Abstract
The invention provides a sucker rod ring seal movable sealer, which is characterized in that an upper casing provided with an upper hydraulic oil opening is connected onto a lower casing provided with a lower hydraulic oil opening, annular rubber cores and pistons connected with the rubber cores are connected in the lower casing, and the upper casing is arranged above the pistons. During oil well operation at pressure, the seal of rod columns such as sucker rods, hollow rods, pumps, eccentric wearing resistance devices and the like are removed, and the safe production is ensured.
Description
Technical field
The present invention relates to the well-control equipment of the underground work of petroleum industry; The sucker rod on Operating Pressure oil well annular movable sealing device particularly; The sealing of roofbolts such as sucker rod, hollow stem, pump, anti-eccentric wear device removes when being applicable to the oil well Operating Pressure, ensures safety in production.
Background technology
When oil well is implemented Operating Pressure, when playing lower sucker rod, need use the sealing of the self-styled realization roofbolt of sucker rod, because the sucker rod body is bigger with box cupling size difference, the self-styled sealing effectiveness of sucker rod is bad, and the wearing and tearing of sucker rod self-sealing rubber core comparatively fast; And the composition of sucker rod all is designed to built spar according to the load difference of bearing in the well; This just need change different sucker rod self-sealing rubber cores when removing the sucker rod of different size, have at well head under the situation of pressure, changes the sucker rod self-sealing rubber core; Operating difficulties, and cause environment pollution easily.
Summary of the invention
The object of the invention is intended to overcome the weak point of prior art; Provide a kind of roofbolt sealing load to adopt hydraulic control; Pressure is arranged in well and do not change under the situation of glue core, realize that the sealing of different size roofbolt removes, guarantee the sucker rod ring seal movable sealing device of Operating Pressure smooth implementation.
The object of the invention can be realized through following technical measures:
Be provided with the upper shell that is provided with hydraulic fluid port on the hydraulic oil on the lower house of hydraulic fluid port under the hydraulic oil, be connected with annular rubber core and the piston that is connected the glue core in the lower house, upper shell is arranged on the piston.
The object of the invention also can be realized through following technical measures:
-1-
Described glue core bottom is hemispherical and matches with the inner chamber of spherical in shape of lower house bottom; Described glue in-core has metallic framework; Described metallic framework radial equipartition; Described metallic framework is steel or iron skeleton; The latus rectum of described annular rubber core is 80mm; Described piston semi-section is " C " font structure; The upper end of described upper shell and the lower end of lower house are tubing thread; Described upper shell, lower house are provided with sealing ring with piston space respectively.
Upper shell of the present invention adopts bolton to connect with lower house.The glue core is hemispherical, in iron and steel skeleton radial equipartition is arranged, piston is connected with the glue core crab through screw thread.Upper shell, lower house two ends are designed to the standard oil pipe thread, are convenient to and the different operation technique of the supporting formation of different tools.
The present invention is that a kind of sucker rod annular movable sealing device by hydraulic control comes the sealing of different size sucker rod, hollow stem and other roofbolt to remove, and guarantees the smooth implementation of Operating Pressure.Little, the light weight, highly low of external dimensions of sucker rod annular movable sealing device is compared with existing sucker rod is self-styled, under the situation of not changing the glue core; The sucker rod of salable different size, plunger etc.; Improved operating efficiency greatly, in addition, this pumping rod sealer sealing load is by hydraulic control; Sealing load is high, thereby has improved the safety factor of Operating Pressure equipment.
Description of drawings:
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment:
Embodiment 1:
This sucker rod ring seal movable sealing device comprises upper shell (1), hydraulic fluid port on the hydraulic oil (2), piston (3), hydraulic fluid port (6), roofbolt (7) under lower house (4), glue core (5), the hydraulic oil.Be provided with the upper shell (1) that is provided with hydraulic fluid port on the hydraulic oil (2) on the lower house (4) of hydraulic fluid port under the hydraulic oil (6); Be connected with the annular rubber core (5) and the piston that is connected glue core (5) (3) that are positioned at roofbolt (7) outside in the lower house (4), upper shell (1) is arranged on the piston (3).Upper shell (1) adopts bolton to connect with lower house (4).Glue core (5) is hemispherical,
-2-
In iron and steel skeleton radial equipartition is arranged; Piston (3) is connected with the glue core crab through screw thread; Between upper shell (1) and the piston (3), adopt the sealing ring sealing between lower house (4) and the piston (3) respectively; Upper shell (1) is provided with hydraulic fluid port on the hydraulic oil (2), and lower house (4) is provided with hydraulic fluid port under the hydraulic oil (6).
When closing this sucker rod ring seal movable sealing device; Hydraulic oil gets into hydraulic fluid chamber from the hydraulic oil in the hydraulic fluid port (2), act on the piston (3), and piston (3) is gone up owing to there is upper shell (1) to stop; Therefore under action of hydraulic force; Piston (3) can only promote the sphere inner chamber motion of glue core (5) along lower house (4), pushes glue core (5) from top to bottom and draws in, is out of shape, thereby realize the roofbolt sealing.
When opening this sucker rod ring seal movable sealing device; Hydraulic oil gets into hydraulic fluid chamber under the hydraulic oil in the hydraulic fluid port (6); Act on the piston (3), piston (3) can only be under the pressure effect of hydraulic oil owing to moving to the travel point place; Drive glue core (5) moves upward, and advances to by upper shell 1 up to piston (3) to stop that the back motion puts in place.
In order to adapt to the actual needs of oil well Operating Pressure, the minimum diameter of the sealing roofbolt of this sucker rod movable sealing device is 16mm, and maximum can arrive 76mm, is enough to through roofbolts such as oil pump plunger piston general in the Operating Pressure, anti-eccentric wear devices.
