Description
Technical field
The utility model belongs to the testing apparatus that petroleum industry is recovered the oil, particularly walking-beam pumping unit and quickens sensing collection balance power measurement arrangement, is applicable to the pumping production well.
Background technology
At the oil well of petroleum industry with pumping production, the balanced ratio of oil well has reflected the working condition of oil pumper.Because the load of oil pumper is along with oil well down-hole fluid column and other parameter constantly change, thereby need often to measure balanced ratio and counterbalance weight is adjusted, motor load is remained in the reasonable range, not only can improve the smooth-going degree of running, the prolongation maintenance period of each system of oil pumper rod pump, and can obtain higher motor power factor, reach purpose of energy saving.The foundation of the on-the-spot at present balance of well pumping unit test of using, it mainly is the apparent current ratioing technigue, be the ratio of upstroke maximum current and down stroke maximum current, this method is simple, but the balance judgment accuracy is subjected to than multifactor impact, mainly contain: 1, operate miss, reometer show the instantaneous value that electric current changes continuously, exist the artificial collimation error; 2, because current of electric is subjected to the load variable effect bigger, bump and hang and during shock load such as wheel box commutation when running into vibrations, bar pump, can cause current of electric anomaly peak to occur, judge balanced ratio with the reometer method this moment, causes the high illusion of balance of well pumping unit rate easily; 3, when the balance of well pumping unit piece is descending, if quality of balance is bad, can exist the counterbalance weight dragging motor to do the situation of negative work, because reometer can only show that positive can not show negative power, the error of positive and negative addition is quite big, this moment is if carrying out balanced ratio according to the reometer method judges, tend to the result that makes mistake.More than three cause descriptions the apparent current ratioing technigue judge and the deficiency of balance of well pumping unit rate to have influenced the correct adjustment of balance of well pumping unit rate, cause the waste on the energy.
Summary of the invention
The purpose of this utility model provides walking-beam pumping unit and quickens sensing and gather the balance power measurement arrangement, overcomes the problem of present balance of well pumping unit rate in measuring in real time, makes the real-time measuring operation of balanced ratio convenient, data are credible.
The present technique solution can reach above-mentioned purpose: walking-beam pumping unit acceleration sensing is gathered the balance power measurement arrangement and is comprised measurement main frame, acceleration Acquisition Instrument and switch board, measures main frame and is connected with switch board, acceleration Acquisition Instrument and the wireless connections of measurement main frame.
Use the utility model compared with prior art to have following advantage: the principle of work of this instrument goes up bottom dead centre and power area-method judgement balanced ratio according to adopting acceleration transducer to measure.The power area-method is the determination methods more comprehensive and accurate than the apparent current ratioing technigue, by the performance number in jig frequency of real time record oil pumper, accumulates the power sum of upstroke and down stroke respectively and compares, and draws balanced ratio.Three deficiencies that this device avoids the apparent current ratioing technigue to exist effectively draw balanced ratio accurately.The power area-method requires accurately to distinguish to go up bottom dead centre, and is especially even more important when the jig frequency of oil pumper is very fast, and that manually judges last bottom dead centre exists personal error inevitably.Place an acceleration Acquisition Instrument at the counterbalance weight place, the operating condition that acceleration pick-up transducers in the Acquisition Instrument is gathered counterbalance weight in real time, judge after bottom dead center by scm software, to go up lower dead point position by the collection wireless communication module and send to the measurement main frame in real time, measuring operation is convenient, data are accurate.
