Description
The utility model relates to a kind of measurement mechanism, particularly a kind of oil that the oil well on-line measurement flows out simultaneously, gas, water three-phase reducing type viscosity fluid three-phase flow meter of flow separately that is used for.
The fluid that the oil well mouth flows out is generally oil, gas, water three-phase mixed flow, before this, oil, gas, water distinguish accurate measurement will oil, gas, moisture from after.Because oil, gas, separator are bulky, cost an arm and a leg, and is strict to working environment, can only be built up in specially in the concentrated test satellite location.In the test satellite location, several mouthfuls even tens mouthfuls of wells mix separation, metering are arranged, be difficult to simple individual well accurately oil, gas, the aquatic products amount of obtaining, make the oilfield well network transformation lack reliable foundation, accurately measurement oil, gas, discharge are the oil field problem demanding prompt solutions respectively, but this technology does not still have breakthrough at present.
In view of this, how to provide a kind of convenience and the oil, gas, water three-phase of accurately measuring single port oil well flow separately, and the measurement mechanism cost is low, easy to use, the utility model grinds wound motivation place just.
The utility model designer, does a brand-new design to constitute by means of being engaged in the practical experience of all kinds of oil fields with fields such as measurement mechanism technical research production and processings for many years on the basis of feasibility study repeatedly, gets generation of the present utility model eventually.
At the deficiencies in the prior art, the purpose of this utility model provides a kind of reducing type viscosity fluid three-phase flow meter, is used for measuring effectively the single port oil well and measures oil, gas, water three-phase flow separately under the situation of not separating oil, gas, water, and is convenient and practical.
The purpose of this utility model can be by following realization, and the utility model is made of by the reducer pipe serial connection the different pipes of at least two diameters, and temperature sensor on the tube wall minimumly respectively on the tube wall of each pipe is provided with two pressure transducers.
The utility model is further characterized in that one of them pressure transducer on the tube wall of each pipe can be a differential pressure pickup; The probe of pressure transducer, differential pressure pickup flushes in tube wall; Square span of the diameter ratio of two different-diameter pipes is 1.2 to 2.5; Square best value of the diameter ratio of two different-diameter pipes is 1.5; The vary in diameter of reducer pipe is taked the slope fixed.
The utility model advantage is can measure oil, gas, water three-phase flow separately respectively under the situation of not separating oil, gas, water.During measurement, flow juice is serially connected in the fluid flowing circuit, directly provides the flow separately of individual well three-phase, and measuring method is simple, and low price is easy to operate, and easy care is suitable for in-site measurement; The accurate output of measuring individual well oil, gas, water just can provide the data of science for transforming well pattern, takes corresponding measure, improves field output, improves recovery ratio, the utlity model has important economic implications and social effect.
Further illustrate the utility model embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
The viscosity-temperature curve of oil, gas, water is an oil field parameter commonly used, these parameters of each mouthful oil well all are to record with existing measuring method, and these data also are the parameters of often using in the Petroleum Production, when utilizing the flow separately of these parameter measuring and calculating oil, gas, water three-phase, the pressure, pressure reduction and the temperature data that also need viscosity fluid, device of the present utility model are exactly to be used to measure this three kinds of data.
The utility model is made of at least two different pipe serial connections of diameter, constitute by reducer pipe 5 serial connections by two different pipes 3,4 of diameter in the present embodiment, constitute a reducer pipe, because the diameter difference, when fluid is flow through, in two different calibers, produce different pressure; Tube wall is provided with a temperature sensor 2, be used for the temperature of measuring tube inner fluid, the position that temperature sensor is laid is as the criterion with the energy measurement fluid temperature (F.T.), minimumly respectively on the tube wall of each pipe be provided with two pressure transducers 1, adopt two pressure transducers in the present embodiment, have only by two pressure transducers and just can measure pressure reduction.
One of them pressure transducer on the tube wall of each pipe can be a differential pressure pickup, because every pipe is only required a pressure value, therefore must there be one to be pressure transducer, and another also can adopt differential pressure pickup, and the probe of pressure transducer, differential pressure pickup flushes in tube wall, and pressure transducer and differential pressure pickup all have a probe, so probe is deep in the pipeline, then can make the pressure value misalignment of pipeline, so for improving measuring accuracy, probe all is not deep in the pipeline; Square span of the diameter ratio of two different-diameter pipes (d/d1) is 1.2 to 2.5, square best value of the diameter ratio of two different-diameter pipes is 1.5, diameter is than too little or too big, all influence precision, the PT-100 type that the AK-1b type that pressure transducer of the present utility model can adopt space flight main office to produce, temperature sensor can adopt space flight main office to produce.
The transitional zone of the pipe of two different-diameters preferably adopts the reducer pipe of mild transition, the diameter that is transitional zone preferably adopts progressively smooth variation, be that unit length diameter variation amount is identical and the slope feature such as have, to avoid the too fast and turbulization vortex of reducing and influence the accuracy of measurement.
In sum, the utility model can be advantageously used in measuring temperature, pressure and the pressure reduction numerical value of viscosity fluid, and can cooperate with existing oilwell parameter, calculate fuel-displaced, gas, water three-phase flow separately easily, avoid former can only oil, gas, moisture from after just can measure the complicated technology of flow separately.Obviously the utility model is the new design of a kind of novelty, progress and dark tool practicality.The above is specific embodiment of the utility model and the know-why used, if the equivalence of doing according to conception of the present utility model changes, when the function that it produced does not exceed spiritual that instructions and accompanying drawing contain yet, all should be in scope of the present utility model, explanation hereby.
