Description
Technical field
Whether good the utility model is a kind of by detecting the petroleum pipeline temperature variations, judge oil well the instrument that turns round.Be a kind ofly to be lower than when setting value, can send the warning device of alarm signal when detecting line temperature.
Background technology
At oil field oil recovery measuring station, staff on duty often will check the temperature of oil pipeline, judges tentatively with this whether the oil well running is normal.This is that formation temperature also is carried to ground simultaneously because the interior in-place oil of oil-producing well is thus lifted to ground.The crude oil temperature of extraction just is generally between 60-100 ℃.Oil well is under normal oil recovery situation, and the pipeline of conveying crude oil can keep higher temperature.Crude oil stops to flow in petroleum pipeline, and line temperature descends, and shows that producing well has stopped production to break down.Generic failure has rod parting or petroleum pipeline leakage etc., needs investigation fault in time.At present, the work of the temperature of inspection oil pipeline is that the method that adopts hand to touch pipeline detects.This method often causes the petroleum pipeline temperature to descend when hanging down, and just can judge.At this moment crude oil stops to flow in the pipeline, and oil well breaks down to be had for a long time.Discovery time evening, incur loss through delay the Best Times of handling failure, cause influencing crude output.
Summary of the invention
The purpose of this utility model provides a kind of oil well indicator that breaks down.The utility model is installed on the petroleum pipeline that enters the station, and when the petroleum pipeline temperature descends, and temperature is when being lower than the temperature value of prior setting, and the break down indicator lamp of indicator of oil well is bright.The oil recovery workman can be in janitor's room optical viewer, obtain oil well and enter measuring station line temperature situation of change information, judge whether oil well stops production, breaks down.
The utility model is that the technical scheme that its technical problem of solution is taked is: the oil well indicator that breaks down comprises dc source E, triode BG1, triode BG2, biasing resistor R3, biasing resistor R4, variable resistor R1, thermistor R2, light emitting diode D1 and K switch are formed, the colelctor electrode of the positive pole of dc source E and triode BG2, one end of the upper offset resistance R 3 of triode BG2, the end of thermistor R2 links, the emitter stage of triode BG2 connects the positive pole of light emitting diode D1, the other end of the base stage of triode BG2 and upper offset resistance R 3, and an end of the below-center offset resistance R 4 of triode BG2 links.The colelctor electrode of triode BG1 is connected on the lead between upper offset resistance R 3 and the below-center offset resistance R 4.The end of the other end of the base stage of triode BG1 and thermistor R2 and variable resistor R1 links.The negative pole of power supply E links by the negative pole of K switch and light emitting diode D1, the other end of below-center offset resistance R 4 and the emitter stage of triode BG1 and the other end of adjustable resistance R1.Dc source E, triode BG1, triode BG2, biasing resistor R3, biasing resistor R4, variable resistor R1, light emitting diode D1 and K switch are installed on the panel, adopt lead that thermistor R2 is derived.Panel is placed on janitor's room between oil well measurement, and thermistor R2 is installed on the petroleum pipeline.Adjust the resistance value of variable resistor R1, determine the line temperature that makes light emitting diode D1 luminous.When the petroleum pipeline temperature is lower than when giving the design temperature of accent with variable resistor, the fault detector lamp that is placed on janitor's room will be shinny to inform the operator on duty.
The beneficial effects of the utility model are: the oil recovery workman can observe this instrument in janitor's room, obtains oil well petroleum pipeline temperature variations information.When the petroleum pipeline temperature drops to the temperature value of setting when following, the oil well indicator that breaks down adopts light warning, and the operator on duty can judge oil well and break down, and takes corresponding measure.Use this device, only need in janitor's room, to watch indicator can learn just whether oil well breaks down.Alleviate workman's the amount of labour, and had directly perceived, convenient, easy-operating characteristics.
