Abstract
The utility model relates to an intelligent monitoring instrument for working conditions of an oil pumping machine well pump, which can be fixed on an oil pumping machine well field for long-time recording and used as a portable monitoring instrument for itinerating usage. The utility model is composed of a load sensor, an angular displacement sensor, an electric power sensor and a recording processing unit, wherein, the load sensor is fixed right above a pressing plate arranged on a rope hanger of an oil pumping machine and connected in series with a polished rod; the angle displacement sensor, which is fixed on a bracket shaft of the oil pumping machine, is connected with the bracket shaft through a friction wheel; the electric power sensor is arranged on a power binding post of a motor. The utility model has the advantages of simple structure, reliable testing and convenient operation, when the utility model conducts testing, only a cable interface of a sensor is connected with the monitoring instrument.
Description
The utility model relates to pumping unit well pump operating mode recorder, particularly pumping unit well pump operating mode intelligent monitor.
For a long time, pumping well down-hole diagnostic techniques a large amount of theories and application study have been carried out both at home and abroad, its pumping well diagnostic equipment has also had bigger development, along with fast development of computer technology, though domesticly developed many dissimilar pumping well diagnostic equipments.But present diagnostic equipment is to be suitable for recovering the oil the movable diagnostic equipment that squad uses mostly, there is following deficiency in this instrument: 1, each installation and removal sensor during on-the-spot test, the operator need climb on the pumping unit well head and just can finish, use extremely inconvenience, long-time test also can cause personnel's contingency.2, can not carry out long-term continuous monitoring and digital record to the pump operating mode of pumping well.
The purpose of this utility model provides a kind of simple in structure, and test is reliable, gets final product the instrument that extended immobilization writes down for a long time and monitors on a pumping unit well site, also can be used as the portable monitoring instrument.Only need during test sensor cable interface and monitor connection are upward got final product, easy to operate.
The utility model is to realize like this.It is by load transducer, angular displacement sensor, and electric work sensor and recording processing instrument are formed.Load transducer is fixed on directly over the pumping unit rope hanger top board, and string is on polished rod; Angular displacement sensor is fixed on the pumping unit support shaft, links to each other with support shaft by friction wheel; The electric work sensor is arranged on the motor power wiring terminal.At load transducer, angular displacement sensor is provided with between electric work sensor and recording processing instrument composition and the recording processing instrument and is convenient to connect and the cable interface that separates, and connects with cable.
Electric current, the voltage parameter surveyed by load transducer, angular displacement sensor measured signal and electric work sensor during pumping unit of well work are together passed to the monitor that is fixed on the oil pumping unit base by cable and cable interface, and recording occurring continuously gets off.The polished rod load change curve (trilinear chart) of three specified points of surface dynamometer card, electric power curves and each stroke of the on-the-spot demonstration of record monitor pumping unit, thereby monitoring pump operating mode and balance of well pumping unit situation, and judge fault type.All be recorded in the instrument that extended immobilization writes down for a long time and monitor on a pumping unit well site but more than detect data, or in the portable monitoring instrument.The detection data of record can leave among the chip, also data can be write disk and take back and indoorly carry out detail analysis and to pumping well operating mode fault judgement.Lab analysis software is used the C language development under the windows98 environment, the result of its output can be connected with the oil well production reporting system, together output.This monitor can be analyzed straight well, inclined shaft, horizontal well operating mode.But this monitor both extended immobilization carries out long-term monitoring on the pumping unit of important production.Also can only sensor be fixed on the pumping unit simultaneously, and monitor is used for production crew as portable instrument, carry out the monitoring of many producing wells.Only need during test sensor cable interface and monitor connection are upward got final product.
The utlity model has simple in structure, but the test reliably both extended immobilization on pumping well, write down for a long time and monitor.Owing to the secondary meter portability, therefore also can be used as oil recovery squad many wells are monitored again, thereby save cost, enlarged the effect of this model utility simultaneously.
With accompanying drawing the utility model is further specified below.
Fig. 1 is that beam pumping unit and recorder are arranged schematic representation.
Fig. 2 is the angular displacement sensor scheme of installation.
Wherein 1----motor, 2----retarder, 3----crank, 4----connecting rod, 5----crossbeam axle, 6----walking beam, 7----horse head, 8----rope hanger, 9----load transducer,, 10----support shaft, 11----angular displacement sensor, 12----support,, 13----cable interface, 14----base, 15----record monitor, 16----electric work sensor, 17----friction wheel.
As seen from the figure, load transducer [9] is installed on the rope hanger [8], angular displacement sensor [11] is installed on the support shaft [10], and electric work sensor [16] is installed on the connection box for motor, and they couple together with cable by cable interface [13] with record monitor [15].Record monitor [15] can extended immobilization on oil pumping unit base [14], also can throw off cable interface [13] and become portable instrument and flow and use.
During work sensor and record monitor [15] are connected.Load transducer [9], angular displacement sensor [11], electric work sensor [16] are transferred to record monitor [15] with the signal data of being surveyed and carry out recording processing.The scene can show the ground merit figure of pumping unit and the load change curve of three special displacement points of pumping unit, and promptly trilinear chart is finished the monitoring to the pumping unit operating mode.
Claims (1)
1, a kind of pumping unit well pump operating mode intelligent monitor, it is mainly by load transducer [9], angular displacement sensor [11], electric work sensor [16] and record monitor [15] are formed, it is characterized in that load transducer [9] is fixed on pumping unit rope hanger [8] top board top, angular displacement sensor [11] is fixed on the pumping unit support shaft [10], electric work sensor [16] is arranged on motor [1] power-line terminal, at load transducer, angular displacement sensor, be provided with between electric work sensor and recording processing instrument composition and the recording processing instrument and be convenient to connect and the cable interface that separates, and connect with cable.
