Description
Technical field
The utility model relates to oil field aid technical field, is specifically related to a kind of oil well crude oil sampler.
Background technology
Whether the oil production whether oil well sampling is accurately related to oil well is accurate, and oil sample data also have important references meaning to the analysis of oil field geologic.Current sampler mainly adopts and installs pipe nipple, sample valve and mozzle additional and sample on wellhead tree tree flow line, because crude oil sample flows out from oil pipe tube wall, fluid flowing has non-homogeneity, when containing free water in oil well, because water and oil exist differences in viscosity, the good fluidity of water, crude oil fluidity is poor, cause water and oil gas flow at high speed in the middle of pipeline, crude oil flows along tube wall, therefore, this sampling mode accurately cannot measure the real moisture ratio of the inner crude oil of oil pipe, has a strong impact on the reference value of sampled data; In addition, owing to easily remaining dead oil before pipe nipple, need the inconvenience this part dead oil emptying being caused sampling during sampling, and cause unnecessary waste.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of reasonable in design, be beneficial to pipeline fluid to mix, be beneficial to the reference value improving sampling fluid data, avoid causing the oil well crude oil sampler analyzed data and depart from reality owing to sampling inequality.
For solving the problems of the technologies described above, the technical solution of the utility model is: oil well crude oil sampler, for the crude oil collection in vertical petroleum pipeline, comprise sampling efferent duct, described sampling efferent duct is provided with sampling control valve, in described petroleum pipeline, body direction is provided with round table-like material distribution cartridge, described material distribution cartridge increases gradually along the cross section in crude oil flow direction, described material distribution cartridge is evenly distributed with cloth hole, the external diameter of described material distribution cartridge bottom is equal with the internal diameter of described petroleum pipeline, described material distribution cartridge bottom is connected with sampling mozzle, described sampling draft tube outlets is connected with described sampling efferent duct, be positioned at and sample efferent duct described in described sampling control valve crude oil input and be provided with crude oil return duct, described crude oil return duct outlet is stretched in described petroleum pipeline.
As preferred technical scheme, described material distribution cartridge top is provided with at least two support arms, and described support arm one end is fixedly connected with petroleum pipeline inwall, and the other end is fixedly connected with described material distribution cartridge top.
As the improvement to technique scheme, the introduction part that described sampling mozzle comprises the horn-like and conduction part of opening upwards and is communicated with described conduction part, described introduction part is communicated with described sampling efferent duct.
As the improvement to technique scheme, the external diameter on described material distribution cartridge top is not less than 1/2 of described material distribution cartridge bottom external diameter.
The utility model is by adopting technique scheme, there is following beneficial effect: petroleum pipeline Crude Oil effectively can be disperseed mixing by described material distribution cartridge, improve the homogenieity of taking crude oil sample, avoid causing the problem analyzed data and depart from reality owing to sampling inequality, be beneficial to the reference value improving oil sample data; Simultaneously owing to arranging crude oil return duct on sampling efferent duct, avoid crude oil easily forms dead oil problem at pipe nipple place, not only increase sampling convenience, and avoid unnecessary waste.
Accompanying drawing explanation
The following drawings is only intended to schematically illustrate the utility model and explain, does not limit scope of the present utility model.Wherein:
Fig. 1 is the structural representation of the utility model embodiment;
