Abstract
A sliding sleeve switch, by the top connection, sliding sleeve switch, O-ring, gas lift check valve, by-pass hole, gas lift working cylinder body, lower joint make up, the utility model discloses because of adopting the top connection to connect sequentially with sliding sleeve switch, gas lift working cylinder body lower joint, there are O-rings between sliding sleeve switch and gas lift working cylinder body, there are check valve of gas lift and by-pass hole on the gas lift working cylinder body, meet the sand and block up the need of back flushing sand in the construction of fracturing gas lift drainage; after the gas lift liquid drainage of a new well, the oil well which can not be self-blown can directly descend the rod pump to produce under the condition that the tubular column can not be moved after the gas lift working barrel is closed, so that one-time tubular column operation is reduced, the installation is convenient, and the operation is simple. The work is reliable, and the device is very suitable for field application.
Description
Technical field:
The utility model relates to the downhole tool that uses on a kind of field produces, particularly a kind of sliding sleeve switch.
Background technology:
Existing pressure break gaslift discharge opeing integrated gaslift seating nipple gas lift valve and ball-and-seat are opened under the casing pressure effect.When being used in the pressure break discharge opeing, if sand plug in the pressing crack construction, just need the anti-flushing well sand washing, if the casing pressure during the well-flushing sand washing reaches the gas lift valve opening pressure, flushing fluid will flow into oil pipe from gaslift seating nipple by-pass prot position, form circulation, and the fracturing sand in the oil pipe of gaslift seating nipple bottom can not be discharged, sand plug can not be removed, and will cause well workover, influences fracturing effect.
The utility model content:
The purpose of this utility model is to provide a kind of sliding sleeve switch, and it is connected on the gaslift seating nipple, and sliding sleeve switch passes through Ground Control, enforced opening or close the by-pass prot of gaslift seating nipple, when sliding sleeve switch closed, even gas lift valve and ball-and-seat are all opened, the oil jacket annular space can not be communicated with.When pressure break gaslift discharge opeing integrated construction, can guarantee normally carrying out of technologies such as backwash sand washing like this, having improved influences fracturing effect.
The utility model is to realize like this, this kind sliding sleeve switch is made up of top connection, sliding sleeve switch, O type circle, gaslift ball-and-seat, by-pass prot, gaslift seating nipple main body, lower contact, top connection is connected successively with sliding sleeve switch, gaslift seating nipple main body, lower contact, between sliding sleeve switch and gaslift seating nipple main body O type circle is arranged, on gaslift seating nipple main body, gaslift ball-and-seat and by-pass prot are arranged.
The utility model is to install a cover sliding sleeve switch device on the by-pass duct of gaslift seating nipple again additional.The sliding sleeve switch device can be by the Ground Control opening and closing.When pressing crack construction, packer set is transferred tubing string then, and gaslift seating nipple sliding sleeve slides downwards is closed by-pass prot under action of gravity, and the gaslift seating nipple is not worked, and only is equivalent to oil pipe.(packer band backwash valve) just can be normally carried out in backwash sand washing if desired, fixed tubular column.After pressure break finished, the upper lifting pipe post was removed on the sliding sleeve on the sliding sleeve switch gaslift seating nipple and is opened, and the gaslift seating nipple just can operate as normal.
The utility model is connected with sliding sleeve switch, the lower contact of gaslift seating nipple main body successively owing to having adopted in top connection, between sliding sleeve switch and gaslift seating nipple main body O type circle is arranged, on gaslift seating nipple main body, gaslift ball-and-seat and by-pass prot are arranged, satisfy sand plug recoil sand needs in the pressure break gaslift discharge opeing construction; After new gas well gas is lifted discharge opeing, oil well that can not blowing, close behind the gaslift seating nipple can the situation of fixed tubular column under, directly descend insert pump production, the operation of minimizing one-trip string;
Easy for installation, simple to operate.Reliable operation is well suited for The field.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of top connection 1, sliding sleeve switch 2, O type circle 3, gaslift ball-and-seat 4, by-pass prot 5, gaslift seating nipple main body 6, lower contact 7, top connection 1 is connected successively with sliding sleeve switch 2, gaslift seating nipple main body 6, lower contact 7, sliding sleeve switch 2 and 6 of gaslift seating nipple main bodys have O type circle 3, and gaslift ball-and-seat 4 and by-pass prot 5 are arranged on gaslift seating nipple main body 6.
Claims (1)
1. sliding sleeve switch, form by top connection (1), sliding sleeve switch (2), O type circle (3), gaslift ball-and-seat (4), by-pass prot (5) gaslift seating nipple main body (6), lower contact (7), it is characterized in that: top connection (1) is connected successively with sliding sleeve switch (2), gaslift seating nipple main body (6), lower contact (7), between sliding sleeve switch (2) and gaslift seating nipple main body (6) O type circle (3) is arranged, gaslift ball-and-seat (4) and by-pass prot (5) are arranged on gaslift seating nipple main body (6).
