Description
Technical field
The present invention relates to measurement of water ratio technical field, and in particular to a kind of oil truck is unloaded water content metering device.
Background technology
In oilfield development process, certain moisture, former Water in oil are directly typically contained from oil field produced crude oil
Difficulty can be brought to the processing of crude oil, increase the energy consumption of equipment, therefore the water content for measuring crude oil is very necessary, it is most common at present
Transportation oil be exactly oil truck transport, and during oil truck transports crude oil measure crude oil weight and water content in crude oil
It is a kind of very feasible mode.
Moisture content is measured during oil truck is unloaded at present mainly to measure with analyzer of water content by manually chemically examining, it is manual
Test the main point of upper, middle and lower three that carries out by the way of 3 points of samplings to sample, sample hands over laboratory to be chemically examined after sampling.This
Operating method, 3 points of upper, middle and lower sample the moisture content that can not represent vehicle, representative poor, chemical examination time length, and worker's work is strong
Degree is big, and efficiency is low；Analyzer of water content can measure moisture content in real time, the real-time change for reflecting moisture content in oil truck, but by
Profit layering is there may be in oil truck, pure water and pure oily be present, oil-in-water, Water-In-Oil, institute also be present
Big to measure difficulty, another factor unloads that vehicle speed is non-constant, and error caused by when calculating average moisture content is larger.And
In crude oil dynamic measuring, temperature not only directly affects the calculating of crude oil normal volume, is also played not in meter proof work
Negligible effect.Either crude oil normal volume or meter proof work finally can all influence pure oil mass clearing, and then
Have influence on the economic interests of crude transition both sides.Oil mass handing-over tool continuity, the big feature of handing-over amount, crude oil is typically in fluid or half
Fluid state, having can micro- compressibility.The same with other fluids, temperature change certainly will cause Volume Changes, and therefore, temperature is to original
The metering of oily water content also plays very important effect, still, in actual applications, the typically no shadow for considering this respect
Ring, so as to cause the water content that finally calculates less accurate.
The content of the invention
The problem of for presently, there are, the present invention provide a kind of oil truck and unloaded water content metering device, device increase
Flow-compensated and temperature compensation function, solves the influence of flow velocity and temperature to measurement, and measurement result is more accurate.
To achieve these goals, the present invention adopts the following technical scheme that：
A kind of oil truck is unloaded water content metering device, described device include measurement pipeline section, analyzer of water content, oil storage tank,
Oil discharge pipe, emptying interface, data processing unit, panel and host computer, one end of the measurement pipeline section and the emptying of oil discharge pipe
Interface connects, in oil discharge pipe's insertion oil storage tank；The analyzer of water content embeds flow sensor, the measurement of analyzer of water content
End is inserted in the measurement pipeline section, and analyzer of water content connects with data processing unit, data processing unit electrical connection panel, panel
Electrically connect host computer.More specifically, the analyzer of water content connects data processing unit, the face by signal-transmitting cable
Plate connects host computer by 232 communication cables.
Preferably, the measurement pipe section model DN100/150.
Analyzer of water content selected by the present invention is measured simultaneously using capacitance method and impedance method, the measurement end of analyzer of water content
Capacitive dielectric constant and impedance signal can be measured simultaneously, and moisture content is due to oil-in-water and You Bao being present when normal electricity consumption holds measurement
The state of water, so moisture content is two different curves from 0-100 and moisture content from 100-0, at this moment need to survey by impedance
The signal of amount judges it is in which bar curve, is measured again by capacitance method after judging which good bar curve, impedance method measurement is straight
Connecing and measure his impedance value, the linearity is preferable, and the curve of curve and 100-0 from 0-100 can overlap substantially, but low precision,
So with impedance method judgment curves, capacitance method measures, and both combine, and the data measured are more accurate, reliably.
Wherein, the data processing unit includes signal acquisition, processing, control circuit, for being detected to analyzer of water content
Collection, processing and the controlling transmission of signal are to panel.
Also, further, the panel shows provided with power supply indicator, temperature, pressure, instantaneous delivery and integrated flow

Further, described device also includes weighbridge, and the weighbridge is connected with analyzer of water content, for weighing oil truck
Weight.
Further, the host computer also connects with weighbridge, and host computer is used for what is measured according to analyzer of water content
Crude oil water content and the crude oil weight of unloading obtain water content in crude oil.
