Abstract
The utility model discloses a hydraulic sucker rod well packer, comprising a bearing flange and an oil cylinder sealing sleeve. The side of the lower part of the oil cylinder sealing sleeve is provided with an oil feeding hole and a spray pressure relief hole and the bottom is provided with a connecting clamp head. A compacting plunger and a sealing adhesive cylinder are arranged in the oil cylinder sealing sleeve, and the bearing flange and the oil cylinder sealing sleeve are fixedly connected by screw bolts. The utility model has the advantages of simple structure, high operation pressure, good sealed effect, long service life and convenient operation.
Description
Technical field
The utility model relates to a kind of well head sucker rod blowout preventer, is applicable to operation team in removing the rod string process, and annular space and band between sealing oil pipe and the sucker rod compress and wash well operations etc., belongs to the rig tool that the oilfield operation is used.
Background technology
Operation team is repaiied in oil field big (little), in the rod job process, often occurs blowout and overflow problem between the well head R a T, both has been unfavorable for safety and environmental protection, also influences the operation and the oil well job scheduling of operating worker.And the serious well of this class blowout and overflow barreler just, to recover this class oil well yield as early as possible, require the activity duration to shorten, sometimes also need load onto polished rod sealer again, by having continued lower sucker rod after the anti-circulation kill-job, pollute or stop up also may for during kill-job the production oil reservoir.
Summary of the invention
The purpose of this utility model removes in the rod string process in order to solve exactly, the blowout that occurs between the R a T and the problem of overflow, and designed a kind of hydraulic oil pumping bar blowout preventer.
The purpose of this utility model is achieved in that hydraulic oil pumping bar blowout preventer is made up of pressure-bearing flange and cylinder seal cover, cylinder seal cover lower side has fuel feed hole and open flow pressure relief vent, the bottom is the jointing clip head, in the cylinder seal cover clamping piston and cartridge are housed, are connected and fixed with bolt between pressure-bearing flange and the cylinder seal cover.
The utlity model has simple in structure, operating pressure height, good sealing effect, long service life, advantage such as easy to operate.
Description of drawings
Fig. 1: the utility model structural representation;
Among the figure: 1-pressure-bearing flange, 2-clamping piston, 3-cartridge, 4-open flow pressure relief vent, 5-clip head,
6-fuel feed hole, 7-cylinder seal cover, 8-bolt;
The specific embodiment
As shown in Figure 1, hydraulic oil pumping bar blowout preventer is made up of pressure-bearing flange 1 and cylinder seal cover 7, cylinder seal overlaps 7 lower side and has fuel feed hole 6 and open flow pressure relief vent 4, the bottom is a jointing clip head 5, in the cylinder seal cover 7 clamping piston 2 and cartridge 3 are housed, are connected and fixed with bolt 8 between pressure-bearing flange 1 and the cylinder seal cover 7.
When carrying out workover treatment, the clip head 5 of this device is connected on the well head four-way upper flange, remove the weight of rod string, pass and be added on the well head big four by rod elevator, blowout preventer pressure-bearing flange 1, cylinder seal cover 7, and clamping piston 2 and cartridge 3 are not subjected to the influence of roofbolt weight; Will be when sealing between the well head R a T, the interior hydraulic oil that injects of hydraulic cylinder that can utilize hydraulic pump or hydraulic hand-pump to constitute for oil cylinder sealing shroud 7 and clamping piston 2 by fuel feed hole 6, the fluid cylinder internal pressure raises, and makes cartridge 3 generation radial deformations and reaches the purpose that seals oil pipe and sucker rod space.
