Abstract
A measuring analyzer for the water contained in the crude oil, belongs to the on-line measurement of the water contained in the crude oil, solving the problem in the existing measuring analyzer of the water contained in the crude oil that the radioactive pollution exists, or the measuring scope is narrow and the measuring precision is lower. The measuring analyzer comprises a vertical measuring container connected at the upper detection position of an oil-way, a differential pressure transmitter with piezometric tubes respectively inserted into the upper and lower ends of the measuring container, a temperature transmitter with a probe inserted into the measuring container, a flowmeter in series connection with the measuring container, a joint between the measuring container and the oil-way pipeline and a valve on the joint, a differential pressure, temperature, flow signal treated computer and a printer. The utility model has the beneficial effects that the measuring analyzer replaces the measuring analyzer with the radioactive material and a capacitance type water analyzer, is safe and environment-friendly, has no influence of the factors such as foam and hanging wax in the pipeline, and has the measuring scope of 0 to 100% and the measuring accuracy of +/-1%. The measuring analyzer of the utility model has the characteristics of scaling prevention, corrosion resistance, convenient operation and debugging and low cost. The utility model provide a new means for the on-line measuring of the crude oil in the oil field.
Description
Technical field
The utility model belongs to the measurement technical field of measurement and test, utilization be by means of measuring material physical properties test or analysis of material, being specifically related to on-line measurement device of crude oil water content.
Background technology
At present, to the oil field adopt, the online detection of water percentage of oil in the oil transportation process, employed water in oil analyzer has two kinds, a kind of detector that is to use the radiation essence, shortcoming is to have radioactive contamination, and contact personnel's health is had harm.Another kind is the condenser type analyzer of water content, and this type of analyser can only be measured accurately at a narrower section, does not reach the crude oil water containing analysis in the 0-100% scope.
In addition, heavy crude is easy to bubbing and forms stable bubble in the oil extraction transportation process, produce bubble effect, and above-mentioned measuring and analysing meter can be disturbed by it, cause crude oil water containing on-line measurement error to increase (error can reach 15%-45%), the measurement result confidence level reduces.
The utility model content
The purpose of this utility model provides a crude oil water containing measuring and analysing meter, is used for the crude oil water containing on-line measurement, and what overcome that existing crude oil water containing measuring and analysing meter exists has radioactive contamination or measurement range is narrow, measuring accuracy is a low deficiency.
The utility model is by the upright measuring vessel that inserts detection position on the oil circuit, piezometric tube stretches into the differential pressure transmitter of upper and lower end in the measuring vessel respectively, probe stretches into the temperature transmitter of measuring vessel, the flowmeter that is connected in series with measuring vessel, joint between measuring vessel and oil circuit pipeline and the valve on the joint, connect differential pressure transmitter, temperature transmitter, the pressure reduction of flowmeter, temperature, flow signal process computer, the printer that connects computing machine is formed.More than constitute the utility model basic scheme.
For preventing collide with differential pressure transmitter and the outer part of temperature transmitter measuring vessel, outside differential pressure transmitter and temperature transmitter, be surrounded by cabinet.
Principle of work of the present utility model is: the relation that changes into direct ratio according to detected fluid variable density and unit volume phase difference variable, utilize differential pressure pick-up to record the difference of phase change, after the machine Operations Control Procedure carries out calculating compensation such as pressure, temperature, flow as calculated, record fluid medium component content, draw water percentage.
Good effect of the present utility model is: substitute measuring and analysing meter and condenser type analyzer of water content that radioactive material is arranged, safety, environmental protection are not subjected to the influence of foam in the pipeline, extension wax or the like factor, and measurement range is wide, can measure water percentage 0%-100%.Accuracy of measurement ± 1%.Measuring accuracy improves an order of magnitude, at Daqing oil field six factories, one ore deposit, 102 terminals that recover the oil, carries out site test, and crude oil water containing shows contrast, and accuracy reaches ± and 1%.Efficiently solve the accuracy problems of crude oil water content on-line measurement.And have good antiscale property, corrosion-resistant, characteristics such as operation debugging convenient, cost is low.Be widely used in the on-line monitoring of crude oil water contents such as field joint stations, terminal, metering plant and the on-line measurement of various binary fluids etc.For the crude oil on-line measurement provides new means.
