Abstract
The present invention relates to an intelligent control system for pumping unit in oil field. Said system is characterized by that man-machine interactive interface is connected with industrial control machine by means of adapter; input end of industrial control machine is connected with signal-data converter by means of cable, and its output end is connected with data-signal converter by means of cable; the input end of signal-data converter is connected with flow signal acquisition sensor and level sensor by means of cable; the output end of data-signal converter is connected with motor control system by means of cable, and the motor control system is connected with motor; in the interior of industrial control machine a pumping unit intelligent control program is set.
Description
One, technical field: the present invention designs a kind of oil-field oil pumper control technology, especially intelligent controlling system for beam-pumping unit.
Two, background technology: at present, at each elephant of China very strong blowing ability is arranged unlike the oil field in the Middle East, the stripper well of quite a few hyposmosis is arranged, the situation of feed flow deficiency can appear in wherein reciprocating type rod pumping system.So-called feed flow deficiency is that oil well liquid level is lower than the oil well pump suction inlet, this situation occurs and will make oil rig sky occur to take out phenomenon.If oil rig sky occurs and takes out, will waste electric energy, will cause wearing and tearing, the losts of life such as oil well pump, sucker rod, oil pipe simultaneously.According to relevant report, the operational efficiency of oil pumper is low especially, is 25.96% in China's av eff, and external average level is 30.05%.Take out between to the experience solution of this phenomenon being in the most of oil field of China, between take out control original way be to send someone to be timed to oil well to remove the start-stop oil pumper, make oil pumper open a period of time and stop a period of time, even in developed country, also also have many oil wells to adopt this manual control mode at present, so that solve the poor efficiency and the waste problem of oil pumper.This way will be sent someone the well site operation several times every day, through test of long duration just can find out be fit to each oil well between take out rule, time-consuming.So the oil well that has has been introduced timing watch; only need to set open, stop time; just take out control between automatically carrying out; though this has reduced manually; but still can't solve the variation that the ability to work that makes oil pumper dynamically responds the oil well load; reach take out, the stopping time interbody spacer is optimization, may influence oil well yield in addition simultaneously.
Three, summary of the invention: the purpose of this invention is to provide and a kind ofly can judge timely and effectively under the situation that does not influence oil yield whether well head is fuel-displaced, fast, control the start-stop time of oil pumper effectively, make the well time that stops of oil pumper the longest, the intelligent controlling system for beam-pumping unit that well opening time is the shortest, it has solved the shortcoming that present other technology exists, the object of the present invention is achieved like this, it is by man-machine dialog interface, adapter, industrial computer, signal data converter, data-signal converter, flow signal acquisition sensor, liquid level sensor, electric machine control system, motor is formed by connecting, and man-machine dialog interface is connected by adapter with industrial computer; Connecting signal data converter in input end of industrial control machine by cable, its output terminal is connecting data-signal converter by cable; The input end of signal data converter links to each other with liquid level sensor with flow signal acquisition sensor by cable; The output terminal of data-signal converter is connected with electric machine control system by cable, and electric machine control system is connected with motor; The oil pumper intelligent control program is housed in industrial computer.
This systemic-function is mainly realized by computer-controlled program.The major function of a complete set of system is to judge have oil not have oil by flow switch, stops the time according to initial value dynamic calculation optimum, removes to control oil-well motor with result of calculation, and is furnished with man-machine interface and dynamically shows oil pumping process.
This technology adopts the industrial computer input end to connect signal data converter, flow signal acquisition sensor and liquid level sensor, output terminal connects the mode that data-signal converter and electric machine control system are controlled pumping-unit motor, can judge timely and effectively under the situation that does not influence oil yield whether well head is fuel-displaced, control the start-stop time of oil pumper quickly and efficiently, make the well time that stops of oil pumper the longest, well opening time is the shortest.The optimum well time of stopping can be selected and control to this control system, reach the power consumption minimum and do not influence oil well output again, prolong equipment life simultaneously, as long as select suitable initial value, required result can quick and precisely calculate in this system, and it optimizes the result and follows the tracks of the variation of production technology measures such as geologic condition, oil well condition, water filling, remains a dynamic optimum and stops the time.Except time ratio is stopped in optimization, optimize simultaneously and stop well time and total cycle of well opening time, as stop opening in 30 hours 10 hours with stop opening in 300 hours that to stop time ratio in 100 hours be the same, but their optimization cycle is different, optimization cycle calculates with the method for " blind person's climbing method " on the mathematics, the workman more or less has this experience generally speaking, is not poor too much as long as determine initial value, can determine that the best stops the time through above-mentioned optimization.
Four, description of drawings: Fig. 1 is the intelligent controlling system for beam-pumping unit synoptic diagram, among the figure 1, man-machine dialog interface 2, adapter 3, industrial computer 4, signal data converter 5, data-signal converter 6, flow signal acquisition sensor 7, liquid level sensor 8, electric machine control system 9, motor
Fig. 2 is oil pumper intelligent control program figure
Five, embodiment: in Fig. 1, man-machine dialog interface 1 is connected by adapter 2 with industrial computer 3; Input end at industrial computer 3 is connecting signal data converter 4 by cable, and its output terminal is connecting data-signal converter 5 by cable; The input end of signal data converter 4 links to each other with liquid level sensor 7 with flow signal acquisition sensor 6 by cable; The output terminal of data-signal converter 5 is connected with electric machine control system 8 by cable, and electric machine control system 8 is connected with motor 9; The oil pumper intelligent control program is housed in industrial computer 3.
In Fig. 2, the oil pumper intelligent control program is:
