Abstract
The utility model relates to an oil well sampling device, in particular to a composite sampling device for an oil well. The composite sampling device is applied to a wellhead in an oil field, and comprises flanges, an outer tube, a multi-stage mixing unit and an anti-theft sampling valve. The utility model is characterized in that the two ends of the outer tube are welded with the two flanges respectively, the multi-stage mixing unit is welded on the inner wall of the outer tube, and the anti-theft sampling valve is perpendicularly welded with the outer tube in a penetrating manner and positioned at the tail end of the multi-stage mixing unit. The utility model has the benefits that: the fluid state of the oil-well produced fluid in the pipeline is changed from laminar flow to turbulent flow, the oil-well produced fluid is completely mixed and homogenized, and the sample from the sampling valve can truly reflect the water content of the oil-well produced fluid in the pipeline.
Description
Technical field:
The utility model relates to a kind of oil well sampler, particularly a kind of hybrid sampler of oil well that is used for oil field shaft mouth.
Background technology:
At present, well mouth of oil well sample examination production fluid moisture content is important procedure in the oil well production, and the method that adopts now is that the sampling cock is installed on the well head oil pipeline, directly takes out oil sample in the pipeline.Along with oil field development gets into the middle and later periods; Have a large amount of free waters in most produced liquid in oil well, because the fluid major part in the pipeline is the laminar flow nonturbulent flow, the sample of obtaining like this can not truly reflect the composition of liquid in the pipeline; The crude oil water content data that chemical examination obtains exist very big error; Error so just can't accurately be checked crude oil water content up to 30%, also just can't measure the oil production of oil well.
Summary of the invention:
In order to overcome the deficiency of prior art; The utility model provides a kind of oil well hybrid sampler, and the hybrid sampler of this oil well can make the liquid in the pipeline fully mix, and forms turbulent flow; Become homogenieity to flow; Thereby realize that oil well takes out the homogenieity of sample, chemically examine out the real constituent content of liquid, accurately measure the oil production of oil well.
The utility model solves the technical scheme that its technical problem adopted: the hybrid sampler of a kind of oil well; Form by flange, outer tube, multistage mixed cell and anti-theft sampling valve; Its characteristic part is: each welds the two ends of outer tube with a flange mutually; The inwall of outer tube welds multistage mixed cell, and anti-theft sampling valve is vertical with outer tube to run through welding, and at the end of multistage mixed cell.
The beneficial effect of the utility model is: can realize that the fluidised form of oil well liquid-producing becomes turbulent flow by laminar flow in the pipeline, output liquid fully mixes, homogeneous, and the sample that takes out through sample valve truly reflects the moisture content of oil well liquid-producing in the pipeline.
Description of drawings:
Accompanying drawing is the structural representation of the utility model.
Among the figure: 1 forward flange, 2 multistage mixed cells, 3 outer tubes, 4 anti-theft sampling valves, 5 rear flanges.
The specific embodiment:
In conjunction with accompanying drawing an embodiment is described:
Among Fig. 1: forward flange 1 and the welding of outer tube 3 front ends, multistage mixed cell 2 and outer tube 3 interior welds, anti-theft sampling valve 4 vertically run through outer tube 3 and welding mutually in multistage mixed cell 2 downstream, rear flange 5 welds with the other end of outer tube 3 mutually.When the non-homogeneity produced liquid in oil well behind the hybrid sampler of pipe flow will oil-feed well; Through reaching the abundant mixing of crude oil and free water after shunting, interflow and the rectification of multistage mixed cell 2; Form the homogenieity flow of turbulent condition; Open the anti-theft sampling valve 4 of multistage mixed cell 2 ends like this, just can get the true component sample of produced liquid in oil well, just can calculate the true oil production of oil well through the assay of sample.
