Description
Technical field
The utility model is related to oil field equipment technical fields, and in particular to a kind of horizontal well steam injection regulating valve.
Background technology
At present horizontal well horizontal segment steam injection amount is adjusted to realize by accessing perforated pipe, the disadvantage is that, 1：Tubing string enters
Steam injection amount size cannot be adjusted when well；2：The strength reduction of perforated pipe increases the possibility that tubing string is broken.
Utility model content
(1) technical problems to be solved
In order to overcome the shortage of prior art, it is proposed that a kind of horizontal well steam injection regulating valve is used for horizontal well steam injection, can be with
Each section of steam injection amount of horizontal segment is adjusted, also can guarantee the intensity into well casing column.
(2) technical solution
The utility model is achieved through the following technical solutions：The utility model proposes a kind of horizontal well steam injection regulating valve,
Including instrumentation tubes and inner sleeve, the tube wall of the instrumentation tubes is provided with several steam injection holes, and the inner sleeve socket joint is inside instrumentation tubes
And the sealing ring that sealing can be realized with inner sleeve inner wall is respectively arranged on its both ends tube wall, it is provided with several rings in the middle part of inner sleeve
Connected in star, is symmetrically arranged with a threaded hole on the tube wall of instrumentation tubes, and the threaded hole internal thread is connected in a bottom end is embedded in
Positioning screw in casing wall annular groove.
Further, the both ends of the instrumentation tubes are respectively arranged with an internal thread hole.
Further, instrumentation tubes described in any two are threadingly attached to the connection of the double male joint in internal thread hole.
Further, the both ends tube wall of the instrumentation tubes is provided with sealing ring mounting groove.
(3) advantageous effect
The utility model compared with the existing technology, has the advantages that：
A kind of horizontal well steam injection regulating valve that the utility model is mentioned is located at the position inside instrumentation tubes by adjusting inner sleeve
It sets, and is positioned by positioning screw, the adjusting for the steam injection hole number being connected to outside to instrumentation tubes may be implemented, to real
Now to the adjusting of steam injection amount, works at the same time pipe and the more casings of inner sleeve use and improve the intensity into well casing column.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
A kind of horizontal well steam injection regulating valve as depicted in figs. 1 and 2, including instrumentation tubes 1 and inner sleeve 2, the instrumentation tubes 1
Tube wall be provided with several steam injection holes 11,2 socket joint of the inner sleeve on 1 inside of instrumentation tubes and its both ends tube wall in being respectively arranged with energy
Enough and 2 inner wall of inner sleeve realizes the sealing ring 3 of sealing, and the middle part of inner sleeve 2 is provided with several annular grooves 21, the tube wall of instrumentation tubes 1
On be symmetrically arranged with a threaded hole 12,12 internal thread of the threaded hole is connected with a bottom end and is embedded in 2 tube wall annular groove of inner sleeve
Positioning screw 4 in 21.
Wherein, the both ends of the instrumentation tubes 1 are respectively arranged with an internal thread hole 13；Instrumentation tubes 1 described in any two pass through
The double male joint 5 being threadedly connected in internal thread hole 13 connects；The both ends tube wall of the instrumentation tubes 1 is provided with sealing ring mounting groove
22。
A kind of horizontal well steam injection regulating valve that the utility model is mentioned can pacify the regulating valve when specifically used
Whether the horizontal segment different parts loaded on oilfield horizontal well steam injection well need steam injection with specific reference to corresponding stratum and determine, meanwhile,
Corresponds to the steam injection amount on stratum according to the valve is calculated, adjusting inner sleeve 2 is located at the position in instrumentation tubes 1, can specifically be stretched by tool
Enter that length direction taps in instrumentation tubes 1 to inner sleeve 2 in instrumentation tubes 1, at this point, the note of inner sleeve 2 and 1 overlapping of instrumentation tubes
Steam vent 11 is in sealed condition, the quantity of instrumentation tubes 1 and the steam injection hole 11 of external communication can be determined at this time, then such as Fig. 1 institutes
Show, the internal thread hole 31 of 1 left-hand end of instrumentation tubes connect with well casing male screw is entered, while by 5 end connected pipes of double male joint,
And it is sent into underground, it, can be by the way that multiple regulating valves be carried out when a regulating valve cannot meet when the steam injection amount of needs
It is connected in series with, being specifically located at the instrumentation tubes 1 in two regulating valves by the connection of double male joint 5 can be realized two regulating valves
Series connection.
Embodiment described above is only that preferred embodiments of the present invention are described, not to this practicality
Novel conception and scope is defined.Without departing from the design concept of the present utility model, ordinary people in the field couple
The all variations and modifications that the technical solution of the utility model is made, should fall within the protection scope of the present utility model, this reality
With novel claimed technology contents, all record in detail in the claims.
