided with screw thread, when use, can carry out spacing to this device by stop screw 17, while entering well, sleeve 2 is in inner tube upper end, enter after pasta, fluid enters at inlet opening 12, in the time being lowered to oil column height and reaching requirement, go up bailing oil, water conservancy project tool, it is limited that at this moment sleeve 2 comes downwards to lower baffle ring 4 tops, because the elastic pressing cap 9 in internal construction has elastic buffer, it is relatively constant that frictional resistance keeps, oil column constantly rises to well head with instrument, realizes bailing object, when OIH post is collected complete laggard row bailing again.
Above-described the utility model embodiment, does not form the restriction to the utility model protection domain.Any amendment of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present utility model.
