Description
Technical field
The present invention relates to liquid mass flow measurement apparatus technical field, more particularly to a kind of thermal production well steam mass flow
Measurement target-type flow sensor and the target type meter for including the target-type flow sensor.
Background technology
With conventional crude resource increasingly depleted, the viscous crude or heavy oil resources enriched using oil recovery by heating method mine reserves
It is an important measure and the long-range developing direction of prospect for crude oil volume increase.Steam soak drives with steam in thermal recovery processes
Technique oil recovery very extensively, both be required for into steam injection well inject high temperature, the steam of high pressure, make steam penetrate into oil reservoir it
In, viscous oil is transmitted to by the displacement effect of steam and by heat, is oozed after making the reduction of its viscosity, thermal expansion and partial gasification from hole
Go out and de-plugging, improve stratum filtration characteristic, so as to improve crude output and efficiency.In order to improve steam injection efficiency, and ensure equipment
Safety, it is necessary to know clearly that the steam condition of injection well in particular to reaches steam flow, pressure, temperature and the mass dryness fraction of oil reservoir,
So as to adjust the parameter of steam boiler, the steam of arrival oil reservoir is set to reach the cumulative amount of design or stop when reaching effective displacement radius
Only steam injection, to improve steam heat load and thermal recovery efficiency, and the mass flow for reaching corresponding oil reservoir is wherein reaction implanbation enthalpy
One of most important parameters, therefore need relatively accurate measurement.
If current above-ground line flow measurement of steam method is segmented by operation principle, driect type mass flowmeter can be divided into
With the major class of the formula of derivation (also referred to as indirect type) mass flowmenter two.The present widely used steam quality flowmeter of people is most
Still it is derivation formula.Wherein, with throttle differential flowmeter and flux of vortex street be calculated as core group into steam quality flowmeter be main
Stream.In addition, Coriolis flowmeter, mean velocity tube flowmeter, ultrasonic flowmeter etc. also have in flow measurement of steam and answered
With.Although by various combinations and compensation, its degree of accuracy can meet the use requirement of production scene, be due to its volume
Greatly, instrument power supply etc. limits to, and is not suitable for oil field gas injection well underground and uses, and well head test parameter again can not be directly under observation well
Actual conditions.Due to km in underground narrow space, depth, high humidity, high temperature, high pressure and the bad working environments, present one such as dirty
As the method for special miniaturization steam multi-parameter collector delivered using well head wirerope collect each parameter, then take out instrument and return
The method put or explained with application software, confirms whether relevant parameter reaches technological requirement, and each parameter is suitably adjusted if necessary, is made
Steam injection is optimal technique.Known according to scene and pertinent literature, data are inquired about in inquiry both at home and abroad, current China underground is used
Three parameters or the steam flow method of testing that uses of four parameter measurement instruments have using two kinds of vortex-shedding meter and turbine flowmeter
Method.
Vortex-shedding meter is for the stable vortex of the appearance in the saturated vapor of high void fraction, although has carried out many and has changed
Enter, but in vortex-shedding meter principle be flow measurement rate of flow of fluid, volume flow can be obtained according to throttling bore, if fluid is close
Mass flow can also be converted into known to degree.In hygrometric steam, because saturated vapor is non-single-phase, its flow and density of liquid phase,
The mass dryness fraction of density of gas phase and steam is relevant, and the current accuracy of measurement of mass dryness fraction is far below other parameters, other as derived from mass dryness fraction
Parameter, brings bigger measurement error；Being additionally, since wirerope suspention and interference in air flow makes instrument generation vibration cause whirlpool with rocking
Street is understable, and measurement error is larger in practice, substantially all more than 8%.
Another turbine flowmeter, compared to vortex-shedding meter, because it has compact conformation, the pressure difference produced to fluid
Small, measurement rotating speed is relatively easy, and measurement range is wide, the higher advantage of the degree of accuracy, therefore is also used for underground steam flowmeter
In device, but turbine flowmeter is also volume flowmeter, there is also above-mentioned measurement it is inaccurate the problem of, and in actual use,
High temperature, high pressure, high rotating speed cause turbine mechanism often to be damaged, maintenance or using the reason such as needing to re-scale after a period of time,
Therefore also do not received generally by the field.
Therefore, volume flowmeter is constant only for phase, temperature, pressure change less or be easy to compensating approach its
The fluid of density, or and density meter combination, volume flowmeter can be used to measure mass flow indirectly, but it is direct for moist steam
Obtain density difficult, the most handy direct test quality flow of mass flowmenter.
In direct measurement formula mass flowmenter, Coriolis-type, calorimetric etc. are not suitable for underground because of reasons such as volume, samplings
Use.Target type meter is another time-honored mass flowmenter, and its test philosophy is its target-type flow sensor profit
The change of mass flow is converted into the change of inductance value with dynamic magnetic core and fixed magnetic core inductance, target type meter is based on the inductance
The change of amount calculates liquid mass flow.But existing target-type flow sensor installs the knot of force measuring machine from measurement pipe side
Configuration formula, which all exists, to be not suitable in the small and deep well of caliber and suitable for being used under high temperature, high pressure, the operating mode of high humidity.
