Abstract

The utility model provides a device for acquiring an oil sample from a water-containing oil well, which consists of a sampling port, a stirrer, a sampling barrel, a sieve plate, an oil-water discharging pipe and a bracket, wherein the sampling port is arranged at the upper end surface of the sampling barrel, the stirrer is arranged in the sampling barrel, a crank at the upper end of the stirrer is exposed out of the upper end surface of the sampling barrel, the sieve plate is arranged at the lower part in the sampling barrel and divides the sieve plate into an upper cavity and a lower cavity, the lower cavity of the sampling barrel is provided with the oil water discharging pipe, and the sampling barrel is arranged on the bracket. The liquid sample acquired from the mouth of the well can be separated in the sampling barrel, and then the crude oil is extracted to be taken as a sample for testing the physical property of the crude oil while the separated water is discharged into the well through the oil-water discharging pipe, so that the device is less in the work amount for sampling, is environment-friendly, and is remarkable in economic benefits and social benefits.

Description

Aqueous well oil sample collector

Technical field:

The utility model is the equipment of oil well mouth usefulness, is a kind of aqueous well oil sample collector.

Background technology:

Producing well will regularly be chemically examined the crude oil physical property, need get the oil sample of certain volume at well head, because well water amount height need be gathered considerable well liquid at well head and send chemical laboratory extraction crude oil back at present, then the crude oil that extracts is chemically examined, therefore, in taking the oil sample process, sampling amount is many at present, and workload is big, the water of separating reclaims nowhere, causes environment pollution.

Summary of the invention:

The purpose of this utility model is a kind of aqueous well oil sample collector of design, makes it can be at well head separation and Extraction crude oil, and the water sample of extraction returns in the well, reduces the sampling workload, reduces environment pollution.

The purpose of this utility model is achieved in that by sample tap, agitator, sample bucket, sieve plate, profit discharge piping, support to be formed, sample tap is installed in the upper surface of sample bucket, agitator is installed in the sample bucket, the upper surface that the crank of agitator upper end exposes sample bucket, sieve plate is installed in bottom in the sample bucket, sieve plate is divided into epicoele and cavity of resorption with sample bucket, and the cavity of resorption of sample bucket is installed the profit discharge piping, and sample bucket is rack-mount.

The beneficial effects of the utility model are: the liquid sample in the well head extraction can separate in sample bucket, crude oil is extracted as crude oil physical property sample for test, isolated water drains in the well through the profit discharge piping, therefore, the utility model sampling workload is little, can not cause environment pollution, have remarkable economic efficiency and social benefit.

Description of drawings:

Accompanying drawing 1 is the assembling drawing of the utility model embodiment.

The specific embodiment:

1 couple of embodiment of the present utility model describes below in conjunction with accompanying drawing.

Embodiment of the present utility model is made up of sample tap 1, agitator 2, sample bucket 3, sieve plate 4, profit discharge piping 5, support 6, sample tap 1 is installed in the upper surface of sample bucket 3, agitator 2 is installed in the sample bucket 3, the upper surface that the crank of agitator 2 upper ends exposes sample bucket 3, sieve plate 4 is installed in bottom in the sample bucket 3, sieve plate 4 is divided into epicoele and cavity of resorption with sample bucket 3, and the cavity of resorption of sample bucket 3 is installed profit discharge piping 5, and sample bucket 3 is installed on the support 6.

Profit discharge piping 5 is connected with the sleeve pipe of wellhead assembly, during use, open the sample cock on the wellhead assembly, well liquid is in sample tap 1 enters sample bucket 3, under the effect of profit density contrast, water sample through initial gross separation is discharged from profit discharge piping 5, through the crude oil of initial gross separation in the upper chamber that stays sample bucket 3, shake agitator 2, crude oil through initial gross separation is rotated separation in the upper chamber of sample bucket 3, the water of separating is put after rolling through profit discharge piping 5, and the pure crude oil of separating is taked through flowing out through profit discharge piping 5 again.
