Abstract
An adjustable oil nozzle is arranged on wellhead device used for oilfield self-jetting oil production well and oil-submersible electric pump oil production well, which is used to regulate the pressure and the yield of oil wells. The utility model consists of a plugging body, a regulating rod, a cone rod, an oil nozzle and an oil nozzle sleeve, wherein, a pin thread of the plugging body is in threaded connection with the upper part of the oil nozzle sleeve; a pin thread of the regulating rod is screwed with an inner thread of the plugging body; the cone rod is arranged below the regulating rod and connected with the regulating rod into a whole; the cone rod stretches into the oil nozzle; a thread of the oil nozzle is connected with a small thread inside the oil nozzle sleeve. A tool is inserted into an inner square hole at the end of the regulating rod and is rotated, leading the regulating rod to rotate; the cone rod produces axial movement; a ring-shaped space of the cone rod and the oil nozzle is changed, changing the over flow area of the oil nozzle, so as to change the pressure and the yield of an oil well for achieving the objective of regulation. The utility model can conveniently and rapidly regulate the pressure and control the yield of self-jetting oil production wells and oil-submersible electric pump oil production wells without stopping the production of oil wells, is small in workload, and has significant economic benefit.
Description
Technical field:
The utility model is the wellhead assembly that oil field oil flow production well, submersible electric pump producing well are used, and is a kind of adjustable choke.
Background technology:
In the wellhead assembly of oil flow production well, submersible electric pump producing well, all oil nozzle to be installed, in order to regulate well head pressure and control oil well output, according to the oil well situation with join the product requirement, need often to regulate the oil nozzle size, present prior art adjusting oil nozzle size will be closed dead by flow line, could change oil nozzle after stopping to produce, change the uncertain once success of oil nozzle, if change improperly, also need to change again, therefore, regulate oil nozzle bothers very much, workload is big, if the well of single oil nozzle also needs to close a well in, influences oil well output.
Summary of the invention:
The purpose of this utility model is a kind of adjustable choke of design, makes oil flow production well, submersible electric pump producing well regulate pressure and control output easily and fast, and oil well without stop produces, and workload is little.
The purpose of this utility model has been achieved in that the oil nozzle cover, also form by stifled body, adjusting rod, awl bar, oil nozzle, the top thread connection of the male thread of stifled body and oil nozzle cover, the male thread of adjusting rod and the internal thread of stifled body screw, the awl bar is below adjusting rod, be connected into one with adjusting rod, the awl bar stretches into oil nozzle, and the screw thread of oil nozzle connects with the minor thread of oil nozzle cover inside.
The beneficial effects of the utility model are: the rotation adjusting rod, the area of passage of oil nozzle is changed, thereby make the pressure and the change of production of oil well, reach the adjusting purpose, therefore, the adjustable choke of design can make oil flow production well, submersible electric pump producing well regulate pressure and control output easily and fast, and oil well without stop produces, workload is little, has significant warp and squeezes benefit.
Description of drawings:
Accompanying drawing is the utility model adjustable choke embodiment assembling drawing.
The specific embodiment:
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
As shown in the figure, form by stifled body 1, adjusting rod 2, joint ring 3, awl bar 4, oil nozzle 5, oil nozzle cover 6, the top thread connection of the male thread of stifled body 1 and oil nozzle cover 6, the internal thread of the male thread of adjusting rod 2 and stifled body 1 screws, awl bar 4 is below adjusting rod 2, be connected into one with adjusting rod 2, awl bar 4 stretches into oil nozzle 5, and the screw thread of oil nozzle 5 connects with the minor thread that oil nozzle overlaps 6 inside.Between stifled body 1 and the adjusting rod 2 joint ring 3 is installed.Oil nozzle cover 6o is the parts on the existing wellhead assembly, the external screw thread of stifled body 1 and the screw thread on the oil nozzle 5 all with wellhead assembly on oil nozzle overlap 6 and match.
Adjusting rod 2 ends are processed with interior square hole, during adjusting, rotate in the interior square hole with instrument insertion adjusting rod 2 ends, make adjusting rod 2 rotations, awl bar 4 produces and moves axially, and awl bar 4 changes with the annular space of oil nozzle 5, and the area of passage of oil nozzle 5 is changed, thereby make the pressure and the change of production of oil well, reach the adjusting purpose.The end face of oil nozzle 5 has designed groove, can prevent to bore to block runner when bar 4 contacts with oil nozzle 5 and cause oil well to stop production.
