Abstract

A sampling bottle for a mixture of oil and gas/water, comprising a cylindrical container body (1) having lockable (9, 8) end pieces (2, 3), and a piston (7), includes a mixer comprising a pump-driven (P) nozzle (10), the spray outlet (10') thereof being directed into the interior of the sampling bottle. One of the end pieces (2) is formed with a return channel (5) to the pump (P) to enable the content of the sampling bottle to be recirculated several times through nozzle (10). <IMAGE>

Description

The present invention relates to arrangements in sampling bottles for a gaseous/liquid sample medium, possibly a two-phase sample medium, e.g. in the form of a mixture of oil and gas/water, comprising a cylindrical container body having lockable end pieces, in which, possibly, sealable/closable passages have been formed, said sampling bottle internally being provided with partly a freely axially displaceable piston, partly a mixing means for mixing the sample medium within the sampling bottle.
A sampling bottle of this kind is known from Norwegian patent application No. 914949.
In this known sampling bottle, said mixing means consists of a driven propeller for mixing the sample medium. The propeller is axially compressible, and the freely displaceable piston within the sampling bottle is formed with a countersunk portion facing the propeller, for the accommodation of the axially compressible propeller in one of the end positions of the piston.
However, experiences have shown that such a driven propeller within the sampling bottle was not particularly successful as mixing means; with this known mixing device one did not achieve a representative sample of the content of the sampling bottle, this being due to the fact that the degree of mixing obtained with the propeller was insufficient.
The object of the present invention has been to provide a mixing means for the sampling bottle defined above, with which a very representative sample of the content of the sampling bottle, based on a unique degree of mixing can be achieved.
In accordance with the invention, this object is realized through designing the mixing means of the sampling bottle according to the features appearing from the annexed claims.
Thus, according to the invention, as mixing means at least one nozzle or similar throttled orifice or mouth, driven by means of a pump is used.
In order to obtain a homogeneous mixture of e.g. oil and water/gas within a sampling bottle, the content of the bottle is pumped through the pump-driven nozzle. Normally, the nozzle is inserted into a through-bore of one end piece of the sampling bottle, and in the same end piece there is formed a sealable/closable return channel to the pump of the nozzle, so that the content of the sampling bottle can be recirculated one or several times to and through the pump, and from there able to be sprayed each time into the interior of the bottle through the nozzle.
Such a pump-driven mixing nozzle or similar throttled orifice or mouth can be designed with such a small outlet opening that the speed of the sample medium causes the shearing stresses to exceed the surface tension of the water droplet. The water is thereby broken into sufficiently small droplets (emulsion) in order to be stable within the oil. The smaller the droplets, the larger the stability.
In this way, one obtains a representative sample of the content of the sampling bottle after the content has been pumped one or more times through the nozzle by means of the pump.
Whenever the sample medium is considered sufficiently mixed, one takes out a smaller sample thereof, and transfers it to the laboratory for further examination. Thus, the purpose of this thorough mixing is to obtain a representative sample of the content of the sampling bottle, and this cannot be achieved without a careful mixing of the content of the bottle.
An example of a preferred embodiment of a sampling bottle having a mixing means according to the invention is further explained in the following, reference being made to the accompanying drawing, the single figure thereof showing an axial section through a sampling bottle exhibiting features characterizing the present invention.
According to the figure of the drawing, a sampling bottle for a gaseous/liquid sample medium, possibly a two-phase medium, e.g. in the form of oil and gas/water, comprises a cylindrical container body 1 having lockable end pieces 2 and 3 which have throughbores 4, 5 and 6 that may be sealable/closable.
Internally, the sampling bottle is provided with an axially freely displaceable piston 7.
The closable axially directed through-bore 6 of the end piece 3 serves to enable evacuation of the cylindrical space between the piston 7 and the end piece 3, this being done in connection with the filling of the bottle. The filling of the bottle and associated operations are assumed to be well-known by those skilled in the art and are, therefore, not described further here.
The end piece 3 is, in per se known manner, locked in the inserted position by means of four radially directed screw-like locking means 8 which are screwed into threaded blind bores of the end piece 3 and pass through aligned unthreaded holes in the cylinder wall 1. The other end piece 2 is locked in a similar manner, the screw-like locking means being denoted at 9.
In the embodiment, a nozzle body 10 has been inserted into one through-bore 4 of the end piece 2, the spraying opening 10' being approximately aligned with the inner end face 2' of the end piece 2.
The nozzle 10 or similar throttled orifice or mouth is coupled via a hose/pipe line 11 to a pump P the suction side of which, through a hose/pipe line 12, is coupled to the other sealable/closable through bore 5 of the end pieced such that the content of the sampling bottle can be circulated/recirculated a desired number of times through the pump P in order, subsequent to each suction step, to be sprayed out through the spraying opening 10' of the nozzle body 10. The said opening may be made so small that an emulsion of e.g. oil and water is achieved, the shearing stresses exceeding the surface tension of the water droplets, whereby the particles of the resultant mixture become very small, enhancing the degree of mixing.
After one assumes that the content of the sampling bottle has been sufficiently mixed, one takes out a smaller sample to be sent to the laboratory for further examination.

Claims (4)

1. An arrangement in a sampling bottle for a gaseous/liquid sample medium, comprising a cylindrical container body having lockable end pieces each of which is formed with at least one sealable/closable through-bore, said sampling bottle being internally provided with a freely axially displaceable piston and a drivable mixing means for mixing the content of the sampling bottle, said mixing means including at least one pump-driven nozzle, throttled orifice or mouth.
2. An arrangement as claimed in claim 1, in which the body of said nozzle is inserted into one through-bore of one end piece, the aperture of the nozzle being substantially aligned with the axially inner end face of respective end piece.
3. An arrangement as claimed in claim 1 or 2, in which one end piece is formed with a further through-bore/channel constituting a return channel to the suction side of the pump so that the content of the sampling bottle can be circulated/recirculated to the pump in order to be sprayed a plurality of times into the interior of the sampling bottle through the nozzle aperture.
4. An arrangement according to any preceding claim subsequently as herein described with reference to and as shown in the accompanying drawing.
