The natural gas moisture real-time measurement apparatus of technology is also related to a kind of based on the natural gas moisture real-time measurement for being mutually separated technology in pipe
Method.
Background technique
Under normal conditions, natural gas by underground mining to ground when can always carry the liquid of a part, these liquid can
Can be crude oil in stratum, in recovery process due to temperature and pressure reduces and generates condensate, water flooding, note adopt water or
Fracturing outlet liquid etc..In oil and gas industry, the mixture of the natural gas and liquid phase that produce in this gas well is known as " moisture ", it is wet
The gas volume fraction of gas is commonly greater than 90% in gas, and the gas volume fraction of most of gas well is 97% or more, and in the U.S.
Regulation, Luo-horse number (Lockhart-Martinelli number) in " the moisture metering guide " that mechanical engineer association promulgates
Referred to as moisture when less than or equal to 0.3.It can be seen that moisture belongs to the scope of multiphase flow, its essence is a kind of high gas volume fractions
Multiphase flow form.Offshore oil and gas field, shale gas field production be moisture.
Now with the increasingly increase to Natural Gas Demand, wanting for fine-grained management also proposed to the production of natural gas
Ask, and by wet gas measurement obtain gas output per well and Liquid output be realize gas well monitoring, gas reservoir management, production technology optimization and
Gas well water pumping gas production measure preferably and the basic data of effect assessment etc., is not allowed to lack.It is said from measurement angle, natural gas moisture
Measure a kind of special circumstances as multiphase flow measurement, be mutually distributed in the velocity-slip, pipe between liquid phase and flow pattern it is random
The uncertainty of the parameters such as variation, temperature, pressure all determines that wet gas measurement is a complicated multiphase flow problem, and due to
Liquid phase proportion is very small, especially sensitive for measurement error, often generates huge measurement error.Therefore, moisture one
As cannot directly be measured using traditional single phase gas flowmeter, need to carry out special grind to its measuring device and method
Study carefully.
Currently used humid gas measuring method can be divided mainly into gas-liquid not separating and measuring and gas-liquid separating and measuring two major classes.Gas
Liquid not separating and measuring be directly measure moisture using single phase gas flowmeter, and using empirical equation measured value is modified or
The method measurement flux of moisture and phase content that person uses two kinds of sensors to be combined simultaneously.Chinese invention patent application
CN103353319A, CN105675070A, CN104266702A, CN105890689A, CN105157766A and
The humid gas measuring method of the introductions such as CN106979808A is all to belong to gas-liquid not separating and measuring.As utilized gas in CN103353319A
Body ultrasonic flow rate measurement amount flux of moisture, and rule of thumb formula is modified virtual height flow；It is sharp in CN105675070A
Flux of moisture is measured with the relational expression of special-shaped venturi nozzle combination multiphase drift angle and flow and phase content；
Flux of moisture is measured using V cone flow meter in CN104266702A and measures liquid phase content with capacitance probe；CN105890689A
It is middle to measure flux of moisture using differential pressure flowmeter and measure each phase content with gamma ray sensor；CN105157766A utilizes text
The method measurement flux of moisture and phase content that flowmeter and Spindle Flowmeter are combined in mound；CN106979808A utilizes ultrasound
Wave flowmeter and target type meter combination method measurement flux of moisture and phase content.In addition, in U.S. patent Nos US7454981B2
It describes a kind of acoustic wave flow meter and gamma-ray densimeter combines the device and method of measurement flux of moisture and phase content；Europe
The combination method measurement wet gas current using coriolis force flowmeter and Venturi meter is described in the patent of invention EP2775272A1 of continent
The device and method of amount；It is described in international patent of invention WO2005040732A1 and utilizes ultrasonic flowmeter and differential pressure flowmeter
The method measurement flux of moisture combined.Moisture is all carried out using conventional gas flowmeter in the above relevant patent of invention
Measurement, although this method have the advantages that it is small in size, applied convenient for instrumentation installation, this measurement method needs to rely on
The response of conventional gas flowmeter and the relational model of flux of moisture and each phase content.Due to the complexity of multiphase flow and flow field point
The randomness of cloth, also very insufficient to the theoretical research of the flow mechanism of multiphase flow so far, could not theoretically establish can
It leans on, pervasive flow model, therefore often the relational model of this multiphase flow parameter and instrument response is to pass through laboratory data
What fitting obtained.Since the flow operating mode of different gas wells is different, the expression formula shortage universality that laboratory data obtains, and if
Site of deployment floor data carries out the fitting of relational expression, and is limited by field condition and lack magnitude Transfer Standards, substantially can not
It realizes.Therefore using the wet gas current of Conventional meters measurement coexistence of gas and liquid, the measurement model of itself just has certain limitation, only
The measurement accuracy with higher in very narrow parameter area, deviate the parameter area often and will generate it is biggish, be difficult to it is pre-
The measurement error of survey.Liquid phase content in the case of gas-liquid does not separate in moisture be normally applied capacitance probe method, gamma-rays damped method,
The methods of microwave method measures, and since liquid content is few in moisture, the resolution ratio of capacitance probe is extremely difficult to measurement request,
It will lead to biggish liquid phase error；And there is radiation pollution and safety problems for ray method and microwave method survey component, apply meeting
It is limited by country or local relevant policies law.
The gas-liquid separation measurement method of moisture is after moisture to be carried out to gas-liquid separation again respectively using single phase gas flowmeter
It is measured with fluid flowmeter.The measurement method is wet with single-phase flow flowmeter measurement since gas-liquid is kept completely separate
The flow measurement accuracy with higher of each separation phase of gas, but this is also to gas-liquid separation device that more stringent requirements are proposed.
Chinese invention patent application CN105020585A, CN106996289A, utility model patent CN206414929U, and international hair
The humid gas measuring method introduced in bright patent WO2017044538A1 etc. belongs to this type.Gas involved in these patents
Liquid/gas separator is by cyclonic separation or the mode of Gravity Separation, for moisture, since gas velocity is compared with high, liquid measure is few, liquid
The followability flowed with air-flow is stronger, in order to complete being kept completely separate for gas-liquid, needs to increase separator diameter to reduce gas velocity, increases
Add the height of separator to increase moisture in the residence time of separator, and generally requires that some reinforcings are arranged in separator interior
The structure of gas-liquid separation, therefore the volume of separator is larger, structure is complicated, is not easy to gas well mouth measurement.In addition, major diameter
Gas-liquid separator belongs to pressure vessel, and manufacturing cost is high, suffers from the higher of requirement to production technology and operating environment.
In conclusion separating measuring method does not rely on experience excessively although device volume is small to existing moisture gas-liquid
Multiphase measurement model, therefore have the shortcomings that measurement accuracy is low, narrow application range；And measured again after existing gas-liquid separation
Method is although measurement accuracy is higher, and there is separator volumes greatly, structure is complicated, manufacturing cost is high, technique and operation are wanted
It asks high, be not easy to the shortcomings that well head installation.
