In the prior art, finding out rod-pumped well optimum jig frequency value typically will be according to live indicator card, hydrodynamic face, Liquid output etc.
Data combination knowhow comprehensive analysis, and tracking adjustment in force.Thus have that artificial analytical error is big, can not supervise in real time
The deficiencies of surveying oil well output change part, cause jig frequency setting unreasonable.
Utility model content
The utility model sets irrational problem for beam-pumping unit jig frequency in the prior art, there is provided one kind monitoring oil well is defeated
The device that fluid flow changes in oil pipeline, reliable foundation is provided for Reasonable adjustment pumping unit stroke frequency of oil well.
The purpose of this utility model is achieved in that a kind of traffic trends monitor, including at monitoring modular and signal
Device is managed, the monitoring modular includes precision voltage source, heater element, temperature sensor and temperature transmitter, and the precision voltage source is used
In providing stable voltage for heater element, the calorie value sent in the heater element unit interval is constant, and by heat from
Petroleum pipeline outer wall passes to duct wall and its fluid of inside, and the temperature sensor is used for the temperature for measuring heater element in good time
Degree, the temperature transmitter are used to the temperature signal of temperature sensor being converted into current signal, and the signal processor is used for
The changes in flow rate trend of petroleum pipeline is judged according to the current signal of temperature transmitter.
To improve the heat transfer efficiency between heater element and petroleum pipeline, the heat-transfer area and petroleum pipeline of the heater element
Tube wall profile match, and cooperation in sealing contact is scribbled between the heat-transfer area of the heater element and the mating surface of tube wall and led
Hot silicone grease, the outer wall of the heater element and petroleum pipeline are enclosed with heat-insulation layer.
For ease of the temperature change of accurate measurements heater element, the temperature sensor is arranged in heater element, is used for
Monitor temperature of heating elements.
Further to improve the heat transfer efficiency of heater element and petroleum pipeline, the heater element and petroleum pipeline contact site
Position is radian and the aluminium alloy contact surface of petroleum pipeline outer wall radian identical semi-cylindrical.
The operation principle of traffic trends monitor of the present utility model is：According to heat transfer principle, what heater element was sent
Heat passes to the fluid in pipeline by tube wall, and temperature sensor is used for the temperature for perceiving heater element.When in petroleum pipeline
Fluid it is static when, the temperature of heater element can uniformly rise in certain temperature；When fluid is with certain flow rate, stream
Cognition takes away the heat that heater element is sent, and this will suppress the temperature rise of heater element, and increase along with flow velocity, and fluid is taken away
Heat increase, the temperature rise value of heater element diminishes, therefore the relation that the temperature rise value of rate of flow of fluid and heater element is inversely proportional.Root
According to the inversely prroportional relationship of rate of flow of fluid and the temperature rise speed of heater element, the trend of the changes in flow rate of fluid can be drawn, passes through length
The flow monitoring of phase, it can be deduced that the trend that fluid flow changes in petroleum pipeline, for the oil pumper punching being connected with petroleum pipeline
Secondary reasonable setting provides reliable foundation.Therefore, measurement Data Trend Monitor instrument of the present utility model, it is simple in construction, cost is low, can
By property is high, precision is high, no pressure loses, strong antijamming capability, installation uses external application formula structure, is used especially in existing producing well
On, installation or replacing can be achieved not stop production.
