Description
Technical field
The utility model is a kind of two-phase mixture content analysis device, can be applicable to the detection of oilfield multiphase flow rates content, also can be applicable to the detection of relevant industries two-phase content metering.
Background technology
Oil-gas-water three-phase metering is an important process in field production management, measures accurately and grasps oil reservoir situation to oil well, formulates production decision, has important directive significance.With regard to the two-phase laminated flow densimetry that current domestic each oil field adopts, because gassiness in liquid phase is separated not thorough, very large on the impact of its accuracy of measuring, and in actual use because every mouthful of well, even same well different time, its fluid is all different with situation of giving vent to anger, and even fluctuates very large, therefore, it often can not produce a desired effect.
Summary of the invention
The utility model provides a kind of novel two-phase mixture content analysis device.
A kind of content analysis device, is characterized in that, the straight tube housing cavity wall of both ends open is provided with thermofin; Shell top wall is provided with the temperature sensor at two intervals, and front temperature sensor is arranged on front portion, and rear temperature sensor is arranged on rear portion; Housing lower wall is provided with a heating element, and heating element is between former and later two temperature sensors.
Principle of work of the present utility model is, different according to different medium specific heat capacity, when after two media mixing, under quantitative heat heating state, the mixing ratio that two media is different, obtaining result is exactly final heat up different, and the method is to gassiness insensitive (can not be a large amount of gas) because the specific heat capacity of gas to compare liquid very little.
Specific heat capacity formula: Q=cm Δ t
Q is heat, and c is specific heat capacity, and m is quality, and Δ t is the temperature difference
When obtaining mass rate by measuring, the temperature difference of total amount of heat that heating element produces and potpourri, can be just how many respectively by calculating the content of often kind of medium in potpourri,
Q=C1mδ1Δt+ C2m（1-δ1）Δt
Q is the thermal value of unit interval, and C1 is the specific heat capacity of medium 1, and C2 is the specific heat capacity of medium 1, and m is the mass rate of unit interval, and δ 1 is the content (number percent) of medium 1, and Δ t is the temperature difference
Q is by the performance of heating element, and detecting electric current can directly obtain, and C1, C2 are dielectric constant, and m is recorded by mass flowmeter, and Δ t is the temperature difference that former and later two temperature sensors record, and now just can obtain the content of often kind of medium.
The utility model application time, with flow measurement device with the use of; The detection of oilfield multiphase flow rates content can be applied to, also may be used for the metering solving other industry two-phase mixture, especially inaccurate to metering during liquid phase gassiness problem.The utility model contrasts with other sampling methods of tradition, and overcoming current popular densimetry affects the shortcoming large with the sampling error of sampling method by gassiness.The utility model has the function that real-time online detects, and can overcome sampling error, confidence level is higher.The utility model device is a straight length, has the pressure loss little, does not destroy the effect of fluidised form, and easy for installation.Be not stressed with the value calculated impact measured by this analysis device, so precision is high.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
Structural representation when accompanying drawing 2 is the utility model application.
Temperature sensor, 4 rear temperature sensor, 5 heating elements, 6 mass flowmeters, 7 ring flanges before 1 housing, 2 thermofins, 3.
Embodiment
A kind of content analysis device, straight tube housing 1 internal chamber wall of both ends open is provided with thermofin 2; Shell top wall is provided with the temperature sensor at two intervals, and front temperature sensor 3 is arranged on front portion, and rear temperature sensor 4 is arranged on rear portion; Housing lower wall is provided with a heating element 5, and heating element is between former and later two temperature sensors.
Straight tube housing inner diameter D, front temperature sensor 3 is 0.5 times of internal diameter D to 5 times with the spacing t1 of heating element 5; Rear temperature sensor 4 is 10 times of internal diameter D to 30 times with the spacing t2 of heating element 5.
Straight tube housing both ends are provided with ring flange 7.
When the utility model uses, front end is oil water mixture import, and rear end is communicated with mass flowmeter 6 by flange 7.The course of work: potpourri is entered by import, first records temperature through front temperature sensor 3, is then heated by heating element 5 in content analysis device, then records temperature after heating to rear temperature sensor 4, eventually passes mass flowmeter 6 and records mass rate.
Housing 1 is adopted as standard steel pipe usually; Thermofin 2 thickness, according to the content analyzer determination thickness of different model specification, ensures effect of heat insulation; Medial temperature for ensureing that temperature sensor records temperature before and after heating, the distance that need determine between forward and backward temperature sensor 3,4 and heating element 5 according to flow, caliber etc.Pipeline shell internal diameter D, front temperature sensor 3 is 0.5 times of internal diameter D to 5 times with the spacing t1 of heating element 5; Rear temperature sensor 4 is 10 times of internal diameter D to 30 times with the spacing t2 of heating element 5.Because heated fluid should have upward flow phenomenon according to thermal effect, so heating element position is below pipeline, temperature sensor location is above pipeline, thus ensures that recording temperature is medial temperature.Eventually pass mass flowmeter and record mass rate, calculated by software, finally reach the object that potpourri two media measures respectively.
