Mean power poor, be automatically adjusted the speed of oil pumper rotating speed by the size of power difference, with difference power formed closed loop control
To reach constant level oil pumping.
Generate indicator card: the drafting of conventional indicator card needs to grasp at the scene with special instrument and professional staff
Make, but this oil pumper solves this difficulty, it is only necessary to oil recovery work or opens hander on monitored picture at the scene just can be straight
Connect and demonstrate indicator card.Oil recovery work is facilitated more to be fully understood by duty under rod-pumped well.By gathering in converter constantly
Formula is brought in torque intoDrawing polished rod load, Real-time Collection also stores up starting point to eventually
Load when point, descending starting point to terminal and displacement, draw uplink and downlink the curve of load, according to sucker rod sectional area,
Oil pipe sectional area, coefficient of elasticity, lower-continuous mapping, fluid column weight bring formula estimation loss of plunger stroke into, determine up opening a little and descending
Open a little in the position of displacement coordinate, it is possible to achieve the drafting of indicator card.
Calculate Liquid output: be identified analyzing to indicator card by software, calculate the suction factor of pump, discharge factor and fill
Full factor, oil pump diameter, piston stroke length, stroke of polished rod, jig frequency are brought formula into and are calculated the lifting rate of pump, thus obtain conversion
Effective discharge capacity, can meet the measure of production, it is achieved instruct the requirement adjusting development plan.
Manually adjust ginseng: when oil pumper needs manually to run, the stroke of oil pumper, jig frequency, mistake can be revised by hander
Carry and take out frequency between shutdown value, adjustment, arbitrarily change by production requirement without shutting down, can start and stop oil pumper, operation at an arbitrary position
Very convenient.
Between take out: for function can be taken out during Liquid output wretched insufficiency between realizing, system press cycle detection downhole data
Automatically take out frequency between calculating, fully improve pump efficiency.
Fault alarm is shut down: frequency converter failure is shut down, electric current is shut down more than setting value, sucker rod drags have no progeny shutdown, motor
Overheating fault is shut down, casing pressure cancel closedown.Institute is faulty all can be shown and alarm at hander and monitoring system.
Hander monitors on the spot: hander start input address selects respective picture to observe oil pumper after carrying out docking successfully
All data and revise parameters during operation, show that work figure also can show on hander, facilitate Field Force to analyze reference.
Remotely monitoring: the data after controller focuses on are uploaded onto the server by GPRS remote transmission device, by man-machine
Objective interface shows that all data and warning, support alarm history are checked, support history curve to check and exported printing, support report
Table function, support amendment and the interpolation of oil well static data, by different Department formation user rights.
