Abstract
The utility model discloses the disconnected de-preventer of a kind of oil well polished rod, including the fixed plate bottom packing box and portable plate in being arranged on joint hoop, leave light rod aperture in the middle of fixed plate, the size of light rod aperture is consistent with the diameter of polished rod.A kind of oil well polished rod of this utility model de-preventer that breaks is prevented from oil well polished rod and breaks the de-generation causing blowout.
Description
Technical field
This utility model belongs to oil exploration equipment technical field, relates to the disconnected de-preventer of a kind of oil well polished rod.
Background technology
Light rod-broken is a kind of phenomenon often occurred in oil well production process, the most easily ruptures in clamp position, installation side.
Sucker rod thus can be made to fall well, and polished rod, also with falling in well, causes light rod aperture in production tree to communicate with the external world.Destroy oil
The confined space of pipe.Oil gas water in oil pipe can spray oil well by light rod aperture.The defeated well of non-collection: the oil that pressure (1-2MP) sprays
Post is high up to 8-10 rice.Oil spout duration is until pressure is 0MP, the most all about half an hour；Oil spout number formulary is the most all at 2-4
Side, oil spout area about 30 square meters, has wind area to be likely to be breached tens mu or bigger at calm weather area.Oil pumper is every
Secondary is all thorough blackening.So in oil well production process, light rod-broken causes oil spout to be very to the harm produced, environment brings
Huge.
Utility model content
The purpose of this utility model is to provide the disconnected de-preventer of a kind of oil well polished rod, it is possible to prevent disconnected the taking off of oil well polished rod from causing
The generation of blowout.
This utility model be employed technical scheme comprise that, the disconnected de-preventer of a kind of oil well polished rod, bottom packing box
Fixed plate binds round interior portable plate with being arranged on joint, leaves light rod aperture in the middle of fixed plate, and the size of light rod aperture is consistent with the diameter of polished rod.
Feature of the present utility model also resides in, and portable plate is connected with fixed plate by portable plate steady pin, and portable plate can
To rotate certain angle around portable plate steady pin.
Be internally provided with interior screw thread, the interior screw thread of joint hoop and the male thread of packing box of the tube wall of joint hoop are connected.
Being provided with an anti-canting pin between portable plate and tube wall, anti-canting pin and portable plate weld together, and rise
Arrive the effect supporting portable plate.
The beneficial effects of the utility model are, this utility model utilizes single current principle, send out when the disconnected de-oil spout of oil well polished rod
Wave its blowout prevention effect, harm that the light rod-broken oil spout that conscientiously solves to know clearly brings and loss, thus reduce production cost, prevent
Environmental pollution.
Accompanying drawing explanation
Fig. 1 is that this utility model oil well polished rod breaks the structural representation of de-preventer.
In figure, 1. portable plate, 2. portable plate steady pin, 3. anti-canting pin, 4. tube wall, 5. male thread, the most smooth rod aperture, 7.
Fixed plate, 8. in screw thread, 9. packing box, 10. joint hoop.
Detailed description of the invention
With detailed description of the invention, this utility model is described in detail below in conjunction with the accompanying drawings.
The disconnected de-preventer of a kind of oil well polished rod, as it is shown in figure 1, include the fixed plate 7 bottom packing box 9 and be arranged on joint hoop
Portable plate 1 in 10, leaves light rod aperture 6 in the middle of fixed plate 7, and the size of light rod aperture 6 is consistent with the diameter of polished rod.Portable plate 1 passes through
Portable plate steady pin 2 is connected with fixed plate 7, and portable plate 1 can rotate certain angle around portable plate steady pin 2.Joint hoop 10
Tube wall 4 be internally provided with interior screw thread 8, the interior screw thread 8 of joint hoop 10 and the male thread 5 of packing box 9 are connected.
It is provided with an anti-canting pin 3, anti-canting pin 3 and portable plate 7 between portable plate 1 and tube wall 4 and is welded on one
Rising, serving the effect supporting portable plate, so that being kept at an angle between itself and tube wall.
Smooth rod break anti-blowout apparatus, when oil well normally produces, itself only plays interconnection function, does not affect normal production.When
After light rod-broken, it adopts its blowout prevention effect of performance.Concrete work process is, when oil well normally produces, polished rod is positioned at fixed plate
In light rod aperture 6 in the middle of 7, work normally, now with the isopiestic state of confined space at the portable plate 1 in preventer
Under, can naturally droop under gravity, and be supported by anti-canting pin, so that being formed certain between portable plate and tube wall
Angle, portable plate under naturally drooping state and between polished rod not in contact with, so can never wear and tear polished rod and portable plate
Itself.
When oil well polished rod occurs disconnected taking off, polished rod is fallen in well by light rod aperture, and the confined space of oil pipe is destroyed, and oil gas leads to
Cross the ejection of light rod aperture.At this moment polished rod break-off blowout preventer plays a role, when oil gas is sprayed by light rod aperture, and polished rod break-off blowout preventer
Portable plate would be at anisobaric space.Pressure differential is formed owing to falling polished rod in well makes light rod aperture be in communication with the outside.Oil gas
Can flow to the external world that pressure is zero from the oil pipe that pressure is high, at this moment oil gas outflow can form upthrust.Utilize this upthrust,
Make to turn on the portable plate of polished rod break-off blowout preventer, thus block light rod aperture, reach blowout prevention effect to stop oil gas to continue to flow out.
