Specific embodiment
In order to oil, the water in crude oil are understood separation, the device of the measurement crude oil water content of two kinds of embodiments is provided,
With reference to the accompanying drawing, the device of both embodiments is described in further detail.
Installation practice 1:
The schematic diagram of the device is as shown in Figure 1, the device includes the cup body 12 of pedestal 11 and setting on the pedestal 11.
Cup body 12 is used to measure the volume of tested crude oil, it includes a cavity, is used to hold tested crude oil in cavity.Cup
Settable volume markings on body, so that convenient, intuitive observe held original volume.
Pedestal 11 is used to measure the quality of tested crude oil, it is internally provided with pressure sensor (or weighing sensor), from
And it can measure to obtain the quality of tested crude oil.
Adhere to electric heating wire 13 on the inner wall of cup body 12, one power supply module 14 is set in the inside of pedestal；Moreover,
One electric conductor, respectively electric conductor 15, electric conductor 16 are all set on the contact surface of cup body 12 and pedestal 11.In measurement crude oil
Function rate before, first make power supply module by electric conductor 15,16 electric heating wire of electric conductor power, realization to tested crude oil
Heating enables water oil to have the line of demarcation being more clear, and guarantees that measurement is more accurate.
Meanwhile be additionally provided with control circuit in the inside of pedestal, the control circuit include a control module (in Fig. 1 not
Draw), control module is connected with pressure sensor (or weighing sensor), can receive pressure sensor (or weighing sensor) and adopts
The data of collection.In order to enable pressure sensor (or weighing sensor) directly measures the matter that obtained data are crude oil to be measured
Amount, the numerical value that pressure sensor (or weighing sensor) measurement obtains after settable cup body is placed on pedestal are pressure sensing
The zero-bit of device (or weighing sensor).
String is equipped with control switch in the current supply circuit that power supply module 14 and electric heating wire 13 form, which also controls
System connects the control switch, realizes heating in crude oil at the time of needing.
Moreover, being provided with human-computer interaction module on the outside of pedestal, the display interface of the human-computer interaction module includes containing
Water rate viewing area and parameter input area, internal wiring are connected with control module.Control module can be inputted according to parameter input area
Various data and pressure sensor (or weighing sensor) data collected, moisture content is calculated, and will calculate
To moisture content shown in moisture content viewing area.
Cup body 12, the lower surface of the contact surface of pedestal 11 namely cup body 12, pedestal 11 upper surface should be arranged to it is horizontal
Face is parallel as far as possible, so that measurement result is more accurate.
Installation practice 2:
The schematic diagram of the device is as shown in Fig. 2, the device includes pedestal 21 and the cup body 22 that is arranged on pedestal 21.
Unlike the first embodiment, the heating module in the embodiment is the electromagnetic heating that 21 upper surface of pedestal is arranged in
Coil 23, the power supply module 24 being arranged in pedestal 21 is for being electrically connected the electromagnetic heating coil 23.Cup body 22 at this time needs
Iron-containing irony cup body or cup body for alloy steel.
Its working principle heated are as follows: alternating magnetic field is generated by electronic circuit, when cup body 22 is placed above, cup body 22
Surface is to cut alternate magnetic force line and generate the electric current (being vortexed) of alternation in 22 bottom metal portion of cup body, and vortex makes cup body 22
The carrier high speed random motion of bottom, carrier with atom collides with each other, friction generates heat can, so that it is tested to play heating
The effect of crude oil.
Compared with the electrically heated heating method of embodiment 1, this kind of heating method reduces the heat energy loss of heat transmitting, heat
Energy utilization rate is higher；Moreover, heating time is shorter, working efficiency is higher.
The device of measurement crude oil water content based on above-mentioned introduction is, it can be achieved that measurement to crude oil water content, with reference to Fig. 4,
Its course of work, principle are as follows.
Firstly, parameter is arranged by hand, comprising: the density p of pure oil by human-computer interaction module0(g/cm3), water flooding it is close
Spend ρw(g/cm3), the floor space S (cm of cup body2)。
Then, produced liquid in oil well to be measured is placed in cup body, control module controls control switch closure, adds to it
Heat forms liquid level as shown in Figure 4 after water-oil separation, formation layering.
Then, after liquid level is steady, by the volume markings on cup body, the volume that measurement obtains mixed liquor is V (cm3),
Meanwhile it can measure and obtain the high h of mixed liquor (cm), the pure high h of oil0(cm) and a height of h of water floodingw(cm).At this time it is noted that the greatest extent
So that cup body is on a horizontal surface, i.e., the interface of water-oil separation should be parallel to the horizontal plane amount, could make measurement result
It is more accurate.The quality m (g) of mixed liquor is obtained by pedestal measurement.
Finally, volumetric water content f can be calculated according to obtained various parameters are measured above in control modulew(%)
With quality moisture content fw' (%), and calculation result is shown in human-computer interaction interface.Wherein:
Wherein, V0For the volume of pure oil, m0For the quality of pure oil.
That is, measurement obtains the pure high h of oil0And the high h of mixed liquor, it can must calculate volumetric water content fw；In known pure oil
Density p0, cylindrical body cup body floor space S in the case where, measurement obtain the pure high h of oil0And the quality m of mixed liquor, it can calculate
Obtain quality moisture content fw′。
Certainly, because having corresponding relationship between various acquisition parameters, other than formula (1), formula (2), therefore other public affairs can also be passed through
Formula resolves to obtain fwAnd fw′。
For example, wherein there are following relationships between each parameter:
M=m0+mw, m0=ρ0V0=ρ0Sh0, mw=ρwVw=ρwShw
V=V0+Vw, V=Sh, V0=Sh0, Vw=Shw
H=h0+hw
By these parameter substitution formulas (1), formula (2), volumetric water content f can be obtainedwWith quality moisture content fw' about difference
It can measure the function expression of obtained parameter.
