Abstract
The utility model relates to an injecting polymer wellhead decompression and sampling device and consists of a valve body integrated with a stop valve, an inlet pipe joint and an outlet pipe interface. The upper part of the valve body is provided with a sampling outlet stop valve and a sampling inlet stop valve, and the lower part of the valve body is provided with an injecting polymer media outlet pipe and an injecting polymer media inlet pipe; the anterior of the valve body is provided with a blow-off valve and a sampling valve and the posterior of the valve body is provided with a blow-off pipe and a sampling pipe. The valve body has a channel flow which communicates the sampling outlet stop valve, the sampling inlet stop valve, the blow-off valve, the sampling valve with the media outlet pipe, the injecting polymer media inlet pipe, the blow-off pipe and the sampling pipe. The injecting polymer wellhead decompression and sampling device provided by the utility model has the advantages of fast and convenient sampling, small size and light weight, beautiful appearance, simple installation and maintenance, etc.
Description
Technical field
The utility model relates to oil recovery injection well sampler, particularly injection well mouth decompression sampler.
Background technology
Polymer displacement of reservoir oil is the new technology of tertiary oil recovery, and this technology is used widely in oil field development.In order to improve oil recovery factor, need certain polymer solution is injected the down-hole, improve the viscosity of polymer solution, this will take a sample to polymer solution.The wellhead sampling device that injection well is used all is portable sampler mostly but at present,, exist complicated operation, sample time is long, particularly is prone in the winter of severe cold and freezes clogging, the admission work that makes the notes of polymer well drive data has increased difficulty, influences ordinary production.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, provides a kind of in-line to make the injection well mouth decompression sampler that sampling storehouse internal pressure reduces, sampling is convenient and swift, true and reliable by stop valve.
Injection well mouth of the present utility model decompression sampler be by valve body integrated stop valve, inlet connector tube and outlet interface constitute.On valve body, be provided with sampling outlet stop valve and sampling inlet shutoff valve, below be provided with and annotate poly-media outlet pipe and annotate poly-medium inlet; Be provided with exhaust-valve and sample valve in the front side of valve body, be provided with evacuated tube and probe tube at rear side.
Further improve as the utility model, in valve body, have conduit that sampling outlet stop valve, sampling inlet shutoff valve, exhaust-valve, sample valve and media outlet pipe, the poly-medium inlet of notes, evacuated tube, probe tube are communicated with each other.
Injection well mouth of the present utility model decompression sampler has that the low temperature sampling is not degraded, the sampling in winter do not freeze stifled, reduce because of advantages such as emptying cause that waste, the sampling of annotating poly-liquid are convenient and swift, little in light weight, the good looking appearance of volume, installation and maintenance are easy.
Description of drawings
Fig. 1 is the front view of the utility model injection well mouth decompression sampler.
Fig. 2 is the upward view of the utility model injection well mouth decompression sampler.
The specific embodiment
Injection well mouth of the present utility model decompression sampler be by valve body 1 integrated stop valve, inlet connector tube and outlet interface constitute.On valve body 1, be provided with sampling outlet stop valve 2 and sampling inlet shutoff valve 3, below be provided with and annotate poly-media outlet pipe 4 and annotate poly-medium inlet 5.Be provided with exhaust-valve 6 and sample valve 7 in the front side of valve body 1, be provided with evacuated tube 8 and probe tube 9 at rear side.And in valve body 1, there is conduit that sampling outlet stop valve 2, sampling inlet shutoff valve 3, exhaust-valve 6, sample valve 7 are communicated with each other with media outlet pipe 4, the poly-medium inlet 5 of notes, evacuated tube 8, probe tube 9.
Injection well mouth decompression sampler of the present utility model when ordinary production, cuts out sample valve 7 and exhaust-valve 6, opens sampling outlet stop valve 2 and sampling inlet shutoff valve 3 fully.During sampling: close sampling outlet stop valve 2 earlier, close sampling inlet shutoff valve 3 then, make the completely poly-fluid injection of sampling storehouse stream.Open exhaust-valve 4 and make the decompression of sampling storehouse, open sample valve 7 samplings then by evacuated tube 8 emptyings.
