Abstract
The utility model provides an oil field pumping unit indicator diagram measuring device, which comprises an inclination angle sensor, a load sensor and a data acquisition device, wherein, the output ends of the inclination angle sensor and the load sensor are connected with the data acquisition device; the inclination angle sensor is arranged on the beam of a pumping unit, while the load sensor is arranged on the polished rod of the pumping unit. The utility model realizes automatic calculation of stroke frequency and displacement of the polished rod through measuring the change of the inclination angle of the beam of the pumping unit by the inclination angle sensor as well as measures the load value of each displacement through the load sensor, thereby realizing real-time measurement of pumping unit indicator diagram; meanwhile, the utility model has the advantages of high accuracy, long service life and convenience for installation, etc. and can operate in severe environment for a long time.
Description
Technical field
The utility model relates to the measuring device of means for oilfield oil pump indicating diagram.
Background technique
Calculate and draw means for oilfield oil pump indicating diagram and need measure the shift value of oil-extractor polish-rod and the load value of each shift value correspondence.Existing measuring device is normally measured the shift value of polished rod with displacement transducer, measure load value with load sensor.Adopt backguy, Hall and near modes such as switches and displacement transducer is at present general, all there is deficiency more or less in these sensors, have can not extended immobilization on pumping unit, the pumping unit of the non-uniform rotation of not energy measurement that has, what have can't install, and what have is difficult to adapt to rugged environment, span wire system can not extended immobilization on pumping unit, Hall and deny that the uniform rotation time error is bigger at pumping unit near on-off mode can not accurately provide the foundation of analyzing the oil well situation.
Summary of the invention
The utility model provides a kind of measurement accurate, easy for installation at the deficiency that existing means for oilfield oil pump indicating diagram measuring device exists, the means for oilfield oil pump indicating diagram measuring device that can work under rugged environment for a long time.
The utility model adopts following technical solution:
This means for oilfield oil pump indicating diagram measuring device comprises dip sensor, load sensor and data acquisition unit, and the output terminal of dip sensor and load sensor all is connected with data acquisition unit.
During use, dip sensor is installed on the crossbeam of pumping unit, load sensor is enclosed within on the polished rod of pumping unit.Dip sensor is the sensor of an inclination angle and electric current (or voltage) conversion, as change its output 4-20mA electric current to+60 degree from-60 degree (level is 0 degree).In the pumping unit running, the variation of crossbeam angle is consistent with dip sensor.The electric current (corresponding with the inclination angle) that the internal processes of data acquisition unit measures according to the stroke and the dip sensor of pumping unit can calculate the polished rod shift value of pumping unit every bit in operation period.The load value of each shift value that records according to shift value and load sensor can calculate and draw out indicator diagram.According to dip sensor maximum, minimum transition point, calculate the time of pumping unit operation one-period again, and calculate the periodicity (being jig frequency) of per minute pumping unit operation.
The displacement that the utility model calculates stroke and polished rod automatically by the variation at dip sensor measurement pumping unit crossbeam inclination angle, measure the load value of each shift value by load sensor, can realize real-time measurement to pumping-unit workdone graphic, have advantages such as accuracy height, life-span be long, easy for installation simultaneously, can under rugged environment, work for a long time.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, dip sensor, 2, load sensor, 3, data acquisition unit, 4, crossbeam, 5, polished rod.
Embodiment
As shown in drawings, the measuring device of means for oilfield oil pump indicating diagram of the present utility model comprises dip sensor 1, load sensor 2 and data acquisition unit 3, and the output terminal of dip sensor 1 and load sensor 2 all is connected with data acquisition unit 3.Dip sensor 1 is installed on the pumping unit crossbeam 4, and load sensor 2 is installed on the oil-extractor polish-rod 5.
In the pumping unit running, the variation of crossbeam angle is consistent with dip sensor 1, the electric current of dip sensor 1 output is inserted in the data acquisition unit 3, and data acquisition unit 3 internal processes calculate the shift value of the polished rod 5 of an interior every bit of operation period of pumping unit according to the stroke of pumping unit and the electric current that measures (corresponding with the inclination angle).The load value of each shift value that records according to shift value and load sensor 2 just can calculate and draw out indicator diagram.According to angular displacement sensor maximum, minimum transition point, calculate the time of pumping unit operation one-period, and calculate the periodicity of per minute pumping unit operation, i.e. jig frequency.
