Description

A kind of fast water injection wellhead assembly
Technical field
The utility model relates to extracting device of oil technical field, is specifically related to a kind of fast water injection wellhead assembly.
Background technology
In the water injection well of existing various types of ground, oil field, be generally provided with 5 to 10 and above valve, Pressure gauge be provided with 4 to 6 and more than, wellhead manifold is many in double formulas or single-blade formula etc., and Flange joint was then 4 to 10 with last.Its wellhead assembly is the most more complicated, huge, heavy, not only carry inconvenience, and installation difficulty, maintenance are taken a lot of work,, staff remote particularly with some location comparisons is difficult to the water injection well arrived, the part of water injection well is numerous and jumbled various easy to be lost, lose, and the phenomenon such as junction Yi Fashengci leakage.All kinds of problems that these injection well head assemblies exist, make oil field that certain human and material resources, financial resources must be spent to maintain the normal effective operation of water injection well, can not reach efficiently, low consumption, the purpose of economizing type, and can affect and restrict the development in good health arriving water flooding to some extent.
Utility model content
The purpose of this utility model is the defect for prior art and deficiency, a kind of simple in construction is provided, a kind of fast water injection wellhead assembly reasonable in design, easy to use, it uses and arranges outer siphunculus in cross valve, and by constant voltage pipe, outer siphunculus ensures that two-way pressure balances, facilitate the fast water injection of water injection valve, and it has easy to use, simple to operate, the features such as practicality is good, with low cost.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of fast water injection wellhead assembly described in the utility model, including end pipe and four-way pipe, pipe upper end, the described end is provided with four-way pipe, inner sleeve and outer siphunculus it is provided with in described four-way pipe, described four-way pipe upper end is provided with envelope valve, constant voltage pipe it is provided with on the right side of described four-way pipe, described constant voltage pipe lower end is provided with bottom valve, upper end is provided with logical valve, it is provided with water injection valve on the left of described four-way pipe, described outer siphunculus lower end is provided with circulation compressing tablet, and described circulation compressing tablet is arranged between four-way pipe tube wall and inner sleeve.
Described circulation compressing tablet uses the sheet metal with wheel shaft, by sheet metal on wheel shaft, it is possible to play iris action, can be by break-make upper and lower for outer siphunculus, ensure that the pressure balance of both water fillings, prevent pressure bounce-back while improving flood effectiveness, affect outer through-pipe structure.
Use two to lead to nut between pipe of the described end and four-way pipe to fix, described two lead to nut uses stainless steel material, uses two to lead to nut connecting bottom tube and four-way pipe, has good dismoutability, use stainless steel material simultaneously, there is good connection effect and good steadiness.
After using said structure, the utility model has the beneficial effect that its employing of the utility model arranges outer siphunculus in cross valve, and by constant voltage pipe, outer siphunculus ensures that two-way pressure balances, facilitate the fast water injection of water injection valve;Bottom valve is used to control the setting of constant voltage pipe with logical valve, it is possible to be easy to control the break-make of constant voltage pipe, regulate the pressure of outer siphunculus as required;The setting using circulation compressing tablet ensure that the interval between inner sleeve and outer siphunculus, places and rushes outside internal pressure;And it has easy to use, simple to operate, the features such as practicality is good, with low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Description of reference numerals:
1, end pipe;2, four-way pipe;3, inner sleeve;4, outer siphunculus;5, water injection valve;6, constant voltage pipe;7, bottom valve;8, logical valve;9, upper envelope valve;10, circulation compressing tablet;11, two lead to nut.
Detailed description of the invention
Below in conjunction with the accompanying drawings the utility model is further described.
As shown in Figure 1, a kind of fast water injection wellhead assembly described in the utility model, including end pipe 1 and four-way pipe 2, pipe 1 upper end, the described end is provided with four-way pipe 2, inner sleeve 3 and outer siphunculus 4 it is provided with in described four-way pipe 2, described four-way pipe 2 upper end is provided with envelope valve 9, it is provided with constant voltage pipe 6 on the right side of described four-way pipe 2, described constant voltage pipe 6 lower end is provided with bottom valve 7, upper end is provided with logical valve 8, being provided with water injection valve 5 on the left of described four-way pipe 2, described outer siphunculus 4 lower end is provided with circulation compressing tablet 10, and described circulation compressing tablet 10 is arranged between four-way pipe 2 tube wall and inner sleeve 3.
Described circulation compressing tablet 10 uses the sheet metal with wheel shaft, by sheet metal on wheel shaft, it is possible to play iris action, can be by break-make upper and lower for outer siphunculus, ensure that the pressure balance of both water fillings, prevent pressure bounce-back while improving flood effectiveness, affect outer through-pipe structure.