It is highly preferred that the flow sensor has two temperature sensors, one is used to measuring oil temperature, one with plus
Thermal element, by measuring heat that heating element heater is pulled away to calculate the flow of fluid, and then average moisture content is flowed
Amount compensation, while carry out temperature-compensating to average moisture content.The method of calculating flux of the fluid：Using thermal diffusion principle, heat
Diffusion technique is the high technology of a kind of function admirable under severe conditions, reliability.Two temperature sensors are placed in medium
When, one of sensor is heated to temperature more than environment temperature, and another temperature sensor is used for induction medium temperature
Degree.Velocity of medium increase, the heat that medium is taken away increases, the temperature differences of two temperature sensors by with the change in flow of medium and
Change, according to temperature difference and the proportionate relationship of velocity of medium, the flow Q of fluid can be drawn.
Because oil truck is among the process of unloading, with the change of oil product liquid level in oil truck, the velocity variations unloaded compared with
Greatly, speed during beginning, moisture content is higher, and unloading vehicle speed with the reduction of liquid level in oil truck constantly slows down, water content
Declining, discounting for flow rate effect, high-moisture percentage when starting to unload accounts for that weight is less, and later stage low-water-content accounts for power
Weight is larger, and the average moisture content integrally measured will be relatively low, and error is brought to metering, after adding flow velocity compensation, velocity of discharge shadow
Ring, improve measurement accuracy, shared weight will not substantially change when no matter speed speed measures, therefore the present invention is carried out to moisture content
Flow-compensated, the data measured are more accurate.
Further, since crude oil, under temperature change, its mass change is also obvious, therefore flow sensor is provided with
Temperature sensor, the temperature sensor can measure the situation of change of crude oil temperature, and temperature change has one with oil density change
Fixed rule, and according to the standard of GB/T1885-1998 (product section, crude oil part), the change of temperature and oil density
Change numerical value be one-to-one, as long as temperature is corresponded to the numerical value of oil density table, input into computer, crude oil temperature
During change, density changes therewith, and the temperature of every bit all corresponds to a density, the original that such water in oil analyzer calculates
Density can at this moment oily proportional volume is multiplied by a temperature of draws the quality of crude oil.Therefore, the present invention carries out temperature to moisture content
Degree compensation, the data measured are more accurate.
Specifically, the circular of temperature-compensating is：Design temperature a reference value first, then configure fixed moisture content
Oil mixing with water medium, medium enters EGR, temperature be often raised and lowered once water-cut variation how much, such as temperature liter
High A DEG C of Δ, moisture content rise Δ a, then current moisture content to subtract Δ a, moisture content convert back under fiducial temperature, it is on the contrary also
So；
Flow velocity compensation method is：Benchmark flow velocity is set first, when flow velocity often increases or decreases a certain amount of, sees water-cut variation
How much, current moisture content is subtracted or plus water-cut variation value, the moisture content being transformed under benchmark flow velocity, eliminate flow velocity change
Change the influence to moisture content and just complete flow velocity compensation.
The working method of the present apparatus is as follows：
The informations parameter such as oily flow velocity, temperature, pressure are gathered by the contact jaw of analyzer of water content and oil product first, passed through
Analyzer of water content is analyzed above-mentioned parameter, calculates instantaneous moisture content, according to the influence of temperature, flow velocity to moisture content, is adjusted
The relation of the temperature, flow velocity and the moisture content that are calculated with host computer, average moisture content is flowed by data processing unit
Speed and temperature-compensating, are then shown the real time temperature of oil product, pressure, instantaneous delivery and integrated flow by the display screen on panel
Show.On the other hand, host computer also connects with weighbridge, host computer be used for the crude oil water content that is measured according to analyzer of water content with
And the crude oil weight of unloading obtains water content in crude oil.
The inventive method has the following advantages that：
The present invention solves the problems, such as oil-in-water and Water-In-Oil, due to aqueous to carrying out double principle measurements to analyzer of water content
The measurement end of analyzer can measure capacitive dielectric constant and impedance signal simultaneously, and moisture content is due to depositing when normal electricity consumption holds measurement
In the state of oil-in-water and Water-In-Oil, thus moisture content from 0-100 and moisture content from 100-0 be two different curves, impedance
Method measurement is his impedance value of direct measurement, and the linearity is preferable, and the curve of curve and 100-0 from 0-100 can overlap substantially, but
It is low precision, so with impedance method judgment curves, capacitance method measures moisture content, and both combine, and the data measured are more accurate,
Reliably.
Described analyzer of water content increases flow-compensated and temperature double compensation, solves the influence of flow velocity and temperature to measurement,
Instantaneous moisture content and average moisture content are provided in real time, and measurement result is more accurate.
