Description
Technical field
The utility model belongs to crude oil field of measuring technique, and in particular to a kind of multifunctional well head carrys out liquid detection device.
Background technology
Single-well crude oil yield and moisture content data always are important manufacturing parameter and Reservoir Data, help to understand oil
Well reservoir situation of change；Analyze oil well production dynamic, fuel-displaced, water exit；It predicts the oil development service life, instructs the daily life in oil field
Production and formulation oil reservoir development scheme；Meanwhile these parameters have great importance for reducing cost and oil recovery management automation
And practical value.
Domestic each oil field is for the metering method of well mouth of oil well yield at present, and generally there are commonly human metering, liquid level is extensive
The metering methods such as multiple method, power graph method, turbine flowmeter, ultrasonic flowmeter, electromagnetic flowmeter.The operation principle of turbine flowmeter
It is flow velocity to be first converted to the rotating speed of turbine, then rotating speed is converted into the electric signal directly proportional to flow.Ultrasonic flowmeter
Principle be when there is relative motion between fluid and transmitter, the acoustic signals of transmission and the signal that receives after being scattered by fluid it
Between will produce Doppler frequency shift.Doppler frequency shift is directly proportional to fluid flow rate.Correlative flow can be calculated using the relationship.Electricity
Magnetic flowmeter is to apply electromagnetic induction principle, and conduction is measured by the electromotive force inducted when externally-applied magnetic field according to conductor fluid
A kind of instrument of fluid flow.
Human metering, the problem of being primarily present are due to a variety of causes such as operating method, and the period of operation, error
It is bigger, and compare labor intensive；Ultrasonic flowmeter is a kind of contactless instrument, but the measurement of ultrasonic flowmeter
Circuit is more complicated than general flowmeter.Need to be 10 to the accuracy of measurement of the velocity of sound-5~10-6The order of magnitude, it is therefore necessary to have perfect survey
Amount circuit could be realized.Eddy-current flowmeter is higher to measuring medium purity requirements, and service life is restricted.
And it measures the general of moisture content and can be divided mainly into two major classes：It is that manual sampling chemically examines and utilizes sensor online respectively
Mensuration.Manual sampling at present mainly have the way of distillation and karr-Fei Xiufa etc..On-line measurement method has capacitance method, density
Method, gamma-rays method, microwave method, radio frequency method etc..Capacitance method is mixed by measuring using water and the prodigious principle of oily dielectric constants
When collaborating body and passing through two coaxial electrodes 9, in circuit the variation of capacitance obtain moisture content.Densimetry is to determine wet crude
After density, according to pure water density and pure oil density, crude oil water content is calculated.Gamma-rays method is using carbon, oxygen element to low energy γ
Radiation absorption is different, and crude oil water content is calculated by measuring carbon, oxygen content in mixed liquor.Microwave method is based on microwave and is situated between in mixing
When being propagated in matter, phase, by the measurement to phase, obtains crude oil water content because oil-water ratio difference changes.Radio frequency method
It is different with the water absorption energy of wave using oil by transmitter to measuring medium emission frequency electromagnetic waves, by accurately measuring
The intensity of radio magnetic wave judges moisture content.
But the sample time of manual sampling assay method is long, hand labor intensity is big, and randomness is strong, and error is big, and efficiency is low,
Continuous measurement is cannot achieve, can not reflect the variation tendency of crude oil water content of wellhead in real time；Capacitance method is inherently electric by sensor
The influence of appearance is unable to measure the state of " oil-in-water ", the measurement of low water-cut stage in being only applicable to；Densimetry is contained by crude oil
Sand, gassiness influence greatly, and measurement accuracy is low, are only suitable for High water cut and measure；There are ray radiations for gamma-rays method, and equipment price is high
It is expensive, difficult in maintenance；The measuring principle of microwave method belongs to the sampling to two phase flow dotted-line style in pipe, cannot reflect mixing two-phase comprehensively
The case where stream, precision cannot be satisfied requirement under the conditions of field working conditions.Radio frequency method compares the above several method, has measurement range
Width, high certainty of measurement, advantage easy to maintain, but the current cost of its equipment is higher, and pop one's head in and contact easily knot with crude oil for a long time
Wax, can not, Changqing oilfields that the content of wax high low in well yield carry out large-scale promotion.
And currently without the instrument that can measure kind of parameter simultaneously, hence it is evident that increase input cost, while installment work
Amount is big.
